Judul: Profil Lipid Darah, Omega-3, dan Omega-6 Daging Ayam Broiler yang Mengandung Minyak Ikan Lemuru dan Minyak Sawit dalam Ransum
Abstrak: Ayam broiler memiliki pertumbuhan cepat yang diiringi juga dengan pertumbuhan lemak. Kandungan lemak dalam karkas yang tinggi menjadi perhatian khusus bagi konsumen dan produsen ternak. Penelitian ini dilakukan untuk mengetahui pengaruh penambahan minyak ikan lemuru dan minyak sawit dalam ransum terhadap profil lemak darah, omega-3 dan omega-6 dalam daging ayam broiler. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan, yang masing-masing ulangan diisi 10 ekor broiler. Perlakuan terdiri dari P0 = ransum mengandung minyak sawit 3% + minyak ikan lemuru 0%, P1= ransum mengandung minyak sawit 2% + minyak ikan lemuru 1%, P2 = ransum mengandung minyak sawit 1% + minyak ikan lemuru 2% dan P3= ransum mengandung minyak sawit 0% + minyak ikan lemuru 3% . Data profil lipid darah, omega-3 dan omega-6 dianalisis dengan analisis ragam (ANOVA), hasil yang signifikan diuji lanjut dengan uji Duncan. Dilakukan analisis regresi kuadratik untuk mengetahui hubungan kolesterol darah dengan kolesterol daging broiler. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan yang nyata pada trigliserida, LDL, HDL, dan omega-6 antar perlakuannya tetapi berbeda nyata pada kadar omega-3 daging broiler. Pemberian minyak sawit dan minyak ikan lemuru sampai taraf 3% dalam ransum mampu meningkatkan kadar omega-3 dalam daging ayam broiler.

Judul: Pemberian Minyak Kelapa Sawit dan Minyak Ikan Lemuru dalam Ransum Terhadap Profil Darah dan Persentase Organ Dalam Ayam Broiler
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian minyak kelapa sawit dan minyak ikan lemuru terhadap profil darah dan persentase organ dalam ayam broiler. Penelitian ini menggunakan 200 ekor day old chick (DOC) broiler strain Ross yang dibagi dalam 4 perlakuan dan 5 ulangan. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan P0 = ransum mengandung minyak kelapa sawit 3% dan minyak ikan lemuru 0%, P1 = ransum mengandung minyak kelapa sawit 2% dan minyak ikan lemuru 1%, P2 = ransum mengandung minyak kelapa sawit 1% dan minyak ikan lemuru 2%, P3 = ransum mengandung minyak kelapa sawit 0% dan minyak ikan lemuru 3%. Data yang diperoleh dianalisis menggunakan analisis varians (Anova) dan dilakukan uji lanjut Duncan. Peubah yang diamati adalah profil darah, persentase bobot organ dalam, persentase bobot saluran pencernaan dan panjang relatif saluran pencernaan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0.05) terhadap jumlah hematokrit, eritrosit, leukosit, dan deferensiasi leukosit (monosit, eosinofil, basofil), persentase bobot jantung, ginjal, empedu, pankreas, bursa fabricius, thimus, proventrikulus, gizzard, panjang relatif duodenum, persentase bobot dan panjang relatif jejunum, ileum, sekum, serta kolon. Pemberian minyak ikan lemuru 3% berpengaruh nyata (P<0.05) meningkatkan nilai hemoglobin, diferensiasi leukosit (heterofil dan limfosit), persentase bobot hati, persentase bobot limfa, serta menurunkan persentase bobot duodenum dan nilai rasio H/L. Disimpulkan bahwa pemberian ransum mengandung minyak ikan lemuru 3% dalam ransum memberikan dampak positif terhadap profil darahm ayam broiler, dapat meningkatkan kadar hemoglobin, limfosit, dan menurunkan tingkat stress dari taraf tinggi ke taraf rendah., The purpose of this study was to evaluate the effect of giving palm oil and lemuru fish oil on the blood profile and the percentage of internal organs in broiler chickens. This study used 200 Ross broilers day old chick (DOC) is divided into 4 treatments and 5 replications. This research used a completely randomized design (CRD), where the treatments level of palm oil and lemuru fish oil were respectively P0 = rations containing 3% palm oil and 0% lemuru fish oil, P1 = rations containing 2% palm oil and 1% lemuru fish oil, P2 = rations containing 1% palm oil and 2% lemuru fish oil, P3 = rations containing 0% palm oil and 3% lemuru fish oil. The data obtained were analyzed using analysis of variance (Anova) and Duncan's further test was carried out. Some of the observed variables included blood profile, percentage of internal organ weight, percentage of digestive tract weight and relative length of digestive tract. The results showed that the treatment had no significant effect (P>0.05) on the number of hematocrits, erythrocytes, leukocytes, and leukocyte differentiation (monocytes, eosinophils, basophils), the percentage of weight of the heart, kidneys, bile, pancreas, bursa of Fabricius, thymus, proventiculus, gizzard, relative length of duodenum, percentage of weight and relative length of jejunum, ileum, cecum, and colon. Giving 3% lemuru fish oil significantly (P<0.05) increased hemoglobin value, leukocyte differentiation (heterophile and lymphocyte), liver weight percentage, spleen weight percentage, and decreased duodenal weight percentage and H/L ratio value. It was concluded that the provision of rations containing 3% lemuru fish oil in the ration had a positive impact

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.
