Judul: Perbandingan Distribusi Otot Kambing Kacang dan Peranakan Etawah pada Bobot Lepas
Abstrak: A total of 43 goats which consist of 27 kacang goats and 16 peranakan etawah goatswas used to evaluate the comparison of muscle distribution between kacang goat and PE goat slaughtered over the weight 10 Kg. The data of body components was analyzed using Analysis of Variance (ANOVA) while muscle of distribution and other body components were analyzed using Analysis of Covariance (ANCOVA) with slaughter weight, half carcass weight as a covariable. The result showed that groups of muscles and body components among these breeds were no significantly different (P>0.05). There were no significantly differences among breeds in muscles of groups except the percentages of muscles of groups 3 and the muscles of groups 5. There were no significantly differences among breeds in body components except inter muscle fat weight, subcutan fat weight, inter muscle fat percentage, subcutan fat percentage, and kidney fat percentage. In general, the major muscles groups percentage (groups 1+3+5) in kacang goat is 60.35% and 60.71% for peranakan etawah goat.

Judul: Karakteristik Karkas dan Non Karkas Kambing Kacang dan Kambing Peranakan Etawah (PE) pada Bobot Lepas Sapih.
Abstrak: This study was conducted to evaluate carcass and non carcass characteristics of 27 Kacang goats and 16 Etawah crossbreed goats (Peranakan Etawah, PE) at post-weaning body weight (average 10.04 kg). The data were analysed using Analysis of Covariance (ANCOVA) with Slaughter Weight (SLW) and half carcass side as covariable. The results showed that PE goats had very significantly (P<0.01) higher in SLW, non carcass weight and percentages (based on SLW), while their Empty Body Weight (EBW) was significantly higher (P<0.05) than Kacang goats. PE goats had higher (P<0.01) percentages (based on EBW) of tail, vesica urinaria, and intestinal tract. PE goats also had higher (P<0.05) blood, pancreas and gastrointestinal tract percentages, whereas percentages of omental fat (P<0.05) and genitals (P<0.01) were greater for Kacang goats. There were no differences observed in percentages of muscle, fat and bone of carcass components between breeds, but PE goats had very significantly (P<0.01) higher percentages of connective tissue than Kacang goats. PE goats had higher proportion of leg (P<0.01), but Kacang goat had significantly higher (P<0.01) proportion of loin, rack and breast. Evaluation on carcass and non carcass characteristics of Kacang goats and PE goats which slaughtered at post-weaning body weight resulted differences on non carcass characteristics, carcass compositions and tissue distributions of commersial cuts.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
