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: Karakteristik karkas dan non karkas Domba Lokal betina yang berbeda bangsa di TPH Maleber Bogor
Abstrak: Sebanyak 119 ekor domba lokal betina yang terdiri dari 18, 76 dan 25 ekor domba garut (DG), domba ekor tipis (DET) dan domba ekor gemuk (DEG) digunakan untuk mengevaluasi karakteristik karkas dan non karkas di tempat potong hewan (TPH) di Maleber bogor. Data karkas dan non karkas dianalisis menggunakan Analysis of Covariance (ANCOVA). Bobot potong domba sebagai covariable. Hasil penelitian menunjukkan bahwa bobot potong, bobot karkas. bobot tubuh kosong dan persentase karkas antarbangsa tersebut tidak berbeda nyata (P>0.05). Tidak ada perbedaan signifikan antar bangsa dalam komponen bobot bobot non karkas, kecuali ginjal dan kaki. Tidak terdapat perbedaan yang signifikan antar bangsa dalam persentase komponen non karkas, kecuali persentase ginjal. Secara umum, DG, DET dan DEG yang disembelih pada bobot potong 20.46 kg. 15.67 kg dan 15.98 kg menghasilkan masing-masing persentase karkas 46.62%, 46.77% dan 47.71%, dan persentase non karkas 33.56%, 32.73% dan 33.32%.

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.
