Flood Management Model in Digital Era, Using SAST (Strtategic Assumption Surfacing and Testing) and the Exponential Comparison Method (ECM): A Case Study in Jakarta

Flooding is a regular annual disaster in Jakarta, especially in December to February. Geographical position of Jakarta which is 40% below sea level, causes flooding not only from rain, but also from rob due to rising sea levels. In the last 5 years the impact of flooding became more serious, leading to economic and human losses.

This study aims to determine the right strategy of flood mitigation by public involvement in the digital era. The method used includes combination of quality input data from experts representing BNPB (National Disaster Agency), Local Goverment, Academics, Community Leaders, Businessmen, and Practitioners, in addition to vulnerable field research. Data analysis uses the ECM (Exponential Comparison Method) and SAST (Strategic Assumption Surfacing and Testing).

The result of the study indicates that the most appropriate strategy to mitigate flood disaster is establishment of “Disaster Information Center” and "Disaster alert groups” involving every stakeholder from the community. Utilization of social media, especially WhatsApp, Facebook, and Instagram has been very helpful to share information of flood, especially how to prepare an emergency action to reduce economic and human losses.
