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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
