Judul: Safety Management of Fishing Boats Less Than 12 Meters at the Jayanti Fishing Port, Cianjur, West Java
Abstrak: Nelayan merupakan salah satu pekerjaan yang memiliki resiko dan bahaya yang tinggi. Data dari Komite Nasional Keselamatan Transportasi (KNKT) menunjukkan jumlah kecelakaan kapal di Indonesia dari tahun 2013 hingga 2021 sebanyak 124, yaitu tenggelam, tabrakan, terbalik, terbakar, dan kandas. Penelitian ini dilakukan untuk menganalisis manajemen keselamatan berdasarkan Siklus Danielsson dan merumuskan strategi mitigasi untuk mengurangi kecelakaan kerja nelayan di Pelabuhan Perikanan Jayanti. Penelitian menggunakan metode purposive sampling penentuan responden yaitu nelayan, pemilik kapal, dan petugas pelabuhan perikanan. Hasil penelitian menunjukkan bahwa Pelabuhan Perikanan Jayanti tidak memiliki semua komponen Siklus Danielsson, seperti rehabilitasi, mitigasi, dan kesiapsiagaan. Strategi peningkatan keselamatan nelayan adalah dengan meningkatkan pengetahuan tentang Kesehatan dan Keselamatan Kerja (K3), memberikan pelatihan nelayan mengenai alat keselamatan kerja dan pedoman penanggulangan kecelakaan kerja nelayan., Fishermen are one of the jobs that have high risk and danger. Data from The National Transportation Safety Committee shows the number of ship accidents in Indonesia from 2013 to 2021 was 124, including sinking, collision, overturning, burning, and running aground. This paper is conducted to analyze the safety management based on the Danielsson Cycle and formulate mitigation strategies to reduce fishermen's work accidents at Jayanti Fishing Port. The research uses a purposive sampling method for fishermen, boat owners, and fishing port officers. The result indicated that Jayanti Fishing Port doesn't have all Danielsson Cycle components, such as rehabilitation, mitigation, and preparedness. The strategy for increasing fisherman safety is increasing knowledge about Occupational Health and Safety (OHS), providing fisherman's work safety tools and guidelines for mitigating fishermen's work accidents.

Judul: Potential Risks of Fisherman’s of Handline Ship Based in Cilacap Ocean Fishing Port
Abstrak: Banyaknya peluang terjadinya kecelakaan pada kapal handline khususnya di kolam pelabuhan maka perlu ditentukan tingkatan bahaya. Tingkatan bahaya tersebut dapat mempermudah menentukan skala prioritas antisipasi yang harus dilakukan. Penelitian ini bertujuan menentukan potensi risiko dan jenis kecelakaan kerja serta memastikan kelengkapan alat keselamatan kerja pada kapal handline di PPS Cilacap. Pengambilan sampel menggunakan metode purposive sampling, serta pengolahan data menggunakan tabulasi nilai dan analisis deskriptif. Hasil penelitian menunjukkan pengelompokan matriks risiko pada aktivitas kapal menuju bongkar muat kedalam lima kategori. Kategori sangat tinggi terdiri dari 10 risiko, kategori tinggi 5 risiko, kategori sedang 2 risiko, kategori rendah 3 risiko, dan kategori sangat rendah 0 risiko. Upaya untuk mengurangi terjadinya risiko kecelakaan kapal ialah melengkapi kebutuhan dan memakai Alat Pelindung Diri (APD). Sarana dan prasarana yang telah diberikan oleh pihak dinas PPS Cilacap berupa life jacket dan pelampung bulat di setiap kapal. Ketersediaan APD tidak dipergunakan dengan baik sehingga perlu adanya penyuluhan dan pengawasan mengenai kedisiplinan nelayan terhadap penggunaan APD yang menjadi upaya mengurangi risiko kecelakaan kapal yang terjadi., So many chances accidents of the handline ship especially the fishing port pool need to be determined a danger level. There is a level of danger can make it easier to determine priority scale of anticipation that must be done. The purpose of this research to determine potensial risk and type of work accident as well as evaluate completeness safety tools on the handline ship in PPS Cilacap. Data collection was used purposive sampling method. Data processing was used tabulation of values and descriptive analysis. The result of the research showed the grouped risk matrix into five groups, that is low category, medium, and high. The low category have two risks, the extreme category have 10 risks, the high category have 5 risks, the medium category have 2 risks, the low category have 3 risks, and very low category 0 risks. Effort to reduce the chances of accidents on the ship is collect and to wear safety tools (APD). Facilities and infrastructure that has been given by PPS Cilacap is life jacket and float in every ships. Availability APD not used properly so there is a need for counseling and supervisi about the discipline of fishermen to used safety tools which is an effort to reduce the risk of the ship accidents.

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.
