Judul: Economic Analysis of Policy Making on Chondrichtyans Fishing Prohibition in Berau Regency, East Kalimantan (Case Study : The Derawan Archipelago).
Abstrak: Berau is one of the region that equipped with marine natural wealth. Since a long time, local people has been utilizing sea products as their livelihood. While in recent years, government of the region is focusing on the development of coastal and marine tourism as it projected to bring more sustainable benefit to the society. In the effort of making the plan works, the government has establish a temporary policy ; to prohibit all activity that related to sharks and rays fishing. However, there are a few stakeholders objected the newly made rule. In order to assuring the effectiveness of the plan and to minimize the negative impact burdened to few stakeholders, designing a new policy proposal is felt necessary. The objective of study are 1) to estimate the components that will be affected by the new policy, 2) to find an appropriate policy alternative, 3) to estimate and decide which policy alternative brings the biggest net benefit, and 4) to analyze the best implementation strategy. This study implement the Regulatory Impact Assessment (RIA) framework, adopted from Indonesian Development Planning Agency (Bappenas) and Organization Economic Co-Operation and Development (OECD). The method that has been used in this study are productivity approach, economic multiplier impact calculation, exponential comparison method, cost – benefit analysis, and CIPP evaluation model. The components that are impacted divided into two industry; fisheries and tourism. The fisheries industry actual value is IDR 750,653,298 per month with the productivity rate of 16.92. The tourism industry brings the total value of Rp 35,067,076,021 per month with the value of Keynessian Income Multiplier of 0.47, value of Ratio Income Multiplier (1st type) is 1.44, and value of Ratio Income Multiplier (2nd type) is 1.48. From the application of ECM, it is founded that the most promising policy is to prohibit all fishing activity of conserved (listed) species only. After calculating the cost benefit-analysis, the chosen policy brings Rp 2,567,588,022,919 after twenty five (25) years of policy implementation. Completing the objectives, according to CIPP method the strategy that are needed is to provide another policies, opportunities, development, and studies that support the concept of Sustainable Goals of Berau Regency.

Judul: Economic Analysis of Sustainable Management of Fisheries Effort in Indramayu Regency
Abstrak: As an archipelagic country, Indonesia has territorial water at 5,8 million km2 Method of this research are biological analysis, bio-economical model, economic interest analysis, economic intensity analysis, and strategic analysis with use analytical hierarchy process (AHP). Fish resources with potential and become main products of fishermen in Indramayu Regency Indramayu are manyung, tenggiri, peperek, kembung, and tongkol. The production of fifth fish species about 85,6 % from fish production total in territorial water of Indramayu Regency. Maximum stock capacities (MSY) of manyung, tenggiri, peperek, kembung, dan tongkol in territorial water of Indramayu Regency each are 1291,37 ton/year, 1120,70 ton/year, 4227,93 ton/year, 1135,76 ton/year, and 5343,58 ton/year. Maximum economic yield (MEY) of manyung, tenggiri, peperek, kembung, and tongkol in territorial water of Indramayu Regency each are Rp 16.471.401.174/tahun, Rp 31.745.619.591/tahun, Rp 54.907.433.923/tahun, Rp 9.911.840.550/tahun, and Rp 42.547.409.047/tahun. consisted about 17.504 islands and coastal line more 81.000 km with various of fish resource. According to DPK of Indramayu Regency (2010a), the production of sea fishery in Regency of Indramayu is stable at 2009 reaching 108.554,6 ton with value about Rp 1.383.687.650.000. That production must influence stock capacities of fish resources in fishing ground, so that its exploiting require to be controlled, inclusive maximum economic yield (MEY). The aim of the research to analyse stock capacities and maximum economic yield of fisheries resources, to analyse sustainability of fisheries effort, and to formulate the development strategic of sustainable economic based on fisheries effort in Indramayu Regency. Drift gillnet (JIH), set gillnet (JIT), payang, bottom long line, handline, dan shrimp gillnet (JK) can be laboured on an ongoing basis in Indramayu Regency. Economi interest of drift gillnet (JIH), set gillnet (JIT), payang, bottom long line, handline, dan shrimp gillnet (JK) each are Rp1.029.134.326, Rp 579.915.247, Rp 992.640.822, Rp 263.338.992, Rp 56.725.341, dan Rp 76.184.501. Return of return of drift gillnet (JIH), set gillnet (JIT), payang, bottom long line, handline, dan shrimp gillnet (JK) each are 42,01 %, 31,35 %, 56,72 %, 58,52 %, 66,74 %, dan 43,53 %. Development strategic of sustainable economic based on fisheries effort in Indramayu Regency from priority most important to less be important are ; (a) Repair of management of fisheries effort (RK = 0,255, II = 0,05), (b) Construction of human resources of fisheries sector (RK = 0,230, II = 0,05), (c) Development of capitalization cooperation (RK = 0,193, II = 0,05), (d) Development of scale small fisheries ( RK = 0,186, II = 0,05), and (e) Development of supporting units of fisheries effort (RK = 0,136, II = 0,05).
