Abstrak: The objectives of this study were: I) to dcscribe the characteristic and external factors of sheep farmers at Barengkok village 2) to anal competency of sheep farmers at Barengkok village 3) to analyze correlation between characteristic and external factors of sheep farmers at Barengkok village. This study was conducted on Juni 2008 at Barengkok village. The amount of respondent was 60 farmers at Barengkok village. Primary data was obtained by of questionnaire and interview. Secondary data was obtained from relevant institutions sources. Data were analyzed by descriptive analyze and correlation analyze using rank Spearman and Chi square test. The result of study showed: 1) most farmers were young, less educated, have experience about having livestock are few, ownership of livestock are few, level of medium earning. Most farmers were never frequency of farmers in getting information about sheep farming operation, both newspaper, magazine, radio and television. Sheep farmer never makes interpersonal relation by people who provides elucidation but peer of the farmers. 2) technical competency and management competency of sheep farmer were few but technical competency of sheep farmer better than management competency of sheep farmer. 3) sheep farmers characteristics has high significant correlation at the education of farmers and income of farmers with technical competency and management competency of sheep farmers. Frequency of reading newspaper by farmers and interpersonal relation by other farmers has significant with technical competency

Judul: Profil Peternakan Domba Rakyat di Desa Cibanteng dan Desa Cikarawang.
Abstrak: Traditional farmers have good experience in sheep farming but they still have weakness in management, especially in financial aspects in measuring business profit and loss. This research was purposed to explaining general condition and examinating financial aspect of sheep traditional farm in two villages Cibanteng and Cikarawang. Thirty farmer respondents from each village were interviewed, and clasified into two categories (scale I and scale II) based on average number of sheep. Data were analyzed by description method. The result showed that average of farmer’s cash revenue in Cibanteng Village were Rp 4 894 737 per year (scale I) and Rp 9 000 000 per year (scale II); average of farmer’s cash revenue in Cikarawang Village were Rp 3 642 857 per year (scale I) and Rp 8 000 000 per year (scale II). Although they had got profit by cash revenue, actually they was in loss condition and not productive yet, shown by number of sale <BEP (Break Event Point) and Revenue and Cost ratio (R/C) <1. However they continued to raise sheep by traditional method because there are many production factors that have never calculated (non-cash of cost production) so that was still a profitable farm activity. By assumption of potential production coefficient, 77 sheep must be sold per year to made equivalent profit with Bogor regional minimum wage by maintaining 38 ewes at the beginning of year and supported by implementation of good farming practices (GFP).

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.
