What is it about?
Mining activities and community activities around the Way Umpu River have the potential to be the main source of the decline in the water quality of the Way Umpu River. Therefore, to determine the level of pollution in the Way Umpu River, it is necessary to test the quality of river water using several chemical and physical parameters such as TSS (Total Suspended Solid), DO (Dissolved Oxygen), BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), and Phosphate. The study aims to study the differences in levels of TSS, DO, BOD, COD, and phosphate in river water before and after the mining location. The research is an observational study. Samples were taken from two points, namely the upstream (before the mining location) and the downstream (after the mining location). The average result after the analysis test is then compared with the river water quality standard in accordance with the provisions of Government Regulation no. 11 of 2012 concerning class III river water quality standards. There is no significant difference before and after mining location for the average levels of TSS, DO, BOD, and Phosphate parameters (p-value > 0.05). In the COD parameter, there is a significant difference (p-value < 0.05). Overall, the average yields of TSS, DO, BOD, COD, and Phosphate after the mining location have met the quality standards set out in accordance with Government Regulation. Therefore, it can be concluded that mining activities and community activities around the Way Umpu River have not completely decreased the water quality of the Way Umpu River in the last four years.

Why is it important?
The Way Umpu River is one of the rivers that is the location for gold mining. The gold mining is considered to be a major polluter in river waters. Besides, various land use activities in the area around the Way Umpu River such as settlement, agriculture, fishery, mining, and industrial activities seem to have affected the quality of water from Way Umpu River.
