Judul: Respon Komposisi Susu Kerbau (Bubalus bubalis) terhadap Pemberian Pakan di Peternakan Doa Anak Yatim
Abstrak: Buffalo is an animal that is often used for meat and milk productions, work, sport and social status. The main potential products of buffalo are meat production and work; the other potential which people currently start looking for is buffalo milk because it has good nutrient content. Peoples have already used the milk for traditional food or medicine. This experiment is aimed at studying the response in milk composition to feed given by farmer. The main feed given by farmer is rice straw without additional concentrate. Variables measured were feed given, feed dry matter (DM), ash, crude protein (CP), fat, crude fiber (CF) and energy intakes, milk composition measured by chemical analysis and milko tester, and body weight estimated from various body size measurements. Data were analyzed descriptively. The result showed that rice straw obtained in September has the best nutrient content (the highest CP and energy contents, but the lowest CF content) causing the highest intake. Rice straw that were given to buffaloes had no different effects on milk compotition and body weight among buffaloes

Judul: Tingkah Laku Kerbau Rawa yang Dipelihara Secara Feedlot yang Diberi Ransum Dengan Suplementasi Campuran Garam Karboksilat Kering (CGKK)
Abstrak: At present buffalo farming system is still traditional with a relatively low quality of feed. Improvement of the feed quality needs to be developed. The experiment was aimed to study the behaviour and physiological parameters of swamp buffalo as a response of different treatment of feed supplemention protected Lemuru fish oil in dried of carboxylate salts mixture (DCM) 0% and 4,5%. The animals used were six heads of male buffaloes. Observations were conducted in three times, in the morning (8:00 am - 10:00 am), around noon (12:00 am – 2:00 pm) and afternoon (3:00 pm - 5: 00 pm). The parameters included eating behaviour, agonistic, eliminative, grooming, and vocalization. Physiological parameters measured were pulse rate, respiration rate, and rectal temperature. Data analysis used were Man Whitney and Friedman test to analysis frequency different of while two treatment., where as the data of physiology were analysed by t test method. The results show that the eating, agonistic, and eliminative behaviour were dominantly presented in the morning and afternoon both in the two treatments. Grooming behaviour occurred during the day. The physiology of the buffalo bull were not different in both feed treatment. It is concluded that the feed treatments had no effect on the behaviour and phisiology of the swamp buffalo, therefore CGKK can be recommended as a good quality feed for local buffalo.

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.
