Judul: Fishery development policy in boundary area of Kepulauan Talaud Regency
Abstrak: The objective of this research is to develop policy for the management of fisheries resources in border area of Talaud Regency. To achieve such an objective, the study was carried out to analyze 1) The role of marine fisheries sector within the Talaud Regency, 2) The optimal utilization of marine fisheries resources in Talaud. The results of the study showed that 1) The fishing sector plays a greater role in to economic of Talaud Regency, 2) Optimal fishing effort under MSY condition is around estimated at 9.610 trip with production level of 5.4448,75 ton. Economic rent under MSY condition is approximately Rp. 34.426,94 billion. If the fishery is managed under maximum economic yield (MEY), it was found that effort level should be around 8.853 trip with production level at 5.414,93 ton. Economic rent under MEY condition is approximately Rp. 34.680,52 billion. The study also found some economic performances of fishing unit operating in Talaud. It shows that “pancing tonda” (troll line) receives highest surplus, then it followed by “pukat cincin” (purse seine) and the last is “jaring insang hanyut” (drift gillnet). Based on simulation, it was found that domestic fleet should be encouraged to increase production so as to offset illegal fishing from Phillipine vessels. The number of domestic vessels in Talaud will eventually increase up to 700 fleets as a respond of illegal fishing by foreign fleet. It is also found that illegal fishing will lead to economic loss between Rp 1 billion to Rp 2 billion per year. While if no illegal fishing economic potential of fishery in Talaud could reach to Rp 7 billion to Rp 10 billion, if illegal fishing is still rampant, within 20 years economic loss will be much higher which eventually will affect the economic of Talaud regency as a whole. Results of Analytical Hierarchy Process (AHP) indicates that to develop fisheries sector in Talaud, provision of regional budged devoted for fisheries sector is number one priority followed by regional cooperation and local empowerment. Other factors such as forming market for fisheries in the Talaud area and increasing number of fishing units come after those three priorities. Overall, result of AHP strongly indicates serious political will from local government to develop fisheries in Talaud. This study also reveals that based on Linear Goal Programming (LGP) it needs a total of 1536 fishing units, one unit of coastal fishing port (PPP), one unit fisheries landing base (PPI) with requires area of 441 m2. LGP also states that it needs three unit of fish processing and additional labor force of 6524 fishers and another 1500 for supporting activities.

Judul: Development of Pelagic Fishing Unit in South Bangka Regency
Abstrak: The fishery condition in South Bangka Regency still has some limitation, among others are the capacity and unattainability of fishing ships, low fishermen knowledge in the modern fishing technology, and capability of local fishermen to fish in a long period is limited, so that they tend to use fishing gear that only sufficient to use a long the shore.Another fact proved that in general fish resource utilization is still carried out using stationary fishing net i.e. bottom gillnet and hand line so that the fishery potency especially pelagic fish is not optimized. The objectives of the research are first to carried out a selection on fishing unit based on, biology, economy, and social aspects, secondly to look for optimum pelagic fishing allocation in the South Bangka Regency and third to determine the strategy for the development of pelagic fishery in South Bangka Regency. The methodology being used were survey and observation on the pelagic fishery condition at the research location. Data was obtained through direct interview with the pelagic fishery fishermen based on the fishings gears they used. Interviews were also carried out with the fishery stakeholders and collectors i.e. PPI Sadai and local fishery ageny officers. The dominant fishing gears used by the fishermen were line fishing, stationary life net, and gillnet. A new fishing gear that was the millenium net that was introduced by Andon fishermen from Indramayu Regency. Based on the financial criteria analysis the stationary life net has the bighest R/C value compared to other fishing gears. Therefore, it is expected that stationary life net will develop rapidly. However, looking into the investment criteria the stationary life net has low B/C value compared to boat life net. In this regard, both fishing gears could be considered to be developed in South Bangka Regency. The analysis of the four (4) aspects i.e. biology, technical, economy, social presented that in sequence the unit that has good prospect to be developed are millennium net boatlife net, line fishing, stationary life net, and gillnet. To have optimum utilization of existing pelagic fish resource a strategy was prepared based on the resource characteristic and local community. The first strategy is fish resource utilization using environment friendly fishing gear and second improved productivity and value added of pelagic fish. The formulated strategy could be taken as a reference by the South Bangka Regency Local Government to decide the policy and program in the development of the pelagic fish in this area using the fishing principle that are accountable and environment friendly, beside that the program should be able to overcome the problem arouse in the community to reach higher fishermen productivity and welfare.

Judul: Grup dan Homomorfisma Grup pada Rubik Revenge
Abstrak: Rubik cube is a kind of puzzle game. A player must arrange rubik sides, which have been disordered, back to the position where every side has the same colour. This paper does not focus on the settlement solution, but instead on proving the existence of a group homomorphism between rubik movement group and S96 symmetric permutation group in rubik revenge. Firstly, it has been proved that rubik movement set is a group. Then, it also has been proved that the M set, which contains numeric labels of 1 until 96 in cubinos sides, is S96 symmetric permutation group.
