Judul: Fishing Capacity of Line Fishing Fleet at  Palabuhanratu Archipelago Fishing Port, Sukabumi, West Java
Abstrak: Kapasitas penangkapan (fishing capacity, FC) adalah kemampuan armada kapal perikanan untuk menangkap ikan secara maksimum dalam periode satu tahun pada kondisi normal operasi penangkapan ikan. Pengendalian FC belum diterapkan dalam pengelolaan perikanan di Indonesia karena belum ada standar perhitungan FC yang sesuai dengan keragaman kapal perikanan di Indonesia. PPN Palabuhanratu (PPNP) yang merupakan pelabuhan perikanan penting di pesisir selatan Jawa, dimana dominasi armada perikanan alat tangkap pancing menjadikan alat tangkap ini sebagai fokus penelitian. Tujuan penelitian yaitu menghitung FC armada perikanan pancing di PPNP. Data dikumpulkan dengan cara observasi, pengukuran, dan wawancara langsung di lapang. Hasil penelitian menunjukkan bahwa nelayan kapal kecil di PPNP menggunakan wadah penyimpanan styrofoam atau fiber box dengan es sebagai media penyimpanan sedangkan kapal besar menggunakan palka sistem refrigerated sea water. Nilai FC armada perikanan pancing di PPNP sebesar 18.766 ton/tahun.

Judul: Produktivitas Armada Penangkapan Pancing di Sekitar Rumpon, Palabuhanratu Jawa Barat
Abstrak: Fishing line with rumpon is the most widely used by fishermen in Palabuhanratu water’s, Sukabumi. This research aims to estimated productivity of fishing line with rumpon in different season, to figure out fishing ground, and total catch of training vessel PSP 01 operated in PPN Palabuhanratu water’s. Surveys method was used in the research and collected the primer and secondary data. The analysis of catch per unit effort (CPUE) was estimated to determine the position of fishing ground of tuna. Result of the research showed that off season during December to February, normal season in March until May, October until November, and peak season from June to September. The productivity of fishing line was increased from off season to peak season. The average CPUE from 2007 to 2011 comprises of 419,88 kg/trip (off season), 582,07 kg/trip (normal season I), 734,47 kg/trip (normal season II), and 818,90 kg/trip (peak season) respectively. The fishing ground of training vessel PSP 01 is located at the southern water’s of Palabuhanratu (07035’188 – 07059’874 South dan 106018’096 – 106025’112 East).

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.
