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 Good Health Using Analytical Hierarchy Process at Mandiri Sejahtera Cijeruk Dairy Farming Group
Abstrak: Salah satu upaya yang dapat dilakukan untuk meningkatkan produksi dan kualitas susu yaitu melalui implementasi Good Dairy Farming Practices (GDFP). Penelitian ini bertujuan menganalisis dan mengevaluasi faktor penentu yang paling berpengaruh terhadap aspek good health pada Kelompok Ternak Mandiri Sejahtera (KTMS) di Desa Tajur Halang menggunakan Analytical Hierarchy Process (AHP). Metode yang digunakan yaitu pengamatan dan wawancara secara langsung kepada 24 orang peternak yang tergabung dalam KTMS, menggunakan kuesioner yang mengacu kepada Komala et al. (2022) dan 3 responden ahli yang terdiri dari akademisi, praktisi, dan instansi pemerintahan. Hasil yang diperoleh menunjukkan bahwa nilai tertinggi berdasarkan gabungan nilai pengamatan dan vektor prioritas dari para ahli sebesar 37,34% pada kriteria pencegahan penyakit dengan nilai AHP sebesar 0,39 dan nilai terendah pada kriteria penanganan pasca sakit berdasarkan gabungan nilai pengamatan dan vektor prioritas dari kesehatan ternak sebesar 14,66% dengan nilai AHP sebesar 0,17. Kriteria ini harus menjadi aspek yang diprioritaskan oleh para peternak untuk memperoleh hasil yang optimal., Efforts that can be made to increase milk production and milk quality can be achieved through the implementation of Good Dairy Farming Practices (GDFP). This study aim is to analyze dan evaluate the most influential determining criteria in good health aspect using Analytical Hierarchy Process (AHP). The method used is a survey method with direct interviews to 24 dairy farmers in Mandiri Sejahtera Farms, using a questionnaire that refers to Komala et al. 2022 and 3 experts consists of academics, practitioners, and government. The results showed that the highest determining criteria based on combined observation value and priority vector of good health was 37,34% of disease prevention with an AHP score 0,39 and the lowest was in post-illness management based on combined observation value and priority vector of good health was 14,66% with an AHP score 0,17. The criteria is a priority aspect that must be prioritized to be maximized.

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.
