Judul: Penerapan Kesejahteraan Hewan Pada Peternakan Sapi Pedaging di Kecamatan Jonggol Kabupaten Bogor Jawa Barat
Abstrak: Peternakan sapi pedaging di Indonesia umumnya berskala kecil, dikelola secara tradisional, serta tidak diimbangi manajemen dan permodalan yang baik. Rendahnya pengetahuan dan pemahaman peternak mengakibatkan terabaikannya kesejahteraan hewan. Kesejahteraan hewan harus diperhatikan karena berpotensi meningkatkan produksi dan produktivitas sapi potong. Konsep lima kebebasan (five freedoms) digunakan sebagai acuan dalam mengevaluasi penerapan kesejahteraan hewan. Penelitian ini bertujuan menilai penerapan kesejahteraan hewan di peternakan sapi pedaging di Kecamatan Jonggol, Jawa Barat. Wawancara dan observasi menggunakan kuesioner dilakukan terhadap 32 peternakan rakyat. Data dianalisis menggunakan analisis deskriptif kuantitatif. Hasil penelitian menunjukkan upaya penerapan kesejahteraan hewan dikategorikan kurang dengan penerapan sebesar 51,56%. Aspek bebas, lapar, dan haus menjadi aspek yang terendah penerapannya (44,53%) sehingga diperlukan perhatian lebih. Aspek dengan penerapan dalam kategori cukup, dapat ditingkatkan melalui peningkatan pengetahuan dan kesadaran peternak untuk meningkatkan produktivitas ternak., Beef cattle farming in Indonesia is generally small-scale, managed traditionally, and lacks proper management and financing. The low knowledge and understanding of farmers have resulted in the neglect of animal welfare. Animal welfare must be considered as it has the potential to enhance beef cattle production and productivity. The concept of the five freedoms is used as a reference to evaluate the implementation of animal welfare. This research aims to assess the application of animal welfare in beef cattle farming in Jonggol District, West Java. Interviews and observations using a questionnaire were conducted with 32 small-scale farms. The data were analyzed using quantitative descriptive analysis. The results of the research indicate that the efforts to implement animal welfare are categorized as inadequate, with an implementation rate of 51,56%. The aspects of freedom from hunger and thirst were found to have the lowest implementation rate (44,53%), requiring more attention. Aspects categorized as sufficient can be improved through increasing farmers' knowledge and awareness to enhance livestock productivity.

Judul: Evaluasi Penerapan Good Farming Practice pada Peternakan  Rakyat Sapi Potong di Situ Bolang Indramayu
Abstrak: Produktivitas ternak sapi potong domestik belum cukup untuk memenuhi kebutuhan dalam negeri. Sebanyak 90% peternakan sapi di Indonesia dikelola secara tradisional. Penelitian bertujuan mengevaluasi pengelolaan peternakan sapi potong di Peternakan Situ Bolang sesuai Peraturan Menteri Pertanian Republik Indonesia Nomor 46/Permentan/PK.210/8/2015 tentang Good Farming Practice untuk Sapi Potong. Penelitian menggunakan analisis deskriptif kualitatif wawancara kepada 33 responden menggunakan kuesioner dan pengamatan secara langsung. Hasil penelitian dapat dilihat dari nilai aspek Good Farming Practice yaitu pembibitan dan reproduksi, manajemen pakan, tata laksana pemeliharaan, perkandangan, dan kesejahteraan ternak. Penerapan GFP oleh peternak rakyat di Situbolang Indramayu mendapatkan nilai 2,05 tergolong dalam kategori sangat kurang., Domestic beef cattle productivity is not sufficient to meet domestic demand. As many as 90% of cattle farms in Indonesia are managed traditionally. The study aimed to evaluate the management of beef cattle farming in Situ Bolang Farm according to the Regulation of the Minister of Agriculture of the Republic of Indonesia Number 46/Permentan/PK.210/8/2015 about Good Farming Practice for Beef Cattle. The study used descriptive qualitative analysis of interviews with 33 respondents using questionnaires and direct observation. The results of the study can be seen from the value of aspects of breeding and reproduction, feed management, rearing procedures, cowshed, and animal welfare. Implementation of GFP by smallholder farmers in Situbolang Indramayu received a score of 2.05, which is classified as very lacking.

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.
