Judul: Beberapa faktor yang mempengaruhi produksi dan penawaran daging, susu, dan telur di Jawa Barat dan Lampung
Abstrak: This study was prepared due to the essential role of meat, milk, and egg as nutritions food to increase the standard of living. for these commodities. There was an increasing demand However there is a slow rate of increase, if not decrease, of the livestock population as the source of these commodities. The purpose of this study was to identify variables at the farmers level affecting the production and supply of meat, fresh milk, and fresh egg, in the light of the possibility of developing livestock production. The survey was conducted at the Province of West Java and Lampung, for the two regions reveal some differences with respect to the prospect of livestock development. By comparing these two regions, it is expected that the result will give some ideas in formulating live- stock development policy not only for the two regions, but also for other regions in Indonesia. Regression analysis of production and supply of meat does not tell us much, for the independent variables could a not explain the production and supply (R2 less than 0.20). Nevertheless, data indicated that on the average a Farmer owns only 2.7 buffaloes in west Java and 4.6 buffaloes and 2.7 cattle in Lampung. Only 17 percent of farmer In West Java sold any Of their cattle within the year proceding the data of enumeration and only 23 percent in Lampung (Table 4.14). Most of the sales are consumptive , (95 percent) such as for housing, education expenses, ritual ceremonies. From the supply point Of view, the amount and frequency OF sales were relatively smal1. Supply elasticity meat to price was 1.14566 for buffalo and 1.05049 for cattle. There was on indication that time variable has some influence On supply of meat. For instance, more cows and buffaloes are slaughtered in the month of lebaran and new year. Elasticity of milk supply to the amount of dairy cow was 0.645 to productivity 0.93892, and to ratio of milk price to dedak price 0.13874. Elasticity of ego Supply to the amount of layers was 1.06881 and to productivity of layers is 0.9643. was Judging from the results explained above, evident that the farmers have little variables selling their livestock. On the other hand due to the high elasticities at slaughtering agent, (pejagal), it could be concluded that butchers have a strong bargaining position in livestock marketing. dst. ...

Judul: Production efficiency analysis of dairy farm in pondok ranggon cipayung sub-district east jakarta
Abstrak: Permintaan susu sapi perah di Indonesia meningkat setiap tahunnya, namun produksinya belum memenuhi kebutuhan nasional. Peternakan sapi perah Pondok Ranggon merupakan tempat penyedia susu sapi untuk warga DKI Jakarta. Peternakan sapi perah Pondok Ranggon memiliki peranan penting dalam peningkatan produksi susu di Indonesia. Tujuan penelitian ini adalah untuk: (1) menganalisis faktor-faktor yang mempengaruhi produksi susu sapi perah, (2) menganalisis efisiensi produksi susu sapi perah, (3) menganalisis pendapatan usaha peternakan sapi perah di Pondok Ranggon. Faktor produksi susu sapi perah dianalisis menggunakan fungsi produksi Cobb-Douglas dan parameter diestimasi dengan metode Ordinary Least Squares (OLS), analisis efisiensi produksi dilakukan dengan menggunakan Nilai Produk Marginal (NPM) sama dengan harga faktor produksi, dan pendapatan usaha peternakan dilakukan dengan analisis pendapatan. Faktor-faktor yang mempengaruhi produksi susu sapi perah adalah pakan hijauan, ampas tahu, dan tenaga kerja. Nilai efisiensi masing-masing faktor produksi tidak sama dengan satu, berarti bahwa penggunanaan faktor produksi belum efisien. Nilai R/C ratio yang lebih besar dari satu, sehingga analisis pendapatan menunjukkan bahwa usaha peternakan sapi perah menguntungkan., The demand for milk of dairy cattle in Indonesia increasing every year, but the production has not fulfill the national needs. Pondok Ranggon dairy farm is a supplier milk to DKI Jakarta people. Pondok Ranggon dairy farm has an important role in improvement milk production in Indonesia. The purposes of the study were to: (1) analyze the affecting factors for the production milk of dairy cattle, (2) analyze the production efficiency of milk of dairy cattle, (3) analyze the income of Pondok Ranggon dairy farm. The production factor of milk of dairy cattle was using the production function of Cobb-Douglas analysis and estimated parameter was using Ordinary Least Squares (OLS) method, analysis production efficiency was using Value of Marginal Product (VMP) equal to production factor prices, and income of dairy farm analyze using income analysis. The affecting factors of production milk of dairy cattle is grass, tofu waste, and labors. The value of efficiency of each production factor is not equal to one, means that the use of production function have not been efficient. The value of R/C ratio is greater than one, so that the income analysis shows for dairy farm is profitable.

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.
