Judul: Pengaruh Tata Kelola Ekonomi Daerah Terhadap Tingkat Pengangguran Kabupaten/Kota di Provinsi Jawa Timur
Abstrak: Regional autonomy policy since 2001 aims to growing national development and evenly the lower unemployment rate. One way to reduce unemployment rate is increasing private investment in improvement of Local Economic Governance (LEG). East Java has a large number of population and unemployment rate reached 4% in 2013. There are still inequalities across districts and cities. The purpose of this study is to describe and analyze the condition and development of LEG, analyzing the effect on the unemployment rate LEG districts and cities of East Java Province. Variables used in this study are nine sub index LEG, capital expenditures and investments. The result shows that some districts and cities in East Java as the top ten highest LEG score national rank. Three sub index increased, one decreased and six did not change from 2007 to 2011. With multiple regression analysis resulted in sub index of private enterprise development programs do not affect the unemployment rate, while capital expenditures, investments, and eight sub index LEG affect the unemployment rate

Judul: Pengaruh Tata Kelola Ekonomi Daerah Terhadap Tingkat Kemiskinan dan Indeks Pembangunan Manusia di Kawasan Timur Indonesia
Abstrak: East Indonesia is a part of Indonesian region which has a wealth of natural that can be developed and potential to become a growth centers. However, this wealth natural resource has not been supported by human resource both in quality and quantity. This can be reflected from the HDI (Human Development Index) in a relatively low in East Indonesia. Regional autonomy was implemented in Indonesia since 2001 aims to improve the welfare of the society and is expected to increase HDI and reduce poverty. The objective of this study is to describe Local Economic Governance (LEG), poverty and HDI in the region and to analyze the impact of LEG on poverty and HDI in East Indonesia. The data were processed using descriptive analysis and multiple regression analysis to estimate Ordinary Least Square. The results showed that LEG conditions in East Indonesia still inequity. The level of poverty districts/cities in East Indonesia is still high and HDI is still relatively low. Variables that can significantly increase the HDI in East Indonesia is business licensing, regulatory regions, capacity and integrity of regent / mayor, security and conflict resolution, as well as GDP per capita and education spending. While the variables that can reduce the level of poverty is local infrastructure, business licensing, capacity and integrity of regent/mayor, security and conflict resolution, GDP per capita and education spending .

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.
