The quarantine process for koi fish at the Lelang Koi Nusantara event is still carried out manually, which increases the risk to fish health, particularly when water quality is not consistently monitored. As a result, koi fish may experience stress or mortality due to undetected changes in environmental conditions. This study aims to design and develop an automatic Internet of Things (IoT)–based control and monitoring system to improve the effectiveness of the quarantine process. The proposed system can detect key water quality parameters, including temperature, pH, ammonia concentration, water level, and turbidity in koi quarantine aquariums. Several sensors are employed, namely the DS18B20 temperature sensor, pH 4502 sensor, MQ-135 ammonia sensor, HC-SR04 water level sensor, and SEN0189 turbidity sensor, with measurement accuracies of 0.6 °C for temperature, 0.12 for pH, 0.26 for turbidity, and 0.2 for ammonia. Monitoring results are displayed through a web-based application integrated with MySQL and Firebase databases, allowing users to access real-time data and remotely observe water conditions. A forward chaining method is implemented to determine appropriate control actions, such as activating the heater, adding salt, or draining the water. System testing indicates that the proposed solution responds accurately to changes in water quality and supports better fish health management during quarantineReferences
