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: Karakteristik Karkas dan Non Karkas Domba Ekor Tipis Betina dengan Bobot Potong yang Berbeda di TPH Maleber Bogor
Abstrak: The purpose of the research was to evaluate the characteristics of carcass and non carcass of thin-tailed sheep (DET) on different live weight in TPH Maleber, West Java. Research used 56 heads of DET ewes. The sheep grouped into live weights at 10 kg, 20 kg and 30 kg. Data were analyzed by Analysis of Variance (ANOVA). The result of the research showed that the differences of live weight were significantly (P<0.01) influenced on empty body weight and carcass weight. DET that were slaughtered at 30 kg was heavier on carcass percentage compared to 20 kg. The average percentage of carcass at live weight 10 kg, 20 kg and 30 kg was 46.09%, 42.87% and 49.56% respectively. Non carcass components of DET were slaughtered at 30 kg was significant (P<0.01) heavier than live weight of 20 and 10 kg. The percentage of edible portion of non carcass was of 42%-48% of empty body weight.

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.
