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: Fishermen work safety at fishing operation on payang in Palabuhanratu, West Java
Abstrak: The main cause of marine accidents resulting in loss of human lives is purely human error. Specifically on the capture fisheries, as many as 80 percent of marine accidents are caused by factors of human negligence (FAO, 2009). The purpose of this study is to inventory and describe all hazards and possible consequences in every aspect and stage, inventory and identify those aspects related to the management of safety of fishermen, both institutionally, existing regulations, human resources, working conditions and safety design models fishermen work at the sites. Scope of the study was limited to payang fishing activities in fishing operations in Palabuhanratu. The research was conducted in October 2011 - August 2012, in district Palabuhanratu West Java, especially in PPN Palabuhanratu. This research activity was carried out by conducting literature studies and interviews with the aim of collecting primary data in the form of direct observation and interviews/questionnaires to all the components, either directly or indirectly involved. Collection of secondary data fishery, related regulations, journals, and other related literature. Policy and institutional analysis be descriptive. The next method is the Formal Safety Assessment (FSA), the human element can be incorporated into the FSA process using human reliability analysis (HRA). HRA in this study quantitatively. To complete the picture details the development of systems analysis models to understand and make decisions related to SMK3. Activity that has a chance of failure risk was greatest in gear operating activities during setting. Consequences of accidents greatest opportunity in hauling activity. Risk control is done with the selection of a competent crew, plan fishing/sailing, designing safe work procedures, use of equipment as needed, using personal protective equipment and conditioning healthy working environment, as well as coordination among crew always do. Need to restructure relating to the management of fishing safety associated with existing policies and institutions, so that the mutually synergistic implementation. Analysis of the safety management system of the fishermen showed no systemic features and characteristics of the organization who have learning disabilities. (A) Each stakeholder tends to stand in their own point of view or interest. (B) Completion of the problems in safety management fishermen tend gradually, not structured and are regional and do not change the mindset. (C) In the safety management practices on certain aspects (control) often occurs transitional resources for the benefit of others. This transfer shows that the issue of safety management is not a priority fishermen and not something that should be addressed immediately. (D) Aimed of fishing safety management is not up to the level of implementation.

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.
