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 Tata Kelola Pemerintahan Daerah Terhadap Realisasi Investasi di Provinsi Jawa Timur
Abstrak: Regional governance is one of important supporting factors in stimulating investment realization in every region. The aims of the study are (1) to describe the perceptual difference among businessmakers in East Java based on regional governance survey held by KPPOD (Komite Pemantauan Pelaksanaan Otonomi Daerah) in 2007 and 2010, (2) to analyze the linkages between regional governance and investment realization in East Java, and also (3) to analyze the impact of regional governance to investment realization in East Java. Data used in this research consist of 2 period, 2005-2007 and 2008-2010, and 38 districts and municipals in East Java. Data are taken from Investment Coordinating Board, Central Bureau of Statistics Indonesia and Directorate General of Fiscal Balance (DJPK). Methods used are descriptive statistic ,using Pearson and Spearman correlation, and also static panel data regression. Perceptual difference on the latter survey, as the first result, found to be significantly better and even worse than the previous one for some major variables . Results also showed that there is a strong linkage between foreign direct investment, domestic private investment, public investment and regional governance. The elements of regional governance that affected domestic investment are percentages of businessmaker having business licence (Tanda Daftar Perusahaan) and also dummy of regional government program in promoting local potential product/commodity. The elements of regional governance that affected foreign direct investment are dummy of donation barrier to the regional government, dummy of the regent/municipal’s comprehension to the business matters and dummy of the quality of road infrastructure.

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.
