Judul: Physiological Response and Estrus Characteristics of Sumatran Composite Sheep that Given Flushing Ration at the Sumatera Martabe Farm
Abstrak: Penelitian ini bertujuan mempelajari pengaruh ransum flushing terhadap respon fisiologis dan karakteristik estrus induk Domba Komposit Sumatera di Sumatera Martabe Farm. Jumlah domba yang digunakan sebanyak 10 ekor induk domba Komposit Sumatera yang memiliki rata-rata bobot badan 43,41 kg/ekor, ditempatkan pada kandang individu. Perlakuan yang diberikan meliputi 2 ransum, yaitu ransum kontrol (SMF) dan ransum flushing (Flushing). Peubah yang diamati adalah respon fisiologis, konsumsi nutrien berdasarkan bobot badan metabolis, dan karakteristik estrus (onset estrus, durasi estrus, dan respon estrus). Data yang diperoleh dianalisis dengan t-test independent sample menggunakan program IBM SPSS Statistic 25. Hasil penelitian menunjukkan ransum flushing yang digunakan berpengaruh nyata (P<0,05) meningkatkan konsumsi nutrien, dan mempercepat onset estrus dan durasi estrus dibandingkan dengan ransum SMF, namun tidak berpengaruh nyata terhadap respon fisiologis pada Domba Komposit Sumatera. Ransum flushing dapat meningkatkan konsumsi nutrien, mempercepat onset estrus dan durasi estrus , namun tidak mengganggu status fisiologis dari induk Domba Komposit Sumatera, This research aimed to study the effect of flushing rations on the physiological response and estrus characteristics of Sumatran Composite Sheep at the Sumatera Martabe Farm. A total of 10 Sumatran Composite Sheep with an average body weight of 43,41 kg/ekor, were used and placed in individual pens. The treatments consisted of 2 groups: a control ration (SMF) and a flushing (Flushing). The variables observes were physiological response, nutrient consumption based on metabolic body weight, and estrus characteristic (onset of estrus, duration of estrus, and estrus response). The data obtained were analyzed by independent sample t-test using the IBM SPSS Statistic 25 Program. The results show that flushing diet significantly (P<0,05) increased nutrient consumption and accelerated onset and duration of estrus compared to the SMF diet. However it, did not significantly affect the physiological response of Sumatra Composite Sheep. The flushing diet can enchance nutrient consumption, accelerate onset and duration of estrus, without disrupting the physiological status of Sumatra Composite Sheep.

Abstrak: Penelitian ini bertujuan mengevaluasi pengaruh ransum flushing terhadap konsumsi nutrien dan metabolit darah induk domba komposit Sumatera pada fase pra-kawin dan pasca-kawin. Penelitian ini menggunakan 10 ekor domba komposit Sumatera yang telah beranak satu kali (rataan bobot badan 43,41, This research aims to evaluate the effect of flushing ration on nutrient intake and blood metabolites of composite Sumatera ewes at pre-mating and post-mating. This research used 10 composite Sumatera ewes that had given birth once (average body weight 43.41

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.
