Abstrak: This study was conducted to evaluate correlation between characteristics (sex, age, graduate level, entrance to Bogor Agricultural University, and activity on organisations), knowledge and attitude of Veterinary Students of Bogor Agricultural University on foodborne diseases. The data collection was carried out using quetionnaires for 239 respondents from August 2010 to January 2011 by stratified random sampling. The significant possitive correlation was observed between knowledge and age, graduate level, and activity on organisations (p<0.05), nevertheless sex and entrance to Bogor Agricultural University did not show a correlation with knowledge (p>0.05). The significant possitive was found between attitude and entrance to Bogor Agricultural University (p<0.05). In this study, the correlation between sex, age, graduate level, and activity on organisations and attitude were not found significantly (p>0.05). There was no correlation was observed between knowledge and attitude (p>0.05).

Judul: Sikap Mahasiswa Fakultas Kedokteran Hewan Institut Pertanian Bogor terhadap Kesejahteraan Hewan
Abstrak: The aim of this study was to observe the attitude of veterinary students on animal welfare at the Faculty of Veterinary Medicine, Bogor Agricultural University. This study was cross sectional which was conducted through survey using questionnaires. The questionnaires involved 6 categories of questions on animal welfare. Total of 200 veterinary students was included in this study which consisted of 4 levels of study year, i.e., 1st, 5th, 7th, and 9th semester students. The study showed that the veterinary students had mostly attitude on animal welfare with category from neutral to positive level. The 9th semester students had positive attitude on general animal welfare. The students at 5th semester had positive attitude on welfare of pets, welfare of wild animals, and welfare of entertain use animals. All grade of students showed positive attitude on welfare of livestock animals and veterinary education. There was a significant correlation between sudent grade and attitude on animal welfare, whereas higher grade of students showed more positive attitude on general animal welfare. On the other hands, higher grade of students showed less negative of attitude on welfare of wild animals and entertain use animals. The female students had positive attitude on general animal welfare, welfare of pet animals, welfare of livestock animals, and welfare of wild animals more than the male ones. Nevertheless, the male students had positif attitude on welfare of entertain use animals more than the female ones. Both of male and female students had positive attitude on veterinary education. From this study, it should be suggested to deliver the animal welfare course in lower grade of students and the animal welfare concept should be applied to all courses in connection with animal handling.

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.
