Abstrak: Rice is the primary food for 95 percent of Indonesia's population and consumption levels 139 kilograms by capita by year. The purpose of this study was to analyze the system of rice marketing that includes channel marketing, marketing institutes, marketing functions, market structure and market behavior. In addition, this research analyzes the efficiency of rice marketing in any type of marketing channels. Results from this research that rice marketing channels in Banyuwangi regency consists of 12 channels and there are six types of institutions marketing (farmers group, middleman, milling, wholesalers, retailers and sub regional division Bulog). Total harvest rice planting season I 2012 as much as 272.880 kilograms GKP or equivalent 150.084 kilograms of rice. Marketing efficiency analysis proves that the channel VII distribute 31.755,50 kilograms of rice. Highest marketing costs 1,512 rupiah per kilogram on channel XII. Greatest value of margin marketing is also on the channel XII is equal to 2.721 rupiah per kilogram. Channel III has a value of the farmer's share of 79 percent. Farmer's share value higher on a channel other than the channel marketing shows the channel operationally efficient

Judul: Analisis Sistem Pemasaran Beras Ciherang di Kecamatan Cibeber, Kabupaten Cianjur
Abstrak: Rice is the basic commodity that became the staple food for the Indonesian. The purposes of this research were analyzing marketing channels, function, structure and marketing institutions of farmer Ciherang Variety in Cibeber Subdistrict. Beside that, the purposes of this research were analyzing the marketing efficiency by marketing margin, farmer’s share and benefit cost ratio approaching. The research was conducted in 3 villages that are Cisalak, Karangnunggal, Salamnunggal with 30 farmers as the respondents and there are 7 marketing institutions in the subdistrict. Generally, the market structure in this subdistrict is oligopsonistic . Based on the marketing function and the profitable ratio about marketing cost, the channels that through farmers-middlemen-major collector and rice mills in village-retailer-consumer rice in Jakarta is the most efficient channels. The farmer should have made farmer groups or cooperation as part of the marketing system to improve the bargaining position and easier capitalization like through the warehouse system in Cianjur.

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.
