Judul: Analysis of capture fisheries development in South Sumatera province
Abstrak: Marine and fisheries sectors in South Sumatera Province is one of the leading economic sector. The development is expected to improve the welfare of fishermen, to absorb labor and increase revenue and ensure its sustainability in the future. The purpose of this research is to develop design based fishery development of sustainable business in South Sumatera Province. The research method used is survey method with several data analysis tools such as surplus production method, scoring method, multi-criteria analysis, SWOT analysis and Analytical Hierarchy Process (AHP). Kinds and the potential yield commodities of fish in South Sumatera Province are shrimp (Penaeid) of 6297.98 tons; 1955.98 tonnes of blue swimmer crabs (Portunus spp); catfish (Arius thalassinus) amounted to 4488.06 tons and machete (Chirosentrus dorab) at 3718.69 tons. Type of fishing gears that still more likely to be increased are trammel nets, drift gill nets, fixed gill nets and encircling gillnets. The main priority of the alternative strategy of fisheries development policy in South Sumatera Province by improving the facilities and operational infrastructure to support the fishing effort. This is possible considering that the development of fisheries in South Sumatera has a substantial dependence on such facilities and infrastructure problems. Support of infrastructure facilities and good support, activities of both capture fisheries, processing and marketing can be more efficient and become an important point to increase the benefits of fishery products in South Sumatera Province.

Judul: System development for capture fisheries business of Riau Province
Abstrak: The general objectives of this research is to develop system development of capture fisheries business in Riau Province which can be used as referrence in capture fisheries development planning after experiencing expansion of administrative areas. To achieve these general objective, and more specifically the special purpose of this study are; 1) determine the proper capture fisheries business to develop; 2) determine the appropriate conflict resolution; 3) the appropriate institutional form in the development of capture fisheries business. Survey method was used to collecting information and data from the field. Schaefer model was used to determine the limit of fishery utilization by determining the Maximum Sustainable Yield ( MSY). Linear Goal Programming Model was used to analyze the technological allocation based on all determined target. Scoring method was applied to determine the best kind of capture fisheries technology. Quantitative and qualitative analysis were used for economic and social aspect and descriptive analysis to determine the environmental friendly fishing technology. Method of conflict resolution techniques based on Fisher et al. (2000). The results indicated that selected fish resource in Malacca Strait Bengkalis Regency are, yellow pike-conger (Congresox talabon), giant threadfish (Eleutheronema tetradactylum), silver pomfret (Pampus argenteus), and white shrimp (Metapenaeus sp), with fishing technology of longline, batu net, atom net and apollo net. The optimum amount for the selected fishing technology in Bengkalis Regency is 6595 unit. Selected fish resources in the South China Sea Indragiri Hilir Regency are giant threadfish (Eleutheronema tetradactylum)”, white shrimp (Metapenaeus sp), yellow pike-conger (Congresox talabon) and barred spanish mackerel (Scomberomorus commersoni) and with fishing technology of longline, “batu net”, gillnet and shrimp net. The optimum amount for the selected fishing technology in Indragiri Hilir Regency is 5956 unit. Conflict in the waters of Bengkalis is the conflict between longline fishermen and batu net fishermen. Identification for the conflict typology based on internal allocation and jurisdiction. Strategic planning that can be done to resolve conflicts in these waters is the involvement of fishing communities, especially community leaders in the utilization and management, formal recognition of sea tenure in the community in resource management and increased surveillance conducted in an integrated manner, which involves all elements in System Development for Capture Fisheries Business of Riau Province (SIPUTREFIK) and the establisment of institutional mediators.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
