Within our setting we have daily checks covering all areas of the building. These are to be done at the beginning and end of each day. We have risk assessments as well which we use to prevent hazards. We keep all hazardous chemicals in the cupboard in the kitchen with a lock on the door. Also the children are not aloud into the kitchen. There is a gate with a lock on to stop them getting through. We have child friendly scissors which are only used under adult supervision. The cutlery that we provide the children with is plastic and so are their plates, bowls and cups. All the taps on the sinks that the children have access to have a block on them. This prevents them from getting to hot so the children cannot get burned. We have socket covers on all plug sockets. We do all the cleaning once the children have left the setting to prevent slips and trips. We have a lock on the front gate and back gate. This is so the children can not get out, but also so that nobody can get in without being let in. ll the radiators have covers on so the children cannot burn themselves on them. Any free standing unit’s the we have, have got locks on the wheels so they cant be moved or run over a child’s foot. We have things on all of the doors to prevent children shutting their finger in them. We make sure we think about all the risks within our setting and we address the problem to prevent an accidents happening. We have policies and procedures in place cove ring all factors of the setting, ensuring we make it as safe an environment for the children and employees as possible.

Discrimination of African Americans in Michelle Alexander’s The New Jim Crow

The New Jim Crow: Mass Incarceration in the Age of Colorblindness, by Michelle Alexander, is a book about the discrimination of African Americans in today's society. One of Alexander's main points is the War on Drugs and how young African American males are targeted and arrested due to racial profiling. Racial profiling, discrimination, and segregation is not as popular as it used to be during the Civil War, however, Michelle Alexander digs deeper, revealing the truth about our government and the racial scandal in the prison systems.She writes, â€Å"†¦ in major cities wracked by the drug war, as many as 80 percent of young African American men now have criminal records and are thus subject to legalized discrimination for the rest of their lives. These young men are part of a growing undercaste, permanently locked up and locked out of mainstream society. (Alexander pg. 7)† In our nation today, we hardly think of discrimination as being a big issue, but Alexander shows tha t our prison systems are proof of discrimination.Other studies help support this by saying that, â€Å"African Americans make up 57 percent of the people in state prisons for drug offenses. † This colorblindness has become a part of our daily lives. We can not see how much our nation is affected by racism until we stop and actually listen to those who have fallen victim of being placed in prison due to their skin color. Not only are African Americans racially profiled, they are also punished much worse than Caucasians by being sentenced longer in prisons and losing all of their rights once they are released back into society.As if it is not bad enough, being in prison for many years and having a felon label tattooed on their foreheads, colored people are exiled from everyday life. They can not vote, they can not buy a house, they can not work in many places, they can not have a normal life. They are looked at differently by society in turn putting them in a racial caste syste m, while we go about our lives over looking this mass incarceration. If I were to ask, â€Å"Is racism current in the world today?‘ Many Caucasians would say no, while African Americans would say yes. This is due to the fact that we are all colorblind. The worst part of this mass incarceration is that African Americans who have been placed in prison and are now free have no voice. They are unable to protest against this terrible system because they have no rights. Thus making them go back to their old ways, because it is what they know, therefore creating a cycle of mass incarceration. So how do we as a nation stop this disgusting system?Noel Sheppard, the Associate Editor of NewsBusters, wrote an article on Oprah Winfrey's interview with Will Gompertz from BBC on racism. Sheppard wrote that Oprah's view is that, â€Å"†¦it's older white people that are the problem, and once they die, racism end. † The problem with this is that families keep traditions, and they a re loyal to each other, so if the grandfather is racist then his children are most likely going to be racist, so on and so forth. This is not true for all families, however it is for most.Let us just say those points of view are a generational curse that should be stopped, but that is not the solution to stop the war on drugs and the racism that tags along. Neill Franklin, a Baltimore ex-police officer who is Executive Director of Law Enforcement against Prohibition, asked a question as he was being interviewed with Judith Brown Dianas, Co-Director of the Advancement Project by Roland Martin, â€Å"What part of our current policies of drug prohibition are working? Do we have less crime, less addiction rates, less disease, less overdose rates?†He goes on to say, â€Å"No, none of it is working and the only solution to ending the drug war is to end the prohibition of drugs, that means legalization. † This is a good point, however, then it would be a tax issue on the drug s, and there would be more problems making bills to allow people of a certain age to use them, how much you can and can not have at one time, etc.. and then the whole racism problem would not be stopped, yet again because people are still going to abuse those privileges and African Americans will still be the primary target.The only way to end this issue is step by step. In Michelle Alexander's conclusion, she goes on to say that, â€Å"What we need is an Underground Railroad for people coming out of our prisons to bring them back into society, instead of permanently stigmatizing and marginalizing a whole underclass numbering the millions. † I agree with her. We need to help those who are out of prison due to being victim of mass incarceration become normal, active citizens of the United states.

Dear Doug 1

Dear Doug I am glad to hear that you are settled in and that everything is well. It is also a relief to hear that you and your roommate seem to be getting along and I hope that your friendship with Nathan will grow. I have thought about your questions and decided on some ways to help you explain, and help Nathan interpret and understand Christianity. In my life I have experienced the same situation you mentioned about Christian terminology and what it means to be a Christian.I grew up in a Christian home under Christian principles and it had not occurred to me â€Å"why do I believe in Christianity†? Of course this did not occur to me until I was older and had thought about it for some time. I thought about this world and how it could have been created not by mere chance but by something or someone far more intelligent than mere humans, not by chance. This universe and everything in it was created with superior intelligence and for a purpose.I looked into Christianity and saw how God created the earth; a being far above humans because we were made by him; a perfect powerful all knowing being who created us in his likeness to serve a distinct purpose in this world, rather than leaving it up to mere chance. I knew there had to be a reason for this world and a good one! I looked farther into Christianity and the story of how God created the earth called the Gospel. I am sure you have heard of the Gospel and read the story, but you must take into account many things before you explain it to a non-Christian.Many non-Christians are not familiar with Christian terminology because they have not looked into Christianity and read the Bible to understand our belief, and we as Christ’s followers must explain the Gospel in a simplified way for people who are not familiar with certain Christian terminology so they can understand the concept and become more familiar with the terminology. One way you can simplify the meaning of these words is to define them and s implify them in a way that you clearly present the meaning of that word.An example would be instead of saying we are sinful people, you could say we are disobedient or you could define sin as bad behavior or actions that you commit. Use words that people use on regular bases to define a certain word, which will give them a better understanding since they already understand the correct meaning of that word to better understand any Christian terminology. You may not have known, but you have already or at least started to formulate and create your own worldview. A worldview is exactly what it sounds like, it’s the way we interpret, understand, and our opinion about the world and how we view it.A worldview is how you see the world and your opinion or idea of reality. Norman Geisler and William Watkins give a very well thought out worldview explanation and an example that may help you understand, â€Å"It is an interpretive framework through which or by which one makes sense of t he data of life and the world. † A worldview is like a pair of glasses and the only way to view the world and everything in it, is through the pair of glasses, and like the prescription of glasses, everyone’s worldview is different. Now that I have given you an understanding of a worldview I will do my best to explain to you what a Christian worldview is.A Christian worldview would basically be a Christian influence on how you shape your worldview. A Christian worldview would be based on Christian principles that you’ve read and learned about in your life. How you view the world and reality would be based on Christian morals and ethics rather than a different world view based on society’s standards. A Christian worldview is typically a brighter more positive outlook on life rather than a worldview not based on Christianity; it gives you more of a purpose and reason for the questions what? , why? , and how? Your last question I also struggled with and still do from time to time.We all know that we have accepted Christ into our hearts but the greater reason is why. I have asked this question to myself many times and sometimes feel over whelmed, but there is a reason. Take a look around this world; it is full of proof and purpose. The intelligence that was required to form this world was more than mere chance but above normal human intelligence. God a supernatural being who is perfect created this earth for a purpose and with intelligent design. You yourself were made for a purpose and you yourself are far more complex to be created out of mere chance.Also the sacrifice that God made for us to have another chance even though we wronged him, beyond human means of forgiveness, it amazes me how someone could love us so much; still wanting to obtain a relationship with us. Even when we show disobedience and repetitively wrong God he will still forgive us if we truly and honestly ask for forgiveness from him. He gave us free will to make our own decisions to disobey him or to love him. I hope that this letter has assisted you in understanding your questions and I would be glad to attempt and answer more, so keep thinking and writing! I hope everything with your roommate goes well, Daniel

Philosophies of Nursing Research Paper Example | Topics and Well Written Essays - 500 words

Philosophies of Nursing - Research Paper Example There exists a unique interplay between the patients’ beliefs and the effectiveness of the medication. The workability of any form of medication depends grossly on the patient’s state of mind and on the conviction that a particular medication is effective to alleviate the disease (Sobia 2014). The dilemma for life and death necessitates interventions to rehabilitate the psychological inclinations of the patients as a primary move to ensure the effectiveness of medication. Achievement of psychological peace is a prerequisite for the effectiveness of medical drugs. It is the responsibility of the nurses to foster a conducive psychological peace o the before the administration of medication. The Nightingale philosophy of nursing is 1880 nursing philosophy of Florence Nightingale. Nightingale philosophy touches closely on the nurse-patient relationships and the distinctive roles of nurses in the health of the patients. This philosophy delimits the roles of nurses from that of the physicians (Sobia, 2014). The propositions of the Nightingales nursing philosophy formed the basis of ‘what to do’ and ‘what not to’ for nursing professionalism. The philosophy fostered comprehensive exposition of the roles of nurses in keeping a continuous check on the progress of patients as a guide to inform necessary changes for the checks and balances in the performance of medication. The stance taken by the Nightingale philosophy draws a relationship between the effectiveness of medication and the patients’ environment. It posits that the cleanliness of the patients’ environment ranging from the cloths to the bedding is pre-determinants of the successful response to medications (Sobia, 2014). Furthermore, it asserts the protective role of nurses on the lives patients’ .the proponents of the nightingale philosophy advocate for a change in the patient environment as a means of achieving the optimal effect of medication .it forms an integral aspect of

