Judul: Evaluasi Good Milking Practice Pada Peternakan Sapi Perah Rakyat di Kelurahan Kebon Pedes Kecamatan Tanah Sareal Bogor
Abstrak: Less hygienic handling of milk resulted in low quality and safety of milk causing major losses and reducing farmer income. Milking hygiene can be realized by implementing Good Milking Practice (GMiP). Interview and observation have been done to 29 sample farmers in Kebon Pedes, Tanah Sareal district, Bogor. The questionnaire was used as tool for observation and interview process. Three important aspects of Good Milking Practice have been evaluated i.e. (a) pre-milking (b) milking (c) post milking. The results showed that the highest value of Good Milking Practice had implemented by farmers aged 31-40 years. Farmers by 21-30 years experience result the highest Good Milking Practice value. Higher experience has no effect on the high value of GMiP. The result in implemented of Good Milking Practice showed that the farmers had less implemented of Good Milking Practice aspects in their dairy farm. This condition associated with low microbiological quality of the milk. The good enough farmers doing GMiP produce TPC but produce mastitis lower than poorly farmers doing GMiP. Amount of 876 quarters affected in cows, hind quarters showed higher involvement (55,81%) than fore quarters (44,19%).

Judul: Good Dairy Farming Practice dan Good Milking Practice Induk Sapi Perah Rakyat Peri-Urban Kecamatan Pangalengan
Abstrak: Good Dairy Farming Practice (GDFP) dan Good Milking Practice (GMiP) merupakan pedoman budidaya ternak perah yang berfungsi meningkatkan produksi dan kualitas susu. Penelitian ini bertujuan untuk mengetahui penerapan GDFP dan GMiP pada peternakan sapi perah rakyat kawasan peri-urban Kecamatan Pangalengan, Kabupaten Bandung, Jawa Barat. Peternak rakyat yang diamati pada penelitian ini adalah peternakan rakyat dengan sapi perah kurang dari 10 ekor. Pengambilan sampel menggunakan teknik multistage stratified random sampling, teknik ini diterapkan dengan memilih peternak secara acak pada tingkat koperasi dan kelompok peternak untuk mewakili kelompok tersebut. Pengumpulan data diperoleh dengan cara melakukan pengamatan langsung dan wawancara dengan peternak sapi perah yang dikunjungi. Penerapan GDFP pada peternakan rakyat daerah peri-urban dikategorikan baik dengan penerapan terbaik pada aspek kesehatan hewan. Penerapan GMiP pada peternakan rakyat daerah peri-urban dikategorikan cukup baik dengan penerapan terbaik pada aspek setelah pemerahan. Tingginya nilai GDFP dan beberapa aspek GMiP tidak terlepas dari peran KPBS Pangalengan dalam melakukan pelatihan, pendampingan, dan penyuluhan kepada peternak di daerah peri-urban secara berkala.

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.
