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: Komposisi dan Distribusi Otot Kambing Kacang dan Kambing Peranakan Etawah yang Dipotong pada Bobot Sedang.
Abstrak: A total of 36 goats which consist of 26 kacang goats and 10 peranakan etawah goats were used to evaluate the muscle composition and distribution slaughtered in medium body weight (16.49 kg). Compositition of carcass in slaugter weight, carcass weight and a half weight carcass kacang goats were significantly different (P<0.01) than PE goats. The expensive muscle group (1+3+5) were 52.15% of carcasses muscle of kacang goats and 51.47% of carcassses muscle of peranakan etawah goats. The other muscle group 2, 4, 6, 7, 8 and 9 were 4.75, 12.02, 3.82, 3.20, 7.22 and 16.76% of kacang goats 5.34, 12.56, 4.07, 3.06, 7.11 and 16.42% peranakan etawah goats. The weight of group 1 (proximal thigh) on kacang goats was heavier than PE goats. Percentage of all weight in both breed goats have relatively equal proportions except group 2 that was percentage distal thigh muscle PE goats was larger than kacang goats at the medium slaughter 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.
