Abstract

The availability of safe, clean water is fundamental to human health and well-being, but a growing issue is that natural water sources are increasingly contaminated by various pollutants, especially in mining areas. The water source in the mine comes from rainwater and is collected in a lake used for mining activities, so the water conditions tend to be murky and contain many hazardous chemicals. World Health Organization (WHO) and the Regulation of the Minister of Health of the Republic of Indonesia number 2 of 2023 state that clean water that is suitable for MCK is water that is not cloudy, colorless, temperature between 15 - 35 °C, free of chemicals or with a pH between 6.5 - 9, and Total Dissolved Solids (TDS) water no more than 1000 ppm. The purpose of this research is to provide water quality monitoring at the Water Treatment Plant (WTP) in the coal mining area based on the Internet of Things (IoT). The IoT product created, namely the water quality monitoring system, has several main advantages. This system can monitor water pH, water TDS, water temperature, and water turbidity, and display data in real-time on the monitoring website. On the website, sensor data is displayed in the form of charts, allowing users to monitor significant changes in data. In addition, there is an export feature to excel that makes it easier for WTP technicians to make reports. The tool testing technique is carried out using 15 water samples, the result is that the pH sensor has an accuracy rate of 97.93%, the TDS sensor has an accuracy rate of 99%, the temperature sensor has an accuracy rate of 98.58%, and the turbidity sensor shows a value that matches the water sample used. The results of this study indicate that the IoT system created is effective in monitoring important parameters such as pH, TDS, temperature, and turbidity of water in real-time, which can improve operational efficiency at the WTP and assist technicians in monitoring the WTP which was previously done manually.
