Abstract

Direct disposal of untreated laundry wastewater contributes to environmental pollution, with TSS (Total Suspended Solid) levels reaching 600 mg/L, far exceeding the 100 mg/L limit set by East Java Governor Regulation No. 72 of 2013. This research aims to develop an automated treatment system using an ESP32-S3 microcontroller integrated with pH, TSS, and temperature sensors, with real-time monitoring through the ThingsBoard platform. The DC motor serves as an actuator for the mixing and chemical feeding process. System testing showed the DC motor control had a 100% rate in processing TSS levels and 95% in reducing pH levels. On IoT data transmission, the average delay was 4 seconds for turbidity and 5 seconds for pH. Processing effectiveness was classified as 71% “Feasible,” 5% “Very Feasible,” and 19% “Less Feasible.” While there are some limitations, the system shows potential for adaptive wastewater treatment, which requires further improvements in sensor calibration and control reliability.
