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: Capture fisheries development model for Southern coast of West Jawa province
Abstrak: As mandated in fisheries Act No. 31/2004, the fish resource management target is to improve community welfare especially for the fishers and to conserve the fisheries resources and its environment. The improvement of capture fisheries to be sustainable will be better assured, if all of the main components running capture fisheries in southern coast of West Java Province have never been conducted. This research is aimed to design a capture fishery development pattern integrated in the southern coast of West Java that can be used as a reference to develop the capture fishery by the government also the local community.

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.
