Judul: Efisiensi Penggunaan Protein Ransum Komplit yang Mengandung Indigofera zollingeriana dan Limbah Tauge pada Penggemukkan Domba Lokal Jantan
Abstrak: The aim of this study was to investigate the protein utilization efficiency of completed ration that contained 30% of Indigofera or sprout bean waste. Two groups of local rams consisted of 8 heads of Garut rams and 8 heads of UP3-Jonggol rams were involved in this experiment. The rams were 9 months with live weight average at 14,93 ± 1,38 kg. Two different rations, R1 (30% indigofera + 70% concentrate) and R2 (30% limbah tauge + 70% concentrate) were used as treatments. Both of feeds and water were given ad libitum. The parameters measured were feed consumption, protein balance and body weight and the efficiency protein utilization. Factorial Completely Randomized Design was used as experimental design. First factor was ration and the second factor was ram’s breed. The data were analized with analysis of variance, and the means of each treatment were tested with the contrast orthogonal test. The result showed that R2 resulted in higher protein dry matter and protein consumption and protein retention (P<0,01) than those of R1, but there was no significant difference in protein digestibility, the efficiency protein utilisation and average daily gain. There were no interaction between both main factors. It was concluded that 30% of bean sprouts waste in rams ration could increased dry matter and protein intakes and protein retention compared to indigofera ration.

Judul: Kecernaan Ransum yang Mengandung Indigofera sp. atau Limbah Tauge pada Domba UP3 Jonggol dan Domba Garut
Abstrak: Fluktuasi ketersediaan pakan baik kuantitatif maupun kualitatif merupakan tantangan dalam peningkatan produktifitas ternak ruminansia di daerah tropis. Musim kemarau umumnya menurunkan produksi dan kualitas nutrisi hijauan dengan akibat menurunnya tingkat produktifitas ternak, seperti tingginya angka kematian dan rendahnya laju pertumbuhan. Pemberian leguminosa seperti Indigofera sp. dan bahan pakan inkonvensional seperti limbah tauge dalam ransum untuk ternak dapat menjadi solusi pemecahan masalah dalam usaha peternakan di Indonesia. Penelitian ini bertujuan untuk membandingkan dua jenis perlakuan ransum pakan yang mengandung Indigofera sp. atau limbah tauge terhadap performa produksi, konsumsi dan kecernaan zat makanan serta Total Digestible Nutrient (TDN) pada domba UP3 jonggol dan domba garut. Penelitian dilakukan dari bulan Juli sampai Oktober 2011 di Laboratorium Lapang Ilmu Produksi Ternak Ruminansia Kecil Blok B, Fakultas Peternakan, Institut Pertanian Bogor. Ternak yang digunakan sebanyak 8 ekor domba garut dan 8 ekor domba UP3 jonggol yang berumur 7-8 bulan dengan rataan bobot badan awal 14,93±1,38 kg. Pakan yang diberikan dalam bentuk pellet dengan rasio hijauan dan konsentrat 30:70 yang terdiri dari R1 (ransum dengan kandungan Indigofera sp. 30%) dan R2 (ransum dengan kandungan limbah Tauge 30%). Rancangan percobaan menggunakan rancangan acak lengkap pola faktorial 2x2 dengan faktor pertama adalah je domba (B1 = UP3 jonggol dan B2 = garut), faktor kedua yaitu jenis ransum (R1 = Indigofera sp. dan R2 = limbah tauge). Ulangan dilakukan sebanyak empat kali. Analisis data menggunakan analisis sidik ragam (Analysis of Variance) dan uji orthogonal kontras. Peubah yang diamati adalah performa produksi, konsumsi zat makanan ransum, kecernaan zat makanan ransum dan Total Digestible Nutrient (TDN) ransum.

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.
