| Popis: | The Semarang River is a flushing channel for the city of Semarang which is located in the Semarang River Drainage Sub-System. This river has the potential to become a water tourism area with the application of the Historical River Front City Walk concept. However, the water contained in the Semarang River still comes from the inlet of the residential drainage system which still uses a mixed system. The largest land uses are in the form of trade and service areas as well as high-density housing. This study aims to determine the percentage reduction in pollutant loads in the Semarang River Drainage Sub-System by implementing Low Impact Development in the form of a permeable pavement along the Semarang River Inspection road. The research method used SWMM software with the wash off function in the form of EMC. There are 11 observation points in the study area, starting from the Simongan Weir Bridge upstream of the river to the Berok 2 Bridge in the Kota Lama Semarang area. The simulation results show that permeable pavement can reduce pollution load with an average % decrease in TSS by 2,01%, COD by 4,48%, BOD 5% and Nitrate by 0,96%. |
