Judul: Evaluation of Good Health and Good Milking Practices Using Analytical Hierarchy Process (AHP) of Dairy Farms in Jakarta
Abstrak: Salah satu upaya untuk meningkatkan sifat kualitatif dan kuantitatif produksisapi perah adalah dengan mengevaluasi penerapan aspek kesehatan (Good Health) dan mengevaluasi penerapan Good Milking Practices (GMiP). Oleh karena itu, penelitian ini bertujuan untuk mengevaluasi faktor penentu yang paling berpengaruh dalam evaluasi pada aspek kesehatan dan GMiP (aspek ketika, sebelum, dan setelah). Penelitian ini dilakukan pada bulan Maret 2023 hingga Mei 2023. Aspek kesehatan dan GMiP dievaluasi dengan menggunakan Analytical Hierarchy Process menggunakan software Expert Choice dengan mengombinasikan pendapat dari tiga responden ahli yang berasal dari akademisi, praktisi, dan dinas terkait untuk melihat faktor penentu yang paling berpengaruh. Wawancara juga dilakukan kepada 20 orang peternak rakyat untuk menilai lansgung kondisi Peternakan. Hasil evaluasi Good Health sebesar 30,1 % dan hasil evaluasi GMiP aspek ketika, sebelum, dan sesudah pemerahan secara berturut-turut sebesar 20,96%; 11,48%; 10,30%. Nilai performa gabungan pengamatan dan vektor prioritas yang diperoleh sebesar 72,84% yang termasuk dalam kategori cukup., One effort to improve the qualitative and quantitative characteristics of dairy cattle production is to evaluate the application of the health aspect (Good Health) and the application of Good Milking Practices (GMiP). Therefore, this study aims to evaluate the most influential determinants in evaluating aspects of Health and GMIP (aspects when, before, and after). This research was conducted from March 2023 to May 2023. The health and GMiP aspects were evaluated using the Analytical Hierarchy Process using the Expert Choice software by combining the opinions of three expert respondents from academics, practitioners, and related agencies to see the most influential determinants. Interviews were also conducted with 20 community breeders to assess the condition of the farms directly. The results of the Good Health evaluation were 30.1%, and the results of the GMiP evaluation during, before, and after milking were respectively 20.96%, 11.48%, and 10.30%. The combined performance value of observations and priority vectors obtained is 72.84% which is included in the sufficient category.

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: 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.
