Abstract

The percentage of clean water in Indonesia (2019) is achieving 72,55% out of 100% based on SDGs’ standardization. One of hazardous materials that still exists in water commonly is Iron (Fe) which is going to trigger the complications in body if only it is already maximum. The research of sensitivity measurement system aims to identify Fe’s existences < 1 ppm for its concentration. This optimization applies potenciometric method with Ion Imprinted Polymers basis using ESP32 in order to uplift the effectiveness uses, so it will be connected to WiFi or bluetooth while there is no internet connection. The instrument consists of ADS1115 to convert voltage of potenciometric to concentration, DS18B20 to measure liquid’s temperature, and SKU SEN0161 to monitor liquid’s pH. The optimization of the system had been tested in range 0.1-1.0 ppm of Fe(III) liquid’s concentration with %recovery= 102.2667% , %RSD = 15.9915% , and error = 5.1959%.
