Judul: Faktor-Faktor yang Memengaruhi Penawaran Ekspor Karet Alam dan KrustaseaIndonesia ke Jepang.
Abstrak: Hubungan kerjasama ekonomi antara Indonesia dengan Jepangmelalui pelaksanaanIndonesia-Japan Economic Partnership Agreement (IJEPA)dimulai pada tahun 2008. Pada tahun 2011 sampai 2015, neraca perdagangan Indonesia dengan Jepang mengalami defisit pada sektor nonmigas. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi penawaran ekspor karet alam dan krustasea di Jepang dan implikasi kebijakan yang mampu meningkatkan ekspor.Metode yang digunakan adalah Ordinary Least Square (OLS) dengan periode data tahun 1994 sampai 2015. Hasil penelitian menunjukan bahwa nilai ekspor karet alam Indonesia ke Jepang dipengaruhi oleh harga ekspor karet alam, produksi karet alam domestik, populasi Jepang, dan GDP Jepang. Serta, nilai ekspor krustasea Indonesia ke Jepang dipengaruhi oleh harga ekspor krustasea, produksi krustasea domestik, populasi Jepang, dan dummy pemberlakuan kerjasama IJEPA.

Judul: Indonesian Natural Rubber Export to Japan and Its Determinants
Abstrak: Karet alam merupakan salah satu komoditas perkebunan unggulan Indonesia yang sebagian besar ditujukan untuk kegiatan ekspor. Kinerja ekspor karet alam Indonesia ke beberapa negara tujuan utama mengalami tren penurunan selama periode 2011-2019. Jepang merupakan salah satu negara tujuan utama ekspor karet alam Indonesia yang mengalami tren penurunan nilai ekspor. Penelitian ini bertujuan untuk menganalisis ekspor karet alam Indonesia ke Jepang dan faktor-faktor yang memengaruhinya selama periode 2011-2019 dengan menggunakan metode deskriptif kualitatif dan Error Correction Model (ECM). Hasil penelitian menunjukkan harga karet alam dunia dan penerapan kebijakan AETS berpengaruh signifikan terhadap nilai ekspor karet alam Indonesia ke Jepang dalam jangka panjang. Hasil penelitian juga menunjukkan bahwa nilai tukar rupiah terhadap dollar Amerika Serikat berpengaruh signifikan terhadap nilai ekspor karet alam Indonesia ke Jepang dalam jangka pendek. Indonesia perlu meningkatkan kualitas produksi dan produktivitas lahan karet alam serta memperbaiki kinerja industri hilir karet agar dapat meningkatkan kinerja ekspor karet alam Indonesia ke Jepang., Natural rubber is one of Indonesia's leading plantation commodities, which is mainly intended for export activities. The export performance of Indonesian natural rubber to several destination countries experienced a downward trend during the 2011-2019 period. Japan is one of the leading export destinations for Indonesian natural rubber, which experienced a downward trend in export value. This study aims to analyze Indonesian natural rubber exports to Japan and its determinant factors during the 2011-2019 period using descriptive qualitative and the Error Correction Model (ECM) method. The results show that the natural rubber price and the implementation of AETS policy had significant effect on the export value of Indonesian natural rubber to Japan, in the long term. The results also show that the rupiah exchange rate against the US dollar had significant effect in the short term. Indonesia needs to improve the quality of natural rubber production and productivity as well as improve the rubber industry performance to increase the performance of Indonesian natural rubber export to Japan.

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.
