Judul: Faktor-faktor pendukung dan penghambat pengembangan usaha ternak sapi perah (studi kasus di Kelurahan Kebon Pedes Kecamatan tanah Sareal Kota Bogor)
Abstrak: Dairy farms have a high opportunity to be developed, but the farmers faced constraint those can be threat the sustainability of the dairy farms. During 1999- 2003, the average milk consumption per capita in Indonesia increased as much as 1.05% per year. A case study was carried out to understand the supporting and constraint factors for dairy farms development in Kebon Pedes, Bogor during May to June 2005. Thirty farmers by census and 30 people live around the farm by purposive were used as sample. Descriptive analysis, financial and milk demand forecast were used to analyze data. The farmer's average income per year was Rp 30,465,334.16 and R/C ratio was 1.93. It indicated that the dairy farm in Kebon Pedes was feasible. The supporting factors for dairy farm's development in Kebon Pedes were farmer knowledge, milk price, financial, institution, dairy cattle populatio~i and demand of milk in Bogor, which increase every year. The constraint factors are climate, land, and the environment pollution.

Judul: Analisis Keuntungan Usahaternak Sapi Perah (Kasus di Kelurahan Kebon Pedes, Kota Bogor
Abstrak: Indonesia’s milk production in 2012 equal 959.732 litre. Most of dairy cattle farmers in Indonesia run their business in small and medium scale. Productivity of dairy milk is closely related to the location of the farm. One of the location dairy farm in Bogor city is in Kebon Pedes sub-district. Dairy farm activities in Kebon Pedes sub-district been going on for decades. This area has an average temperature of 36o – 40o C and the unavailability of land as source of green feed making dairy milk productivity is not good. The results of this research showed milk productivity average by 10,51 litres per day. Cost of concentrate feed contributed the highest percentage of the total costs that equals to 49,33% of the total cost. Profit of dairy farm average by Rp.2.296,30 per litre and R/C ratio obtained 1,39. Feed cost factor and health cost factor significantly affect profitability of dairy farm business.

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.
