Abstrak: The declining trend of catch fishery production and increasing demand for fishery products, requires efforts to increase production by taking into account aspects of sustainable living. Hulu Sungai Utara Regency has a swamp land reached 63% of the potential total area that can developed for marsh fishing activities. The purpose of this study are: (1) to identify areas of fishery activities on the basis of comparative advantage, (2) to identify the causes of decline in fishery production, (3) to identify the fishery reserves to sustain fishing activities, (4) to identify the perceptions of stakeholders about the direction of the development potential nontidal swamps fishery, and (5) to formulate strategies and policy priorities as the development direction of nontidal swamps fishing potential in Hulu Sungai Utara Regency. The data analysis were used descriptive analysis, analysis of the technical criteria of fishery reserves, spatial analysis, Location Quotient (LQ), Analytical Hierarchy Process (AHP) and SWOT analysis. The results showed that the basis of fishing activities based on comparative advantage is Danau Panggang district, Sungai Pandan district, Amuntai Selatan district, Amuntai Utara district dan Sungai Tabukan district. Decline in fish production due to low utilization of the potential of fishery resources. The fishery reserves located in sub district Tampakang, Pal Batu, Pandamaan, Baru, Pajukungan Hilir, Sungai Dalam, Teluk Limbung, Sungai Durait Hilir, Sungai Durait Tengah, Danau Cermin, Pulau Tambak dan Banyu Hirang. The perception of stakeholders on the nontidal swamps fishery management’s is the priority of physical factors followed by social and institutional factors and the recent economic factors. Based on the SWOT analysis, the recommended policy priorities to be implemented is the use of natural resources, fish resources, human resources, facilities and infrastructure, market potential and capital to increase production and profits. The fishery area which can be exploited area 24.790 hectares scattered throughout the district, while the fishery reserves covering 1.775,6 hectares.

Judul: Potensi pengembangan lahan rawa lebak untuk perluasan lahan padi di Kabupaten Hulu Sungai Utara Kalimantan Selatan
Abstrak: Agricultural development has an important position for national food security. Increased food security is pursued through the improvement of rice production. The island of Java as the biggest rice producers continue to decrease in size field rice area, so another rice field alternative outside of Java is needed. One of them is nontidal swamp land that is still very wide, such as in Hulu Sungai Utara District South Kalimantan Province. The purpose of this study was to identify suitable land for paddy cultivation and development as well as conservation areas to safeguard the sustainability of farming, knowing the center of rice production and priority directions of development policy. Identify potential rice field using land suitability analysis by remote sensing data and processing data done in ArcGIS 9.3. Land suitability analysis using ArcGIS 9.3 with reference to the criteria established by the Department of Agriculture. Conservation area determined by reference to the Presidential Decree 32 of year 1990 on protected areas. Potential development for rice field is done by overlay spesific analysis of land suitability result and existing landuse are interpreted from the ALOS AVNIR, Landsat and Google Earth images. Centralization of activities carried out by Location Quetion Analysis and policy priorities with SWOT Analysis. The results showed that the potential development of land for rice field is still very widespread, especially in Danau Panggang Subdistrict and Paminggir Subdistrict. Peatland conservation areas are in northern and lake buffer areas in Danau Panggang Subdistrict . River buffer areas spread across the district. Policy priorities are directed to the appropriate utilization of the potential area for rice in the base region with the expansion of paddy fields.

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.
