Judul: Potensi dan Pola Pemanfaatan Sumber Daya Perikanan secara Berkelanjutan di Perairan Bengkulu (Studi Kasus: Ikan Bleberan (Thryssa sp.), Tenggiri (Scomberomorus sp.) dan Kape Kape (Psenes sp.))
Abstrak: The potential of fishery resources in the waters of Bengkulu has been used by local people as a source of livelihood and has been used to support the of economy. But the management of coastal and marine resources that have been made have not successfully contributed to the prosperity for coastal and ocean communities in Bengkulu. Therefore, it is necessary to do an analysis of the sustainability of fishery resources in order to formulate a policy of sustainable utilization of fishery resources. The purpose of this study was to analyze the pattern of utilization of fishery resources, determine the potential of fishery resources, determine the status of fishing communities, determine stock status of fishery resources and formulate strategies of resource use sustainable fishing in the waters of Bengkulu. This research was conducted at the beginning of October to the end of November 2014. The location of the research was in the province of Bengkulu. The measurement of the fish’s lenght was done in two (2) locations namely: Fish Landing Ports, Baai Island and Fish Landing Sites. This study used primary and secondary data related to the continual attribute dimensions, namely: Dimension of ecology (8 attributes), economy (8 attributes), social (6 attributes), technology (8 attributes) and institutional (5 attributes). The primary data were obtained from direct observation and from interviews with 200 respondents (4 chairmen from marine and fisheries department, 4 chairmen from Fish Landing Ports/ Fish Landing Site, 4 chairmen of co-operative, a chairman of HNSI and 177 persons representing fishermen throughout the province of Bengkulu). The purposive sampling method was used in this research. The lenght measurement of Kape Kape Fish (1.322fish), Bleberan Fish (699 fish) and Tengiri Fish (492 fish) was also performed. All of these fish is dominant fish caught by fishermen. Kape kape and tengiri were the target fish which had a high economic value and Bleberan fish was not the target fish, moreover, these fish had a low economic value. The continual analysis of fishery resources in the waters of Bengkulu was done by using the Multi Dimensional Scaling (MDS) technique through RAPFISH (Rapid assessment Technique for Fisheries) approach. In determining the priority of fishery resources management policy strategies, the reseacher used kobe plot analysis (Zhang et al 2009) in which the priority was done based on the value of the indicator and risk. After that, the determination of Management Plan Periode was carried out. The indicators and the value of the indicators used in kobe plot analysis were the same as indicators along with their value at RAPFISH. Fishing area for fishermen in the waters of Bengkulu stretches along the coastline to the sea, with a distance of fishing base Manna (pasar bawah), pasar Bengkulu, pasar bantal, pasar Ipuh and pulau Baai reached by consuming ranged from 0.5 hours up to 9 hours. Fishing gear which make a major contribution to the total production of fisheries in the waters of Bengkulu, namely: beach seines, lift nets other, drift gill nets, other fishing, fixed gill nets and nets three layers. The size of the fish caught by

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.
