Abstrak: The observation has purpose (1)To analize the influence of the price meat import meat (2) To analize the influence of riel value (3) To analize the influence of offering domestic meat (4) To Analize the influence of consumption domestic meat (5) To analize the influence of income. The obervation held first month of June untill last month of June 2008 the data which used secondary from Badan Pusat Statistik. The observation analized by quantitatif description to describe variable offering meat import and qualitatif by Cobb Douglas model which linier double log transformation which used Microsoft Excel and software Eviews 4.1. The result of this observation are (1) the amount of R2 Value is 96,43% it's mean the variation of variable can be explained like liniear by the variable free. (2) On test F shown 0,00001 which has value more litle than rate of real which used is a=5% it means the value shown that the similarity significant enough to explain the variable which used. (3) the amount elastisity shown degree of feeling variable dependent on similarity to changing of variable independent (4) In test of econometrics the similarity have not problem auto corelation heteroskedastisity and multikolinieritas (5) The variables which have negative influence to meat import requirement is value riel changing the price of meat import, and meat domestic offering (6) The variables which have positive influence to meat cow import is meat consumption and income per capity of people

Judul: Analisis Faktor-faktor yang Memengaruhi Permintaan Daging Sapi dan Implikasinya terhadap Kebijakan Impor
Abstrak: Chaotic imported beef in November 2012, resulting in a rise in the price of beef in the market so that the need for special handling so that beef prices. This research was conducted to analyze the factors that affect the demand for beef in Indonesia and the role of substitution, and the implications of policy import. This study uses secondary data the period 1982-2011. Analyses were performed with the econometric approach, estimation models using Principal Component Regression (RKU). The results show the coefficient of determination (R2) of 71.7 percent, and the elasticity of each of the variables tested small relative to the demand for beef show that beef consumption is not replaceable. Beef demand continues to increase every year even though the price of beef is relatively expensive. Formulations stabilization policy covering the prices of additional supplies at the time of the great religious, imports done merely to meet national shortage of supplies beef and ensure the availability of food -substitutions beef as the availability of chicken meat and eggs, and increases the production of beef in the long run.

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.
