Simulation of Bod and Cod Pollutants Distribution in Tello River Makassar City

Abstract

Water quality management and water pollution are one of the natural resources that have a very important function for human life that must be managed and secured from the conditions of pollution, therefore efforts are needed to monitor and monitor river water quality. In connection with that, a study was conducted aimed at assessing changes in water quality in the Tallo River through the distribution of pollutant concentrations of BOD (Biological Oxygen Demand), DO (Dissolved Oxygen) and COD (Chemical Oxygen Demand) by analyzing the mathematical model approach in the form of Surface Software Water Modeling System (SMS 8.1) integrated with RMA2 and RMA4. The research method carried explanation was a field survey in the form of data collection of water as many as 5 points in the drainage along the Tallo River. Simulation results show that based on water content requirements in the Republic of Indonesia Government Regulation No. 82/2001 regarding water quality standards it is known that for existing conditions and simulation results it is known that the classification of estuary river water conditions based on Dissolved Oxygen (DO) content is classified as Class 4 and the content of Biochemical Oxygen Demand (BOD) is classified as class I and the content of Chemical Oxygen Demand (COD) is categorized as class IV.