Compare the socities and governments featured in George Orwell's 1984 Essay

Compare the socities and governments featured in George Orwell's 1984 and Ray Bradbury's Farhenheit 451 - Essay Example Through such features, the authors position their works among their target audience as appropriate pieces of literature. George Orwell employs such features thereby developing a unique piece that coincidentally portrays specific social and government features that are characteristic of dystopian works thereby achieving a similarity with Ray Bradbury’s Fahrenheit 415. The discussion below is therefore an analysis of the features thereby portraying the similarities and differences in the two societies created by the two authors (Ray 12). George Orwell positions his story in an airstrip in a society formerly known as the Great Britain. The author portrays a post apocalypse United Kingdom in as the government goes archaic thereby imposing restrictive policies and increased surveillance of the population. The new authoritarian government banns independent thought thereby controlling the thoughts of the people (Orwell 21). The government has invented both a new category of crime kno wn as thought crime thereby punishing independent thinking people. Additionally, the society has invented yet a new language. The same is the case in Fahrenheit 451 where the new government enjoys massive control of the people by limiting the liberties thus gaining more control. The two societies and governments have various similar features that arise from the nature of the novels. As with any other dystopian novel, the authors set their stories in a futuristic society. The novels seek to address specific social features that require particular positioning. Unlike many other novels, dystopian stories address specific themes not already witnessed in the contemporary society. To validate such claims, the authors therefore position their stories in a futuristic society in which most of their target readers are yet to experience. The ignorance about the feature therefore validates their portrayal of the various themes in such works. Fahrenheit 451 is in a future American society while Nineteen Eighty-Four is set in a future Great Britain. With such placements, the authors are therefore free to manipulate the facts in their stories by presenting plots that would otherwise prove unrealistic in the contemporary democracies such as the United States and the United Kingdom. The two societies have similar structures, with the numerous government legislations; the people therefore develop new social structures in order to accommodate the new political regimes. In Nineteen Eighty-Four, the new authoritarian government under the leadership of the Big Brother imposes various regulations most of which limit the liberties previously enjoyed in the countries. The new government bans any political outfits thereby developing an authoritarian political system. The government for example revokes all the liberties key among which is the freedom of thought. The government develops an effective mind control system that acts as a surveillance tool. The government therefore enjoys a d edicated surveillance of the population thereby monitoring every action in the state. The perpetual war in the society destabilizes peaceful coexistence as the people in the new society live in fear of abduction and public murder by the new regime at any time in case of a violation of the set regulations. The new government is remorseless and treats the people harshly with the view of eliminating any form of resistance. As is characteristic with all dictatorial

Open System Approach to Organizations Essay Example | Topics and Well Written Essays - 1250 words - 1

Open System Approach to Organizations - Essay Example The company will be used as a case study to answer the questions in the subsequent paragraphs. An open approach system to organization implies that an organization interacts with its outside environment, which in turn influences the structure and operations of the organization. The fact that an open system interacts with the outside environment implies that an organization is an open system should always adapt to changes in the environment. For a long time, Icy Foods Ltd. has been operating on informal basis judging, by the way, operations are loosely divided into five departments with no clear-cut framework. Moreover, the company used to accept orders with less or no regard to quality or quantity specifications of the product. This lack of organization explains why the company lacked customers from major supermarket chains. The other apparent misgiving that characterized Icy Foods Ltd. is the lack of clear division of labor and specialization. This fact is inherent in the way the company conducts job rotations (Weiner, 2002). Job rotation is not a good concept because it does not give the employees the chance to gain experience in a given line of duty. The fact that the company did not embrace quality and efficiency in its operations negatively affected its business performance. Before the takeover by Megastores Plc., the company had adopted an organic organization structure in managing the various operations. The management, prior to the takeover, operated an open-door policy. The management was keen on hearing employee’s ideas on new products and operational improvements. There was also a flexible approach to handling employees’ issues such as working hours and leave. After the successful takeover, the management came up with a raft of new changes that were more bureaucratic as opposed to the organic system that the management had used to all along.

The role of Student Non-Violent Coordinating Committee (SNCC) in Research Paper

The role of Student Non-Violent Coordinating Committee (SNCC) in increasing the social equality in United States - Research Paper Example ons ultimately triggered SNCC and SCLC to be at prospects, the two establishments functioned next to each other all through the initial years of the civil rights activity. Student Nonviolent Coordinating Committee (SNCC), also known as (after 1969) Student National Coordinating Committee, United States political group that presented a main role in the civil rights action in the 1960s. Started as an interracial cluster encouraging nonviolence, it implemented better militancy overdue in the decade, reflecting countrywide fads in black activism. 1 The Student Nonviolent Coordinating Committee was established in initial 1960 in Raleigh2, North Carolina, to make the most of the results of a rise of sit-ins in Southern college places, in which black students turned down to go away from dining places wherein they were refused a job depending on their ethnic group. This type of nonviolent protest carried SNCC to nationwide interest, tossing a severe public light on white racism in the Southwest. In the many years following, SNCC reinforced its endeavors in local community group and backed Freedom Drives in 1961, together with the March on Washington in 1963, and activated for the Civil Rights Act (1964). In 1966, SNCC formally threw its assistance behind the much wider protest of the Vietnam Struggle. 3 As SNCC grew to become a lot more energetic politically, its people confronted amplified hostility. In reaction, SNCC migrated from a belief of nonviolence to certainly one of better militancy after the mid-1960s, as a supporter of the burgeoning â€Å"black power† activity, an area of late 20th-century black nationalism. The transition was personified by Stokely Carmichael, who substituted John Lewis as SNCC president in 1966–67. Although many initial SNCC participants were white, the newfound focus on African American identification resulted in larger racial separatism, which frightened parts of the white local community. More-radical aspects of SNCC, for example,

Read questions and write answer about a few sentences - Assignment Example Statistical research involves the collection, interpretation, organization, analysis, and presentation of the data. In this case, statistical research requires careful planning of time and budgeting of resources involved in a successful outcome. In the article WSJ, the author takes us through two weddings based on the financial input. The expensive one does not result in a successful marriage while the less expensive one in most cases makes a successful marriage. Consequently, it can be concluded that what results from a successful statistical research are careful planning and wise spending of the available resources (Arends 3). In an article from Fivethirtyeight.com, the author revealed how the census bureau does clean their messy data. He claimed that the bureau do revise their data where they identify the possible errors in the name of the people by using an algorithm. In the event that a couple who is registered as an opposite sex couple but the name registered under male section appears to be a female name, the bureau considers the individual as the woman. Therefore, they assume that the couple is of the same sex hence changes its registration to same-sex marriage. The bureau argues that though doing this is unethical; the overall effect is minimal since it makes their data more accurate and realistic (Casselman). In the article written for GSA, the insights that I got concerning writing a recommendation letter is that it must be brief and in support of the candidate by emphasizing on the strengths, characters and weaknesses of the candidate. In regards to the other article designed for the students, the insights that come out clear are building rapport with the relevant professor and seeking for the recommendation letter in advance of the due

Nursing Informatics Coursework Example | Topics and Well Written Essays - 500 words - 4

Nursing Informatics - Coursework Example Nurses must integrate the nursing informatics into their professional lives to enable them develop their nursing systems for specific needs such as in the psychiatry department. Restructuring of job descriptions helps the health workers perform their roles with great competence due to their specialization and advanced skills in their department. For instance, there are nurses involved with health education, mental health counseling, and occupation health among others. The long care support and services training facilitate knowledge to make sure that the patient receives high-quality service and promote the independence of individuals who are beneficiaries of the service. A performance appraisal for health care nurses is very important as rewarding them boosts their morale to provide high-quality services (Careeronestop.org, 2015). The nurse performance appraisal tools assist in determining the key areas of responsibility in which each nurse can perform perfectly. The techniques involve getting the information and rating each nurse with respect to the dedication and contribution to the organization, which helps to make judgments when promoting. The nursing s uch as the dressing code policy, confidentiality, and commitment policies are important in ensuring quality services for the patients. Some other professional guidelines are keeping short nails, avoiding the use of strong fragrances, and sometimes-personal cell phones are not around during the care for the patients. Electronic health records and use of computers is important for all health professionals, especially the nurses. Micron technology (MU) enables the use of charts to pass information such as patient preferred pharmacy prescriptions, which can be sent to the pharmacy after the patient is discharged. The other important part of the Mu that facilitates quality health services is the

