Abstract

Fish Safety Foundation (FSF) mengidentifikasi beberapa faktor penyebab kematian nelayan. Faktor-faktor tersebut mencakup kemiskinan, konflik geopolitik, penangkapan ikan berlebihan (overfishing), penangkapan ikan yang ilegal, tidak dilaporkan, dan tidak diatur (illegal, unreported and unregulated/IUU fishing), serta perubahan iklim. Penangkapan ikan yang ilegal, tidak dilaporkan, dan tidak diatur adalah pendorong yang signifikan, terutama karena permintaan protein ikan meningkat secara global. Para operator ilegal industri perikanan mengambil jalan pintas dan mengabaikan aturan keselamatan sambil berkontribusi pada eksploitasi tangkapan yang sangat menguntungkan secara berlebihan. Nelayan tradisional skala kecil didorong untuk melanggar aturan atau mengambil bagian dalam kegiatan berbahaya yang tidak diatur karena semakin sulit untuk menemukan ikan. Kondisi ini diperparah dengan perubahan iklim dan perubahan distribusi stok ikan. Sebagai masyarakat yang hidup berdampingan dengan nelayan, penyuluhan tentang keselamatan dan kesehatan nelayan dapat dilakukan oleh siapapun termaksud oleh akademisi. Oleh karena itu, pengabdian ini ditunjukan pada nelayan skala kecil untuk lebih sadar terhadap pentingnya Keselamatan dan Kesehatan kerja dengan dilakukan penyuluhan kepada 30 nelayan di Surabaya Timur.

Abstract

Lamong Bay is a strategic area, and in 2010 a port was built to improve competitiveness. This study analyzed shoreline changes in the western part of Lamong Bay in 2004, 2009, 2014, 2019, and 2024 using Landsat 7 ETM+ and Landsat 8/9 OLI/TIRS imagery. Data extraction used the Normalized Difference Water Index (NDWI) method in ArcGIS, while shoreline change analysis used the Digital Shoreline Analysis System (DSAS) with End Point Rate (EPR), Net Shoreline Movement (NSM), and Shoreline Change Envelope (SCE). The results show the highest accretion occurred in Romokalisari Village from 2004 to 2009 at 13.80 meters/year, and the highest abrasion occurred in the same village from 2019 to 2024 at -34.21 meters/year. Based on NSM, the highest accretion occurred in Romokalisari from 2004 to 2009 at 67.42 meters, and the highest abrasion occurred from 2019 to 2024 at -163.38 meters. Based on SCE, the highest change occurred in Romokalisari at 331.93 meters from 2019 to 2024, and the lowest change occurred in Osowilangun Village at 0.01 meters in the same period. Overall, accretion dominates the study area, but extreme abrasion in Romokalisari from 2019 to 2024 is influenced by reclamation. This study is expected to support sustainable coastal management and shoreline change mitigation.

Abstract

The discipline of Integrated Coastal Zone Management (ICZM) is still growing, especially in Indonesia, but its implementation is still relatively young. This study focuses on beach tourism. Ecotourism development and management is one of the efforts to utilize local resources that must be optimal. Delegan Gresik Tourism Beach, East Java, is a management research area for ecotourism development. This research aims to determine the potential of existing resources in Delegan Beach attractions and make scenarios for development plan efforts. This is done through Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis and interviews to determine resource potential, development alternatives and priorities, both through analysis of internal and external factors. The results of this study show that forms of stakeholder participation influence the determinants of the development of natural tourism areas on Delegan Beach. The resulting development directions include the use of various resources, the development of facilities as community business opportunities, the empowerment of community skills, the Improvement of regional socialization, and efforts to preserve the environment.
