Judul: Pengaruh Upah Minimum terhadap Perekonomian di Provinsi Jawa Barat
Abstrak: Upah merupakan salah satu instrumen yang memiliki dua makna berbeda bagi perusahaan dan pekerja sehingga menimbulkan permasalahan yang cukup kompleks dan memerlukan campur tangan pemerintah, salah satunya melalui upah minimum. Penelitian ini bertujuan menganalisis pengaruh upah minimum terhadap perekonomian di Provinsi Jawa Barat, dengan menggunakan model persamaan simultan serta data pooled time series–cross section 26 kabupaten/kota di Provinsi Jawa Barat pada tahun 2009-2013. Hasil analisis menunjukkan bahwa dugaan parameter model sesuai dengan teori. Pada penelitian ini dilakukan dua simulasi, yaitu dengan menaikkan UMK sebesar 10% pada simulasi pertama dan simulasi kedua dilakukan dengan menaikkan UMK dan pengeluaran pemerintah sebesar 10%. Berdasarkan hasil simulasi pertama, kenaikan UMK akan meningkatkan konsumsi, investasi dan PDRB namun menurunkan penyerapan tenaga kerja. Sementara hasil simulasi kedua yaitu meningkatkan konsumsi, investasi dan PDRB serta mengurangi angka penurunan penyerapan tenaga kerja.

Judul: The Impact of Provincial Minimum Wage Policy on Poverty in Java Island (2010-2018 Period)
Abstrak: Tingkat kemiskinan di Pulau Jawa masih saja tinggi dan belum merepresentasikan kesejahteraan di seluruh provinsi. Tetapi keadaan kemiskinan yang terjadi terus menunjukan tingkat penurunan. Penerapan kebijakan upah minimum merupakan salah satu jalan yang diambil pemerintah dalam menekan kemiskinan melalui bidang ketenaga kerjaan. Namun, efektivitas penerapan kebijakan upah minimum provinsi sebagai suatu kebijakan yang dirancang untuk melindungi kondisi ekonomi masih diperdebatkan. Penelitian ini bermaksud untuk mengetahui dampak dari penerapan kebijakan Upah Minimum Provinsi terhadap tingkat kemiskinan di Pulau Jawa periode tahun 2010-2018. Data yang digunakan adalah data enam Provinsi di Pulau Jawa. Metode yang digunakan dalam penelitian ini adalah analisis regresi data panel dan Fixed Effect Model (FEM). Hasil analisis regresi menunjukan bahwa varibel Upah Minimum Provinsi (UMP) berdampak signifikan pada kemiskinan sedangkan variabel Produk Domestik Regional Bruto (PDRB) berpengaruh signifikan negatif terhadap tingkat kemiskinan di Pulau Jawa selama periode penelitian., The poverty rate in Java is still high and does not represent welfare in all provinces. However, the state of poverty that occurs continues to show a decreasing rate. The implementation of the minimum wage policy is one of the ways the government takes to reduce poverty through the labor sector. However, the effectiveness of implementing the provincial minimum wage policy as a policy designed to protect economic conditions is still being debated. This study intends to determine the impact of the implementation of the Provincial Minimum Wage policy on poverty levels in Java for the period 2010-2018. The data used is data from six provinces in Java Island. The method used in this research is panel data regression analysis and Fixed Effect Model (FEM). The results of the regression analysis show that the Provincial Minimum Wage (UMP) variable has a significant impact on poverty while the Gross Regional Domestic Product (GRDP) variable has a significant negative effect on the poverty level in Java during the study period.

Judul: Application of phycocyanin from microalgae Spirulina platensis as light harvesting in anatase TiO2 nanoparticle solar cell.
Abstrak: The dye sensitized solar cell (DSSC) has been assemblied used hybrid titanium oxide (TiO2) film/phycocyanin. The TiO2 film was synthesized by sol gel method with titanium chlorida (TiCl4) as precursor by hydrolysis used sulfuric acid (H2SO4). Furthermore, it calcinated for 2,5 hours in variation of annealing temperature (400oC, 600oC, 800oC, dan 1000oC). In XRD patterns exhibited which annealing temperature at 400oC to 800oC were anatase phase all. When annealed at temperature 1000oC, it caused phase transformation from anatase to rutile. The crystals size according to XRD patterns were 13,75 nm, 20,79 nm, 25,25 nm, 48,88 nm and particle size from SEM images were 43,06 nm, 44,91 nm dan 64,99 nm, 80,40 nm, respectively. The crystals and particle size increased with annealing temperature. The film thickness influenced material absorption. The optical measurement of TiO2 film and TiO2/phycocyanin hybrid film used UV-Vis spectrophotometer. Additional phycocyanin caused peak width of absorbed region from ultraviolet to visible region. The band gap energy of TiO2 can be calculated using the cut off wavelength obtained from the absorbance spectrum of a nanoparticles TiO2 films. Based on intersection between linear and energy (hv) axis. In this study just limited for anatase phase. It was caused anatase band gap is wider than rutile phase. That’s meaningful for solar cell application such as dye sensitized solar cell (DSSC). The absorption coefficient average at difference annealing temperature such as at 400oC, 600oC, 800oC were 8,1600x102, 1,7535x103 and 4,0154x102, where α < 104 include to direct transition. Band gap energy 400oC, 600oC, 800oC were 3,79 eV, 3,59 eV, and 3,35 eV, respectively. Based on this result, exhibition that band gap energy of TiO2 semiconductor film decreased with increasing annealing temperature. Spirulina platensis was cultivated in technical modification (Hastuti) with aeration under light intensity about 3000 lux. The cell density (stationer phase) for eighth day which OD value was more than 0,5. It means, the culture can be harvested. In 80 liters Spirulina platensis culture have been produced biomass dry about 10,46 gram and extracted phycocyanin in dry powders was 5,50 gram. The phycocyanin absorption spectrum at the wavelength of 619,36 nm (visible region) which had relaxation energy was 2,945 eV. The emission peak at the wavelength of 708,55 nm with relaxation energy about 2,793 eV. The Stokes shift based on difference energy absorption and emission calculated about 0,152 eV. Both of this showed phycocyanin can absorbed and radiated the sun light which received. This choice characteristic pigment was a good one related to sensitizer in solar cell application. Integration between light harvesting protein and TiO2 semiconductor surface had important role in improving of output as solar cell materials. The presence of carboxylate group (-COOH) made pigment be more efficient was due to anchored to the surface of TiO2 ampoter. The phycocyanin pigment had carboxylate group which reacted with TiO2 surface formed ester. The carboxylate group increased of dye electronics couple from excited state (p anti bonding orbital) to semiconductor acceptor state (TiO2 conduction band). The samples which made based on annealing temperature variation formed be solar cell respectively. Furthermore, cells be assembled for
