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 Management dan Milking Practices Menggunakan Analytical  Hierarchy Process pada Peternakan Sapi Perah Rakyat KPSBU Lembang
Abstrak: Sapi perah mempunyai kontribusi besar terhadap penentu kebutuhan susu setiap tahun yang terus meningkat. Penerapan Good Dairy Farming Practice (GDFP) dan Good Milking Practice (GMiP) berperan penting terhadap kualitas dan keamanan susu. Penelitian bertujuan mengetahui faktor penentu yang paling berpengaruh pada evaluasi GDFP pada aspek Good Management dan GMiP di peternakan sapi perah rakyat KPSBU Lembang dengan menggunakan analisis data Analytical Hierarchy Process (AHP). Metode yang digunakan yaitu metode survei dan wawancara langsung kepada 10 peternak di Manoko dan 10 peternak di Cisaroni yang merupakan anggota Koperasi Peternak Sapi Perah Bandung Utara (KPSBU) serta 4 orang ahli yang terdiri dari akademisi, praktisi, dan pemerintah. Hasil evaluasi Good Milking Practice (GMiP) pada aspek ketika pemerahan, aspek sebelum pemerahan, dan aspek setelah pemerahan berturut-turut memiliki nilai 3,85; 3,84; 3,79 serta hasil evaluasi GDFP aspek good management memiliki nilai 3,65. Kriteria yang paling diprioritaskan adalah pengeringan sapi laktasi dan yang paling tidak diprioritaskan adalah kriteria peralatan dan lantai. Kata kunci: GDFP, GMiP, sapi perah, Dairy cows have a major contribution to determining the demand for milk every year which continues to increase. The implementation of Good Dairy Farming Practice (GDFP) and Good Milking Practice (GMiP) plays an important role in the quality and safety of milk. The aim of this study was to determine the determinants that most influenced the evaluation of GDFP on the Good Management and GMiP aspects of the KPSBU Lembang small dairy farm by using the Analytical Hierarchy Process (AHP) data analysis. The methods used are survey methods and direct interviews with 10 farmers in Manoko and 10 farmers in Cisaroni who are members of the North Bandung Dairy Farmers Cooperative (KPSBU) and 4 experts consisting of academics, practitioners and the government. The evaluation results for Good Milking Practice (GMiP) aspects during milking, aspects before milking, and aspects after milking respectively have a value of 3,85; 3,84; 3,79 and the results of the evaluation of the GDFP aspect of good management have a value of 3,65. The most prioritized criteria is the drying of lactating cows and the least prioritized are equipment and floor criteria. Keywords: dairy cows, GDFP, GMiP

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.
