Judul: Analisis administrasi program gerakan nasional rehabilitasi hutan dan lahan (GNRHL/ Gerhan)
Abstrak: Program Gerakan Nasional Rehabilitasi Hutan dan Lahan (GNRHL/ Gerhan) merupakan salah satu upaya pemerintah untuk mengatasi kerusakan hutan dan lahan yang terjadi di Indonesia. Program tersebut merupakan gerakan rehabilitasi yang melibatkan banyak pihak dalam pelaksanaannya. Pihak yang terlibat terdiri dari Pemerintah Pusat, Pemerintah Daerah, LSM, instansi terkait, dan masyarakat. Meski telah melibatkan banyak pihak, namun tujuan dari program tersebut untuk merehabilitasi hutan dan lahan belum sepenuhnya terlaksana. Untuk itu diperlukan analisis terhadap program tersebut.

Judul: Performance Analysis of National Forest and Land Rehabilitation Movement (GERHAN) in Ambon
Abstrak: Critical land areas increasing vast by year accros Indonesia because of forest and land degradation. Those phenomenon and its negative impact also happened in the Province of Moluccas. Critical land occupied 59.24% from the total area of Moluccas. Due to this situation, since 2004 Indonesian Ministry of Forestry made Moluccas as one of the priority target for GERHAN. This study aimed to analyze the technical, sosioeconomics, and institutional aspect of GERHAN, analyze factors that cause fluctuations on GERHAN achievment, and formulate a stategic recomendations for the future implementation of forest and land rehabilitation. The study used an evaluation approach by comparing the implementation of GERHAN at Moluccas with a standard performances for GERHAN setting up by Indonesian Ministry of Forestry. Study result showed that GERHAN were carried out on three types of tenure, wich is private land, clans land, and state forest area. The community whose join the program generally did not understand the technical aspect, especially in the planning stages. From financial point of view referring to the analysis of BCR, NPV, and IRR, using 15% interest rate and 30 years as a program period, GERHAN are feasible on all typologies, with first typology as an exception. The failure of investment in GERHAN mainly caused by forest fire and without any involvement from the local institutions. The farmer institusion is ad hoc and not permanent.

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.
