Judul: Studi Pengetahuan, Sikap dan Praktik Kesejahteraan Hewan dan Biosekuriti pada Petugas Instalasi Karantina Hewan Primata Balai Besar Karantina Pertanian Soekarno Hatta
Abstrak: This study was conducted to analyze knowledges, attitudes and practices of installation personnels related to animal welfare and biosecurity to correlate knowledge, attitudes and practices of installation personnels to measure the level of animal welfare and biosecurity in animal quarantine installations. Data were collected from animal quarantine premises for exported primate (Macaca fasicularis). The level of knowledge, attitudes and practices of respondences measure by interviews and observation using the questionnaires and checklist. Data analyzed to determine associations between these variables using chi square and Gamma test. This research revealed that veterinarian knowledge correlated to their attitude with the level of correlation 0.694, and the care taker knowledge correlated to their attitude with the level of correlation 0.575. This study also noticed that the characteristics of respondents showed no correlation between animal welfare and biosecurity implementation, while the knowledge and attitude of veterinarians showed a strong correlation between animal welfare and biosecurity implementation with medium correlation level (r = 0.694). On the other hand the knowledge and attitude of care takers showed a strong correlation between the animal welfare and biosecurity with medium correlation level (r = 0.575). In conclusion most of the knowledge, attitude and practice of the veterinarians were verygood and knowledge, attitude and practice of the managers and care takers were good.

Abstrak: This study was conducted to analyze level of knowledge, attitudes and practices of installation personnels related to biosecurity, correlations among knowledge, attitudes and practices of installation personnels related with biosecurity in animal quarantine installations and level of biosecurity measures in quarantine installation. Measuring the level of knowledge, attitudes, and practices of respondents conducted with interviews using questionnaires and observation. Data analysis to determine associations between these variables using Spearman and Pearson correlation test. This research revealed that knowledge and attitude of manager significantly correlated with low correlation level, knowledge and practice of veterinarian significantly correlated with medium correlation level and worker practice and attitude significantly correlated with medium correlation level. Biosecurity level in quarantine installation determined by manager’s knowledge and practice, veterinarian’s practice and worker’s practice.

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.
