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: 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.
