Judul: Evaluasi Aspek Teknis dan Strategi Pengembangan Sapi Perah Rakyat di Kabupaten Karo Sumatera Utara
Abstrak: Animal husbandry of dairy cattle is one effort in the field of a farm that has strategic role in meet the needs of food. The development of dairy cattle encourages the creation of animal husbandry is sustained. One of the areas animal husbandry of dairy cattle the people in North Sumatera are Karo District which until now are still experiencing stagnation. The Central Bureau of Statistics Karo year 2014 noted the population of dairy cattle years 2009-2011 down by 35.46%. In the 2012-2013 back increased by 29.07% of the population of 2011 but in general the data the last five years showed that the decrease in the population as much as 16.70%. A trend of decreasing is greatly affected by the condition of management and environment. Farm productivity of dairy cattle the people low was also affected the environment of the internal and external research so that aims for the evaluation of the technical aspects of animal husbandry and animal husbandry development strategy of dairy cattle the people according to the principle of good dairy farming practices (GDFP). The method used is the survey. The sample collection farmers use the survey respondents with a total of sampling as many as 18 peoples. The use of expert respondents research aimed to obtain relevant information in the preparation of the strategy the development of dairy cattle the people. The determination of purposively sampling done as many as 4 peoples. Data processing using chi-square test the results of research . The preparation of strategies carried out by classifying two enviroment factors which is external factors and internal analysis and training. The result showed the value of GDFP highest on the management aspects of as much as 3.05 (good category) and the lowest is at the health aspect of livestock 1.52 (category less good). The total score weights the internal environment factor of 2.502 the score and the total weight of the external environment factor 2.525. The position of internal external matrix be on a cell 5 shows the development of animal husbandry of dairy cattle the people who fit in karo district use strategy growth through horizontal integration.

Judul: Strategi Pengembangan Usahaternak Sapi Perah di Kecamatan Sukaresmi, Kabupaten Cianjur, Jawa Barat
Abstrak: The goals of this research were : 1) to identify internal and external environmental factors which can influences the progress of dairy cattle business, 2) to formulate alternative development strategy and to decide the priority development strategy of dairy cattle business in Sukaresmi, SubDistrict of Cianjur. This research was carried out from Desember 2008 to January 2009. This research used primary dan secondary data. The data was analysed with descriptive analysis and three stages formulating analysis (input stage, matching stage, and decision stage). The result of input stage analysis show that total IFE matrix score is 2,615 and total EFE matrix score is 3,164. This condition place dairy cattle business in Sukaresmi, SubDistrict of Cianjur on sel II (Grow and Build) at matrix InternalExternal (IE). While, SWOT analysis produce five alternatives development strategy, which then analyzed by matrix QSP to decide the priority of the development strategy. Based on matrix QSP, the priority development strategy of dairy cattle business in Sukaresmi, SubDistrict of Cianjur is increase the business scale, develope the product diversification in farmer level, increase capital resources, improve dairy cattle management, and strengthen the function of farmer group.

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.
