Judul: Pengelolaan Ekosistem Terumbu Karang di Daerah Perlindungan Laut di Pulau Kaledupa Kabupaten Wakatobi
Abstrak: The study concerned to analyze the management of coral reef ecosystems in Marine Protected Areas (MPAs) Kaledupa Wakatobi. The used analytical frame work of Institutional Analysis and Development (IAD), development institutional concerd IAD is used to analyze the performance and structure of the management institutional MPAs. This will be evaluated by ecological, social, and institutional (rules used). Ecological aspects represented by changes in life of coral cover on the date of and after the MPAs formed, the social aspect is represented by the condition of society and people's perceptions, institutional aspect will focus on rules that used in the institutional structure and performance. The results showed that the location of the general conditions study and life of coral cover have decreased in the early establishment by 35.5% -51.3% (medium-well) to 17.2% -39.9% (broken-being) after MPAs runs. The decline was caused by the activities of overfishing and the use of fishing tools that are not environmentally friendly. From the institutional aspect, still can’t protect the resources. This can be seen from the surveillance sistem which is weak, the punishment didn’t work properly, and so the rules haven’t fully accepted by society.

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.
