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.

Abstrak: Salmonella is one of bacteria that can cause diarrhea with the infasive mechanism, which can influence the system immune. The objective of this research is isolating Salmonella from diarrhea’s faeces and knowing the number and differentiation of leucocyte, and hematocryte value of diarrhea patient. The faecal samples were isolated in SSA media. The identification of isolates based on gram staining and biochemical assay through MR (Methyl Red), VP (Voges Proskauer), urease, H2S, KCN, indole, and citrat. Hematogram analysis include hematocryt value, number of leukocytes, and calculated the percentage of leukocyte differentiation type. Five of 100 faecal samples showed that they had black colonies in SSA media. Then based on the biochemical assay, three of those samples had characteristic of Salmonella bacteria, positive result in MR and citrate, and negative in VP, urease, H2S, KCN, and indole. The patients who identified as Salmonella carrier had the normal hematocryt value, normal and low number of leucocyte, and the varying presentation of leucocyte differentiation.

Abstrak: An American option is an option that can be exercised at the strike price anytime before or on the date of expiration. In this thesis, Monte Carlo simulation for valuation of American option is presented. Monte Carlo simulation is one of the numerical methods used to determine the price of American options. The simulation provides several examples of initial stock price , rate of interest , exercise time , volatility , and strike price K. The simulation study shows the cost of the option c decreases when S increases, c decreases when r increases, c increases when T increases, c increases when  increases, and c increases when K increases.
