Abstract
The impact of tidal flooding due to the influence of land subsidence and sea level rise on the coast in Jakarta has been categorized as a disaster. Losses economically have reached tens of trillions of rupiah and even hundreds of trillions when we take into account the costs of mitigation. Due to the nature of the disaster, coastal disaster risk management for tidal floods and land subsidence as well as sea level rise is mandatory, where one of the stages is to conduct a time series analysis of tidal floods that occurred on the coast of Jakarta. This time series can be used as an input parameter for effective mitigation and adaptation measures for tidal floods and land subsidence and can even be used as a parameter for evaluating the implementation of mitigation and adaptation itself. Hypothetically, if the time series shows that there has been an expansion of tidal flooding, mitigation and adaptation efforts still need to be addressed, conversely, if from the time series there is a reduction in the tidal flood area, this can be an indicator of successful mitigation and adaptation. Result of investigation shows decreasing number of places suffered coastal inundation through times.
