The parameters used to monitor and determine the quality of river water are divided into physical, chemical, and microbiological parameters. In chemical parameters, especially dissolved metals, there is also
mercury (Methyl Mercury / Hg) which is very dangerous. Even water that is exposed to mercury cannot be purified in any way. Research on water quality by the Jambi Regional Environment Agency at 16 points found that the Batanghari category is now heavily polluted (Class D), allegedly due to waste water from Gold Mining Without Permits. The need for raw water for residents throughout the Batanghari River area is an urgency to always maintain its quality. To determine the development of water quality, especially in the dissolved metal content which is dangerous and is the main pollutant of illegal gold mining activities such as methyl mercury / Hg, an effective and efficient technology is needed so that it is expected to be able to read the level of contamination in water in real time. the purpose of water quality monitoring is to match whether the water quality monitoring results is in accordance with the standard of use / consumption. internet of things technology is applied using raspberry pi with several sensors including a pH sensor, color sensor, TDS electrolyzer, and a mobile application that is used to monitor data in real time. Electrolysis technique used as a whole can work well, although there are still errors with an average value of 2.32%. The mercury contamination monitoring tool will produce data output in the form of a summary of the mercury contamination category, pH, and water turbidity level. Then the output that has been generated in real time is sent via the Module Shield Sim800 GSM component to the server and can be monitored through the Methyl Mercury Contamination Monitoring Application.
