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: Pemetaan Komponen Indeks Pembangunan Manusia dan Tingkat Kemiskinan di Jawa Barat Menggunakan Regresi Data Panel
Abstrak: Sebagai salah satu provinsi dengan jumlah penduduk terbesar di Indonesia, Provinsi Jawa Barat berkomitmen mengatasi berbagai persoalan yang ada demi tercapainya target pembangunan berkelanjutan, terutama dalam menangani masalah kemiskinan. Kemiskinan di Indonesia dapat digambarkan oleh berbagai faktor, salah satunya yaitu Indeks Pembangunan Manusia (IPM) dan indikator-indikator penyusunnya. Penelitian ini menggunakan data dari Badan Pusat Statistik Provinsi Jawa Barat yang dianalisis dengan metode analisis regresi data panel. Regresi data panel sangat cocok digunakan pada data yang mempunyai pengaruh individu dan pengaruh waktu. Penelitian ini bertujuan untuk mendapatkan gambaran kecenderungan hubungan rata-rata lama sekolah, harapan lama sekolah, angka harapan hidup, dan pengeluaran per kapita sebagai penyusun Indeks Pembangunan Manusia dengan persentase penduduk miskin di Jawa Barat. Hasil yang diperoleh menunjukkan bahwa indikator penyusun Indeks Pembangunan Manusia memiliki karakteristik yang berbeda. Harapan lama sekolah menunjukkan pola searah, sedangkan pengeluaran per kapita, rata-rata lama sekolah, dan angka harapan hidup memiliki pola hubungan yang negatif terhadap persentase kemiskinan di Jawa Barat., As one of the provinces with the largest population in Indonesia, West Java Province is committed to overcoming various existing problems to achieve sustainable development goals, especially in addressing the issue of poverty. Poverty in Indonesia can be described by multiple factors, including the Human Development Index (HDI) and its indicators. This study uses data from the Statistics Indonesia West Java Province, and its be analyzed using panel data regression analysis methods. The panel data regression is very suitable for use on data that has individual and time effects. This study aims to get a picture of the trend of the relationship between average length of schooling, expected length of schooling, life expectancy, and per capita expenditure as components of the Human Development Index with the percentage of poor people in West Java. The results obtained show that the indicators of the Human Development Index have different characteristics. Expected length of schooling shows a unidirectional pattern, while per capita expenditure, average length of schooling, and life expectancy have a negative relationship pattern with the percentage of poverty in West Java.

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.
