Judul: Kebijakan Pengembangan Ekonomi Perikanan Tuna Longline Berperspektif Mitigasi Bencana Di Padang, Sumatera Barat
Abstrak: This research aimed to determine 1) fisheries sector macro economic conditions, 2) the potential for sustainability and management of fisheries resources, 3) the potential and priorities for mitigation of disasters, 4) the fisheries development and the feasibility investment of disaster mitigation perspective, 5) institutions in fisheries development of disaster mitigation perspective and 6) formulate policy direction of tuna fisheries economy development based on disaster mitigation perspective. The analysis methods was conducted by Shift Share, Location Quotient, Minimum Requirement Approach, Bioeconomic Model, Exponential Comparison method (MPE), Investment feasibility analysis, stakeholder analysis, descriptive analysis and AHP techniques. The result showed that fisheries provide high contribution in macro economic analysis as the leading sectors of regional economic development. The analysis of bioeconomy, especially Tuna was bellow the optimal level, with the optimal management based on MEY management regimes showed that effort can be increase by 133 trip or equal as 33 tuna longliners and a production of 418.53 tons. The highest potential disaster on fisheries was earthquakes, tsunamis, strong winds, and waves. Strategies for mitigation priorities were (1) provision of GPS, APS, disaster information applications for fisherman, (2) provision of early warning and integrated information systems, also (3) establishment of building fishing ports and other infrastructure disaster mitigation perspective. Investment feasibility analysis showed longliner tuna productivity remains high as well as the addition of mitigation facilities, so the development of the business was feasible. Stakeholders involved in this policy were KKP, DKP and local government. This research concluded that appropriate policy strategies could be implemented in Padang city was optimization the production of sustainable fisheries resources through the provision of facilities for fisheries and mitigation perspective, also increase participation and synergy stakeholder to prosperity.

Judul: Kebijakan Pengembangan Ekonomi Perikanan Tangkap Berkelanjutan di Provinsi DKI Jakarta
Abstrak: Capture fisheries subsector in DKI Jakarta Province has been facing serious problems on various dimensions. Those problems threat its sustainability in the future. Fisheries sustainability is determined by several interacting dimensions such ecology, economic, social. technology and institution. The purpose of this research is to 1) estimate optimum alocation of capture fisheries in DKI Jakarta Province, 2) determine the degradation and depreciation level of capture fisheries in DKI Jakarta, 3) determine the sustainability status of capture fisheries in DKI Jakarta according five sustainability dimensions (ecology, economy, social, technology, and institution), 4) determine dynamic optimation management of capture fisheries in DKI Jakarta Province, and 5) formulate policy direction of economic development of sustainable capture fisheries in DKI Jakarta Province. The fisheries resources on this research seperated as pelagic and demersal. The research used bioeconomic analysis, degradation and depreciation analysis, sustainable analysis with Rapfish techniques and dynamic analysis. Result of the bioeconomic analysis showed that the harvest and effort of pelagic and demersal resources were above than optimal level therefore those resources have been over exploited. Degradation and depreciation analysis showed that pelagis resouce have been degraded dan depreciated meanwhile demersal resource have been not degraded dan depreciated. Sustainable analysis with Rapfish techniques using multi dimension scalling (MDS) and modification of AHP showed that the sustainability index of pelagic was 39,63. Based on categorized, it means was in less sustainable with economic dimension as the most priority dimension that influently to sustainability of pelagis resources. Mean while, the sustainability index of demersal resources was 37,15. It means the resource was less sustainable with ecology dimension as the most priority dimension. The dynamic model of this research was composed of three sub models, such as ecology, economic and social. Those sub models were used to predict of sustainability indicators on each dimension. The indicator of ecology, economic and social model were natural stock of resources, profit and profit to UMR. Result of dynamic analysis showed that limiting number of fishing effort can kept the natural stock of fish on sustainable stock. Based on result of all analysis, one of the best policy to improve sustainability of capture fisheries in DKI Jakarta is synergetic policy which consider ecology, economic, and social indicators.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
