Judul: Hubungan karakteristik dan sikap anggota terhadap keberadaan kelompok tani ternak (studi kasus pada kelompok tani ternak domba makori di Kecamatan Jasinga Kabupaten Bogor)
Abstrak: The aim of the research was to study the group attitude toward existence of group livestock in Kecamatan Jasinga Kabupaten Bogor. The research samples were 20 farmers. The technique sampling was census sampling. Analyzing data was using the statistics of descriptive which are: frequency, percentage, and analyze of Rank Spearman. The conclusion of Rank Spearman results was regard to relationship between internal factor and external factor with the attitude of member of the group. The attitude member for the existence of the group with all aspect was classified middle category. Internal factor influencing attitude of member to existence of group of livestock is age, education, scale is effort and mount knowledge. Age related to attitude of member to activity. Education related to total attitude. Scale is effort relating to total of attitude. Mount knowledge related to total attitude. Factor of External entirely have an relation with attitude of member to existence of livestock group.

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.
