Abstract

Teluk Lamong merupakan kawasan starategis. Pada tahun 2010 pada kawasan tersebut mulai dibangun sebuah pelabuhan untuk meningkatkan daya saing pelabuhan. Pada penelitian ini dilakukan analisis perubahan garis pantai pada area barat perairan Teluk Lamong. Analisis dilakukan pada tahun 2004, 2009, 2014, 2019, dan 2024 dengan menggunakan data citra
Landsat 7 ETM+ dan Landsat 8/9 OLI/TIRS. Diekstraksi dengan metode Normalized Difference Water Index (NDWI) pada software Arc-GIS. Untuk analisis perubahannya menggunakan software Digital Shoreline Analysis System (DSAS) dengan metode End Point Rate (EPR), Net Shoreline Movement (NSM), dan Shoreline Change Envelope (SCE). Didapatkan hasil perubahan setiap lima tahun dengan metode EPR akresi tertinggi terjadi di desa Romokalisari tahun 2004 – 2009 sebesar 13,80 meter/tahun, dan abrasi tertinggi terjadi
di desa Romokalisari tahun 2019 – 2024 sebesar -34,21 meter/tahun. Dengan metode NSM akresi tertinggi terjadi di desa Romokalisari tahun 2004-2009 sebesar 67,42 meter, dan abrasi tertinggi terjadi di tahun 2019-2024 sebesar -163,38 meter. Dengan metode SCE perubahan terjauh tertinggi terjadi di desa Romokalisari sebesar 331,93 tahun 2019-2024, dan parubahan terjauh terendah terjadi di desa Osowilangun sebesar 0,01 tahun 2019-2024. Berdasarkan hasil analisis seluruh area penelitian dominan terjadi akresi. Namun pada tahun 2019 hingga 2024 terjadi abrasi ekstrem pada desa Romokalisari yang disebabkan oleh adanya reklamasi. Penelitian ini diharapkan dapat menjadi dasar bagi pengelolaan pesisir yang berkelanjutan serta mitigasi dampak perubahan garis pantai.

Lamong Bay is a strategic area. In 2010, a port was built in the area to increase port competitiveness. This study analyzed coastal line changes in the western area of Lamong Bay. The analysis was conducted in 2004, 2009, 2014, 2019, and 2024 using Landsat 7 ETM+ and Landsat 8/9 OLI/TIRS imagery data. The data was extracted using the Normalized Difference Water Index (NDWI) method in ArcGIS software. For the analysis of changes, the Digital Shoreline Analysis System (DSAS) software was used with the End Point Rate (EPR), Net Shoreline Movement (NSM), and Shoreline Change Envelope (SCE) methods. The results showed that the highest accretion occurred in Romokalisari Village from 2004 to 2009 at 13.80 meters/year, and the highest abrasion occurred in Romokalisari Village from 2019 to 2024 at -34.21 meters/year. Using the NSM method, the highest accretion occurred in Romokalisari Village from 2004 to 2009 at 67.42 meters, and the highest abrasion occurred from 2019 to 2024 at -163.38 meters. Using the SCE method, the highest change occurred in Romokalisari village at 331.93 meters between 2019 and 2024, and the lowest change occurred in Osowilangun village at 0.01 meters between 2019 and 2024. Based on the analysis results, accretion is dominant across the entire study area. However, from 2019 to 2024, extreme erosion occurred in Romokalisari Village due to land reclamation activities. This study is expected to serve as a foundation for sustainable coastal management and mitigation of the impacts of shoreline changes.
