Judul: Evaluasi dan Strategi Pengembangan Tambak Udang Kawasan Minapolitan di Kecamatan Pasir Sakti Kabupaten Lampung Timur
Abstrak: Konsep minapolitan bertujuan untuk mempercepat pembangunan pedesaan di Indonesia dan mengurangi ketimpangan pembangunan antara kota-desa dan urban bias. Salah satu kawasan minapolitan berbasis budidaya di Indonesia berada di Kecamatan Pasir Sakti Kabupaten Lampung Timur dengan komoditi udang vaname. Permasalahan di kawasan minapolitan ini antara lain lemahnya pengelolaan budidaya tambak, keterbatasan lahan bagi pembudidaya tambak sehingga sulit menyerap tenaga kerja bagi masyarakat, informasi pasar yang terbatas, jumlah produksi yang tidak stabil terkadang tidak mampu memenuhi permintaan pasar, dan lembaga keuangan mikro tidak berjalan dengan baik. Penelitian ini bertujuan untuk mengevaluasi program sesuai dengan standar yang ditentukan dari segi kelayakan lingkungan, peran dukungan kelembagaan, sinergitasnya terhadap kebijakan, dan finansial serta menetapkan strategi pengembangan selanjutnya di Kawasan Minapolitan Pasir Sakti. Penelitian yang dilakukan berupa survei kuisioner petani tambak dan ahlinya, dilanjutkan dengan diskusi dengan para ahli untuk menganalisis faktor-faktor yang mempengaruhi perkembangan kawasan minapolitan ini dengan Analisis Internal Factor Evaluation (IFE) dan Evaluation Factor Evaluation (EFE), dan menetapkan strategi pengembangan menggunakan analisis The Quantitative Strategic Planning Method (QSPM). Hasil penelitian ini menunjukkan bahwa Kawasan Minapolitan Tambak Udang Kecamatan Pasir Sakti layak dari aspek sinergitas (84,848%), aspek kelembagaan (75,42), aspek lingkungan (85,82%), dan aspek finansial. Pada hasil analisis strategi, strategi Pengembangan Pasar dinilai efektif bagi pengembangan kawasan minapolitan tambak udang Kecamatan Pasir Sakti. Arahan strategis pengembangan kawasan minapolitan tambak udang Kecamatan Pasir Sakti adalah meningkatkan kualitas dan partisipasi pemangku kepentingan, meningkatkan fasilitas pendukung, mengantisipasi perencanaan kerusakan lingkungan, penegakan hukum, dan meningkatkan sistem budidaya.

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.

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.
