Langsa City is a city located in Aceh Province, Indonesia. Recently there was heavy rain in the upstream area of the Krueng Langsa River Basin, which resulted in flooding in the area and overflowing of the river in Langsa Kota Subdistrict, Langsa City, Aceh. According to the head of the Aceh Disaster Management Agency (BPBA), Sunawardi, the overflowing of the Krueng Langsa hit the Java Rear Village and Seulalah Village with the water level reaches 50 centimeters. The purpose of this research is to identify studies of flood disaster risk in flood prone areas in Langsa City, and formulate flood mitigation-based strategies for disaster mitigation in flood prone areas in Langsa City. This research uses quantitative analysis method with overlay/superimpose analysis approach to analyze the level of vulnerability, hazard level and risk level of flood disaster. Strategy for flood mitigation based on disaster mitigation in flood prone areas in Langsa is divided into two, namely: (1). Structural mitigation in the form of explanations regarding the construction of flood control buildings such as making embankments, making drainage network structures, and making drop structures; (2) Non-structural mitigation in the form of training and simulation of disaster mitigation, as well as evaluating policies on reducing the risk of flood disasters in flood prone areas in Langsa City, Aceh, Indonesia.
