Judul: Dampak kebijakan ekonomi makro terhadap pendapatan nasional dan ekspor pertanian Indonesia
Abstrak: Pemilihan topik penelitian ini didasarkan atas perkembangan ekonomi Indonesia yang makin gencar menggalakkan ekspor non migas termasuk ekspor pertanian guna mengimbangi turunnya harga minyak bumi di pasaran dunia. Alat analisis yang digunakan dalam penelitian ini adalah model makroekonometrik yang menggabungkan sektor riil dan sektor moneter dan terdiri dari 24 persamaan. Estimasi parameter dilakukan dengan metode Non Linear Three Stage Least Squares (N3SLS), sedangkan evaluasi kebijakan didasarkan atas nilai impact elasticities yang diperoleh dari simulasi historis. Hasil simulasi menunjukkan bahwa kebijakan uang longgar akan meningkatkan pendapatan nasional dan ekspor pertanian, tetapi diimbangi oleh tingkat inflasi yang tinggi. Devaluasi dan peningkatan pinjaman luar negeri akan meningkatkan pendapatan nasional dan ekspor pertanian hanya pada tahun pertama saja, pada tahun-tahun berikutnya kebijakan tersebut justru akan berpengaruh negatif.

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.
