Judul: Evaluation of Waste Management and Good Health (GDFP) Using Analytical Hierarchy Process of Dairy Farming (Case Study of Manoko and Cisaroni KPSBU Lembang)
Abstrak: Penelitian ini bertujuan mengevaluasi Good Dairy Farming Practice (GDFP) pada aspek kesehatan ternak (Good Health) serta lingkungan dan pengelolaan limbah (Waste Management) pada peternakan sapi perah rakyat KPSBU Lembang Wilayah Manoko dan Cisaroni. Penelitian menggunakan data analisis data dari Analytical Hierarchy Process (AHP) menggunakan analisis deskriptif yang diolah denga Expert Choice, jumlah responden yang digunakan sebanyak 10 peternak Wilayah Manoko dan 10 peternak Wilayah Cisaroni yang memiliki sapi perah sedang laktasi, dan 2 orang akademisi bidang sapi perah, 1 praktisi peternakan, serta 1 orang dinas bidang sapi perah. Hasil evaluasi GDFP aspek waste management dan good health mendapat nilai performa secara berurutan adalah 2,67 dan 2,94 (kurang baik). Kriteria yang paling diprioritaskan yaitu pencegahan penyakit (0,193) dengan capaian 50% sehingga capaian tersebut masih bisa ditingkatkan., This study aims to evaluate Good Dairy Farming Practice (GDFP) on aspects of Good Health and Waste Management in KPSBU Lembang Manoko and Cisaroni regions. Both aspects are not handled properly can make it easier for cows to contract diseases so that they can reduce cow productivity and harm farmers. The study used analysis data from the Analytical Hierarchy Process (AHP) using descriptive analysis processed with Expert Choice, the number of respondents use 10 farmers in the Manoko and 10 farmers in the Cisaroni who had lactating dairy cows, and 2 academics in the field of dairy cows, 1 livestock practitioner, and 1 person from the dairy cattle department. The results of the GDFP evaluation of good health and waste management aspects received performance scores of 3.44 and 3 (sufficient) respectively. The most prioritized criterion is disease prevention (0.193) with an achievement of 50% so that the achievement can still be improved.

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: 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.
