Judul: Analisis Tataniaga Beras di Kecamatan Rogojampi Kabupaten Banyuwangi
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 Rantai Pemasaran Beras IR-42 (Distribusi dari Kabupaten Subang Ke DKI Jakarta)
Abstrak: Subang in Pasar Induk Beras Cipinang, DKI Jakarta, is known as the supplier of IR-42 rice. IR-42 is one of premium rice ini Indonesia that the price of this rice is higher than the other. However, benefits of the high price of this rice is not earned equally by all actors in the marketing chain. In the other hand, the benefit of the high price of the rice is not The objective of this study is to analiyze the caharacteristics of the IR-42 rice marketing chain from Subang Region to DKI Jakarta, and also to analyze the marketing efficiency rate of the rice marketing chain from Subang to Pasar Induk Beras Cipinang. The characteristics of this marketing channel is analyzed by the supply chain frame work developed by Vorst (2006). While, the analysis of the marketing efficiency is used because it is not possible to measure its performance by the supply chain performance, because there is no supply chain network in this marketing chain.The result of this study indicates that the integrated channel is more efficient than any channel. Developing this marketing channel is important, especially related to its coordination and collaboration among all the actor in this marketing channel

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
