Judul: An Analysis of Role of Capital Expenditure as Government Investment on Economic in East Indonesia Year 2005-2009
Abstrak: How important was government investment in enhancing The East Indonesia’s economy? Using a dataset of regional government spending and panel data (First-difference Generalized Method of Moments), it show that regional government in East Indonesia still depend on central government for their government revenue and policy. Fiscal independence from regional government in East Indonesia were low and declining every year. The research also find that government investment especially on infrastructure (irrigation, street, and telecommunication/network) have positive impact for economic growth in East Indonesia. And also have complementer relation with private investment, which mean both investment have contribution on accumulation investment for higher output and aggressive economic growth. These results suggest that regional government must explore their potential resources to increase their own-source revenue (pendapatan asli daerah, or PAD) so they can have higher fiscal independence. Regional government can create favorable environtment to attract private investor so later on it will provide jobs and become source of government revenue.

Judul: Pengaruh tata kelola ekonomi dan belanja modal daerah terhadap realisasi investasi di Indonesia
Abstrak: Investment is a driver of economic development in Indonesi. Realized investment may be affected by two factors, namely economic governance and capital expenditure areas. The purpose of this study was to analyze the relationship between the realized investment with economic governance and capital expenditures. This study uses cross section data in 2011 with the OLS method and analysis unit 142 counties or cities in Indonesia. The independent variables used in this study was a score of Local Economic Governance consisting of local infrastructure, Private Sector Development Programme, local government interaction with business, land access, and business licensing, and other independent variables, namely capital expenditures area. The results of the analysis show that four independen variables has a positive relationship to realized investment in Indonesia. Meanwhil, Private Sector Development Programme were negatively related to realized investment in Indonesia and access to land does not have a significant relationship to the realized investment

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.
