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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
