Judul: GDFP and GMiP on Dairy Cattle Farms on a Scale of 10 Heads Dairy Cows Lactation in the Farm Business Area of Bogor Dictrict
Abstrak: Sapi perah merupakan sapi penghasil susu. Sapi perah yang banyak dijumpai di Indonesia merupakan sapi perah bangsa Friesian Holstein (FH). Keberhasilan dalam beternak sapi perah erat kaitannya dengan manajemen pemeliharaan juga manajemen pemerahan yang dilakukan oleh peternak. Penelitian ini mengethaui penerapan Good Dairy Farming Practice (GDFP) dan Good Milking Practice (GMiP) di Kawasana Usaha Peternakan (KUNAK) Kabupaten Bogor. Penerapan GDFP meliputi aspek pembibitan dan reproduksi, pakan dan air minum, pengelolaan, kandang dan peralatan, kesehatan ternak serta aspek kesejahteraan ternak. Penerapan GMiP meliputi aspek sebelum, saat, setelah pemerahan. Penelitian dilakukan dengan mewawancarai 30 peternak dalam 14 peternakan dengan populasi sapi perah 10 ekor betina laktasi. Data dianalisis deskriptif dan disimpulkan sesuai poin-poin yang telah diberi skor 4,3,2,1,0. Aspek GDFP yang sudah diterapkan dengan baik yaitu aspek pembibitan dan repoduksi, manajemen pakan dan air minum serta kesejahteraan hewan. Aspek GMiP yang sudah diterapkan cukup baik yaitu pada proses sebelum dan setelah pemerahan. Rata-rata produksi susu di peternakan KUNAK Kabupaten Bogor sebesar 10,9 L., Dairy cows are cows that produce milk. Friesian Holstein (FH) is on of the dairy cows that are found in Indonesia. Success in raising dairy cows is closely related to husbandry and milking management conducted by farmers. This study evaluated the application of Good Dairy Farming Practice (GDFP) and Good Milking Practice (GMiP) in the Farm Business Area of Bogor District. GDFP implementation includes aspects of breeding and reproduction, feed and drinking water management, management, housing and equipment, animal health also animal welfare. GMiP implementation includes before, during, and after milking. The study was conducted by interviewing 30 farmers in 14 farms with a population of 10 heads lactating dairy cows. Data were analyzed descriptively and summarized accordance of points that have been given a score of 4,3,2,1,0. GDFP aspects that have been implemented well that aspects of breeding and reproduction, aspects of feed and drinking water management, and aspect of animal welfare. GMiP aspects that have been implemented is good enough in the process before and after milking. Milk production averge in KUNAK farm of Bogor District was 10,9 L.

Judul: Application of GDFP and GMiP on Smallholder Dairy Farms in Tajurhalang Village Cijeruk Sub-district Bogor District West Java
Abstrak: Produksi susu di Indonesia hanya mampu memenuhi sekitar 22% dari kebutuhan susu nasional sedangkan sisanya berasal dari impor. Susu berkualitas baik dan aman dikonsumsi diproduksi dari peternakan yang mengaplikasikan manajemen pemerahan dan manajemen sanitasi yang baik. Good Dairy Farming Practice (GDFP) merupakan pedoman budidaya ternak sapi perah yang bertujuan untuk meningkatkan produktivitas suatu usaha peternakan sapi perah. Penerapan Good Milking Practice (GMiP) pada peternakan dapat menciptakan proses pemerahan yang higienis. Penelitian ini bertujuan mengetahui penerapan GDFP dan GMiP di Peternakan rakyat sapi perah di Desa Tajurhalang, Kecamatan Cijeruk, Kabupaten Bogor, Jawa Barat. Jumlah responden yang diwawancarai sebanyak 38 peternak. Data dianalisis menggunakan analisis deskriptif untuk mendeskripsikan kondisi peternakan sapi perah rakyat di Desa Tajurhalang. Hasil evaluasi penerapan GDFP di Desa Tajurhalang menunjukkan nilai rataan 3,47 (baik) dan hasil evaluasi penerapan GMiP menunjukkan nilai rataan 2,92 (cukup baik). Produksi susu rata- rata di Desa Tajurhalang yaitu sekitar 10,51 Liter ekor-1 hari-1. Perlu adanya peningkatan pada beberapa aspek agar nilai GDFP dan GMiP meningkat., Milk production level in Indonesia only able to fulfill approximately 22% of national milk needs while the rest are imported. Good quality and safe to consume milks are produced by farms that apply good milking management and good sanitation. Good Dairy Farming Practice (GDFP) is a guideline for dairy farming which aims to increase productivity of dairy farming business. Application of Good Milking Practice (GMiP) on farm can create hygienic milking process. The purpose of this research is to evaluate the application of GDFP and GMiP on smallholder dairy farms in Tajurhalang Village, Cijeruk Sub-district, Bogor District, West Java. The number of respondents that has been interviewed are 38 farmer. The data were analyzed using descriptive analysis to describe the condition of smallholder dairy farms in Tajurhalang Village. The result of the evaluation of GDFP in Tajurhalang Village show an average value of 3,47 (good) and the evaluation of GMiP show an average value of 2,92 (good enough). Average milk production in Tajurhalang Village is ±10,51 Liter heads-1 day-1. Improvements are needed in several aspects so the value of GDFP and GMiP could increase.

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.
