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: Strategi Pengembangan Perikanan Pancing Ramah Lingkungan di  Kabupaten Raja Ampat Papua Barat
Abstrak: Nelayan pancing di Kabupaten Raja Ampat menghadapi kesulitan dalam mengembangkan usahanya. Kesulitan tersebut disebabkan oleh tidak adanya pangkalan pendaratan ikan dan tingginya harga BBM, pengelolaan usaha masih tradisional, armada yang tidak memadai, serta ancaman Illegal Unreported Unregulated (IUU) fishing dan destruktif fishing pada sumber daya ikan. Penelitian ini dianalisis menggunakan metode SWOT yang bertujuan untuk menentukan konsep strategi yang mendukung pengembangan perikanan pancing ramah lingkungan di Kabupaten Raja Ampat. Strategi yang diperoleh diantaranya optimalisasi kearifan lokal sasi, membangun fasilitas perbekalan melaut, dan penguatan armada penangkapan lokal. Selain itu, untuk mengatasi IUU fishing dan destruktif fishing perlunya tambahan armada patroli dan optimalisasi keterlibatan masyarakat dan nelayan dalam upaya konservasi. Pemkab Raja Ampat dan KKP melalui program COREMAP mengadakan pembinaan dan pelatihan secara rutin terkait mata pencaharian alternatif bagi nelayan., Line fishermans in Raja Ampat Regency have faced difficulties to develop their own marine fisheries. These difficulties is caused by unavailability of fish landing base and the high prices of fuel. The fisheries management is still traditional, insufficient fleet, and Illegal Unreported Unregulated (IUU) fishing and destructive fishing to the fish resources. The aim of this research is to determine the supporting concept and strategy to support environmentally line fishing in Raja Ampat Regency. The SWOT (Strength Weakness Opportunity Threats) concept is used to determine the environmentally line fishing. One of the obtained is optimize local wisdom “sasi”, building fish landing base and fishing supplies facility, and enpowering of local fishing fleet. On the other hand, to solve the IUU fishing and destructive fishing, the patrol fleet is added by optimize the society and fisherman involvement is held by COREMAP to fulfill the conservation effort. The government of Raja Ampat and Ministry of Fishing and Marine on COREMAP frame by conducting the daily training for local fishermans and society about alternative livelihood.

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.
