Load Capacity of Water Pollution of Jaing River in Tabalong

Jaing River is part of the 39 km long Barito watershed in South Kalimantan which disembogues into Tabalong River. Jaing River is classified as class I (one) river that is designated as a source of drinking water. The large number of activities in the bank of the river has a potential to reduce the quality of the river. Field observations revealed that some activities created several pollutions and also run off of production waste into the river. Thus, the purpose of this study was to analyze the load capacity of pollution of Jaing River. The study was carried out in Jaing River as far as 39 Km in TabalongRegency and the river water quality was analyzed at 3 sampling points using physical, chemical and biological parameters. The analysis of quality and determination ofload capacity of water pollution used Mass Balance Method. Finally, the results obtained from this study are (1) the BOD pollutant load value of 418.87 kg/day, the value of COD pollution load of 2018.90 kg / day and the value of TSS pollution load of 1698.14 kg/day. (2) The value of pollution load capacity (DTBP) for BOD parameters is 246.07 kg/day, COD parameters are 1154.90 kg/day and for the TSS parameters are 2621.86 kg / day.
