Judul: Hubungan karakteristik peternak domba dengan kompetensi berusaha ternak domba
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: Kasus Peternak Domba di Kelurahan Cimahpar, Kecamatan Bogor Utara, Kota Bogor, Jawa Barat
Abstrak: Cimahpar’s Village represent one of a village in Bogor City which some of its society are sheep farmers. Motivation of sheep farmers is important aspect in livestock development. The research aims are needed the sheep farmer characteristics, motivational level of sheep farmers, and influencing of motivation level factors of sheep farmers in Cimahpar’s Village, Subdistrict of North Bogor, Bogor City, West Java. The research conducted on June-July 2005 at Cimahpar’s Village, Subdistrict of North Bogor, Bogor City, West Java. The total of sheep farmers as population are 390 farmers. Sample take by simple random sampling, totaly 63 farmers. The results indicated that the motivation of sheep farmers in Cimahpar’s Village categorized medium. It’s mean that sheep farmers in Cimahpar’s Village have motivation to manage sheep livestock, including to increase sheep productivity. Those motivation influencing by age, number of family members, education and knowledge of market information. This research recommended as follow. Sheep farmer need facilitate to build group farmer sheep that orientate to increase sheep farmer economic condition. The institute expected able to assist the sheep farmer in marketing and on farm aspect, including livestock produce accomplishment. All the activity will be more succeed if followed with the activity of empowerment of sheep farmer.

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.
