Judul: Analisis Pola Konsumsi Mahasiswa Terhadap Pangan Asal Ternak (Studi Kasus: Mahasiswa Program Sarjana Fakultas Ekonomi dan Manajemen Institut Pertanian Bogor Tahun Masuk 2010)
Abstrak: FEM Students have a diverse characteristic, which rise to differences in consumption decisions, one of which is the consumption of the food from livestock. This study aims to analyze the consumption pattern of the food from livestock, identify the factors that influence the demand for the food from livestock, and analyze the level of price and income elasticity of the food from livestock with the application of the Almost Ideal Demand System (AIDS) model. The results of this studies showed that the higher the students income, the lower the total expenditure of FEM students allocated to consumption of food from livestock. The largest proportion of total expenditure of FEM students is used for the consumption of chicken meat, followed by cow’s milk, eggs of chicken, and beef. The own price variable, cross-price, total expenditure, gender, residence status tends to be dominant significantly affect the proportion of food from livestock expenditure on the real level (α) of 0,10. The own price elasticity of beef, chicken meat, and eggs is inelastic while the own price elasticity of cow’s milk is elastic. Most of cross-price elasticity have negative sign, its mean that the livestock has the complementary relationship with other food from livestock. The income elasticity for chicken meat, and eggs of chicken shown the value less than one, its mean that commodities are a staple goods. The income elasticity for beef and cow’s milk shown the value more than one, its mean that commodity is considered luxury good

Judul: Dampak Kenaikan Harga Daging Sapi terhadap Pola Konsumsi Pangan Sumber Protein Hewani di Kabupaten Bogor.
Abstrak: One kind of food which has important role in developing the food security and create human resources who has healthy quality is food animal proteins. The government is targeting food consumption of animal protein as much as 7.2 g/capita/ day in 2014. Food sources of animal protein can be derived from livestock or fishery products like ruminant meat, poultry, fish, eggs, and milk. This study aims to analyze the pattern of household consumption in Bogor Regency, analyze the level of demand elasticity, and perform simulations to analyze the impact of higher prices for meat. The data used comes from SUSENAS 2012 with 1125 households in Bogor Regency. The analytical method used was descriptive analysis and model of Almost Ideal Demand System (AIDS). The analysis showed that the type of ruminant meat consumption group was very inelastic and have a lower level of consumption than other animal protein foods. People in Bogor Regency consume more fish than ruminant meat. Increasing the prices of beef could make other public consumption for food source of animal proteins is down. Food protein consumption for the people of Bogor regency have met the target set by the government

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.
