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: Pengaruh IPM, Upah Minimum, Belanja Pendidikan dan Kesehatan terhadap Kemiskinan di Provinsi Jawa Barat (Periode Tahun 2016-2019)
Abstrak: Kemiskinan adalah salah satu masalah dalam perekonomian Indonesia yang kompleks dan mendasar. Perlu dicari solusi untuk mengatasi atau paling tidak mengurangi tingkat kemiskinan. Penelitian ini dilakukan untuk mengetahui variabel IPM, upah minimum, belanja pendidikan dan kesehatan terhadap tingkat kemiskinan di Provinsi Jawa Barat sebagai variabel terikat. Metode analisis yang digunakan adalah analisis deskriptif dan analisis regresi linear berganda data panel. Data yang digunakan adalah data 27 kabupaten/kota di Provinsi Jawa Barat selama periode tahun 2016 – 2019. Hasil penelitian menunjukkan bahwa secara simultan, IPM, upah minimum, belanja pendidikan dan belanja kesehatan mempunyai pengaruh yang signifikan terhadap pengangguran terdidik. Secara parsial, IPM, upah minimum dan belanja kesehatan berpengaruh negatif sedangkan belanja pendidikan berpengaruh positif terhadap kemiskinan di Provinsi Jawa Barat., Poverty is one of the problems in Indonesia's economy which is complex and fundamental. It is necessary to find a solution to overcome or at least reduce the level of poverty. This study was conducted to determine the variable HDI, minimum wage, education and health spending on the poverty level in West Java Province as the dependent variable. The analytical method used is descriptive analysis and multiple linear regression analysis of panel data. The data used is data from 27 districts/cities in West Java Province during the period 2016 – 2019. The results show that simultaneously, HDI, minimum wages, education spending and health spending have a significant influence on educated unemployment. Partially, HDI, minimum wages and health spending have a negative effect, while education spending has a positive effect on poverty in West Java Province.

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.
