Judul: Penambahan Minyak Nabati pada Ransum Berbasis Limbah Pengolahan Kedelai terhadap Konsumsi, Profil dan Metabolit Darah Domba Garut Betina
Abstrak: Penelitian ini bertujuan untuk mengevaluasi performa ternak, gambaran profil dan metabolit darah domba Garut betina yang diberi pakan limbah pengolahan kedelai dengan penambahan minyak nabati. Perlakuan yang diberikan yaitu P0 (ransum berdasarkan pakan yang diberikan di peternak atau kontrol) dan P1 (ransum berdasarkan pakan yang diberikan di peternak dengan penambahan minyak nabati 5.2%). Penelitian ini menggunakan 10 ekor domba betina yang sudah pernah beranak dengan rataan bobot badan 24.87±4.02 kg. Parameter yang diamati yaitu konsumsi bahan kering, protein kasar, lemak kasar, serat kasar, Beta-N, profil darah (hematokrit, hemoglobin, leukosit, eritrosit) dan metabolit darah (glukosa dan kolesterol). Data dianalisis menggunakan metode T-test. Hasil penelitian menunjukan bahwa penambahan 5.2% minyak nabati di dalam ransum mempengaruhi (P<0.01) konsumsi lemak kasar, namun tidak berpengaruh (P>0.05) terhadap konsumsi bahan kering, konsumsi protein kasar, konsumsi serat kasar, konsumsi Beta-N, metabolit darah dan profil darah domba betina. Simpulannya adalah penambahan minyak nabati 5.2% di dalam ransum berbasis limbah pengolahan kedelai mampu meningkatkan konsumsi lemak kasar, namun tidak mempengaruhi konsumsi bahan kering, protein kasar, serat kasar, dan Beta-N, dan menghasilkan profil dan metabolit darah domba betina yang normal.

Judul: Penambahan Minyak Biji Bunga Matahari Terhadap Profil Darah Domba Garut Betina pada Status Faal Berbeda
Abstrak: Sunflower seed oil is one of fat that can be used as an energy sources. The study was conducted to evaluate the effect of sunflower seed oil in premating, pregnant and lactation in eight Garut ewes with body weight 22.12±1.69 kg used in completely randomized nested design. The status of physiology (premating, pregnant, and lactation) nested in two treatment, control (without sunflower seed oil) and 4% sunflower oil addition in the ration with four replications. The parameters observed were dry matter, crude protein, crude fat intake, and blood profiles (haemoglobin, hematocrit, erythrocytes, leukocytes, MCV, MCHC, and leukocyte differentiation). Result showed that the addition of 4% sunflower seed oil was not affected to blood hematology, but the status of pregnant and lactation tends to increase erythrocytes and percentage of basophils. Dry matter, crude protein, and crude fat intake in pregnant and lactating ewes were higher than premating. Crude fat intake in 4% sunflower seed oil treatment was higher than control. It was concluded that the addition of 4% sunflower seed oil was not interfere blood hematology in premating, pregnant, and lactation ewes.

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.
