Judul: Pengaruh Bangsa Domba dengan Bobot Potong yang Berbeda terhadap Karakteristik Karkas dan Non Karkas Domba Lokal
Abstrak: Carcass and non carcass characteristics were evaluated in 66 local ewe consisting of 25 Thin tailed sheep (DET), 23 Tail fat sheep (DEG) and 18 Garut sheep (DG). The research was designed using Completly Randomized Design (RAL), 3x3 factorial pattern, with two different factors, among three local ewe (Thin Tail Sheep, Fat Tail Sheep, and Garut Sheep) with three categories of slaughter weights, first category (6-14 kg), second category (15-23 kg) and third category (≥24 kg). The data were analyzed using analizes of varians (ANOVA) and the different among treatmen’s were tested by LS Means. The result showed that carcass percentage only were significantly (P<0.05) influenced by the interaction of breed and slaughter weight category of local ewe. The result showed the largest percentage of carcass was obtained from fat tailed sheep in the second slaughter category (48.84%), and the smallest carcass percentage occured in garut sheep of the second slaughter category (42.63%).

Judul: Karakteristik Karkas dan Non Karkas Domba Lokal Betina yang Berbeda Bangsa di TPH Maleber Bogor
Abstrak: A total of 119 local ewe which consist of 18, 76 and 25 garut sheep, thintailed sheep and fat-tailed sheep was used to evaluate the characteristics of carcass and non carcass at slaughterhouse in Maleber Bogor. The data were analyzed using Analysis of Covariance (ANCOVA), with slaughter weight as a covariable. The results showed that slaughter weight, carcass weight, empty body weight and carcass percentage among these breeds were no significantly different (P>0.05). There were no significantly differences among breeds in the weights of non carcass components, except kidney and shank. There were no significantly among breeds differences in percentage of non carcass components, except kidney percentage. In general, the garut sheep, thin-tailed and fat-tailed slaughtered at weight 20.46 kg, 15.73 kg and 15.98 kg had carcass percentages of 47.14%, 46.61% and 47.65%, and non carcass percentages of 33.56%, 32.73% and 33.32% respectively

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.
