A Smart Aquaponics System: IoT-Driven Water Quality Control for Lettuce Cultivation

The increasing world population will be linear with the need for food from both livestock and agriculture. Food security is an essential issue for all countries, including Indonesia. However, most of them need more agricultural land. Therefore, alternative agricultural technology is needed to meet food needs. Aquaponic technology is one solution that modern farmers have widely applied. Aquaponics allows the growing of vegetables along with fish farming. Maintaining water quality is one of the important parameters in aquaponic to ensure the quality of vegetables and fish in addition to environmental conditions. In the context of aquaponics, despite the high potential benefit of automation, there are still many water quality inspections rely on using manual methods. By performing automation in aquaponics, it may significantly affect the production efficiency and quality because automation is able to provide continuous and accurate monitoring. This study designed a mobile water quality monitoring system in aquaponics. The proposed system is implemented using an Internet of Things (IoT) platform. The water quality parameters measured included pH, temperature, and turbidity. The IoT user interface application is built using the Blynk platform. The developed system has been implemented for aquaponics monitoring in Purwakarta, West Java, Indonesia. This innovation meets the urgent demand for effective oversight and administration in aquaponics systems.
