Judul: Evaluasi beberapa ransum komersil terhadap persentase bobot karkas, lemak abdomen dan organ dalam ayam broiler
Abstrak: This research was carried out to study the effect of feeding 4 commercial chicken diets on carcass, abdominal fat and viscera of broilerc hicken. Fourty of broilers strain X from 200 Daya Old Chick which were kept in litter system during five weeks were observed in this experiment.This research used Completely Randomize Design consisted of 4 treatments and 5 replications.

Judul: Evaluasi Penggunaan Tepung Garut, Tepung Ubi Jalar dan Onggok sebagai Perekat Pellet Terhadap Persentase Bobot Karkas, Lemak Abdomen dan Organ Dalam Ayam Broiler
Abstrak: Penelitian dilakukan untuk mengevaluasi penggunaan tepung garut, ubi jalar dan onggok sebagai perekat pellet terhadap persentase bobot karkas, lemak abdomen dan organ dalam ayam broiler. Penelitian ini menggunakan 32 ekor ayam broiler dari 240 ekor Day Old Chick yang dipelihara dalam kandang litter selama lima minggu. Analisis data menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan. Perlakuan yang diberikan yaitu: A1 = pakan basal, A2 : A1 + 2% tepung garut, A3 : A1 + 2% tepung ubi jalar dan A4 : A1 + 2% onggok. Hasil penelitian menunjukkan bahwa penggunaan tepung garut, tepung ubi jalar dan onggok tidak mempengaruhi berat karkas, organ dalam dan lemak abdomen ayam broiler. Rata-rata persentase berat karkas, lemak abdomen, jantung, hati dan rempela pada penelitian ini adalah 64.03%-64.41%, 0.87%-1.14%. 0.58%-0.61%, 2.52%-2.79%, 2.09%-2.20%. Berdasarkan hasil penelitian dapat disimpulkan bahwa perlakuan tidak memberikan pengaruh pada persentase berat karkas, lemak abdomen dan organ dalam ayam broiler.

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.
