The government has begun to develop Green Infrastructure in every stage of infrastructure development in the capital, especially in areas that often experience of floods. The application of green infrastructure with the concept of eco-drainage in the drainage system in the Kelapa Gading area is a hope for holistic benefits from an environmental perspective. This study aims to find a flood control model based on eco-drainage through a feedback system between all components in the flood control system and to find out the optimal scenario as the basis for recommending flood control policies. The analytical method of this research uses a dynamic system approach, which is a modeling method of a dynamic and complex system. by forming a certain scenario based on elements that interact with each other in the form of feedback or Causal Loop Diagrams. In this dynamic system, the problem will be seen as a whole based on the relationship between variables that influence each other. The development of a dynamic system model will be assisted using the Powersim Studio Version 10 software. The results of this study have revealed, based on the built model, that use of eco-drainage has benefits in groundwater conservation (S = 15.56), suppression of the rate of land subsidence (S = 1.001), and decrease the flood rates (s = 0.67). According to the simulation between the existing and moderate scenario, the moderate scenario is the best solution. This finding has important implication for the strategic policies implemented. The strategic is the policy of limiting the use of groundwater by 10%, the construction of 3500 eco-drainage points, and the use of polder infrastructure in Kelapa Gading with a pump capacity of 7 m3/s as many as 2 units. This study also has implication the optimal amount of eco-drainage depending on the saturated condition of the soil layer. [ABSTRACT FROM AUTHOR] |
