Judul: Respon Stres Dengan Penanda Kortisol &lam Urine Monyet Ekor Panjang (Macoca fnscicularis) setelah Mengalami Transportmi
Abstrak: Stress during tranqxtaticm is one of the primary ocm*ing facia in eqmhng non human primate to the target country- Cartid mdabdite rate measuclements of urine as one of the @es makers were mwhctd using ELISA on 30 adult f d e M-Q fuscdarLs 0 after 24 hours of tmqatation. The aims of tbe research were to investigate the mpnse indud by tmmsp&atioa, using windowed cage aad closed, and &&rent &ansgortatiw fed rations. The result showed h t there was a differearn in he existeoce of urine cortisol levels of Mf at the first 8 hours, which decrease until reaching normal rate after 24 hours transportation (P<0.05). The animals which were placed in windowed cages had a lower corliso! levels thao those in the clod cages. This indicated that the animals in window cages had a lower response to stress. It did not have any differences (M.05) on the five different fd rations bring transportation. The results of this research indicated that window cages were more appropriate compred ta dosed cages.

Judul: Biological study of longtailed macaques (macaca fascicularis) which experience transportation
Abstrak: During transportation of monkeys, environment conditions change, cause stress to the animals and consequently the rate of body metabolism increases. This condition influences the stability of biological and physiological activities of the animals, and could cause death. It is therefore necessary to apply appropriate management during transportation of the monkeys. This study was conducted in Bogor and Kuningan counties in two periods, 26 days in September 2003 for transportation time of eight hours, and another 28 days in October – November 2003 for transportation time of 24 hours. The transportation times were treatments applied in the experiment, in which 30 adult female monkeys of 2.5-3.5 kgs of weight were used for each treatment. In addition, five types of rations were given during transportation, and the monkeys were put in two types of individual cages, with and without windows, to observe the effect of open and closed cages. A complete randomized design, arranged factorially was used. Total feed consumption, coefficient of digestibility, changes in body weight, and behaviour of animals during and after transportation were measured in this study. The results of the study indicated that transportation caused changes in almost all aspects of the treatments but, there were no significant differences found due to the type of transportation cages used. Based on the recovery times needed to get back to normal non-stressed behaviour, it was found that longer transportation periods (24 hours vs eight hours) needed longer recovery times. It is recommended that rations during transportation have high levels of protein (monkey chow), and be supplemented with appropriate fruits to furnish the raw fiber and high palatibility.

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.
