Disaster vulnerability in rural and riverside areas of Indonesia remains a significant issue that requires risk identification based on spatial and social data. This study aims to map disaster-prone houses in Hambau and Genting Tanah Villages, Kembang Janggut Subdistrict, Kutai Kartanegara Regency—areas frequently affected by floods and landslides. A descriptive-quantitative approach was employed, including field surveys, physical observation of buildings, community interviews, and mapping using Geographic Information Systems (GIS). Risk assessment was conducted using a multi-criteria approach and the Analytical Hierarchy Process (AHP) to assign weights to physical, environmental, and social indicators. The results revealed that 35% of houses in Hambau and 28% in Genting Tanah fall into the high-risk category, while the remaining houses are categorized as moderate or low risk. High-risk houses typically have fragile structures, are located near riverbanks or at the base of unstable slopes, and are inhabited by vulnerable groups. Spatial mapping indicated a concentration of high-risk zones (red zones) along the river, underscoring the need for evacuation planning and structural reinforcement. This study concludes that community-based mitigation, integrated with both technical and social considerations, must be urgently implemented to enhance regional resilience against recurring disasters.
