Judul: Bakteri Enteropatogen pada Penderita Diare dan Kondisi Higiene Sanitasi Lingkungan Inang di Kecamatan Cigudeg Kabupaten Bogor
Abstrak: Diarrhea is still be one of the top ten disease that occur in Indonesia. Some bacterial enteropathogens are diarrhea-causing bacteria, such as Salmonella sp., Shigella sp., and Vibrio cholerae. The spread of diarrheal diseases caused by poor personal hygiene and environmental sanitation. This study aims to assess the presence of bacterial enteropathogens, personal hygiene, and environmental sanitation of diarrheal patients in Cigudeg District of Bogor Regency West Java. Stool samples from 50 diarrheal patients have been identified the presence of its bacterial enteropathogen. Personal hygiene observations conducted on 50 diarrheal patients and its settlements environmental-sanitation. The results of the stool’s identification of diarrheal patients showed 2 isolates of Salmonella sp., and 2 isolates of Shigella sp., but there were no V. cholerae. Analysis of personal hygiene showed as much as 60.1% of respondents did not wash their hands with soap before eating. Hygiene’s data of food and beverage sanitation behavior suggested that as many as 85.1% of respondents eat their food about 1-12 hours after it been cooked. Observations showed the state of environmental sanitation related sanitary sewer waste water was not good.

Judul: Shigella, Leucocytes, and Hematocrit from Diarrheal Patient in Cangkurawok Healt Center, Dramaga, Bogor
Abstrak: Diarrheal is one of diseases caused died of baby and children. On 2008 in Indonesia outbroken diarrheal in 15 province (8.433 patient and 209 died). The research for isolate and identification Shigella bacteri, show total and differentiation leucocytes, and content of hematocrit to diarrheal patient. One hundred sample of fecal isolated from diarrheal patients in Cangkurawok central healt by rectal swab method in Salmonella Shigella Agar (SSA) and taken blood with microhematocrit method. Identification by some biochemistry, they are MR-VP, Urease, H2S on TSIA, Carbohydrates fermented, Indole, and Cimon citrate.Ten of expected Shigella bacteri, only seven sample that showed it is Seven sample that content of normal hematocrit, one sample that increase leucocytes with high percentage lymphocytes and low percentage neutrophil., Diare merupakan salah satu penyakit penyebab kematian balita dan anak-anak. Pada tahun 2008 di indonesia terjadinya KLB (Kejadian Luar Biasa) diare di 15 provinsi (penderita sebanyak 8.433 orang dan jumlah kematian 209 orang). Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi bakteri Shigella, melihat jumlah dan deferensiasi leukosit, dan kadar hematokrit pada penderita diare. Sebanyak 100 sampel tinja. berhasil diisolasi dari penderita diare di puskesmas Cangkurawok dengan metode rectal swab pada media Salmonella Shigella Agar (SSA) dan pengambilan darah dengan metode mikrohematokrit. Identifikasi dengan beberapa uji biokimia, yaitu uji MR-VP, Uji Urea, Uji H2S pada TSIA, uji fermentasi karbohidrat, uji indol, dan uji sitrat Sepeluh dari bakteri yang diduga Shigella, hanya tujuh sampel yang berhasil menunjukkan bakteri Shigella.Ketujuh sampel tersebut kadar hematokritnya normal, satu sample menunjukkan jumlah leukosit yang tinggi dengan persentase limfosit yang tinggi dan neutofil yang rendah.

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.