American Airlines Flight Case Study Essay Example for Free

American Airlines Flight Case Study Essay Cause(s) of Accident The National Transportation Safety Board (NTSB) determined that the probable cause of this accident was the asymmetrical stall and the ensuing roll of the aircraft because of the uncommanded retraction of the left wing outboard leading edge slats and the loss of stall warning and slat disagreement indication systems resulting from maintenance-induced damage leading to the separation of the number 1 engine and pylon assembly at a critical point during takeoff. The separation resulted from damage by improper maintenance procedures which let to failure of the pylon structure. Structural and Mechanical Factors After a thorough examination of the pylon attachment points, fractures and deformations at the separation points in the forward bulkhead and thrust link were all characteristic of overload. Testimony indicated the forklift was not powered for a period of time because it ran out of fuel. Post accident forklift tests showed that under these conditions leakage would allow a drift down of 1 inch in 30 minutes. Movement of 0.4 inch or less would produce a 7 inch fracture at the flange. Contributing Factors The design and interrelationship of the essential systems as they were affected by the structural loss of the pylon contributed to this accident. Flight control, hydraulic, and electrical systems in the aircraft were all affected by the pylon separation. When the engine separated from the pylon hydraulic pressure and fluid were lost and not recoverable. The separation also severed the electrical wire bundles inside the pylon which included the main feeder circuits between the generator and the No 1 a.c. generator bus. The flight crew was unable to restore power to the aircraft. The failure of engineering to ascertain the damage-inducing potential of a procedure which deviated from the manufacturer’s recommended procedure was another contributed factor. The procedure in question was the removal of the pylon attaching hardware and the positioning of the forklift. As a result, maintenance personnel altered the sequence of hardware removal. Investigation Board Findings The engine and pylon assembly separated either at or immediately after liftoff. The flight crew was committed to continue the takeoff. The aft end of the pylon assembly started to separate in the forward flange of the aircraft bulkhead. The structural separation of the pylon was caused by a complete failure of the forward flange of the aft bulkhead after its residual strength had been critically reduced by the fracture and subsequent service life. The length of the overload fracture and fatigue cracking was about 13 inches. All electrical power to the number 1 a.c. generator bus and number 1 d.c. bus was lost after the pylon separated. The captains flight director instrument, stall warning system, and slat disagreement systems were rendered inoperative. Power was never restored. The number 1 hydraulic system was lost at pylon separation. Hydraulic lines and follow up cables of the drive actuator for the left wing’s outboard leading edge slat were severed by the separation of the pylon and the left wing’s outboard slats retracted during climb out. The retraction of the slats caused an asymmetric stall and subsequent loss of control of the aircraft. The pylon was damaged during maintenance performed on March 29 and 30, 1979 at the American Airlines Maintenance Facility in Tulsa, Oklahoma. Engineering personnel developed procedures for removing the pylon and engine that deviated from manufacturers procedures, and did so without performing proper tests. Recommendations The NTSB recommended that the Federal Aviation Administration (FAA) issue immediately an emergency Airworthiness Directive to inspect all pylon attach points by approved inspection methods. Issue an Airworthiness Directive to require and immediate inspection of all DC-10 aircraft in which an engine pylon assembly had been removed and reinstalled for damage to the wing-mounted pylon aft bulkhead, including its forward flange and the attaching spar web and fasteners. Issue a Maintenance Alert Bulletin directing FAA maintenance inspectors to contact their assigned carriers and advise them to immediately discontinue the practice of lowering and raising the pylon with the engine still attached and adhere to recommended manufacturer procedures. Outcomes After a series of post accident inspections disclosed damaged aft bulkheads in the wing to the engine pylons, the Administrator of the FAA issued an Emergency Order of Suspension on June 6, 1979, which suspended the DC-10 series aircraft type certificate until such time as it can be ascertained that the DC-10 aircraft meets the certification criteria of Part 25 of the FAR and is eligible for a Type Certificate. Twenty days later the FAA issued Special Federal Aviation Regulation 40 which prohibited the operation of any model DC-10 aircraft within the airspace of the United States. On July 13, 1979, after a series of formal investigations, the Administrator found that the DC-10 met the requirements for issuance of a type certificate. And the Emergency Order of Suspension was terminated. In November 1979 the FAA fined American Airlines $500,000 for using faulty maintenance procedures on its DC-10 aircraft by using forklifts to mate the complete engine/pylon assembly with the wing attachment points. Continental Airlines was fined $100,000 on a similar charge. References Aviation Safety Network. Retrieved October 20, 2010, from http://aviation-safety.net/database/record.php?id=19790525-2 NTSB.

Impact of Information Technology Outsourcing

Impact of Information Technology Outsourcing Introduction Information Technology Outsourcing (ITO) will continue to have a major impact on all organizations and will over time increasingly becomes an integral part of the organizations strategy. Various aspects within the metamorphosis of ITO will be covered but not necessarily detailed. ITO has become a global phenomenon. Globalization with some distinct drivers in technology evolution has reshaped the market place and given rise to the advent of the digital age. Sustainable competitive business strategy will need to embrace this opportunity and will need to seek enablers to exploit it. IT, by virtue of the web and broadband communications in particular, allows an organization to fulfill this need. Further decrease in costs communication, increase in broadband capacity and web collaborations accelerates the process. Definitions Outsourcing has variously been defined by scholars in the Information Systems (IS) literature as follows: â€Å"The significant contribution of external suppliers in the physical and/or human resources associated with the entire or specific component of the IT infrastructure in the user organization.†(Loh and Venkataraman,1997) Outsourcing occurs when third party vendors are responsible for managing the Information Technology components on behalf of their clients. IT Outsourcing means handing over the management of some or all of an organization’s information technology (IT), systems (IS) and related services to a third party.†(Willcocks et al.,1998) †¦business practice in which a company contracts all or part of its information systems operations to one or more outside information service suppliers (Hu et al., 1997, p. 288) â€Å"Outsourcing is the handover of an activity to an external supplier. It is an alternative to internal production†(Aubert et al.,2003) â€Å"IS sourcing† is the organizational arrangement instituted for obtaining IS services and the management of resources and activities required for producing these services (Dibbern et al., 2004 , p. 11). Therefore outsourcing involves the transfer of the responsibility for carrying out an activity (previously carried on internally) to an external service provider against agreed service levels at an agreed charge. History ITO has received great attention for scholars and researchers since the mid 1990’s but it’s been around for a while as per the examples below: 1963 – Electronic Data Systems (EDS under Ross Perot) signs an agreement with Blue Cross for handling of its data processing services. Mid-1980s EDS signed contracts with Continental Airlines, First City Bank and Enron. 1989 – Kodak outsources its IS function to IBM, DEC Businessland (â€Å"Kodak Effect†) being the most notable example. More recent developments (Kern and Willcocks 2000, Ross and Westerman 2004, Kishore 2003, Kaiser 2004, Lander 2004, IBM 2004, Smith and McKeen 2004), suggests motivation is more strategic in nature with the goal of improving the business’ competitive advantage. It’s clear that ITO is not quite a new phenomenon but increasingly more prominent in this era where it is prevalent in almost every facet of business. The industry evolved from monolithic mainframe to pervasive computing. A survey of the London Stock Exchange FTSE Index over a period of three years found a generally positive relationship between high levels of outsourcing and enhanced stock market performance. Reasons for outsourcing Organizations adopt ITO for various reasons (Turban et al, 2006). The ever dynamic evolution within the IT sector grants great opportunity to business. The following reasons were invariably most common as per numerous surveys done and researched globally: Cost reduction This has been the foremost reason to outsource as senior executives’ only views the IT function as a noncore activity and a necessary cost to be minimized. Economic pressures are also external factors that lead to advent of ITO. Lacity and Willcocks(2001) explains that cost savings are no longer a major reason for outsourcing. Focus on core competency Business deems IT as a cost centre and excludes it from its core strategy. With increased shareholder demands organisations feel they need to refocus on broader business issues other than technology. Organizations places more focus on their â€Å"core competency† business (Field, 1999). Access to specialist expertise and technology Highly skilled labour comes at a cost and also the technology and is also not readily available. ITO is not only for cost savings but as a tool for utilizing state of the art expertise and technology through their service providers (Field, 1999). However of late, the companies with strong IT capabilities, such as IBM, Microsoft and SUN, are also outsourcing some of their IT functions to concentrate on their core-responsibilities and reduce costs to the economies of scale. Decision Making In the past, organizations used frameworks and models as guidelines for assessing their current state and determining future strategic actions (Gorry and Scott-Morton 1971, Nolan 1973, Luftman 1999, Venkatraman and Henderson 1993). More organizations are considering ITO as part of their strategic thinking. Organizations use ITO as a method to reduce costs, achieve efficiency and flexibility but many don’t realize the benefits due to bad decision making. ITO decision-making is a process and requires careful scrutiny before being finalized. ITO decision making process addresses a wide range of issues, such as economical (eg., financial feasibility), technological and political .This process starts with an in-house assessment of the IT capabilities which should highlight to management activities that can potentially be outsourced. SWOT (Strengths, Weaknesses, Opportunity, Threats) analysis could be used to substantiate the need whether ITO can possibly be used to negate those threats and weaknesses or whether at all necessary to explore ITO. The facts gathered should include a baseline and evaluation of the current environment which should be made available for executive management approval. Knowledge within the strategic decision at this higher level can thus be descriptive (know-what), procedural (know-how) or reasoning (know-why) (Fahey et al., 2001; Holsapple Singh, 2000). Case studies within surveys conducted by M.C.Lacity,L.P.Willcocks and D.F.Feeny published in the Sloan Management Review(Spring 1996) summarizes the ITO process. The abovementioned reasons were most common in their samples. Scope of sourcing Sourcing is often referred to in IT literature as outsourcing. The research delineates four categories of sourcing: Total outsourcing is where all IT activities including assets and management become the responsibility of a third-party vendor. Total insourcing refers to the in-house management of IT activities where external or internal staff is used with the buying in of the vendor resources to meet a temporary need. Vendor resources are only used to supplement the internally managed teams. Selective sourcing locates selected IT activities to vendors while the customer remained responsible for delivering the result and will be held accountable. De facto insourcing uses internal IT departments to provide products and services that arise from historical precedent, rather than from a reasoned evaluation of the IT service market. Considerations of sourcing Critical review of above categories found that the all-or-nothing approach ( total outsourcing) characterized by long-term(5 years or more) deals can lead to trouble after a few years as exemplified in the case studies due to: Senior Management approach ITO like any other make-or-buy decision where ubiquitous IT applications across business functions complicate matters. Lost alignment between business and IT strategies. Failed promises to access new technologies. Processing power cost depreciates at an average of 20 percent annually due the IT capabilities evolvement. And contractual costs soared greater than market prices. Termination of such contracts was found to be prohibitively expense. Research found that those who approach ITO in all-or-nothing terms either incur great risks or forego the potential benefits of selective sourcing. Reasons for ITO can be categorized as two dimensional and based on: Purchasing style refers to contracts to either be once off or an expectation of business for many years. Purchasing focus refers to companies buying resources from vendors, such as hardware,etc, and manage the delivery of IT themselves or vendors manage the IT activity and the organization expect the specified results. The result is four distinct categories will be representative of whether ITO is required as figure 1 represents. The figure also represents a decision matrix for business and guide for an effective strategy. A decision in selecting what can be outsourced usually distinguish between the contribution that IT makes to the business operations and it’s impact on competitive advantage. ITO was primarily domestic but has now evolved due to globalization and can also be categorized now by variance of service provider distance. The same reasons apply globally for ITO. On-shoring refers to the outsource vendor located in the same country of the customer. Near-shoring refers to the outsource vendor located geographically close but not in the same country. Off-shoring refers to the outsource vendor located offshore and possibly on a different continent and time-zone. Managing ITO Once the scope and type has been identified,the vendor selection process will be initiated by soliciting via Request for Proposal(RFP). Not all service providers are equal as all offer different types of services like: IS consultancies/solutions providers services in all IS functions Systems houses system integration Hardware vendors – hardware platform Ex-IS departments industry specific sourcing Development houses – develop software Generic outsourcers manage functions, especially infrastructure Freelancers There are also important criteria to look for in your service provider. Appropriate outsourcing experience and proven customer satisfaction track record. Accredited in application of best practices such as ITIL with the necessary evidence. Adequate numbers of skilled labor. Scale and geography to fulfill the organizations needs. Prepared to be flexible to you organizations needs, ie plan with current staff. Upon selection of the ITO partner, an outsourcing contract provides a legally bound, institutional framework in which each party’s rights, duties and responsibilities are codified and the goals, policies, and strategies underlying the arrangement are specified. Selective sourcing allows for flexibility within the short contracts. While some organizations realized their benefits in ITO, others have not been able to achieve benefits due to poor staffing of the IT function, poorly written service level agreements (SLA), lack of outsourcing experience on the client side, poor project management skill, poor technical infrastructure (especially in some offshore cases), and lack of trust (Jennex and Adelakum 2003, Lacity and Willcocks 2001). A contract alone is insufficient to guide outsourcing evolution and performance since it involves repeated inter-organizational exchanges that become socially embedded over time.This is why ICT outsourcing is very challenging and often a painful process!! Governance is fundamental to outsourcing relationships. Tracking SLAs and ensuring compliance to contracts are critical to controlling costs and setting minimum performance requirements. It is therefore important to ensure that the ITIL framework,starting with support management, are implemented to ensure that the IT aligns with business with the necessary metrics in place. Control Objectives for Information and Related Technology (COBIT) framework will ensure that all policies should be enforced, especially adherence to security. Critical Success Factors in an outsourcing relationship that should mitigate risk: Define a strategy with measurable goals within your SLA to ensure the relationship don’t lose momentum over time. Exercise due diligence to establish a baseline for the relationship. With the adoption of the ITIL Framework,adopt a comprehensive change management strategy. Always keep senior management involved to ensure that adherence to policies and procedures. The right metrics and regular reporting build confidence and help sustain relations. As per the Tuckman’s stage model the relationship should grow like a team and evolve in stages. Stage one is the Insourcing stage where organizations buy only a few IT functions or services from external vendors on short term contractual agreements. Only a few IT activities are bought from outside parties, generally less than 5% of the entire IT operation. Stage two is the Forming, or experimenting, stage. In this stage organizations engage in sporadic outsourcing of IT activities. Sourcing activities may be between 10-20% of the entire IT needs in the organization. Stage three is the Storming stage; it is regarded as a transition stage. At stage three organizations need to make a decision either to pursue outsourcing actively or to keep on experimenting. Stage four is the Norming stage. At this stage organization have already made a decision to pursue IT outsourcing actively and have established some norms, methods or processes for IT outsourcing within the organization. The reason for outsourcing could be either cost focus or desire to improve internal efficiency. Outsourcing could account for up to 40% of IT activities. The last stage is the strategic focus stage. In this stage IT outsourcing is part of the corporate strategy and it is not based just on cost reduction or IT improvement but is a strategic decision to use IT outsourcing within the entire organization as part of corporate strategy. Benefits from ITO Offshore outsourcing holds more advantages than disadvantages with: IT outsourcing to India helps to leverage from immensely intelligent, skilled and dedicated resources at reduced labor. Opportunity to expand service levels beyond ordinary. 24/7 Productivity has given rise to the â€Å"global delivery system† where development in particular could be done around the clock or â€Å"overnight† in a collaborative model. Choice of accredited vendors indicates that best practices are applied which should result in increase quality of service. Best-of-breed technologies accompanied by best practices should decrease the latency on time-to-market. Conclusion All factors for outsourcing was highlighted in would thus mitigate risks and highlight benefits.The future of outsourcing include service-oriented architecture (SOA), green IT, the changing role of practitioners and what the future holds for convergence of technology and business process. The ITO market would thus become more specialized and modular. Offshore ITO has also grown due to the bandwagon effect where other organizations just take advantage of the options prompted by others. Numerous surveys in outsourcing indicates that Offshore Leaders are Canada, India, Ireland, Israel, Philippines Up-and-comers are Brazil, China, Malaysia, Mexico, Russia, South Africa. Rookies are Argentina, Chile, Costa Rica, New Zealand, Thailand, Ukraine Reverse sourcing is a new trend in global business where offshore outsourcing is reversed to near-shore outsourcing but not primarily for cost factors. This trend is more evident in call-centers as customers prefer dealing with agents proficient in their language and culture. References Apte, U. M., Sobol, M.

