Judul: Analisis Pengaruh Infrastruktur dan Tenagakerja Terhadap Penanaman Modal Asing (PMA) di Kabupaten Karawang (Periode Tahun 1996-2013)
Abstrak: The Foreign Direct Investment is one means to achieve the success of economic development in a region . This study aims to analyze the influence of infrastructure and labor against FDI in Karawang district in 1996-2013. This study uses time series data years 1996-2013. OLS regression analysis were employed by using E-views 6. The results of this study indicate that the independent variables used in the study, i.e. the long road infrastructure (JLN) and electricity (LIST) have negative and significant relationship to the growth of foreign direct investment in Karawang district . Meanwhile, water infrastructure (AIR) and labor (TK) have positive and significant effects on the growth of foreign direct investment in Karawang district.

Judul: Analisis Pengaruh Investasi, Tenaga Kerja, dan Infrastruktur Terhadap Pertumbuhan Ekonomi Provinsi Jawa Barat
Abstrak: Economic growth is one indicator of development success in an area. This study is to analyze the effect of investment, work labour, and infrastructure to economic growth in West Java during the period 1990-2011. This study using time series data of 1990-2011 and it’s utilizes regression analysis of Ordinary Least Square (OLS) and supporting software from Eviews 6 and Minitab. The results of this study indicate that the independent variables FDI, domestic investment, and work labour has a positive and significant relationship to economic growth. It is also found that road length has a negative and significant relationship to economic growth, while government expenditure has not significant effect. Increased of local revenues by goverment should be done with create a conducive invesment climate so that the realization of infrastructure improvements can be accomplished, expanding employment opportunities, and boost government spending to improve the economy of West Java Province

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.
