Judul: Studi Knowledge, Attitude, and Practice (KAP) Higiene dan Sanitasi Pedagang Daging Ayam di Pasar Tradisional di Provinsi DKI Jakarta
Abstrak: Chicken meat as a source of animal protein is very popular and common in Indonesia, including in Jakarta. Chicken meat is easy to find and its price is relatively cheaper than beef meat. Traditional markets are the most common place for Indonesian people to buy their needs, especially food. One of factors affecting the safety and quality of fresh chicken meat is application of hygiene and sanitation in markets. The aims of this study were to observe the knowledge, attitude, and practices of chicken meat vendors and to evaluate the level of hygiene and sanitation of chicken carcass at vendors in traditional markets in the Province of DKI Jakarta and correlated to each variables. This study was conducted by cross-sectional using questionnaires for interview respondents and observation on practices of hygiene and sanitation. The respondents were chicken meat vendors who traded in the traditional market in five districts in the Province of DKI Jakarta. Total of 217 respondents was involved in this study. The study used cluster random sampling method for identification the market and identification of sample cluster was done using probability proportional to size method. The data were analyzed descriptively and the association among variables was determined with gamma tests. Most of respondents (n=209; 96.3%) had knowledge categorized from moderate to good. There was no respondents whose attitude were categorized as bad, they were categorized in attitude as moderate (n=72; 33.2%) and good (n=145; 66.8%). Most of respondents (n=174; 80.2%) was categorized as moderate in practices of hygiene and sanitation. Further analysis showed that the educational levels were significantly correlated with knowledge (p<0.05), experiences were significantly correlated with the knowledge, and age was significantly correlated with the attitudes (p<0.05). The significant associations (p<0.05) were also showed between knowledge and attitude and then attitude and practice.

Judul: Incidence Salmonella spp.in chicken meat sold at the markets in West Jakarta
Abstrak: This research was aimed to know the existence of Salmonella spp. in chicken meat, handling implementation of chicken meat and water utilized in supermarkets and traditional markets of West Jakarta .. A sum of 300 samples consist of 200 samples of 20 supermarkets (80 samples of chicken meat, 100 samples of swab and 20 samples of water) while 100 samples from 10 traditional markets (40 samples chicken meat, 40 samples swab and 20 samples of water) were tested on the existence of Salmonella spp. SNI 19-2897-1992, method of identification. The testing product indicated that 19 (23,75%) samples from 80 chicken meat samples taken from supermarkets were contaminatied by Salmonella spp,.while in traditional market were negative from Salmonella spp .. Observation against sanitation and hygiene factors of supermarket was done with interviews and filling questionairies. Datas from this observation were analyzed by testing of chi-square to know the association of the factors sanitation and hygiene and contamination of Salmonella spp. of chicken meat. The test result showed that there were significant association between sanitation and hygiene factors with the presence of Salmonella spp. in chicken meat at supermarkets.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
