Judul: Peluang Terjadinya Diare Akibat Konsumsi Produk Hewani di Kecamatan Bogor Barat
Abstrak: Diarrhea is still one of public health’s major problems in Indonesia, both in terms of morbidity or death. The main risk factor of diarrhea and foodborne disease cases is due to consumption of animal products with poor handling, including cross contamination from raw food to cooked products, insufficient cold storage temperature, insufficient temperature and cooking time, and poor handling process after the cooking process. Therefore, it is necessary to determine exposure opportunities because of animal products. Those exposure opportunities are calculated based on the number of attack risk (AR), which shows the percentage of exposed people who get diarrhea when they are eating or not eating certain types of animal products. While the relative risk of animal products that can cause diarrhea is calculated based on comparison attack risk (AR) an exposed people who eating or not eating certain types of animal food products. It is also known as relative risk (RR). Based on survey on 400 respondens (housewifes) in West Bogor, there are six main animal food products that cause diarrhea. There products are baked fish, seasoning chicken, and semur meat. The result showed that the animal food products infection are baked fish (RR=4.11), seasoning chicken (RR=3.58), semur meat (RR=1.85), baked chicken (RR=1.76), seasoning fish (RR=1.53), and salt fish (RR=1.31). The highest RR value has great effect to cause numbers of diarrhea incidence due to consumption of animal products.

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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
