Judul: Peralatan Keselamatan Kerja pada Perahu Slerek di PPN Pengambengan, Kabupaten Jembrana, Bali
Abstrak: Fishing is one of the most dangerous activities in the world. About 80% of ship accidents occur due to human error. The availability and proper use of safety equipment can minimize the risk. This study aims to identify the suitability of safety equipment used on Slerek boat in PPN Pengambengan, Bali accordance with international and national standards, and describes the role of relevant institutions in order to increase the fishermen safety. Surveys and direct observation methods were used in this study. Aspects of the study were the types of safety equipment, numbers of safety equipment, and the suitability of equipment which must be taken. The lack of equipment and awareness about safety, and do not comply with the national standards for boat less than 24 meters length will directly affect the fishermen safety. The lack of regulations on small boat safety showed that the fishermen safety in fishing activities in Indonesia have not been considered and there is no clear policy from local and central government

Judul: Penilaian Kecukupan Alat Keselamatan Kerja Kapal Perikanan Menurut Aturan Standar Kapal Non-Konvensi
Abstrak: Armada perikanan di Indonesia dinilai masih belum memenuhi persyaratan dalam kelengkapan peralatan keselamatan. Padahal, tidak lengkapnya peralatan keselamatan merupakan salah satu aspek yang dapat menyebabkan kecelakaan fatal terhadap awak kapal, khususnya awak kapal perikanan. Penelitian ini bertujuan untuk mendeskripsikan jenis dan fungsi peralatan keselamatan kapal pada aturan standar kapal non konvensi Indonesia, serta membandingkan kondisi sebenarnya keberadaan peralatan dan perlengkapan keselamatan sesuai dengan aturan standar kapal non konvensi Indonesia pada kapal kelas 3B. Metode yang digunakan dalam penelitian ini adalah studi pustaka dan observasi secara langsung pada 30 kapal purse seine kelas 3B yang berlayar di WPP 572 dengan tonase di atas 100 GT. Hasil penelitian menunjukkan bahwa terdapat lima belas ketentuan mengenai peralatan keselamatan. Tingkat pemenuhan ketentuan peralatan keselamatan standar kapal non konvensi masih rendah. Hanya tiga dari lima belas ketentuan yang berhasil dipenuhi oleh kapal purse seine di PPS Nizam Zachman, yakni ketentuan sampan sejumlah 25%, ketentuan pelampung penolong sejumlah 75%, dan ketentuan baju penolong sejumlah 50%., Fisheries fleets in Indonesia are considered to still do not meet the requirements for the completeness of safety equipment. In fact, incomplete safety equipment is one aspect that can cause fatal accidents to ship crews, especially fishing boat crews. This study aims to describe the types and functions of ship safety equipment in the standard rules of Indonesian non-conventional ships, as well as to find out the actual condition of the existence of safety equipments in accordance with the standard rules of Indonesian non-conventional vessels on class 3B vessels. The method used in this research is literature study and direct observation on class 3B fishing vessels sailing in WPP 572 with tonnage above 100 GT. The results of this study indicate that there are fifteen provisions regarding safety equipment. The level of compliance with non-conventional standard ship safety equipment regulations is still low. Only three of the fifteen conditions were successfully fulfilled by purse seine vessels at PPS Nizam Zachman, namely the provision for dinghy (25%), the provision of life buoys (75%), and the provision of life jackets (50%).

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.
