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: 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.
