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: 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.
