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: 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: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
