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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
