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: Penilaian Good Feeding dan Good Breeding Menggunakan Analytical Hierarchy Process pada Peternakan Sapi Perah Rakyat KPSBU Lembang
Abstrak: Sapi perah merupakan sapi yang dimanfaatkan untuk menghasilkan susu sebagai produk utama. Pengoptimalan produktivitas sapi perah dapat dilakukan dengan evaluasi Good Dairy Farming Practices (GDFP). Salah satu aspek GDFP adalah Good Feeding dan Good Breeding. Penelitian dilakukan dengan metode pengamatan secara langsung dan wawancara terhadap para peternak dan parah ahli. Analisis data dimulai dengan evaluasi Good Feeding dan Good Breeding, setelah itu pemeringkatan bobot prioritas untuk AHP, terakhir hasil evaluasi digabungkan dengan bobot AHP untuk mendapatkan nilai peforma gabungan. Hasil evaluasi Good Feeding dan Good Breeding secara berurutan adalah 3,52 (baik) dan 3,35 (cukup). Good Feeding merupakan faktor penentu paling penting dibandingkan dengan Good Breeding. Kriteria paling penting adalah kualitas konsentrat, sedangkan kriteria paling tidah penting adalah bangsa sapi yang dipelihara. Berdasarkan hasil penelitian ini perlu dilakukan lebih lanjut tentang pengembangan dengan kriteria prioritas tertinggi pada Good Feeding dan Good Breeding terhadap produktivitas sapi perah., Dairy cows are cows that are used to produce milk as the main product. Optimization of dairy cattle productivity can be done by evaluating Good Dairy Farming Practices (GDFP). This study aims to evaluate Good Feeding and Good Breeding and analyze the determinants that are most influential on the evaluation of Good Feeding and Good Breeding on dairy farms in KPSBU Lembang (case study: Manoko and Cisaroni). The research was conducted by direct observation method and interviews with breeders and severe experts. Data analysis begins with the evaluation of Good Feeding and Good Breeding, then the ranking of priority weights for AHP, finally the evaluation results are combined with AHP weights to obtain combined performance values. The evaluation results of Good Feeding and Good Breeding respectively are 3.52 (good) and 3,35 (sufficient). Good Feeding is the most important determining factor compared to Good Breeding. The most important criterion is the quality of concentration, while the last criterion is the nation of cattle raised. Based on the results of this study, it is necessary to do more about the vi development with the highest priority criteria on Good Feeding and Good Breeding on dairy cattle productivity.

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.
