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

Determining the location and dimensions of coastal protection structures, especially breakwaters, must take into account oceanographic data so that the structure can function effectively to protect the coast from damage caused by waves and currents. The method employed in this study is a quantitative approach, utilizing secondary data from the Meteorology, Climatology, and Geophysics Agency (BMKG), National Bathymetry data (BATNAS), and primary data collected directly through field observations, including sedimentation and tidal data. Based on the research conducted, the sedimentation rate for point 1 was 402.405 cm3/year. Point 2 was 503.006 cm3/year. Point 3 was 955.713 cm3/year. For tidal data obtained, the Higher High Water Level (HHWL) is 1.78 m, the Mean High Water Level (MHWL) is 1.2053 m, the Mean Sea Level (MSL) is 0.9203 m, the Mean Low Water Level (MLWL) is 0.6353 m, and the Lower Low Water Level LLWL) is 0.20 m. The dominant wind for 10 years blew from the north, with a maximum wind speed of 11 knots and an effective fetch length of 398.21 km. From the wave forecast, the breaking wave height (Hb) is 76.44 meters, the breaking wave depth (db) is 3.822 meters, the maximum wave height is 2 meters, and the period is 7 seconds.
