Judul: Creep Feed with Different Protein Sources On Hematology and Blood Metabolite Profiles of Weaned Lambs
Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh pemberian ransum creep feed dengan sumber protein yang berbeda yaitu indigofera dan tepung maggot terhadap profil hematologi dan metabolit darah pada domba dorper lepas sapih. Penelitian ini menggunakan 21 ekor domba dorper lepas sapih dengan Rancangan Acak Lengkap (RAL) terdiri dari 3 perlakuan dan 7 ulangan. Perlakuan terdiri dari PM = pakan Martabe Farm, P1 = creep feed mengandung indigofera, dan P2 = creep feed mengandung tepung maggot. Peubah yang diamati pada penelitian ini yaitu konsumsi nutrien (bahan kering, protein kasar, lemak kasar, serat kasar), profil hematologi (eritrosit, leukosit, hematokrit, hemoglobin, diferensiasi leukosit) dan metabolit darah (glukosa, kolestrol, dan blood urea nitrogen). Hasil penelitian menunjukkan bahwa pemberian ransum creep feed dengan sumber protein indigofera atau tepung maggot meningkatkan konsumsi nutrien tetapi tidak mengganggu profil hematologi dan metabolit darah pada domba dorper lepas sapih. Disimpulkan bahwa penggunaan indigofera atau tepung maggot dalam ransum creep feed mampu meningkatkan jumlah eritrosit dan BUN (Blood Urea Nitrogen) dalam darah namun masih berada dalam kisaran normal., This research was aimed to analyze the effect of providing creep feed rations with different protein sources indigofera and maggot meal on hematology and blood metabolite profiles of weaned Dorper lambs. This study used 21 weaned Dorper lambs in a Compeletely Randomized Design (CRD) with 3 treatments and 7 replicates. The treatments consisted of PM = feed of Martabe Farm, P1 = creep feed containing indigofera, and P2 = creep feed containing maggot meal. Parameters measured were nutrient intake (dry matter, crude protein, crude fat, crude fiber), hematology (erythrocytes, leukocytes, hematocrit, hemoglobin, leukocyte differentiation), and blood metabolite (glucose, cholestrol, and blood urea nitrogen). The results showed that providing creep feed rations either with indigofera or maggot meal increased nutrient intake but did not change the hematology and blood metabolite profiles of weaned Dorper lambs. It is concluded that utilization of indigofera or maggot meal in creep feed increased erythrocytes and BUN (Blood Urea Nitrogen) levels in the blood, yet still remains within the normal range.

Judul: Feed Additive containing Black Soldier Fly Meal and Black Soldier Fly Oil on Blood Profile in Weaned Lambs
Abstrak: Penelitian ini bertujuan mengetahui pemberian pakan tambahan mengandung tepung dan minyak black soldier fly terhadap profil darah anak domba lepas sapih. Penelitian ini menggunakan 10 ekor anak domba lepas sapih. Anak domba dibagi menjadi 2 kelompok perlakuan dan 5 ulangan. Perlakuan yang diberikan terdiri dari P1 = konsentrat komersial + rumput, P2 = pakan tambahan mengandung tepung dan minyak BSF + rumput. Parameter yang diuji adalah hemoglobin, hematokrit, eritrosit, leukosit, differensiasi leukosit (neutrofil, limfosit, monosit, eosinofil, dan basofil), glukosa, trigliserida, kolesterol, dan blood urea nitrogen. Data dianalisis dengan menggunakan T-Test (independent sample T-Test). Hasil penelitian menunjukkan bahwa perlakuan tidak memberikan pengaruh nyata (P>0,05) terhadap differensiasi leukosit (neutrofil, limfosit, monosit, eosinofil, dan basofil), glukosa, trigliserida, dan kolesterol. Perlakuan memberikan pengaruh nyata (P<0,05) terhadap hemoglobin, hematokrit, eritrosit, leukosit, dan blood urea nitrogen. Pakan tambahan yang mengandung tepung dan minyak BSF diberikan secara creep feeding dan tidak mengganggu profil darah ataupun status kesehatan ternak., This research was aimed to determine the feed additive containing BSF meal and BSF oil on blood profile in weaned lambs. This research used 10 post-weaning lambs. The lambs were divided into 2 treatments consisted of P1 = commercial ration + forage, P2 = feed additive containing BSF meal and BSF oil + forage. Parameters tested were the appearance of hemoglobin, hematocrite, red blood cells, white blood cells, leukocyte differentiation (neutrophils, lymphocytes, monocytes, eosinophils, and basophils), glucose, triglycerides, cholesterol, and blood urea nitrogen. The data were analyzed using T-Test (independent sample T-Test). The results showed that the treatment had no significant effect (P>0.05) on leukocyte differentiation (neutrophils, lymphocytes, monocytes, eosinophils, and basophils), glucose, triglycerides, and cholesterol. The treatment had a significant effect (P<0.05) on hemoglobin, hematocrite, red blood cells, white blood cells, and blood urea nitrogen. FBSF meal and BSF oil which is given by creep fedding and does not interfere with blood profile or health status of livestock.

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.
