Judul: Strategi Pengembangan Kawasan Perikanan Budidaya di Kabupaten Lampung Timur
Abstrak: Lampung Timur regency set to minapolitan area in 2010 as the implementation of the strategic plan of The Marine and Fisheries Affairs Ministry to make Indonesia as the largest producer of fishery products in the world in 2015. Planning aquaculture development strategy becomes important so that the existing fishery resources can be utilized optimally and efficiently. The objectives of this study are to identify the prime aquaculture commodities, to evaluate land suitability, mapping the direction of the aquaculture development and planning strategies for developing aquaculture in Lampung Timur regency. Margin value analysis results, productivity trends, harvested area trends, demand analysis and preference analysis shows that the seaweed and green mussel is the pre-eminent commodity in sea farming while vaname, tiger shrimp and milkfish is the pre-eminent commodity in brackish water aquaculture and tilapia, catfish and gurame is the pre-eminent comodities in freshwater aquaculture at Lampung Timur regency.. Land suitability analysis for sea farming activity in East Lampung regency explained that 50.71% of sea area have a very suitable criteria (S1), 23.53% suitable (S2), 24.26% less suitable (S3) and 1.5% are not suitable (N). land suitability analysis for brackish water aquaculture resulted of 14.14% have a very appropriate criteria (S1), 46.21% suitable (S2), 26.89% less suitable (S3) and 12.77% were not suitable (N). While land suitability for the fresh water aquaculture resulted only 0,05% has very suitable criteria (S1), suitable 72.45% (S1), 22.41% less suitable (S3) and 5,09% are not suitable (N). The development of sea farming is directed on marine areas along the coast of Lampung Timur Regency area of 38 871 ha, while for brackish water aquaculture development is directed at two districts namely Labuhan Maringgai and Pasir Sakti with vaname commodity area of 2 966 ha, black tiger shrimp covering 9 880 ha, milkfish area of 3 833 ha and 1 382 Ha of ponds located in coastal border is directed for fishforetry of milkfish or shrimp. Freshwater aquaculture development is directed at an area of 53 304 ha that spreading over 8 districts i.e. Bumi Agung, Batanghari, Sekampung, Raman Utara, Purbolinggo, Way Bungur, Way Jepara, and Jabung, with backyard fishpond pattern for the development of catfish aquaculture, serene ponds water for gurame and mina padi for tilapia development. While bamboo cages and floating cages developed for all three fishes. Alternative strategy that could be pursued are to improve the quality of knowledge-based human resources, improving institutional farmers, improving marketing institutions and improve the provision of facilities and infrastructure.

Judul: Analisis potensi dan pengelolaan perikanan dalam perspektif ketahanan pangan di wilayah pesisir Kabupaten Lampung Barat
Abstrak: Fish as a nutritious foodstuff with high protein and essential amino acids is neeff{t by human beings for growth and intelligence. Therefore, it is necessary for the ~vernment to make sure the availability offish for the people's consumption. The ~astal zone of West Lampung Regency is rich in fishery resources potential; however, the utilization has not been optimum yet. In line with this, it is "tI impQtant to fonnulate a good strategy to achieve optimum and sustainable fishe!.ies management. The aim of this study was to analyze the potential resom-ces and management of fisheries during the periods of 2003-2007 at the coasil zone of West Lampung. This study was to collect primary and secondary data~at were analyzed using SWOT. SWOT analysis is a technique used to idenSfy various factors systematically in order to fonnulate a management strat~y. SWOT analysis is based on the reasoning to maximize the strengths and opp<!tunities, and at the same time to minimize the weaknesses and threats. The resu@! showed that the total score for internal factor (strengths-weaknesses) was 0.23~d the total score for external factor was -0.32 (opportunities-threats); whici placed the fisheries management at the coastal zone of West Lampung rege~y in the second quadrant position. This meant that the support for condticting a diversification strategy, in which strengths are used to deal with threats. The priority of alternative strategy carried out for optimum and sustainable fisheries management was to develop aquaculture (fresh water and estuary), to resolve conflicts of interest on natural resources used at the coastal zone of West Lampung, and to improve the involvement of fonnal and non fonnal institutions in implementing environment friendly efforts as well as in resolving environmental degradation problems.

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.
