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: Blood Chemistry Profiles on the Long-tailed Monkeys (Macaca fascicularis) in Acclimation Condition.
Abstrak: This study was aimed to evaluate a blood chemistry profiles especially glucose, cholesterol, triglycerides, SGPT, SGOT, serum urea, and creatinin of long-tailed monkey (Macaca fascicularis) in acclimation condition. Four years old of ten Macaca fascicularis was used in this study. Macaca fascicularis were placed in two rooms which were contained five monkeys with individual cage. This research divided into three stages: adaptation stage for seven days (without temperature and humidity setting), acclimation stage for 14 days (with temperature setting at 25°C temperature and 78% rel. humidity), and postacclimation stage for 14 days (without temperature and humidity setting). Blood collection was done at the 7th day (adaptation stage); 8th, 11th, 14th, and 21st day (acclimation stage); and 35th day (post-acclimation stage). The results showed that adaptation and post-acclimation stage, the animal model showed signs of stress. Stress in the adaptation stage was indicated by the decreasing in blood glucose, while the stress in the post-acclimation stage was indicated by decreased levels of triglycerides. It could be supposed that temperatur conditions of acclimation stage (25.79 ± 1.16)°C dan (80.19 ± 9.05)% relative humidity is more comfortable for Macaca fascicularis.

Judul: Formulasi Algoritme Operasi Grup Jacobian Kurva Hyperelliptic ...
Abstrak: Dalam geometri aljabar, kurva hyperelliptic merupakan bentuk umum dari kurva elliptic. Kurva ini apabila dikenakan pada suatu lapangan berhingga akan membentuk suatu grup siklik. Pada kriptografi, khususnya enkripsi kunci publik, grup siklik yang dibangkitkan oleh kurva elliptic sudah banyak diteliti. Bahkan untuk kurva ini sudah memiliki standar oleh National Institute of Standard and Technology (NIST) Amerika. Sedangkan, untuk grup yang dibangkitkan oleh kurva hyperelliptic masih memiliki kekurangan dalam hal komputasinya. Tujuan dari penelitian ini adalah mengkonstruksi suatu lapangan berhingga pada , memilih kurva hyperelliptic atas lapangan hingga yang memenuhi kriteria keamanan untuk kriptografi, dan membuat formulasi operasi grup kurva hyperelliptic menggunakan algoritme Cantor. Dalam merekonstruksi lapangan hingga, terlebih dahulu tentukan dimensi dari lapangan hingga tersebut dan polinomial tak-teruraikan. Kemudian dipilih kurva hyperelliptic atas lapangan tersebut. Pada penelitian ini, kurva yang dipilih adalah = + + dengan lapangan hingga . Berdasarkan kurva yang dipilih, akan dibentuk suatu operasi grup dengan menggunakan algoritme Cantor, sehingga menjadi lebih aritmatik. Eksplorasi kurva hiperelliptic dilakukan untuk mengetahui keamanan dari kurva yang dipilih. Dengan menyusun algoritme operasi grup dari kurva yang dipilih, diperoleh perhitungan yang lebih aritmatik dan dapat diimplementasikan pada kriptografi kunci publik. Dari segi keamanan kurva telah memenuhi standar sehingga tahan terhadap serangan-serangan seperti Poligh-Hellman, Polard- , ataupun Frey-Ruck secara teorema.
