Judul: Good Animal Welfare, Environment, dan Waste Management Practices Peternakan Sapi Perah Menggunakan Analitical Hierarchy Process
Abstrak: Peternakan sapi perah menjadi salah satu pilar yang turut andil dalam menopang kebutuhan manusia akan terpenuhinya protein hewani. Produk utama dari sapi perah yaitu susu. Faktor kesejahteraan dan manajamen lingkungan dapat mempengaruhi produktivitas susu dan reproduksi sapi perah. Penelitian ini bertujuan menganalisis ketercapaian good animal welfare, environment, dan waste management practices di peternakan sapi perah Pondok Ranggon. Penelitian ini menganalisis ketercapaian good animal welfare, environment, dan waste management practices di peternakan sapi perah Pondok Ranggon dengan data primer dan sekunder. Data primer berupa data GDFP. Data sekunder diperoleh dari laporan peternak, studi literatur, informasi dari instansi terkait, dan hasil penelitian yang relevan. Peternakan yang diteliti berjumlah 25 orang peternak dengan jumlah sapi perah 174 ekor menggunakan analisis AHP yang dilaksanakan dari bulan Oktober sampai November 2022. Hasil penelitian menunjukan bahwa manajamen lingkungan dan penerapan animal walefare berpengaruh penting terhadap kenyamanan serta produktivitas ternak.

Judul: Animal Welfare dan Good Housing Menggunakan Analytical Hierarchy Process pada Peternakan Sapi Perah Rakyat KPSBU Lembang.
Abstrak: Peningkatan produksi susu sapi perah dapat diupayakan dengan Good Dairy Farming Practices (GDFP). Salah satu aspek penentu GDFP adalah Animal Welfare dan Good Housing. Penerapan Animal Welfare dan Good Housing yang baik dapat meningkatkan produktivitas sapi perah. Penelitian ini bertujuan mengevaluasi dan menganalisis kriteria penentu yang paling berpengaruh dalam GDFP aspek Animal Welfare dan Good Housing dengan menggunakan 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 penelitian menunjukkan aspek Animal Welfare lebih penting daripada Good Housing. Kriteria penentu tertinggi berdasarkan nilai gabungan pengamatan dan vektor prioritas dari Animal Welfare adalah bebas dari lapar dan haus sebesar 18,98% dengan bobot AHP 0,276, sedangkan dari Good Housing adalah peralatan susu 14,15% dengan bobot AHP 0,149., Increasing the milk production of dairy cows can be attempted with Good Dairy Farming Practices (GDFP). One of the defining aspects of GDFP is Animal Welfare and Good Housing. Good application of Animal Welfare and Good Housing can increase the productivity of dairy cows. This study aims to evaluate and analyze the most influential determining criteria in GDFP aspects of Animal Welfare and Good Housing by using the Analytical Hierarchy Process (AHP). The method used is a survey method and 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, practitioner, and the government. The results of the research show that the Animal Welfare aspect is more important than Good Housing. The highest determining criterion based on the combined observation value and priority vectors from Animal Welfare is free from hunger and thirst 18,98% with an AHP weight of 0,276, while from Good Housing is milk equipment 14,15% with an AHP weight of 0,149.

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.
