Judul: Strategi Pengelolaan Sumberdaya Perikanan Karang untuk Pemanfaatan yang Berkelanjutan (Kasus: Kepulauan Ayau, Kabupaten Raja Ampat, Provinsi Irian Jaya Barat)
Abstrak: Indonesia failure to get property rights to Sipadan and Ligitan Island represent worth experience about importance of development policy to increase the social welfare in boundries island. Potency consideration and regional specific characteristics is properly placed forward in stimulating of development policy. Ayau Archipelago is one of boundry island in Raja Ampat Regency owning big enough reef fishery potency. Research objective were designed as the strategy of reef fishery resources management for sustainability exploitation in Ayau archipelago, Raja Ampat Regency. SWOT analysis is used to evaluate sustainability of management activities. The sustainability index shows 0,98 which mean reef fishery management activities was unsustain. There were some strategies to anticipate the condition; (1) friendly reef fishery management, (2) optimalization of reef fish potency, (3) development of business system, (4) development of PIR system in business ,(5) development of institution, (6) infrastructure repair of commerce and communication, (7) modernization and motorization of fishing unit, and (8) resource management base on society.

Judul: Pengelolaan Sumberdaya Terumbu Karang Dalam Kawasan Pengembangan Wisata Bahari KKLD Selat Dampier Kabupaten Raja Ampat.
Abstrak: The area of Gam island, Mansuar and Kri of island in the north MPAs of Dampier Strait Raja Ampat regency has potential of coral reef resources for development of marine tourism. The focus management of coral reef to economic rise with management non extractive. The objectives of this research was (a) to analyze the suitability and carrying capacity of coral reef ecosystem for tourism development and (b) to analyze partsipation of stakeholder in management of coral reef resources. The coral reef ecosystem can be used to study its suitability for marine tourism objects of diving. Collected data were life form of coral reef, coral fish, current speed, water transparency and coral reef depth. The formula used to determine tourism suitability is suitability matrix of diving, and Scenic Beauty Estimation (SBE) to judge the quality of landscape. Line intercept transect method showed that islands of Gam, Mansuar and Kri area had a condition of coral reef in the category of “good” with the average coral coverage is 63.75%. However, public participation in the management of coral reefs for the development of marine tourism to has not been done its full potential according to the analysis of community participation.

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.
