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

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: Analisis dan Implementasi Certificate Authorities (CA) pada Public Switched Telephone Network (PSTN)
Abstrak: Secure Telephone Protocol has ability to authenticate involved party and keep the secrecy of the message sent over the protocol. The secrecy of the message archieved by using symmetric key cryptographic scheme, and authentication archieved using public key cryptographic scheme. One of several party involved in the protocol and hold an important function called Certificate Authorities or CA. CA responsible for generating public key pair for other party involved in the protocol. When CA generates public key pair, several primitive cryptographic scheme used for guarantee the security of the key. Two of them are hash function SHA-1 and El-Gamal public key scheme embedded in Digital Signature Algorithm scheme. The prototype implementing the scheme above developed using Java programming language with JCE addition from Bauncy Castle. The analysis towards implemented prototype indicates that the prototype still has some flaws to be implemented in real world.
