Judul: Pengaruh Kualitas Pendidikan Tenaga Kerja Terhadap Pertumbuhan Ekonomi Regional: Analisis Data Provinsi Di Indonesia 2009-2013.
Abstrak: Pertumbuhan ekonomi regional dipengaruhi oleh beberapa faktor antara lain tingkat pendidikan, jumlah tenaga kerja, jumlah penduduk dan kapital. Pendidikan memiliki peranan penting dalam meningkatkan kualitas tenaga kerja. Penelitian ini dilakukan untuk menganalisis pengaruh kualitas pendidikan tenaga kerja terhadap pertumbuhan ekonomi regional di Indonesia. Data yang digunakan adalah data sekunder dari 33 provinsi di Indonesia dengan periode tahun 2009 sampai dengan tahun 2013. Penelitian ini menggunakan dua metode yaitu metode deskriptif dan analisis kuantitatif panel dengan Fixed Effect Model. Hasil penelitian menunjukkan bahwa tingkat pendidikan dan kapital berpengaruh positif secara signifikan terhadap pertumbuhan ekonomi regional di Indonesia. Jumlah penduduk berpengaruh signifikan negatif dan jumlah tenaga kerja tidak signifikan terhadap pertumbuhan ekonomi regional di Indonesia.

Judul: Analysis of the Impact of Capital and Labor on the Regional Economy in Indonesia
Abstrak: Perekonomian regional merupakan proses dimana pemerintah daerah bersama masyarakat berusaha untuk mengelola sumber daya dan membentuk kerja sama untuk memajukan perekonomian. Menurut teori neo klasik, modal dan tenaga kerja termasuk dalam faktor-faktor produksi yang memengaruhi perkembangan perekonomian regional. Hingga saat ini, struktur perekonomian Indonesia masih didominasi oleh Pulau Jawa. Penelitian ini bertujuan untuk mendeskripsikan kondisi perekonomian regional dan menganalisis pengaruh investasi domestik, investasi luar negeri, infrastruktur listrik, infrastruktur kesehatan, dan tenaga kerja terhadap perekonomian regional di Indonesia selama periode 2010-2021. Metode analisis yang digunakan dalam penelitian ini adalah analisis deskriptif dan analisis data panel. Hasil estimasi data panel menunjukkan bahwa investasi domestik, investasi luar negeri, infrastruktur listrik, infrastruktur kesehatan, dan tenaga kerja secara signfikan berpengaruh positif terhadap perekonomian regional di Indonesia. Tenaga kerja menjadi variabel yang paling kecil dalam memengaruhi perekonomian regional karena adanya kaitan dengan pengangguran dan perubahan struktur ekonomi., The regional economy is a process where local governments and communities try to manage resources and form partnerships to advance the economy. According to the neo-classical theory, capital and labor are included in the factors of production that impact regional economic development. Until now, the structure of the Indonesian economy is still dominated by Java. This study aims to describe the condition of the regional economy and analyze the impact of domestic investment, foreign investment, electricity infrastructure, health infrastructure, and labor to the regional economy in Indonesia during the 2010-2021 period. The analytical method used in this research is descriptive analysis and panel data analysis. The panel data estimation results show that domestic investment, foreign investment, electricity infrastructure, health infrastructure, and labor have a significant positive effect on the regional economy in Indonesia. Labor is the smallest variable affecting the regional economy because of its connection with unemployment and changes in economic structure.

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.
