Abstract

The coastal region of Jepara, Central Java, is increasingly vulnerable to environmental hazards due to rising sea levels, land subsidence, and climatic variability. Recent public concerns regarding the potential submergence of parts of Jepara and the possible reappearance of the ancient Muria Strait underscore the need for a scientific assessment of regional coastal stability. This study aims to evaluate the impacts of sea level rise on the vulnerability of Jepara’s coastal areas to tidal inundation. Using secondary data from 2013 to 2024, the analysis includes trends in mean sea level (MSL), sea surface temperature (SST), and documented land subsidence in nearby coastal cities. The results indicate an average annual MSL increase of 4.23%, with projections reaching up to 3.83 meters by 2050 if current trends persist. SST also shows a consistent upward trend, contributing to thermal expansion and sea level rise. Tidal flood mapping reveals that rice fields and coastal settlements are the most affected land uses, with 1,960.66 hectares of agricultural land and 207.48 hectares of residential area exposed to periodic inundation. The compounded effects of sea level rise, SST increase, and subsidence suggest an urgent need for mitigation planning and adaptive infrastructure to reduce future flood risks.

Abstract

Jepara Regency, located on the northern coast of Central Java, Indonesia, with a coastline of approximately 82.72 km, has experienced significant topographic changes driven by natural processes and anthropogenic activities. These changes, combined with increasing rainfall variability, have heightened flood risk in several parts of the region. This study aims to analyze topographic changes between 2014 and 2023 and to assess flood risk by integrating rainfall intensity and slope characteristics using a GIS-based multi-criteria spatial analysis approach. This research utilizes secondary spatial and climatological data. Rainfall data for the period 2020–2022 were obtained from the Meteorology, Climatology, and Geophysics Agency (BMKG) and classified according to rainfall intensity levels. Topographic and slope data were derived from the National Digital Elevation Model (DEMNAS) and the Indonesian Topographic Map (RBI). The analysis involved slope classification, scoring, weighting, and weighted overlay techniques using Geographic Information System (GIS) tools implemented in ArcMap software. The results indicate pronounced seasonal rainfall variability in Jepara Regency, with the lowest rainfall intensity occurring in July and the highest intensities recorded between December and January, ranging from 10.45 to 85.91 mm/day. Topographic analysis shows that areas with moderate slopes (8–15%) are vulnerable to extreme weather events and potential slope instability, while flat areas with slopes of 0–1% exhibit high susceptibility to flooding due to limited surface runoff capacity and land-use conditions. The total flood-prone area identified covers approximately 686.6 ha. Overall, the integration of rainfall and topographic parameters through GIS-based multi-criteria spatial analysis proves effective in identifying flood-risk zones and provides valuable input for spatial planning, disaster risk reduction, and coastal management in Jepara Regency.

Abstract

Perubahan morfologi pantai menjadi isu penting dalam pengelolaan pesisir karena memengaruhi ekosistem, infrastruktur, dan ketahanan wilayah, terutama di Indonesia yang memiliki garis pantai kedua terpanjang di dunia. Kajian ini meninjau perkembangan metode analisis perubahan morfologi pantai periode 2000-2025 serta mengidentifikasi kelebihan, keterbatasan, dan relevansinya di kawasan tropis, dengan fokus pada pesisir utara Jawa Timur. Metodologi mengikuti protokol PRISMA melalui identifikasi, penyaringan, penilaian kelayakan, dan seleksi akhir, menghasilkan 88 artikel dari Scopus dan pustaka nasional. Hasil menunjukkan metode DSAS/GIS dan citra satelit mendominasi studi jangka panjang, sedangkan UAV/LiDAR unggul untuk pemantauan lokal berpresisi tinggi. Model numerik efektif mensimulasikan skenario ekstrem, tetapi memerlukan data rinci yang masih terbatas di Indonesia. Dalam dekade terakhir, machine learning dan Google Earth Engine mulai diterapkan untuk analisis otomatis skala besar, meskipun terkendala minimnya data ground truth. Kajian ini menekankan perlunya integrasi multi-metode untuk pemahaman komprehensif dan pengembangan pendekatan hibrid bagi mitigasi abrasi, adaptasi iklim, dan perencanaan pesisir berkelanjutan.
