N2 - Management of rainfall runoff based on sustainable development, also known as nonstructural technology, is a new paradigm in stormwater management in urban and sub-urban areas. Jakarta, which is the capital of Indonesia, is an area with very rapid development, causing its buffer zones to also experience quite rapid development. Ciliwung is one of 13 rivers that flow north of Jakarta across the city. The Upper Ciliwung Watershed, which is a conservation area, has also experienced land cover changes that increase the peak floods and shorter flood travel times. As an effort to reduce the peak discharge and increase the travel time for flooding, the Ciawi and Sukamahi Dams were built in the Upper Ciliwung Watershed. The construction of the dam is an effort to manage rainfall runoff with a high spectrum. Green Infrastructure is a new paradigm of stormwater management which is defined as natural vegetative systems and green technologies to improve the environmental quality, social, and economic benefits that can minimize the bad impact of the climate change. The objective of this study is to analyze the performance of the implementation of green infrastructure technology on Ciawi-Sukamahi dams. The placement of stormwater management technology with LID technology was carried out with the help of Best Management Practices Siting Tools (BMP's Siting Tool) software. The effectiveness analysis of this technology was carried out using the HEC-HMS hydrological model which represents the spatial conditions and accommodates the hydrological processes in the Upper Ciliwung watershed. Based on the results of the analysis it is known that Ciawi and Sukamahi Dams can reduce the peak flood until 24% for 50 years return period. Combination of Ciawi and Sukamahi Dams with technology GI that is suited based on BMP’s Siting Tool model can improve the performance of Dams. The best performance of GI technology is shown at 2 years return period of rainfall that reaches up to 7%. That condition proved that GI effective to manage the small until moderate rainfall and gray infrastructure (Dam) effective for large and extreme rainfall.
