Pemantauan Kualitas Air Sumur Di Kabupaten Bantul Menggunakan Sistem Internet Of Things (Iot) Dengan Sensor Total Dissolved Solid (Tds)

Abstract

Water quality in Selogedong Hamlet, Rt.60, Bantul Regency is a concern due to the high lime content and the potential influence of Mount Merapi's volcanic activity. High TDS content can have a negative impact on health and household infrastructure. However, water quality monitoring is still done manually, which takes time, effort and money, and does not allow direct detection of changes. Therefore, this research aims to develop an IoT-based water quality monitoring system with TDS sensors to provide direct data and support more accurate clean water management.

Data collection was carried out on 15 well water samples in Selogedong Hamlet, Rt. 60, Bantul Regency. The system uses an ESP8266 microcontroller with TDS and temperature sensors, measurement data is sent via a Wi-Fi network to the Blynk platform, which can be accessed via a smartphone application. This method allows for more efficient monitoring than manual methods, with testing carried out in three stages to ensure system accuracy over time.

The measurement results show that TDS levels at several location points exceed the WHO recommended threshold, with a TDS range of 280–564 ppm in the first stage, 349–538 ppm in the second stage, and 327–529 ppm in the third stage. Mark Electrical Conductivity (EC) and Well water temperature varied from 28.38°C to 29.38°C, with a slight increase in the third test stage. The 7th sample had the highest TDS level (564 ppm), indicating a high content of minerals or dissolved substances. This IoT-based monitoring system has proven effective in providing direct water quality information, so that it can help the community and government in managing water resources.
