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 Investasi terhadap Pertumbuhan Ekonomi Regional di Indonesia
Abstrak: Pemerintahan Jokowi-JK meluncurkan 16 paket kebijakan ekonomi yang diharapkan meningkatkan investasi baik Penanaman Modal Asing (PMA) dan Penanaman Modal Dalam Negeri (PMDN) setiap wilayah di Indonesia. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi investasi baik PMA maupun PMDN serta pengaruh PMA dan PMDN terhadap pertumbuhan ekonomi regional di Indonesia. Data yang digunakan berupa data panel 34 provinsi di Indonesia selama 2015-2018. Metode yang digunakan dalam penelitian ini adalah analisis deskriptif dan kuantitatif berupa data panel menggunakan Fixed Effect Model (FEM). Hasil penelitian memperlihatkan bahwa pertumbuhan ekonomi, laju pertumbuhan ekonomi, ekspor-impor dan angkatan kerja terbukti memengaruhi PMA dan PMDN. Selain itu, PMA, PMDN, angkatan kerja dan ekspor berpengaruh positif dan signifikan terhadap pertumbuhan ekonomi sedangkan impor berpengaruh negatif namun tidak signifikan. Pemerintah perlu melakukan pemerataan pertumbuhan ekonomi, ekspor-impor, angkatan kerja serta stabilisasi laju pertumbuhan ekonomi untuk meningkatkan PMA dan PMDN setiap wilayah di Indonesia. PMA dan PMDN diharapkan dapat diarahkan ke sektor potensial masing-masing wilayah 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.
