Abstract

Catfish farming is one of the most popular sectors in Indonesia's fisheries industry due to its high economic value and relatively short harvest cycle. However, the success of catfish farming heavily depends on the quality of pond water, such as temperature, pH, turbidity, and total dissolved solids (TDS). Manual water quality monitoring is time-consuming, labor-intensive, and often inaccurate. Therefore, this study aims to develop a prototype of an energy-efficient, Internet of Things (IoT)-based automatic monitoring and control system for catfish ponds, utilizing renewable energy from solar panels. The system uses an ESP32 microcontroller as the control center, integrated with four main sensors: DS18B20 (temperature), pH sensor, turbidity sensor, and TDS sensor. Sensor data is transmitted to an MQTT broker using the MQTT protocol, which is then forwarded to a web-based monitoring application in real-time. An automatic valve control feature is added to drain the pond water automatically if two out of three main parameters exceed the specified quality thresholds. The system's power supply is hybrid: the monitoring and control devices use a 20WP solar panel and a 12V 8Ah battery, while the solenoid valve is powered by an AC power source to ensure sufficient lifting torque. The INA219 and PZEM-017 sensors are used to monitor power consumption and voltage periodically. Test results show the system operates as designed with good accuracy: TDS sensor (maximum error 1.97%), pH (2.5%), temperature (1.65°C), turbidity reaching 45.20 NTU, and INA219 current sensor (0.90%). The automatic drainage system also functions effectively based on threshold logic. The entire system has proven to be accurate, efficient, and capable of real-time monitoring of pond water quality, thereby significantly supporting cultivation efficiency and energy savings.