Benefits And Challenges Of Department Stores

Benefits And Challenges Of Department Stores Department stores represent a large retail organization which offers to consumers a large choice of goods and services. Consumers have the opportunity to compare price, quality, and service at different stores at the same time and in a limited place. So the company can profit from individual benefits other sectors. The strategy of F4U is not only to sell quality goods at a reasonable price , but also to offer a unique service .Its prices are neither as cheap as the lower end department store, nor as expensive as the high-end store. F4U will try to bring the immediate attention of consumer through visual effects like layout, displays and colored posters and will place itself directly in front of the shoppers. The company wants, thereby, to entice different target groups and gain those other brands according to the motto good quality, fashion style, best price. In addition F4U intend to retain its consumer through a bonus program and to collect their personal data to build an aggregate profile of individual consumers to target them with special offers and appropriate advertisements. Benefits and challenges of Department stores: Department stores offer to the customer the direct experience to touch and feel the product and judge its quality as well as the possibility of living the purchase as experience (Steinmann 2011:27) .The customer can try the clothes and take them immediately. Whereby the number of returns can be decreased. The face-to-face contact is crucial for many consumers especially for old people or people who dislike shopping online. Another advantage is the longer opening hours compared to specialty retail stores especially on Friday and Saturday. Department stores have also many disadvantages such as the existing of a concrete and inflexible location. Consequently, the location is a crucial factor for the shopping place. In this context, many consumers opine that, the fixed opening hours and parking fees are unfavorable. In addition, the time exposure, due to the travelling time, could be also a problem for some consumers (Heinemann 2008:19) Furthermore, department stores emerge several costs for the company such as lease costs and staff costs. Catalog selling Catalog selling as a channel for F4U Catalog selling is one of the most popular strategies used in Fashion game. The approach involves the creation of a printed catalog with a listing of products for sale. Every product is explicitly described and clearly illustrated with a picture to make the shopping experience as real as possible for the consumer. The catalog contains also a size chart to help consumer choosing the appropriate size. F4U tries, across catalog selling, to expand its clientele and above all to attain consumers, who are not familiar with using the internet or who dislike to walk around the stores for buying clothes. The catalog will comprise different ordering informations. The consumer can choose between ordering by telephone and entering the order at the online site.F4u will also offer its consumers various delivery options .They range from shipment directly to the consumers address, to delivering the goods to a F4u retail store or simply to a Packstation. Benefits and challenges of catalog selling: The catalog shopping approach allows customers to shop comfortable without time pressure .It gives the company the possibility to reach various consumer groups. That may also increase the exposure of retailers to potential clients. The catalog represents essentially the showroom. According to Geller (2002, 148) Response: The Complete Guide to Profitable Direct Marketing if the catalog is the store, the written copy is the salesperson. Instead of waiting for the consumer, the company takes the initiative in presenting its products. Because payment is received in advance, retailers may not need to stock the merchandise and tie up their cash flow. The main disadvantage of catalog order is the difficulty to build trust and customer loyalty. In addition consumer must wait a period of time to get their order. An additional vulnerability is the long lead times. Selling via catalogs could be very expensive because a catalog must be extremely well written and designed to move the shopping desire by consumers. Low response rates and high postal costs may make catalog selling to an unfavorable channel. Electronic commerce Electronic commerce as a channel for F4U Electronic commerce or online shopping is the most effective way to brand your product line or services and to increase your visibility on line. It follows that a properly marketed and visible online business will experience a growth of shoppers and a higher conversion rate (Inci, 2010) .Through a user-friendly and well designed website F4U will become a global presence. The company will also use several tools to raise the visibility of the website and the number of its visitors. This will allow the company to reach new target groups and markets. Like by the catalog selling, the consumer will have to choose between different payment and delivery options. The client can check a product in-store or online, see which stores currently have an item in stock, or verify its availability at a specific store. The Online shop will make it possible for consumers to shop 24 hours a day, 7 days a week. Benefits and challenges of electronic commerce: Electronic commerce combines a variety of benefits. It allows reaching consumers without a geographic limitation. By these means the size of the market will expand from regional area to the national one or peradventure from national to international. In addition the company can always change the listed prices for several or edit the website in just a few clicks. Using the online selling can reduce many costs like logistical problems, the costs of distribution, of processing or of storing informations. By contrast, the company can increase the quality of services. Furthermore e-commerce makes it possible to generate consumer data and to evolve an individualized consumer profile Electronic commerce has many advantages but also disadvantages. According to Rajarman (2010:11) an important disadvantage is that Many persons go shopping for social contacts, touch and feel and bargaining before buying items. E-commerce will de-personalize transactions. . Other persons are afraid of hackers and avoid giving their credit card numbers. Sometimes the item description is not enough for a decision to buy them because many items need to be felt and touched. Rajarman (2010:12) mentions also that online-business expose the catalogues and prices to competitors. The advantage of secrecy of traditional mode of doing business is lost References Heinemann, G., 2008.

