Judul: Strategy for Managing of Cilincing Fisheries Port North Jakarta
Abstrak: The Cakung Drain river ends at the water system of Cilincing Fisheries Port. As the river is highly polluted by domestics and industrial waste, it contributes significantly to the pollution of Cilincing fisheries port. The aim of this research is to estimate the pollution load and the assimilation capacity of the Cilincing Fisheries Port and to formulate a strategy for management of Cilincing Fisheries Port. Sample analysis and fied survey dery were conducted September 2005 uatil Mei 2006. SWOT analysis was used for formulating an effective strategy for management of the Cilincing Fisheries. Results from a research showed that the estimed pollution load from the river are as follow (each in ton/month) are BOD5 365,85, NO3 10,66, NH3 17,27, PO4 10,82, Pb 20,11 and COD 10.235. The assimilation capacities of each parameter observed for 500 m and 1.000 m from the coastal are as follow (each in ton/month) BOD5 (1.997,72 and 3.11,52), NO3 (-0.57 and -6,92), NH3 (22,65 and 19,94), PO4 (15,43 and 13,59), Pb (9,73 and 8,86), and COD (-22.150 and 434,31). Based on the result of SWOT analysis, the main strategies for management Cilincing Fisheries port, are namely : (1) To increase stakeholder attention relating to the management and utilization of marine resources that is supported by qualified human resources in order to get good sanitary; and (2) Rearrange of fisheries area and improve fisheries society by developing a comprehensive and integrated of Cakung Drain create high economy value.

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: Konstruksi aritmetika kurva eliptik F(2m) supersingular dan non-supersingular untuk skema kunci publik ElGamal
Abstrak: Algoritme ElGamal adalah salah satu algoritme kunci publik dengan aritmetik modular p yang mempunyai struktur grip siklik Z(p). Tingkat keanaman algoritme ini terletak pada pemecahan masalah logaritme diskret dari Z(p). Akan tetapi, tingkat keamanan tadi tahun ke tahun semakin menurun yang disebabkan kemampuan pemecahan algoritme diskret semakin meningkat. Untuk memenuhi tingkat keamanan yang memadai dibutuhkan p yang cukup besar yang menyebabkan proses enkripsi dan dekripsi menjadi lambat.
