The coastal area of Cirebon located on the North Coast of Java (Pantura) is a densely populated region that is being developed for industrial and fisheries purposes. One of the problems faced in this coastal area is tidal flooding, commonly known as "banjir rob." As a result, this area is included in the Coastal Protection Project for five urban areas along the North Coast of Java (Pantura) in the National Medium-Term Development Plan (RPJMN) 2020-2024. This study aims to provide a deeper understanding of the occurrence and risks of inundation in Cirebon using the Geographic Information System (GIS) method. It simulates the potentially flooded areas over a 30-year period from 2025 to 2045, considering various scenarios based on projections of sea-level rise, La Niña events, storm surges, and inland flooding. In scenario 4, which accounts for the highest tidal level, inland flooding, La Niña events, and storm surges, the highest projected sea-level rise is 121.16 cm, resulting in an inundated area covering 13.701 ha (approximately 12,29% of the total area of Cirebon Regency and City). According to this scenario, 15 districts are impacted, with Losari, Kapetakan, Pangenan, and Suranenggala districts being the most severely affected, with inundation covering more than 25% of their respective areas. Additionally, in each scenario, more than 50% of the total area of fishponds in Cirebon Regency and City is flooded, and around 263 – 463 km of pathways are submerged.
