Judul: Good Breeding and Good Feeding Determinants in Dairy Farms Pondok Rangon Jakarta
Abstrak: Pondok Ranggon adalah salah satu pusat peternakan sapi perah yang terletak di DKI Jakarta. Aspek reproduksi, dan pola pakan yang baik merupakan dua faktor dalam good dairy farming practices (GDFP). Penelitian ini bertujuan untuk mencari faktor penentu kedua aspek tersebut dalam pengelolaan peternakan melalui pengumpulan data primer yang diperoleh melalui wawancara kuisioner good breeding dan good feeding berdasarkan panduan GDFP serta data sekunder diperoleh dari keterangan peternak, dan studi pustaka. Data dianalisis menggunakan metode analisis deskriptif dan analitycal hierarchy process (AHP). Hasil evaluasi GDFP pada kedua aspek menunjukkan hasil tergolong baik dengan nilai performa 81,77% dan 85%. Nilai gabungan pengamatan dan vektor prioritas kedua aspek tergolong baik dengan capaian 81,40% dan 88%. Kriteria kualitas konsentrat pada aspek pakan dan air minum merupakan prioritas utama dengan nilai gabungan 13,175% dan bobot AHP 0,155. Pada aspek reproduksi, kriteria calving interval merupakan prioritas utama dengan nilai gabungan 22,61% dan bobot AHP sebesar 0,229. Solusi untuk perbaikan kondisi kedua aspek berdasarkan prioritas kriteria mencakup manajemen perkawinan, dan peningkatan kualitas konsentrat., Pondok Ranggon is one of the dairy farming centers located in DKI Jakarta. Reproductive aspects and good feeding patterns are two factors in Good Dairy Farming Practices (GDFP). This study aims to find the determinants for these two aspects in livestock management through primary data obtained via interviews questionnaires based on the GDFP guidelines and secondary data collected from farmers and literature studies. Data were analyzed using descriptive analysis methods and the Analitycal Hierarchy Process (AHP). GDFP evaluation on the aspects of reproduction and feeding at Pondok Ranggon dairy farm is classified as good with score of 81,77% and 85%. The combined value of observations and priority vectors for the two aspects is classified as good with score 81,40% and 88%. Concentrate quality criteria in the aspects of feed and water are top priority with a combined value of 13,175% and an AHP weight of 0,155. In the reproduction aspect, the calving interval criterion is a top priority with a combined value of 22,61% and an AHP weight of 0,229. Solutions for improving the condition of the two aspects include marital management, as well as increasing the quality of the concentrate.

Judul: Penilaian Good Feeding dan Good Breeding Menggunakan Analytical Hierarchy Process pada Peternakan Sapi Perah Rakyat KPSBU Lembang
Abstrak: Sapi perah merupakan sapi yang dimanfaatkan untuk menghasilkan susu sebagai produk utama. Pengoptimalan produktivitas sapi perah dapat dilakukan dengan evaluasi Good Dairy Farming Practices (GDFP). Salah satu aspek GDFP adalah Good Feeding dan Good Breeding. Penelitian dilakukan dengan metode pengamatan secara langsung dan wawancara terhadap para peternak dan parah ahli. Analisis data dimulai dengan evaluasi Good Feeding dan Good Breeding, setelah itu pemeringkatan bobot prioritas untuk AHP, terakhir hasil evaluasi digabungkan dengan bobot AHP untuk mendapatkan nilai peforma gabungan. Hasil evaluasi Good Feeding dan Good Breeding secara berurutan adalah 3,52 (baik) dan 3,35 (cukup). Good Feeding merupakan faktor penentu paling penting dibandingkan dengan Good Breeding. Kriteria paling penting adalah kualitas konsentrat, sedangkan kriteria paling tidah penting adalah bangsa sapi yang dipelihara. Berdasarkan hasil penelitian ini perlu dilakukan lebih lanjut tentang pengembangan dengan kriteria prioritas tertinggi pada Good Feeding dan Good Breeding terhadap produktivitas sapi perah., Dairy cows are cows that are used to produce milk as the main product. Optimization of dairy cattle productivity can be done by evaluating Good Dairy Farming Practices (GDFP). This study aims to evaluate Good Feeding and Good Breeding and analyze the determinants that are most influential on the evaluation of Good Feeding and Good Breeding on dairy farms in KPSBU Lembang (case study: Manoko and Cisaroni). The research was conducted by direct observation method and interviews with breeders and severe experts. Data analysis begins with the evaluation of Good Feeding and Good Breeding, then the ranking of priority weights for AHP, finally the evaluation results are combined with AHP weights to obtain combined performance values. The evaluation results of Good Feeding and Good Breeding respectively are 3.52 (good) and 3,35 (sufficient). Good Feeding is the most important determining factor compared to Good Breeding. The most important criterion is the quality of concentration, while the last criterion is the nation of cattle raised. Based on the results of this study, it is necessary to do more about the vi development with the highest priority criteria on Good Feeding and Good Breeding on dairy cattle productivity.

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.
