Judul: Penggudangan Beras Komersial dalam Mengantisipasi Penerapan "Warehouse Receipts System"
Abstrak: Penerapan Warehouse Receipts System (WRS) membutuhkan berbagai prasarana dan sarana pendukung demi kelancaran sistem ini. Penggudangan merupakan salah satu sarana yang sangat penting bagi pelaksanaan WRS, sehingga perlu dilakukan suatu analisis tentang kelayakan pendirian suatu gudang beras baik yang akan disewakan maupun untuk pengelolaan gudang beras.

Judul: Pengaruh Sistem Resi Gudang Terhadap Pendapatan Usahatani Padi di Kecamatan Perak Kabupaten Jombang
Abstrak: Warehouse Receipt System is a system relates to issuance, transfer, loaning, and warehouse receipt transaction settlement. WRS contained in the Law Number 9 of 2006 expanding public accesss to capitalize upon financing facility. The purposes of the research are to analyze the implementation of WRS, to identify the affecting factors in implementing WRS, and to analyze the role of WRS in increasing the farmers’ income. The research was conducted in Plosogenuk Village Perak Subdistrict Jombang District, East Java by respondents of 40 farmers. The research was conducted by comparing the ongoing study that showed the implementation of WRS in Perak Subdistrict in general was conformed with the average rate by 69% of conformity. Some less-conformed components were the lack of socialization and the less-appropriate specification of warehouse. However, the implementation of WRS helped farmers in income increase by 22.46% which derived from the increase of the selling price by 6.46%.

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.