Dance brazil :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Dance Brazil Dance Brazil performs with flexibility and power, which is evident throughout its entirety. Whether the company is lying on the floor or leaping through the air, they command their space. However, throughout the production they also incorporate one important factor, their culture. In the introduction of the show, the dancers demonstrate their religious ways by presenting the sign of the cross to the people. Throughout the scene, the costumes that were being worn were all directly related to the colors of various gods. Throughout one scene, the dancers become possessed, one man loses control of his emotions, and lands into another man’s arms. One could possible interpret that this man is landing into the arms of god. The following scene featured a woman dressed in blue. I appreciated the way their movements resembled water that recedes after the tide; movements that matched the full and vibrant sound of the band. I also valued the bleak positioning, woman facing forward, man facing away, with their backs against each other. The man repeatedly placed his hand on the woman, only to have her definitively push him away. This control at the beginning contrasted with a kind of compliance at the end, as the woman was carried off on the back of the man. The music pulled their bodies. They were elegant yet powerful at the same time. They had a superior blend of a partnership ,they danced like a partnership without it being a partnership dance.   Ã‚  Ã‚  Ã‚  Ã‚  Overall, I took pleasure in the production â€Å"Dance Brazil†. My first thoughts were negative, I did not expect this dance to be as exciting and interesting as it truly was.

Albert Einstein Essays -- Essay s Papers

Albert Einstein Einstein was born on March 14, 1879, in Ulm Germany. He lived there with his parents, Herman and Pauline. After a year in Ulm, due to the failure of his father's electrical and engineering workshop, the Einstein family moved to Munich (the capital of Bavaria), where after a year in residence there, Einstein's mother had Maja, Einstein's sister. Despite the fact that he was Jewish, from age five until age ten, Einstein attended a Catholic School near his home. But, at age 10, Einstein was transferred to the "Luitpold Gymnasium," where Latin, Greek, History, and Geography were pounded into childrens' heads. His parents wanted him to finish school, get his diploma so he could go to a University, and then become an electrical engineer. But Einstein had other Ideas for his future. Einstein's father wanted him to attend a university but he could not because he did not have a diploma from the Gymnasium. But there was a solution to this problem over the Alps, in Zurich, there was The Swiss F ederal Institute of Technology which did not require a diploma to attend. The one thing it did require was the applicant to pass an entrance exam. But then yet another problem arose, most scholars were 18 when they entered the institute, and Einstein was only 16. Einstein took the risk, and in the autumn he was dispatched over the Alps. Einstein took the exam, but did not pass.

Advertising and People of Color Essay

In their article â€Å"Advertising and People of Color,† Clint Wilson and Felix Gutierrez talk about stereotypes being portrayed in the media, even today. A good example of this is of the Aunt Jemima pancake mix. Then, the company featured a stereotypical, heavy, loud black woman (mammy) advertising the pancake mix. Some of the advertising was more neutralized; for example, Rastus is shown serving both black and white children breakfast (284). Another issue Wilson and Gutierrez talks about is the courtship of blacks and Latinos in advertising. From the civil rights movement, advertisers specifically targeted minorities, specifically blacks and Latinos for products such as liquor and cigarettes, but also advertised to minorities in culturally related advertisements. Articles such as â€Å"America’s Spanish Treasure† and books such as The $30 Billion Negro were written for advertisers to show how important it was to reach minorities to make more money. Overall, I don’t think the media has made much of a difference. I watched tv for a couple hours today to see if there were any advertisements directed toward minorities or that used minorities. My conclusion: not many. I didn’t see any that specifically were directed toward minorities and the ones that did portray minorities was a house cleaning commercial. The black lady was doing what every other middle class housewife does-clean all day (note sarcastic tone here). She was using a cleaning product while the announcer said his piece. Other than that, there was not anything (this was Fox 12, between 10 AM and 12 PM and I did do other homework while watching, lol).

Joyce Carol Oates “Golden Gloves” Story

Yu-Tzu Lin Instructor Emily Plicka English 101 6, October 2012 In Joyce Carol Oates’ story â€Å"Golden Gloves†, it is about the growth of a boy to becoming a man. This boy who was a born with deformed feet, he had couldn’t walk until 3 years old. His dad was a little shameful of him being handicapped. He didn’t like people to touch him or help him. When he was eight, he had a surgery on his feet. He suffered a lot of pains during his rehabilitation . His father took him to a boxing match and he fell in love with boxing right away.He told himself that He would box one day at the Golden Gloves tournament and people would see him standing there in that ring, not in a wheelchair. He began his training at the YMCA. He worked out every day in order to keep himself in the best shape. All he thought about was boxing. He was told that he had talent and had a future. He won many local matches. At the young age of eighteen he boxed in the semi-finals of the Golden G loves tournament, and it was the game that ended his boxing career. A few years later, he married a woman, Annemarie, who desired to have children so bad.She always wanted to have a family even after her first miscarriage; she still persisted to be pregnant again. Finally, Annemarie got pregnant again. They took natural childbirth classes together. But her husband never told Annemarie about his past—about his amateur boxing. He even wasn’t honest about his premature birth and deformed feet. It is a deep shame he struggles with. Joyce Carol Oates â€Å"Golden Gloves† story, the main character struggles with insecurity, even as an adult who eventually achieves success and happiness in his career and marriage.His insecurity haunts him his whole life through: First, insecurity as a child, he was suffering a lot of pain from his deformed feet. He was being bullied by the kids at school. He would grab them and hurt them and made them cry when he got older. Those child hood experiences built up his personality more like shy, showing none of his emotions in him, even a little bit self-abased. As a child, there was not much things that he could do about it, so he keeps his hurt and anger bottled up inside. (P. 774) Second, as a boxer, he lies awake at night worrying about the â€Å"punch out of nowhere† and worries about disappointing his dad.When he was training at YMCA, he was constantly thinking about what did other people think about him and if he challenged other boys, could he knock him out? He also practiced with boys that might be older than him. He improved himself, he knew his weaknesses. (p776) From that example shows that he was insecure that he would be fail. Although some readers might think that it showed his humility, actually here is a mixture feeling of being humble and afraid of not being the best boxer. His father made the statement: â€Å"Either you have the talent or you don’t, It can’t be fake. (p. 776) t his pointed out that he had to win to show that he had talent in boxing. Also his dad put bets on him and that gave him more pressure and worried about letting his dad down. That is probably why he would wake up in the middle of the night and confused about himself. Here, Oates wrote â€Å"His fists when he woke would be clenched so hard his fingernails would be cutting into his palms, his toes curled in tight and cramped as if still deformed, secretly deformed. † (p. 779) because character here was physically healed, he was not crippled anymore.But he still had the same reaction as when he was crippled before. Moreover, the last word, â€Å"secretly deformed†, makes readers feel like that he is still deformed in some way. Maybe he is not physically deformed; maybe in deep down his heart, he is still that crippled boy. Third, he was also insecure as an adult in his strength —admire the strength of his wife, her willingness to try again reminds him of his failure at eighteen, and his insecurity haunts him. Annemarie, his wife, was miscarriage the first pregnancy. She suffered a lot physically and mentally.Annemarie was persistent to be pregnant again but he hesitated. Annemarie’s persistence made him think of his boxing career, made him think of his failure. The main character told himself that â€Å"It’s just physical after all it doesn’t mean anything. Such failures of physical life don’t mean anything. You take the blow then get on with living isn’t that the history of the world? Of course it is. † This part showed that he was trying to comfort himself and made himself feel better about trying again. And the next he said he is an adult now, not a boy any longer. (p. 82) He compared Annemarie’s miscarriage to his failure at eighteen, and he admired the strength of his wife and persuaded himself that he can take more now. Even though when the baby due in less than a week, he was still insecu re about the punch out of nowhere. (p. 783) Maybe he was worried about that he couldn’t control what would happen next. Throughout his life, things were always happened unexpectedly. â€Å"He hadn’t been a fighter at all, merely a victim. † (P. 783) This phrase from Oate’s story pointed out that his biggest insecurity is from life, since he was a premature baby who had deformed feet.He worked so hard to be able to walk; he got bullied by other kids. When he finally became a boxer, he was worried about disappointing his dad, and failure in boxing. He still struggled with insecurity about things happened to his wife. Actually he had a good life when he grew up. But why does he continue to feel insecure in his life, in his happiness? Is it because deep down inside of him he is still that little boy with deformed feet that people pitted or made fun of? Hopefully, he would learn from strength of Annemarie.

