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: Analisis Faktor-Faktor yang Mempengaruhi Jumlah Permintaan Konsumen Keluarga Terhadap Daging Sapi di Kotamadya Bogor, Jawa Barat
Abstrak: Sejalan dengan tujuan pemerintah dalam memenuhi kebutuhan masyarakat akan protein hewani maka peningkatan jumlah konsumsi protein hewani harus disertai pula dengan peningkatan produktivitas ternaknya. Salah satu ternak yang paling banyak menyumbangkan daging untuk memenuhi konsumsi protein hewani adalah ternak sapi. Tujuan penelitian adalah untuk mempelajari faktor-faktor yang mempengaruhi permintaan dan untuk mengetahui besar pengaruh faktor-faktor tersebut terhadap permintaan daging sapi oleh konsumen keluarga. Penelitian ini dilakukan di Kotamadya Bogor, Jawa Barat mulai tanggal 18 Agustus sampai dengan 28 September 1989. Penelitian dilakukan dengan menggunakan metode survey pada konsumen keluarga. Jumlah sampel adalah 43 rumah tangga yang semuanya merupakan ibu rumah tangga. Pengambilan sampel dilakukan dengan cara acak sederhana. Data di lapangan diperoleh dengan wawancara langsung dengan menggunakan daftar isian, sedangkan data penunjang diperoleh dari instansi atau lembaga yang terkait. Untuk mengetahui pengaruh tingkat pendapatan keluarga, harga daging sapi, harga barang substitusi, tingkat pendidikan penentu konsumsi, jumlah anggota keluarga dan selera terhadap daging sapi pada konsumen keluarga dipakai analisis regresi model Cobb-Douglas dan model Linier. Hasil penelitian dengan model Cobb-Douglas menunjukkan bahwa tingkat pendapatan keluarga dan harga barang substitusi sangat nyata (p<0.01) berpengaruh terhadap permintaan daging sapi oleh konsumen keluarga. Faktor harga daging sapi, tingkat pendidikan penentu konsumsi, jumlah anggota keluarga dan selera tidak berpengaruh nyata terhadap permintaan daging sapi.

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.
