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: Dampak Investasi, Belanja Pemerintah dan Angkatan Kerja terhadap Kinerja Ekonomi di Kota Bogor
Abstrak: The role of local governments in Indonesia can be considered very dominant since the era of regional autonomy in 2001. As the implications of granting authority ' s broader to local governments, the required to independently executing development, both the planning or implementation is based on the principles of regional autonomy. Economic growth cannot be separated from the role of government spending in the public services. Local government spending is measured from the total routine expenditure and development spending allocated in the budget area. Meanwhile, local government expenditures depends on regional income which includes the transfer and revenue. This study was aimed at describing between General allocation fund and Regionally Original Income which one has more influence on the regions’ spending, and analyze the magnitude of the impact of investment, local government expenditures and labor force against economic performance in Bogor city. The method used is descriptive analysis and multiple linear regression and is suspected by the method of Ordinary Least Square (OLS). To analyze the economic performance used secondary data from 1990 through 2011. To analyze the independence of local governments used secondary data from 2001 through 2011. Identification results showed that the transfer ratio (General and Special allocation fund) to total local revenues showed a negative slope, and the ratio of local revenue (Local Revenue and Revenue-sharing) of the total revenues showed a positive slope so it can be said to be Independently in revenues for Bogor city, although still dependent to the central government. The results also show that General allocation fund and Regionally Original Income significant effect on total expenditures, and the response of total regional expenditures to greater Regionally Original Income rather than transfer of funds (General allocation fund), so it can be said that the present Bogor City more self-reliant in the reception. Research also shows that economic growth is positively and significantly influenced by investment the previous year (INVt-1), infrastructure spending, education spending three years earlier, and the total labor force. City minimum wage significant negative effect on investment (INV) in Bogor City. But the city minimum wage, health expenditures and investment the previous year (INVt-1) positive significant effect on the human development index.

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.
