In the future, climate change, especially temperature increase that occurs throughout the world is expected to pose a high risk both physic and social. As one of the coastal areas in Indonesia that has a high level of vulnerability to sea level rise, currently Semarang has experienced to inundation. Some areas in North Semarang such as Bandar Harjo and Tugu has been inundated and abandoned by its residents for quite a long time. The unavailability of information on disaster hazard prediction maps for future conditions is the background of the need for making accurate and actual flood hazard maps to minimize the impact of disasters. The combination between Geographical Information System (GIS) and Analytical Hierarchy Process (AHP) has been used to analyze and to determine the weight and score the risk map of Semarang City. As a result, 37% (141.403km2) areas of Semarang City are vulnerable to flood. This result is divided into 19 % high vulnerable, 13% moderate and 5% are low. By this, the flood risk map of Semarang City can be used by stakeholders and government to make a safe and resilience city planning.
