Clean water quality monitoring system at PAMSIMAS based on conductivity, alkaline acidity and turbidity level using the internet of things.

Water is one of the essential elements of basic biological needs for creatures on earth. Water is needed in daily activities ranging from cooking, washing, bathing, eating, drinking, and is also used in various sectors, including the industrial and agricultural sectors. PAMSIMAS is a government program for the provision of community-based drinking water and sanitation to provide services in the form of providing clean water that is suitable for consumption. According to the Regulation of the Minister of Health of the Republic of Indonesia regarding the quality requirements of clean water that is safe for health and good for consumption, namely having a maximum level of water turbidity 0-25 Nephelometric Turbidity Unit (NTU) and having a Potential Hydrogen (pH) base acidity of 6.5-9.0 and has a Total Dissolved Solid value (TDS) 50-150 ppm. The number of PAMSIMAS in areas that have not been monitored for clean water quality, so it is necessary to develop a monitoring system to determine whether clean water is suitable for consumption. In this study, for testing each sensor used, namely TDS sensors, Turbidity Sensors and pH sensors, a reading error rate of 1.66% was obtained for TDS sensors, 4.36% for turbidity sensors and 1.01% for pH sensors. From the results of monitoring clean water quality at PAMSIMAS Ngeling Village, Jepara Regency, data were obtained to monitor the turbidity level of a solution on average 21.2 NTU, the average acidity level of 7.01 and the average conductivity level of the solution 82.01 ppm, from these results clean water on PAMSIMAS is suitable for consumption.
