Judul: Analisis Preferensi Pangan Masyarakat Dan Daya Dukung Gizi Menuju Pencapaian Diversifikasi Pangan Kabupaten Bogor
Abstrak: General objective of this study is to analyse Community’s Food Preference and nutritional carrying capacity in the direction of food diversification achievement in Bogor Regency. The spesific objectives are (1) to analyse individual characteristic sample i.e. last education, salary per capita, expenditure per capita, (2) to identify environment characteristic i.e. number of family, job, information from mass media, and production, (3) to identify food preference, (4) to analyse the correlation between food preference with individual and environment characteristic, (5) to analyse local food’s production and preference. Design of this study was cross sectional study with cluster analysis and simple random sampling. Number of sample is 106 for two region characteristics. Data were analized by Microsoft Excel and SPSS 16.0 for Window. Food preference of Bogor Regency community shows that almost sample like to 9 food groups in Desireable Dietary Pattern. The reason of this food preference is food factor (taste, nutrition content, food processing). Local food potential in order to reach food diversification consider to food preference and production. It also an alternative way to fulfill carbohidrat, animal and plant based protein, vitamin and mineral needs. Output of Chi square dan Spearman analysis show that almost food don’t have correlation (p>0.05) with individual and environmental characteristic. Potensial local food based on food preference and production as alternative food for food diversification i.e. corn, cassava, sweet potato, taro (carbohydrate sources): fish, mung bean, tempe, tofu (protein sources); and green leaf vegetables, cow peas, banana and guava (vitamins and minerals sources). Production data shows that corn, fish, mung bean, and soybean production need to be increased its production or import from the other region, especially in West Java. This analysis need to support food preference and by itself it will also support food diversification.

Judul: Analysis of the Development of Superior Food Crop Commodities at Subdistrict Level in Bogor Regency
Abstrak: Kabupaten Bogor memiliki potensi dalam pengembangan subsektor tanaman pangan yang berperan besar terhadap perekonomian dan ketahanan pangan daerah. Penurunan luas lahan pertanian menjadi masalah yang dihadapi dalam pengembangan subsektor tersebut sehingga dibutuhkan upaya untuk mengoptimalkan pemanfaatan lahan melalui pengembangan komoditas unggulan. Penelitian ini bertujuan untuk (1) Mengidentifikasi komoditas unggulan tanaman pangan pada tingkat kecamatan di Kabupaten Bogor; (2) Menganalisis tingkat spesialisasi dan lokalisasi dari komoditas unggulan tanaman pangan; (3) Menganalisis prioritas pengembangan komoditas unggulan tanaman pangan pada tingkat kecamatan; dan (4) Menganalisis upaya pengembangan komoditas unggulan tanaman pangan oleh Pemerintah Daerah Kabupaten Bogor. Metode yang digunakan dalam penelitian antara lain metode analisis deskriptif, location quotient (LQ), kuosien spesialisasi, dan kuosien lokalisasi. Hasil penelitian menunjukkan bahwa komoditas tanaman pangan dengan wilayah basis terbanyak di Kabupaten Bogor adalah padi sawah, kacang tanah, ubi kayu, ubi jalar, dan talas. Tidak ada spesialisasi dan pemusatan komoditas unggulan tanaman pangan pada tingkat kecamatan. Semua komoditas tanaman pangan menjadi komoditas yang diprioritaskan untuk dikembangkan pada tingkat kecamatan. Pemerintah Daerah Kabupaten Bogor dan dinas terkait telah melaksanakan Program Peningkatan Produksi, Produktivitas, dan Nilai Tambah Tanaman Pangan yang terdiri dari kegiatan pengelolaan produksi hingga pengolahan dan pemasaran produk hasil pertanian tanaman pangan., Bogor Regency has potential in the development of the food crop subsector, which has a major role in the regional economy and food security. The decrease in the area of agricultural land is a problem faced in the development of this subsector, so efforts are needed to optimize land use through the development of superior commodities. This study aims to (1) identify the superior commodities of food crops at the subdistrict level in Bogor Regency; (2) analyze the level of specialization and localization of superior food crop commodities; (3) analyze the priority of developing superior food crop commodities at the subdistrict level; and (4) analyze efforts to develop superior food crop commodities by the Regional Government of Bogor Regency. The methods used in this study include descriptive analysis methods, location quotient (LQ), specialization quotient, and localization quotient. The results showed that the food crop commodities with the largest base area in Bogor Regency are lowland rice, peanuts, sweet potatoes, cassava, and taro. There is no specialization and centralization of superior food crop commodities at the subdistrict level. All food crop commodities are prioritized to be developed at the subdistrict level. The Regional Government of Bogor Regency and related agencies have implemented the Program to Increase Production, Productivity, and Added Value of Food Crops, which consists of activities from production management to processing and marketing of food crop agricultural products.

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.
