Floods are destructive, very detrimental, and require a long time to recover. To overcome the impact of flooding on the people of East Aceh Regency, research related to the mapping of flood-prone areas in East Aceh District. In the mapping process using Quantum Geographic Information System (QGIS) Desktop and the research methodology used is Composite Mapping Analysis (CMA) which consists of the process of determining the class of each parameter, determining the weight of each parameter by combining each parameter which includes the scoring process for each parameter, then overlaying the parameters used, performing calculations and producing a relative weight or spatial mean, and combining the spatial mean to produce a value for the weight of each flood parameter. The results of the study obtained the weight of rainfall of 23.85%; land slope parameter of 27.25%; the land height parameter is 24.7%5 and the flow density parameter is 24.15%, and the result is that the area of flood-prone areas has been divided into 3 classes, that is the very vulnerable class has an area of 230.099 ha (42.6%), the vulnerable class has an area of 224.732 ha (41.6%), and the bit vulnerable class has an area of 85.416 ha (15.8%). © Geoinformatics International.
