Abstrak: The aim of this study was to know the factors related with hygiene practices among food handlers at canteen in Bogor Agriculture University. Survey of KAP (knowledge, attitude, and practices) were used to know the relationship of knowledge and attitudes with their practices as its factors. Thirty nine food handlers were taken sampling randomly from sixty seven canteen in Bogor Agriculture University and become respondents for questionnaire about hygiene in handling food which is divided in to three aspect: personal hygiene, hygiene of production, and hygiene of facilities. The data were analyzed using the SPSS 16.0. A majority respondents have good knowledge (94.9%), attitude (100%), and practices (97.4%). Statistic analysis showed significant difference (p<0.05) between the relationship of knowledge, attitude, and main occupation with their practices

Judul: Studi Knowledge, Attitude, and Practice (KAP) Higiene Pangan pada Food Handler di Kios Makanan di Dalam dan Luar Kampus IPB Dramaga, Bogor
Abstrak: Food besides giving benefit for human health is also easy to be contaminated with various contaminants so that can cause disease (foodborne disease). One of many factors influencing incidence of foodborne disease is food handler. Important factors on food handlers which have impacts on food hygiene are knowledge, attitude, and practice. The purpose of this study was to determine the level of knowledge, attitudes, and practices; correlation between knowledge, attitudes, and practices; and risk factors of food hygiene practices. Total of 77 kiosks from 373 food kiosks inside and outside of IPB campus in Dramaga, Bogor was sampled randomly. The data include characteristics and KAP food handler which is obtained from interviews with respondents using questionnaires and observations, and level surface sanitizing food handlers hands and dishes in kiosks with RODAC test (total plate count and the number of Staphylococcus aureus). This study showed that most of the food handlers were categorized as good in knowledge (55.8%) and practices (70.1%), while most of food handlers’ attitude were categorized as moderate (51.9%). The level of hygiene in food kiosks was mostly good (76.6%). Risk factors which influenced on hygiene level in food kiosks were age (young age, OR = 12.6), the participation in extension (never exposed to extension, OR = 8.3), and attitude (bad attitude, OR = 43.7). Characteristic variables that had significant correlation with knowledge, attitude, and practice were the correlation between extension and knowledge (r = 0.59), monitoring and knowledge (r = 0.63), work experience and attitude (r = 0.35), purpose of business and attitude (r = 0.51), extension and attitude (r = 0.53), and age and practice (r = 0.71). This study showed significant correlation (p<0.05) between knowledge and attitude (r=0.73), knowledge and practice (r=0.79), and attitude and practice (r=0.84). More than half of food kiosks showed bad sanitation level of hands and plates. Practice of personal hygiene showed significant correlation with score the number of Staphylococcus aureus in food handler hand (r=0.15). The results of this study should be considered as potential threat to consumer health inside and outside of IPB campus in Dramaga, Bogor.

Judul: Pricing of Lookback Options with Floating Strike Price Using The Monte Carlo Method
Abstrak: Opsi lookback adalah opsi yang payoff-nya bergantung pada harga saham terbesar atau harga saham terkecil yang dicapai selama masa berlaku opsi. Opsi lookback dikatakan dengan floating strike price jika nilai dari strike price sebesar harga saham pada saat jatuh tempo. Nilai hampiran opsi lookback ditentukan dengan metode Monte Carlo, sedangkan nilai eksak didapat dari nilai simulasi terbesar yang mampu dihitung oleh komputer. Berdasarkan hasil penghitungan, nilai galat relatif yang dihasilkan semakin kecil dengan semakin bertambah banyaknya simulasi yang dilakukan, sehingga metode Monte Carlo untuk menghitung harga opsi lookback dengan floating strike price konvergen ke nilai eksaknya., Lookback option is an option whose payoff depends on the maximum or minimum of the asset price reached during the option period. The lookback option is said to be a floating strike price if the value of the strike price is equal to the stock price at maturity. The value of the lookback option is determined by the Monte Carlo method, while the exact value is obtained from the largest simulation value that the computer can compute. Based on the calculation results, the resulting relative error value get smaller with the increasing number of simulations performed. Therefore, the Monte Carlo method to calculate the price of the lookback option with the floating strike price converges to the exact value.
