Judul: Prospek pemasaran dan strategi pengembangan produk olahan hasil perikanan di Dki Jakarta (studi kasus ikan asin dan pindang)
Abstrak: Ministry of Marine Affairs and Fisheries Republic of Indonesia continues to develop a variety of efforts to make Indonesia as the world’s largest fisheries producer in 2015, center of which are encouraged through the development of fisheries to increase the value-added. This studi aim to : (1) Analyzing the condition and prospects of the marketing management of fisheries products processd in Jakarta; (2) Analyze the financial feasibility level processing business management and marketing of fisheries products in Jakarta; (3) Formulate the development strategy of fisheries products processed in Jakarta. This study uses primary data (observations and interviews in the field) and secondary data (literature and consulting experts) with the processing techniques and data analysis using the Strength Weakness Opportunities Threats (SWOT) analysis, Internal Factor Evaluation (IFE), External Factor Evaluation (EFE), Internal External (IE) and Analitycal Hierarchy Process (AHP). The results of these studies show : (1) Management of marketing of fisheries products processed salted and boiled fish species is currently in Jakarta is in a stable growth conditions (quadrant matrix V on the IE-SWOT). The total score of the internal factors of marketing management of fisheries products processed from salted and boiled fish species (2,58), and total score of the external factor about 2,54 (in the range 2-3 midle), so the prospect for future development to include the category “reasonably good”; (2) Business japuh salted fish, salted stingrays, and jambal salted fish, selar boiled fish, tuna boiled fish and etem boiled fish including viable developed further in the center for fisheries Jakarta, because it has a value NPV > 0, IRR > 14% (commercial interest rates), ROI > 1, and B/C ratio > 1. Business salted anchovy and boiled fish kite is not worth further developed because it has a lower value IRR and B/C ratio than the standards required. Value of IRR business salted anchovy and boiled fish kite in center for fisheries Jakarta respectively 4,22% and 9,13%, and value of B/C ratio respectively 1,00; (3) Product development strategy of processed fisheries product from fish species of salted and boiled in Jakarta consecutive based on priorities, diversification strategy (RK = 0,267), expansion strategy (RK = 0,220), combination strategy (RK = 0,191), stability strategy (RK = 0,174) and downsizing strategy (RK = 0,146). Inconsistency of priority sequence has a 0,06 so it can be trusted. As a priority strategy, diversification strategy is stable against a variety of changes/ interventions positively or negatively related to growth, continuity, competitiveness and profit of processed fisheries products of fish salted and boiled.

Judul: Sustainable management of capture fishery in Jakarta Waters, DKI Jakarta Province
Abstrak: Jakarta Waters is categorized as fully exploited water areas which its coastal areas accommodate multifunction services. Therefore, it needs precautionary approach to manage fisheries activity and its resource in the location. This is important to sustain the potential resource, provide prosperity to fishermen as well as coastal communities. The general objectives of this study are to arrange the sustainable fishery management in Jakarta Waters, while specific objectives of this study are to evaluate capture fishery management status; to determine optimum allocation of potential fishing gears and fisheries development areas based on potential fishing gears; to analyze the various components affecting to capture fishery activity based on suitable area and to analyze internal and external conditions in order to arrange the strategies for sustainable fishery management in Jakarta Waters. The methods used in this study were system approach, SWOT analysis, Linear Goal Programming (LGP) analysis, analysis of Location Quotients (LQ), Geographic Information System (GIS) analysis, and Analytical Hierarchy Process (AHP) method. The results revealed that the management of capture fishery in Jakarta Waters was categorized as "kurang baik" with the total scores of 2.529 and 2.747 for internal and external factors analysis, matrix IE pointed out that the position of fishery management at growth level which need strategy to do coordination horizontally with the other stakeholders. By using GIS analysis, it was identified that 52,89% of Jakarta Waters can be used for capture fishery, less than 25% can be used for fish farming (cage culture) and less than 15% can be used for seeweed culture. Meanwhile the potential fishing gears to be developed were pelagic danish seine, drift gillnet, boat lift net, set bottom long line, portable trap and muro ami which have the optimum allocation for each fishing gear; 7 units, 98 units, 23 units, 18 units, 8547 units, and 798 units. The potential fishing gears for pelagic danish seine could be developed in Penjaringan and North Seribu Island Districts; drift gillnet could be developed in Cilincing District; boat lift net could be developed in Penjaringan District; set bottom long line could be developed in Penjaringan District; portable trap could be developed in Cilincing and South Seribu Island Districts while muro ami could be developed in Penjaringan and South Seribu Island Districts. The study identified that there are several important strategies to support sustainable capture fishery management, from the first priority to the last are small-scale fishery standardization, integrated management to conserve the ecosystem function, quality product improvement, fishing days opreration management by implementing closed – open seasons, increasing independent fishermen capability, human resources empowerment, extention for fishermen and increasing capture fishery activities supervision. As the first priority, the standardization of small-scale fishery should be stable against changes in the dimension of biology and quite stable against changes in the ecological, economic, social and technological dimension.

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.