CHAPTER I INTRODUCTION 1. 1 Background Food is one of human sources of calorie, protein, fats, and nutrition. Yet, because of the highly nutritious content, food is susceptible to growth of microorganisms. By the presence of microorganisms in food, the food is more likely to have shorter shelf life. Thus, mostly it is resolved by the addition of antimicrobial substances to food, such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms or even destroyed them, as they have antimicrobial agents.Some examples of condiments and preservatives are ginger, clove, sodium benzoate, garlic, and coriander. The factors contributing in the effectiveness of condiments and preservatives in inhibiting the growth of microorganisms are the concentration of the antimicrobial, temperature, characteristic of the microorganisms and food, storage time. As different types of microorganisms have different resistance toward the antimicrobial substance, it is important to understand the characteristic of the microorganisms towards the antimicrobial agent.There are two types of resistance: intrinsic resistance and acquired resistance. There are some methods of observing the capability of the condiments in inhibiting the growth of microorganisms. In the experiment, the method used is well diffusion method, which used different type of condiments and added into holes of agar, where by the inhibition zone by the condiments could be observed. The larger the inhibition zone, the more effective the condiment was in inhibiting the growth of microorganisms. 1. 2 Objectives By conducting the experiment, students are expected to learn and observe he effectiveness of antimicrobial substance consisted in condiments and potassium sorbate towards the growth of microorganisms. CHAPTER II LITERATURE REVIEW 2. 1 Antimicrobials Referring to Volk and Wheeler (1993), antimicrobials are the substances that are used to inhibit or kill pathogenic or non-pathog enic microbes. Antimicrobials are also often used as sanitizers and preservatives. Sanitizer is an agent to decrease the amount of microorganisms to the acceptable level. It is generally used in food processing equipments. Antimicrobials are grouped into natural antimicrobials and chemical antimicrobials.According to Fardiaz (1992), antimicrobials may be microstatic, which is inhibitory to the growth of microbes, and microcidal, which means able to kill microbes. Fruit extract is one most susceptible food materials and thus, is often added with preservatives, especially chemical preservatives, stored at low temperature, or pasteurized. Pasteurization is a heating process at 63? C for thirty minutes. This process is aimed to preserve the stability of the food materials (Buckle et al. , 1987). The growth of microbes can be controlled by using various methods, namely physical method, chemical method, and immunological method.The control of microorganism growth is performed to kill the microbes, to inhibit the microbes, and to destroy the microbes. Physical controls can be performed by sterilization with heating or radiation and filtering. Chemical controls can be carried out by using chemical antimicrobial compounds, such as disinfectants and preservatives. Whereas immunological controls can be performed by vaccination (Batzing, 2002). 2. 2 Active Antimicrobial Compounds in Spices 2. 2. 1 Garlic Garlic come from the onion family and are an erect biennial herb, which grow annually. It has irregular roots, condensed, flattened step and narrow and has lat leaves. Garlic’s bulb consists of 6 to 35 bulblets called cloves which enclosed in a thick whitish, glistening, and transparent covering (Anonym1, 2000). According to Ankri and Mirelman (1999), garlic or Allium sativum or lahsoon in Indian name is an edible plant, which has been generating a lot of interest as a medicinal panacea and a cure for a wide variety of different conditions since the human history h as begun. It is reported to have anticancer effects and to reduce blood lipids in human body. Figure 2. 1 shows the approximate composition of fresh garlic. Figure 2. The approximate composition of fresh garlic Source: Ahmad (1996) The active compound found in garlic cloves which have an unusual concentration of sulfur-containing compounds (1-3%) is called allicin. It is a volatile molecule, which is poorly miscible in aqueous solution, and has a strong typical odor of crushed garlic. Chemically, allicin can be synthesized by mild oxidation of diallyl disulfide as presented in Figure 2. 1. It is to be noticed in Figure 2. 2 that there is a compound called alliin which is a stable precusor, that later will be converted to allicin by enzyme called alliinase present in cloves too.Moreover, alliinase is surprisingly found in large amounts in cloves, which is about 10% of the total protein content. Practically, allicin is produced when garlic cloves are cut into or crushed (Ankri and Mir elman, 1999) Figure 2. 2 Generation of allicin in a garlic clove Source: Ankri and Mirelman (1999) According to Ankri and Mirelman (1999), there are several biological activities in allicin such as its activity as an antioxidant and its ability to attack the sulphur (SH) groups in enzymes and proteins while modifying their activities as well.Furthermore, allicin can rapidly penetrate into cells through the cell membranes. In its pure form, allicin has been reputed to exhibit antibacterial activity against a wide range of Gram-negative and Gram-positive bacteria, for instance Escherichia coli that is known to be a multidrug-resistant enterotoxicogenic strains, Salmonella, Staphylococcus, Streptococcus, Klebsiella, Proteus, Bacillus, and Clostridium. It also has antifungal activity that prevents the formation of mycotoxins such as the aflatoxin of Aspergillus parasiticus.Allicin has shown the anticandida activity towards and is effective against the group species of Candida, Cryptococ cus, Trichophyton, Epidermophyton, and Microsporum at only low concentration since it inhibits both the germination of spores and the formation of hyphae. Referring to Dobre et al. (2011), allicin can also attack Aspergillus, Fusarium, and Penecillium species, which are responsible for food poisoning and food decay.The main mechanism of the antimicrobial activity in allicin is the inhibition of certain thiol-containing enzymes in the microorganisms by the super fast reaction of thiosulfinates with thiol groups, such as alcohol dehydrogenase, thioredoxin reductase, and RNA polymerase that later will affect the essential metabolism of cysteine proteinase activity. The reason why microbial cells are highly sensitive to allicin is probably because the lack of glutathione (thiol molecules such as trypanothione) which results of lack of the ability to reactivate the pivotal SH-enzymes that are thiolated by allicin (Ankri and Mirelman, 1999). . 2. 2 Coriander Coriander or Coriandrum sativu m L. is originated from the Mediterranean region and has the appearance of flat shape in the one side while slightly pointed shape is found in the other side. Coriander seed has various lengths between 3 to 5 mm with brown color in ripe state (Sarkar, 2012). Accodring to Rattanachaikunsopon and Phumkhachorn (2010), it has been traditionally used as an analgesic, aphrodisiac, antirheumatic, anti-inflammatory, diuretic, antispasmodic, circulatory stimulant, and antidiabetic. Beside that, coriander is known to have effect in lowering cholesterol. Table 2. shows the composition of coriander seed. Table 2. 3 The coriander seed composition in 1 tsp Total Fat 0. 9g 1% Saturated Fat 0. 00g 0% Monounsaturated Fat 0. 7g Polyunsaturated Fat 0. 1g Cholesterol 0mg 0% Sodium 2mg 0% Total Carbohydrates 2. 7g 1% Dietary Fiber 2. 1 g 8% Protein 0. 6g Vitamin A 0% Vitamin C 2% Calcium 4% Iron 5% Source: Sarkar (2012) The precise volatile compounds acting as antimicrobial compounds have not been exami ned clearly till now, although there are some volatile compounds suggested to be the antimicrobial compound inside coriander which are (2E) – hexenal and (3E) – hexenal (Kubo et al. , 2004).They are reported to have antimicrobial activity against Gram-negative and Gram-positive bacteria such as Escherichia coli O157:H7, Listeria monocytogenes, and Staphylococcus aureus, which are foodborne pathogenic bacteria. It also exhibits bactericidal activity and is reported to have an effective antibacterial. The mechanism of the activity of coriander is membrane damage causing cell death to the bacteria (Silva et al. , 2011). However, according to Uma et al. (2009), coriander seems to not having an effective antifungal activity and its activity toward yeast have not yet been examined further. 2. 2. 3 Black PepperBlack pepper (Pipper nigrum) is a condiment that has been used since ancient times and is native to India. Black pepper is useful for treatment of various sicknesses su ch as vertigo, asthma, fever and also cholera. The volatile oil of black pepper has been shown to have antimicrobial activity as well (Karsha and Lakshmi, 2009). The major antimicrobial compund found in black pepper are monoterpenes and sesquiterpenes (Davidson et al. , 2005). According to Karsha and Lakshmi (2009), black pepper shows strong antimicrobial activity against gram-positive bacteria such as Staphylococcus aureus, Bacillus cereus and Streptococcus faecalis.Gram-negative bacteria such as Pseudomonas aeruginosa, Salmonella typhi and Escherichia coli are affected as well, although the effect on gram-positive bacteria is better. The mechanism of the antimicrobial activity appears to be loss of control over cell membrane permeability. According to Singh et al. (2004), black pepper has antifungal activity as well as it is effective in stopping the growth of molds such as Fusarium graminearum. Black pepper is also shown to be able to inhibit the growth of yeast such as Candida a lbicans (Joe et al. , 2009). 2. 2. 4 Potassium SorbatePotassium sorbate are currently one of the most widely used preservative and can be used to preserve foods, animal feeds, pharmaceuticals, and cosmetics. Potassium sorbate may be manufactured as a powder or granules and has an antimicrobial potency of 74% compared to sorbic acid. The molecular weight of potassium sorbate is 150. 22 and is the most soluble form of sorbate compared to the others, such as calcium sorbate and sodium sorbate. Besides good solubility, potassium sorbate is also has good stability and easy to manufacture, making it the most used form of sorbate in food industry.Sorbate is very effective when used against bacteria, molds, and yeasts. Yeasts inhibited by sorbate are Brettanomyces, Candida, Cryptococccus, Debaryomyces, Endomycopsis, Hansenula, Kloeckera, Pichia, Rhodotorula, Saccharomyces, Sporobolomyces, Torulaspora, Torulopsis, and Zygosaccharomyces. Molds species inhibited by sorbate are Alternaria, Asco chyta, Ascosphaera, Aspergillus, Botrytis, Cephalosporium, Chaetomium, Cladosporium, Colletotrichum, Cunninghamella, Curvularia, Fusarium, Geotrichum, Gliocladium, Helminthosporium,Heterosporium, Humicola, Monilia, Mucor, Penicillium, Phoma, Pepularia, Pestalotiopsis, Pullularia, Rhizoctonia, Rhizopus, Rosellinia, Sporotrichum, Trichoderma, Truncatella, Ulocladium, and others. While for bacteria, the species inhibited are Acetobacter, Achromobacter, Acinetobacter, Enterobacter, Aeromonas, Alcaligenes, Alteromonas, Arthrobacter, Bacillus, Campylobacter, Clostridium, Escherichia, Klebsiella, Lactobacillus, Micrococcus, Moraxella, Mycobacterium, Pediococcus, Proteus, Pseudomonas, Salmonella, Serratia, Staphylococcus, Vibrio, Yersinia, and others (Davidson et al. , 2005). 