Judul: Analisis Dinamika Korupsi dan Transparansi dalam Model Pertumbuhan Ekonomi Neoklasik
Abstrak: Corruption is one of big issues being faced by many countries in the world. The objectives of this research are to analyze: the effect of corruption to growth economy factors, and the relationship between corruption and transparency in economic institutions using Ramsey and Cobb Douglas models. There are three main resources of corruption, namely tax, output and consumption. The tax sector is the most corrupted resources. Corruption causes high cost economy that increases discount rates and depreciation. Consequently levels of investments, accumulated public capital and output in the long run will be declined. As a convergent system, it has a negative relationship between the level of corruption as endogenous variable and the growth rate of output. The prediction of this model matches with the current empirical evidence on the relationship between the growth rate of output, corruption, public investment and fiscal transparency

Judul: Pengaruh Kebijakan Fiskal Terhadap Pertumbuhan Ekonomi Dalam Model Neoklasik
Abstrak: Pertumbuhan ekonomi jangka panjang merupakan pertumbuhan output riil perekonomian suatu negara. Pemerintah dapat mengatur kebijakan fiskal untuk meningkatkan pertumbuhan ekonomi. Tujuan karya ilmiah ini ialah menganalisis pengaruh kebijakan fiskal yang berupa tingkat pajak dan komposisi pengeluaran pemerintah terhadap output per kapita saat kondisi steady state dan pertumbuhan ekonomi pada masa transisi. Model neoklasik suatu perekonomian akan mencapai kondisi konstan apabila modal per kapita mencapai tingkat yang stabil dan fungsi kesejahteraan sosial maksimum. Bagian simulasi karya ilmiah ini menunjukkan bahwa pengaruh tingkat pajak dan komposisi pengeluaran pemerintah terhadap pertumbuhan ekonomi adalah tidak monoton. Selain itu, nilai pajak dan komposisi pengeluaran pemerintah dapat mengoptimumkan nilai output per kapita dan tingkat pertumbuhan ekonomi.

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.
