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: 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.
