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: 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: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