2. 3Mechanism of Antimicrobials There exist some mechanisms of antimicrobial activity in inhibiting the growth of microbes. The antimicrobials are classified into: cell wall destructor, cell wall permeability intervent ion, destructor of proteins, nucleic acids, and enzymes, antimetabolites, inhibitors of nucleic acid synthesis, and cell plasmolysis (Fardiaz and Betty, 1989). Referring to Fardiaz and Betty (1989), the broken cell wall of microorganisms will cause the cell content to depart from the cell and thus, inhibit the cell metabolisms. Severe destructions on the cell may cause the death of the cell.Lysozyme is one of the enzymes that are able to destruct the cell wall of Gram-positive bacteria. An enzyme produced by a bacterium might be able to inhibit the growth of other microbes. There is also a type of antimicrobials that is able to inhibit the formation of cell wall materials. These cells that do not have cell wall are called protoplast. Protoplast is very easily broken, except when placed in isotonic medium. Penicillin and cycloserin are examples of compounds that retard the formation of peptidoglycan in developing cell. Gram-positive bacteria are susceptible to penicillin as they have lots of peptidoglycans.The breaking of plasma membrane and leakage of cell content will inhibit the microorganism growth or even kill the microorganisms. The implication if the cell destruction is the enzymes will not be able to function properly in the cell metabolism. However, antimicrobials that intervene the cell wall permeability are rarely used in food industries (Fardiaz and Betty, 1989). Compounds destructing the protein and nucleic acid are able to destroy cells. This type of destruction is unfixable. For instance, certain amount of alcohol and sodium chloride are able to denaturate the proteins.Those two compounds are often used in food industries (Fardiaz and Betty, 1989). Antimetabolites are the compounds that are similar to natural metabolites. These antimetabolites will interrupt the metabolisms in the cell. The interruption of the metabolisms might retard the cell growth or even kill the cell. Furthermore, the synthesis of DNA and RNA may be inhibited by some antimic robial compounds, namely the compounds that are able to retard the formation of nucleic acid arrangement and compounds that inhibit the nucleic acid polymerization (Fardiaz and Betty, 1989).Plasmolysis or the breakage of a cell is caused by the high plasmolysis pressure. Materials that are often used in food to promote the cell plasmolysis are salt and sugar. Salt and sugar are considered to be able to increase the osmotic pressure in food materials therefore plasmolysis takes place (Fardiaz and Betty, 1989). 2. 4 Antimicrobial Sensitivity towards Microbial Defense Microorganisms have the ability to resist some types of antimicrobial substances. There are two types of resistance in microorganisms toward antimicrobial agents, such as intrinsic or natural resistance and acquired resistance.The antimicrobial agents in intrinsic resistance could not affect the microorganisms, as they have no target sites, which are the microorganisms, to affect. In contrary, in microorganisms that donâ €™t have the intrinsic resistance, the antimicrobial substance could gradually enter the microbial cell and affecting the activity of the microorganisms, as the microorganisms’ cell membrane have lower permeability to antimicrobial substance (Sosa et al. , 2010). Furthermore, in acquired resistance, the microorganisms are naturally vulnerable, as they need specific ways for preventing to be affected by the antimicrobial substances.Some examples of the specific ways are the presence of enzyme that has the ability to inactivate the antimicrobial agent, or alternative enzyme that has the ability to inhibit the activity of antimicrobial agent. Then, it also happens when there is mutation and post-transcriptional and posttranslational in the microorganisms that are the target of the antimicrobial agent. Thus, these will reduce the binding of the antimicrobial agent (Sosa et al. , 2010). Every microorganism has different sensitivity towards different type antimicrobial agents. Coriander (Coriandrum sativum L. is mostly used as seasoning condiment. According to Kubo et al. (2004), in the leaves of coriander, there are volatile oils that are suggested to have antimicrobial properties against food born pathogen, such as Salmonella species, which are gram-negative bacteria. Black pepper (Piper nigrum L. ) is used mostly in food as seasoning condiments. The aqueous and ethanolic extract of black pepper is very effective for inhibiting antibacterial activity agains penicillin G resistant strain of Staphylococcus aureus, Bacillus cereus and Bacillus subtilis (Chaudhry and Tariq, 2006).According to Karsha and Lakshmi (2010) experiment, gram-positive bacteria were more susceptible towards antimicrobial in black pepper than gramnegative bacteria. In gram-positive bacteria, the most susceptible towards antimicrobial in black pepper is Staphylococcus and followed by Bacillus and Streptococcus. Furthermore, among gram-negative bacteria, the most susceptible towards an timicrobial in black pepper is Pseudomonas, followed by E. coli, Klebsiella and Salmonella. Garlic (Allium sativum) is commonly used for antifungal, antiviral, antibacterial, antihelmantic, antiseptic and anti-infamatory.Garlic extract is effevtive in inhibiting the microbial activity of both gram-positive and gramnegative bacteria. Several examples of the gram-negative bacteria are E. coli, Salmonella species and Citrobacter Enterobacter, Pseudomon, Kilabsella) and the gram-positive bacteria are Pseudomonas aeruginosa, Salmonella typhi, Proteus, spp. , Staphylococcus aureus, S. pneumonia Group A streptococcus and Bacillus anthrax (Daka, 2011; Durairaj, 2009). Potassium sorbate is used as preservative in food as the sorbic acid is more effective than benzoic acid in preserving food. The preservation process occurs in higher pH.It is effective to inhibit the microbial activity of Pseudomonas species, which are categorized as gram-positive bacteria (Beuchat, 1980). Mostly, gram-positi ve bacteria are more sensitive towards antimicrobial agent than gram-negative bacteria (Torrence and Isaacson, 2003). 2. 5 Factors Affecting Microorganism Strength towards Antimicrobial Compounds The resistance of microbes towards particular antimicrobial compound is dependent on several factors that contained in that particular microbe such as the cell wall, protein content, nucleic acid, and membrane cell (Lay, 2002).There are several types of microbes that have cell walls, and an antimicrobial compound that can affect the mechanism of the cell wall that influence the microbial resistance. Anti-microbial compounds may interfere with the work of the cell wall as well as peptidoglycan biosynthesis, which is the process in prokaryotic cell wall structure construction. Disruption of peptidoglycan may affect the resistance and sensitivity of microbes to changes in osmotic perspective (Lay, 2002). Microbes also contain nucleic acids.The nucleic acid can be affected by antimicrobial comp unds where the enzymes that are going to be used for the synthesis of nucleic acid are inhibited. The example is rifampin where it binds the enzyme RNA polymerase, quinolone as well as binding enzyme DNA gyrase (Lay, 2002). The resistance of microbes can be affected by the metabolism of the microbes. Enzyme that catalyzes the synthesis of essential molecules can be inhibited by antimetabolite. Antimetabolite is the antimicrobial that is used for inhibiting the growth of microbes. An example of antimetabolite is the sulfinylamide (Lay, 2002).In general, most living cells including microorganisms has the ability to control what is going in and out of the membrane. If there is a rupture in the membrane, it will cause the spillage of the essential inorganic ions. Thus, rupture in the cell membrane can affect the growth and death of the microbes (Lay, 2002). 2. 6 Methods of Microbial Defense towards Antimicrobial Activity 2. 6. 1 Well Diffusion Method Well diffusion method is done by pou ring the microbial suspension that is going to be tested into a sterile Petri dish continued by pouring the media agar into the dish. Then, the Petri dishes are mixed by the eight movement ethod to allow even mixing. The media is then allowed to be solidified and cynlidrical holes are made. The holes are then filled with antimicrobial agents to be tested. The cup was incubated at 37Â °C for two days and then observed on the antimicrobial activity of the tested microbial suspension. Antimicrobial ingredients poured into the well are able to spread evenly as it can diffuse in all directions around the microbial suspension. Once incubated, usually will form a clean circular zone of microbes. This method can be used to test several different types of antimicrobial agents. (Smith, 2005) 2. 6. Kirby Bauer Disc Method One of the easy methods to test the vulnerability of organisms towards the antimicrobial agents is by inoculating the agar with culture and allowing the antimicrobes to diff use to the media agar. The discs that contain antimicrobial agents are placed on the surface of the plate that has the organisms that are going to be tested. At particular distance on respective discs, the antimicrobes will diffuse to a point where the antimicrobes are unable to inhibit the microbial growth. Antimicrobial effectiveness is shown by the inhibition zones. Inhibition zone appears as clean areas that surround the disc.The diameter zone can be measured by using ruler and the result of the experiment considered to be one antibiogram. (Smith, 2005) 2. 6. 3 MIC and MBC The antimicrobial activity can be observed by knowing the concentration of the antimicrobial agents that are going to be used by reducing the total critical number of bacteria that caused their death. MIC (minimum inhibitor concentration) from an antimicrobes can be known by providing the antimicrobial agents into two serial dilutions in series tubes or can be done by well method in a media that has been inocu lated with bacteria.Series tubes that have been filled with antimicrobial agents are incubated to see the growth of the bacteria and the turbidity is observed. The increment in turbidity indicates the growth of the microbes. MIC is the lowest concentration of an antimicrobial agent where the grwoth can be inhibited completely. (Smith, 2005) MBC (minimum bactericidal concentration) is the total number of antimicrobial agents that is required to kill organisms.MBC is done by taking a part from each serial tubes from the MIC that does not show any growth of the bacteria that has been incubated, The samples is taken from respective tubes that has been incubated in pour plate media. MBC is the lowest concentration of antimicrobial agents that are able to kill at least 99. 9% of the inoculums that has been incubated (Smith, 2005). 2. 