Judul: Peranan sektor perikanan dalam pengembangan wilayah Kabupaten Belitung
Abstrak: Fisheries sector is expected to be a strategic sector for regional development in Regency of Belitung in the future, based on its natural resources. The purposes of this study are: (1) identifying the existing and potential of fisheries sector, (2) identifying the role of the fisheries sector in development, (3) identifying the fisheries sector linkages with other sectors in regional development system, (4) exploring the perceptions of stakeholders regarding fisheries development priorities, and (5) formulating the guidelines of fisheries sector development. This research was conducted in the Regency of Belitung, Province of Bangka Belitung Islands, using primary and secondary data. The analyses used are descriptive analysis, Input-Output (IO), and Hierarcy Analytical Process (AHP). The results showed that fisheries production reaches 41,947.10 tons/year and still be able to be increased up to 85,252.90 tons/year. Fisheries sector contributed the highest in gross regional domestic product (GDP) up to 18.07%. However, it has a low linkages with other sectors. Main activities in fisheries development are fishing, aquaculture and processing. Fisheries development policies directed to increase the amount of production, and enhance the role and linkages of the fisheries sector with other sectors.

Judul: Studi peran subsektor perikanan dalam pengembangan wilayah di Kota Sibolga
Abstrak: Fisheries subsector is expected to be a strategic sector for future regional development in Sibolga, because this sector based on local resources that can be renewable. The purposes of this study are to: (1) to identify the fisheries subsector development in Sibolga, (2) to analyze the backward and forward linkages of the fisheries subsector economy in Sibolga, (3) to explore the perceptions of stakeholders about fisheries subsector development in Sibolga and (4) to formulate the direction of fisheries subsector development priorities in Sibolga. The data analysis used are descriptive analysis, Hierarcy Analytical Process (AHP), and Input-Output (I-O). The results showed that the fisheries subsector contributes the highest gross regional domestic product up to 22.86% and contributes to the total output up to 17.70%. Fisheries still have a potential to explore 123,63 thousand tons in WPP-572 zones, in addition to the exploitation outside the exclusive economic zone. The aquaculture activities (KJA) still have space 1,276.97 Ha to be used, located in the district of North Sibolga and Sibolga City. Fishieries subsector in total still has small backward and forward linkage. The low linkages fisheries subsector provide a low impact on increasing the output of other sectors directly and indirect linkages to other sectors. The perception of all stakeholders says human resources from fishing activities is a top priority in developing the fisheries subsector, but from analysis human resource aquaculture should be a priority development in fisheries subsector in Sibolga.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
