Abstrak: The number of milk consumption 12.50 Ls capita-1 year-1 have not been able to be met through national milk production. Deficit in milk production opportunities for dairy goat farmers to develop the business. Livestock development resulting externalities. According to Pindyck, Robert and Rubinfeld (2007) An externality is an activity either by perodusen or consumers that can affect producers and other consumers, but not factored into the cost of the market. Indirectly these impacts will be considered for the development of dairy goat farming business, so the need for studies on the impact of positive and negative externalities caused by the presence of dairy goat farm. The purpose of this study was to analyze the impact of dairy goat farm externalities on people's lives around. The experiment was conducted at Wake Karso dairy goat farm. The population in this study is the community living around the dairy goat farm. Sampling method used was purposive sampling. This study uses 70 respondents who dwelt at a distance of 0 to 1 km from dairy goat farms. The results showed that the majority of people (57.32%) expressed disagreement to the positive externalities generated and the majority of people (90.20%) expressed disagreement to the negative externalities caused. Positive externalities not provide a real benefit to society and the negative impacts are not felt by the public, so the public is not compromised states due to dairy goat farm.

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: 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.
