%X Flooding is one of the major hydrometeorological disasters that frequently affects Jakarta, particularly along the Ciliwung River Basin (DAS). This study aims to analyze the parameters that influence flood vulnerability in the Ciliwung River Basin, East Jakarta, using a spatial approach based on Geographic Information Systems (GIS). The analyzed parameters include rainfall, elevation, slope, land cover, and drainage density. Data were obtained from InaGeospatial and the Ciliwung-Cisadane River Basin Agency (BBWS), and were analyzed using spatial mean calculations and scoring through overlay techniques in ArcMap 10.8. The results indicate that land cover has the greatest influence on flood vulnerability, with a weight of 26%, followed by slope (22%), rainfall (18%), drainage density (18%), and elevation (16%). Mapping results show that approximately 70% of the Ciliwung River Basin area in East Jakarta falls into the highly vulnerable category, particularly in Kramat Jati and Jatinegara subdistricts.

%O Banjir merupakan salah satu bencana hidrometeorologi utama yang sering terjadi di Jakarta, terutama di sepanjang Daerah Aliran Sungai (DAS) Ciliwung. Penelitian ini bertujuan untuk menganalisis parameter yang berpengaruh terhadap kerawanan banjir DAS Ciliwung Jakarta Timur, menggunakan pendekatan spasial berbasis Sistem Informasi Geografis (SIG). Parameter yang dianalisis meliputi curah hujan, ketinggian lahan, kemiringan lereng, tutupan lahan dan densitas drainase. Data diperoleh melalui InaGeospasial dan Balai Besar Wilayah Sungai (BBWS) Ciliwung Cisadane, kemudian dianalisis dengan mean spatial dan skoring menggunakan overlay melalui ArcMap 10.8. Hasil penelitian menunjukka bahwa tutupan lahan memiliki pengaruh terbesar terhadap kerawanan banjir dengan bobot 26%, diikuti oleh kemiringan lereng (22%), curah hujan (18%), densitas drainase (18%) dan ketinggian lahan (16%). Pemetaan menujukkan bahwa 70% wilayah DAS Ciliwung Jakarta Timur masuk kategori sangat rawan banjir, terutama pada Kecamatan Kramat Jati dan Jatinegara.
