Judul: Analisis wilayah pengembangan komoditas peternakan di Provinsi Riau
Abstrak: The development of livestock potential is expected to reduce of production and market unbalances. Knowing patterns of marketing of livestock commodities inter-regions may increase some added value of commodities. The purposes this research are: 1) to analyze the potential of livestock commodities in the public lands in Riau province, 2) to analyze flow of livestock commodities marketing inter-region in Riau Province, 3) to analyze trade order (price, marketing margins, and institutional) of livestock commodities in Riau Province, 4) to arrange direction of livestock commodities development based marketing potential, 5) to arrangement livestock development strategy Riau Province. Analysis for regional carrying capacity was based on the availability of forage; analysis for marketing flow of livestock commodities used the gravity model analysis and entropy interaction model with doubly constrained; analysis of trading system employed margin trading system analysis; hierarchy analysis used scalogram method; and spatial analysis used geographic information system applications.

Judul: An analysis of prime agricultural comodities and their development strategy In Ciamis Regency, West Java Province;
Abstrak: The regional development in the regional autonomy era requires development of regional potential inside the region itself (local development) which is prioritized to the commodities development. The aims of the study is to analyze the prime agriculture commodities and how to formulate their development strategy. The research was conducted in Ciamis Regency, west Java Province March to July 2011. The analysed data is input-output table of Ciamis regency year 2008. To determine prime agriculture commodities analyze with backward and forward linkage, backward and forward dispersion as well as output, income and employment multiplier. The development strategy was formulated using combination of two analyse; those are the AHP and SWOT analyse (A-WOT). The results show that the prime agriculture commodities in Ciamis regency are rice product with index composite value around 0.75, chicken meat product with index composite value around 0.68 and cow with index composite value 0.67. Development strategies for the three prime agriculture commodities are as follow: increasing quantity and quality rice production; capital assistance for local economic actors (poultry shop and breeding farm); increasing cow population through revolving fund and insemination program.

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.
