Judul: Good Housing and Good Management Using the Analytical Hierarchy Process in Jakarta People's Dairy Farms
Abstrak: Pondok Ranggon merupakan salah satu kawasan peternakan sapi perah yang berada di Jakarta. Aspek kandang peralatan dan pengelolaan merupakan faktor dalam good dairy farming practices (GDFP). Penelitian ini bertujuan mengevaluasi kriteria penentu yang paling prioritas pada Good Housing dan Good Management di peternakan sapi perah rakyat Pondok Ranggon Jakarta. Penelitian dilakukan dengan pengumpulan data primer yang diperoleh melalui wawancara kuisioner Good Housing dan Good Management berdasarkan panduan GDFP dan data sekunder diperoleh dari keterangan peternak dan studi pustaka. Data dianalisis menggunakan metode analisis deskriptif dan Analytical Hierarchy Process (AHP). Hasil GDFP pada Good Housing dan Good Management di peternakan sapi perah Pondok Ranggon tergolong baik dengan nilai performa 86,25% dan 85,31%. Nilai gabungan pengamatan dan vektor prioritas pada kedua aspek tersebut tergolong baik dengan nilai 85,31% pada aspek kandang dan peralatan dan 84,75% pada aspek pengelolaan. Prioritas utama pada aspek kandang dan peralatan adalah konstruksi kandang sedangkan pada aspek pengelolaan adalah pengeringan sapi laktasi., Pondok Ranggon is one of the dairy farming areas in Jakarta. Aspects of cage equipment and management are factors in good dairy farming practices (GDFP). This study aims to evaluate the criteria for determining the most priority on Good Housing and Good Management in the Pondok Ranggon people's dairy farm, Jakarta. The research was carried out by collecting primary data obtained through interviews with Good Housing and Good Management questionnaires based on GDFP guidelines and secondary data obtained from information from breeders and literature studies. Data were analyzed using descriptive analysis methods and Analytical Hierarchy Process (AHP). GDFP results on Good Housing and Good Management at the Pondok Ranggon dairy farm are classified as good with performance values of 86,25% and 85,31%. The combined value of observations and priority vectors for both aspects is classified as good with a score of 85,31% for the cage and equipment aspect and 84,75% for the management aspect. The main priority for the housing and equipment aspect is the construction of the stable, while the management aspect is drying the lactating cows.

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: 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.
