Abstract

Changes in land use affect the amount of runoff that can seep into the soil. This problem can be found in Perumahan Dosen UNSRI. This can be overcome by rain water management such as Infiltration Trench and Rain Water Harvesting. This study aims to analyze the best scenario in rainwater treatment in the research area to reduce excess runoff that occurs. Daily rainfall data, land use, soil permeability, land measurement and existing drainage dimensions are used in the algorithm analysis. Determining the effective scenario is done by analyzing the algorithm and taking into account the BEP. The scenario which includes an infiltration trench with a depth of 1 m and RWH system with a tank volume of 2 m3 has the greatest average effectiveness of 55.33%, when compared to the scenario with an infiltration trench with a depth of only 1 m, it can be said that the RWH system brings an additional effectiveness of 23, 94%. Compared to the contrary, the addition of an infiltration trench only increased the effectiveness by 18.4%. The total cost of implementing the Infiltration Trench is 2 times that of the RWH System based by the calculation of the Budget Estimate Plan. The best scenario is determined, namely the implementation of a PAH system with a tank of 2 m3 in volume. This scenario has an average runoff reduction effectiveness value of 37.05% from the 3 years daily rainfall data used and a total cost of 1.8 billion Rupiah for all 194 houses.
