Judul: Analisis permintaan daging ayam broiler konsumen rumah tangga di Kecamatan Pamulang Tangerang
Abstrak: Kecamatan Pamulang is one of sub district existing in Kabupaten Tangerang. It has a huge sum of population as a residence with the consumption rate of meat base protein a number of 2.46 kg/ capitall year (Animal Husbandry Official of Kabupaten Tangerang, 2005). Kecamatan Pamulang has several supermarkets and traditional markets which supplies the broiler meat for the society needs. The objective of this study was to learn the factor influencing the total of demand and the large of broiler meat elasticity by the household consumer in Kecamatan Pamulang. This study is done on March to April 2006. The samples were taken by the multistage purposive sampling. It took a number of 60's family as sample. The design of study was a survey method. The data were analysed that used is the descriptive statistic, multiple linier regression and response analyses (elasticity). The result of study explaining that from the seventh variables were only four variables which real influential to the broiler meat demands by the household consumer, that is the broiler meat price, the beef price, the sum of family member and the favor level of dummy. Those fourth variables were real influential at real level a = 0.01. According to the demands elasticity conjecture result explain that the price elasticity (-2.164) and cross elasticity (10.241) has elastic characteristic. Keywords: Demand, Tie broiler meat, Elasticity.

Judul: Analisis permintaan daging ayam broiler konsumen rumah tangga di Kecamatan Pancoran Mas Kota Depok
Abstrak: The aims of this research were : 1) to know the factors which influencing the total demand of broiler by the household consumers in Kecamatan Pancoran Mas Kota Depok, 2) to know demand elasticity of broiler by household consumer in Kecamatan Pancoran Mas Kota Depok. This research was held on 18 August until 13 September 2007. Data was analyzed using the descriptive statistic, multiple linier regression and response analyses (elasticity). The result showed that factors which highly significant to the broiler demand by household consumers in Kecarnatan Pancoran Mas Kota Depok were the broiler price, the beef price, inc~met,h e sum of family member and the favor level of dummy. The demand elastic, ty of broiler by the household consvmers in Kecamatan Pancorm Mas Kota Depok has elastic characteristic (-2.355). The cross elasticity (6.32) showed that broiler and beef are subtitution goods. While income elasticity is (0.447). It shows that in the household consumers in Kecamatan Pancoran Mas Kota Depok, broiler is mainly good (nonnal goods)

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.
