Judul: Study of phenotypics and genetics diversity of some indonesian local goat sub populations and its strategies for sustainable use
Abstrak: The genetic resources of local goats are very important because it was well adapted to the local environment with low input management systems. Local goats are very potential for breeding stock program which suitable to the Indonesia local conditions. The study was carried out in order to describe the phenotypic and genetic of 6 sub-populations of Indonesian local goats based on the analysis of the morphometrics, mitochondrial DNA, Y Chromosome and GDF9 gene. The sampling was conducted in four of the Provinces in Indonesia, namely North Sumatra Province (Samosir goat n=42 in the Samosir District, Muara goat n=34 in the North Tapanuli district, Kacang goat n=217 in the Deli Serdang District), Central Java Province (Jawarandu goat n=94 in the Blora District); Province of South Sulawesi (Marica goat n=60 in the Maros District, Makassar City, Jeneponto District) and Nusa Tenggara Timur Province (Bengala goat n=96 in the Kupang area, Sikka District, Ende District). All of them were measured for morphometric and was bleeding to collect blood as DNA sources. The blood sample was preserve with absolute ethanol. DNA extracted was analyzed by PCR-RFLP methods for D-loop region, SRY gene and GDF gene on Indonesian local goat does.

Abstrak: The increasing of Indonesian local sheep productivity can be done by one of the effort that are selection and crossing. The effectively of selection activity will be done in certain characteristic is in a various condition. The aim of this study was to identify the variants of k-casein and β-lactoglobulin gene in the Indonesian local sheep.

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.
