Application of Water Quality of pH and TSS Monitoring Using Online Monitoring at Settling Pond of Coal Mining Company PT XY

The existence of an Online Monitoring System is very important to know in real time the changes in water quality at Settling Pond so that it can immediately take action to maintain the quality of water from the settling pond always comply with the required environmental quality standards without errors resulting in mine closure and criminal sanctions. To face this challenge, a system needs to be developed that can monitor real time output water settling ponds, so that early warning can be provided if the settling pond requires special handling, to the team in charge. Currently water quality monitoring is still done manually, namely by doing water sampling and quality testing manually. This stage uses at least 12 teams to supervise 18 active, controlled settling ponds 24 hours and 7 days a week. In the implementation there were quite a number of challenges faced, apart from the fact that the Settling Pond location was quite far away so that it took quite a long time to reach the location. The applicable laws and regulations state that mine water management must not exceed the required environmental quality standard (BML) so that fast information is needed to be able to know water quality.