7 Food Preservatives Preservatives are commonly used to prevent destruction of physical, chemical and microbiological food. Use of antimicrobial preservative s combined with other preservatives so that the preservation of the food will be maximized.According Fellows (2000), the criteria for antimicrobial preservative in food are the usage and is more efficient which when dissolved in water, stable in storage, non-toxic, low antimicrobial concentrations but has a wide range, optimum efficiency at room temperature, non-corrosive, odorless, and its high penetrative ability to the food. Based on its mechanism, the antimicrobial agent acts as the rupture of the cell wall When there is a rupture on the cell wall, the cell contents will spill out thus inhibiting the metabolism of cells. The destruction of the cell wall can result in cell death.Lysozyme can damage the cell walls of Gram-positive bacteria. Penicillin and sikloserin inhibit the growth of peptidoglycan in the cell develops. Gram-positive bacteria is sensitive towards penicillin as the high level of peptidoglycan content. Damage to the cell wall would also cause damage to the plasma membrane (Fellows, 2000). NaCl and alcohol is often used to preserve food because it can cause denaturation of proteins and nucleic acids that can destroy the cell and cannot be repaired. While H2O2 is an antimicrobial that can destroy the enzyme activity of microbes.Compounds inhibiting the formation of nucleic acids and nucleic acid polymerization inhibitor compounds can inhibit the synthesis of both DNA and RNA. The use of salt and sugar can cause plasmolysis the microbial cell. Since the osmotic pressure on microbial too high, so that the cells undergo plasmolisis and can inhibit the growth of microbes (Fellows, 2000). Ascorbic acid can inhibit the growth of bacteria and molds in a way to inactivate the enzyme fatty acid dehydrogenase. Ascorbic acid can work optimally at a pH above 6. 5.Propionic acid is at its most effectiveness to inhibit molds and yeasts with maximal activity at pH above 5. Acetic acid as vinegar used to preserve bread in order to prevent mold contamination, but vinegar cannot inhibit the growth of yeasts. Acetic acid work optimally at low pH (acid). Ethylene oxide and propylene oxide can be used as a fumigant in spices and flour. Sodium or potassium nitrite and nitrate are commonly used for preservatives in meat products. Maximum working power of nitrite compounds is pH of about 57. Nitrite also serves to inhibit Clostridium botulinum, Acinetobacter, Moraxella, Flavobacterium,Pseudomonas, Enterobacter, Escherichia, and some micrococcus. Nitrites are heated simultaneously with foods will provide the growth inhibitory effect against microbes ten times greater than that of nitrite without heating (Fellows, 2000). CHAPTER III MATERIALS AND METHOD 3. 1 Materials and Equipments Equipments that are used in the experiment are balance, blender, grater, dilution bottle, autoclave, waterbath, refrigerator, vernier caliper, tip with the cuttop, sterile toothpicks, sterile petri dishes, micropipette, tip (10 ml and 100Â µl), and Bunsen’s b urner.Materials that are used are spices (black pepper, garlic, and coriander), potassium sorbate, alcohol, aquadest, bacteria culture (Bacillus subtilis), yeast culture (Candida tropicalis), mold culture (Aspergillus oryzae), PCA media, and NA media. 3. 2 Procedures 3. 2. 1 Extract Preparation 1. Spices were weighed up to 3 grams and reduced in size. 2. The spices were mixed with 10mL of ethanol into Erlenmeyer flasks. 3. 2. 2 Antimicrobial Assay 1. 1mL of culture is added into Petri plate 2. The matching medium is added into the Petri plates (NA for B. subtilis and PDA for A. ryzae and C. tropicalis) 3. The media were let to solidify. 4. Holes were made by using tips with cut-tops. 5. Mixtures of spices were added into the holes. 6. The plates were incubated were incubated for 48 hours in 37? C. CHAPTER IV RESULTS AND DISSCUSION 4. 1 Effect of Antimicrobial Compounds Towards Microbial Growth 4. 1. 1 Garlic Table 4. 1 Observation result of inhibitory activity by garlic From Table 4 . 1, it can be seen that the microorganism that was the most susceptible to allicin contained in garlic, judging by the largest area inhibition, was Bacillus subtilis.There were even no growths in some Petri dishes that meant that the effectiveness of allicin as the antimicrobial compound could be found most when it was applied for bacteria, which was Bacillus subtilis in particular. It matched with the previous literature discussed stating that allicin is an active compound in garlic that attacks the cell membrane in microorganism. However, there was an error found in the experiment from Group 4, which resulted in no inhibition found from Bacillus subtilis. This might happen due to the absence of the allicin itself or the ontamination happened which might result in the building of the resistance towards antimicrobial compound. Afterwards, it can be seen from the experiment that Candida tropicalis and Aspergillus oryzae shared almost the same result, which means that they were also susceptible to allicin. The uneven inhibition found in Candida tropicalis showing the largest inhibition (7. 23mm) beyond the inhibition done for Bacillus subtilis might happen because of the uneven diffusion of the active antimicrobial compound to the dishes. It still matched the theory since allicin has antibacteria and antifungal activity towards the species mentioned above.From the result, it can be concluded that garlic can be used as the antimicrobial compound in food to prevent foodborne disease and food poisoning. However, the concentration of garlic has to be concerned since it has strong odor and may be unpleasant to some people. 4. 1. 2 Coriander Table 4. 2 Observation result of inhibitory activity by coriander From Table 4. 2, it can be seen that coriander is found to be effective as an antimicrobial compound most in Bacillus subtilis, although some of the dishes showed no area of inhibitions.The disappearance of Bacillus subtilis in most of Petri dishes shown by no grow th sign indicated that coriander worked best to inhibit bacteria. This result matched with the previous literature stating that coriander inhibits food pathogenic bacteria, especially Gram-positive bacteria. However, coriander has the least inhibition activity towards Candida tropicalis and Aspergillus oryzae was found to be less susceptible to the volatile compound in coriander acting as antimicrobial compound. There were almost no area of inhibition found in every petri dish, proving that coriander did not affect mold and yeast.Since the literature stated that coriander has almost no antifungal activity and its activity toward yeast has not been examined, the result matched them. 4. 1. 3 Black Pepper Table 4. 3 Observation result of inhibitory activity by black pepper From the result of the experiment, it can be seen that black pepper is most effective when used against Bacillus subtilis, as many bacteria were inactivated, indicated by the area of clear zone, which in some plates, all of them doesn’t grow at all and so the area of clear zone can’t be measured.Aspergillus oryzae are quite susceptible as well to black pepper’s antimicrobial compound as the area of inhibition overall is large. While the most resistant microorganism from the experiment shown is Candida tropicalis, as the area of inhibition is relatively small. From the theory, black pepper shows antimicrobial activity against bacteria, molds, and yeasts, but the strongest towards bacteria, especially Grampositive bacteria. The result of the experiment matches the theory, as black pepper is very effective in stopping the growth of Bacillus subtilis, which is a Grampositive bacterium.It also inhibited the growth of Candida tropicalis and Aspergillus oryzae, so the result of the experiment matches the theory. 4. 1. 4 Potassium Sorbate Table 4. 4 Observation result of inhibitory activity by potassium sorbate From the result of the experiment, it can be seen that potassium sorbat e is very effective in stopping the growth of Bacillus subtilis, as in some plates it inhibited the growth of all the bacteria and so the area of clear zone can’t be measured. Antimicrobial activity can be seen as well towards Candida tropicalis and Aspergillus oryzae.According to the theory, potassium sorbate is very effective when used to inhibit the growth of bacteria, molds, and yeasts. The result of the experiment matches the theory, as potassium sorbate in this experiment is able to stop the growth of Bacillus subtilis, Candida tropicalis, and Aspergillus Oryzae. 4. 2 Microbial Defense Towards Antimicrobial Compounds 4. 2. 1 Bacteria (Bacillus subtilis) Table 4. 4 Table of diameter of inhibition zone of Bacillus subtilis in some condiments From the table 4. 4, it is shown that the most effective condiment in affecting the microbial defense of the Bacillus subtilis for its growth is arlic. Also, the least effective condiment for inhibiting the growth of Bacillus subtilis is coriander. According to the theory, garlic is effective for both Gram-negative and Grampositive bacteria, thus the inhibition zone is larger. Also, coriander is effective in inhibiting Gram-negative bacteria, as in the experiment the bacteria used was Gram-positive bacteria, thus, coriander is not effective in inhibiting Bacillus subtilis. The experiment result has shown the same result as the theory given. 4. 2. 2 Yeast (Candida tropicalis) Table 4. 5Table of diameter of inhibition zone of Candida tropicalis in some condimentsIn the table 4. 5, it shown that the most effective condiment in affecting the microbial defense and microbial growth of Candida tropicalis is garlic and the least effective is coriander. According to the theory, garlic is used as antifungal and is the most effective one in inhibiting the growth of bacteria, molds and yeast. Thus, the inhibition zone of garlic is the largest. Also, as coriander is mostly effective in inhibiting Gram-negative bacteria, the rate of inhibition of yeast is lower, so the inhibition zone is smaller. The experiment result has shown the exact result as the theory given. 4. 2. Molds (Aspergillus oryzae) Table 4. 6 Table of diameter of inhibition zone of Aspergillus oryzae in some condiments The experiment result has shown that the most effective condiment towards the inhibition zone in Aspergillus oryzae media is garlic and the least effective condiment is coriander. Referring to the theory, garlic is mostly used as antifungal and the most effective condiment used in the experiment to inhibit the growth of bacteria, mold, and yeast. Also, coriander is least effective in inhibiting the growth of Aspergillus oryzae as coriander is most effective in inhibiting gramnegative bacteria.In conclusion, the result of the experiment shows the same result as the theory given. CHAPTER V CONCLUSION Spices have different antimicrobial compounds able to inhibit the growth of various types of microorganisms. Based on the expe riments, garlic, coriander, and black pepper have the most effective activity in inhibiting the growth of bacteria, or in this case Bacillus subtilis. However, coriander was proven to have no antifungal activity by the absence of inhibition zone on the Petri plates with yeast and molds, in this case Candida tropicalis and Aspergillus oryzae.In addition, potassium sorbate is effective to inhibit the growth of all types of micoorganisms in the experiment: bacteria, yeast, and molds. The Bacillus subtilis bacteria, Candida tropicalis yeast, and Aspergillus oryzae molds are most susceptible by the presence of garlic. This means that the garlic has the highest effectiveness in affecting the defense of bacteria, yeast, and molds. In contrast, the growth of bacteria, yeast, and molds is least affected by the presence of coriander.
