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: 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.
