Fuzzy Logic-Based Electrical Conductivity Control System in Aquaponic Cultivation

Cultivation technology in agriculture such as the aquaponics system is expected to be an alternative for people who have limited land or for those who want to simultaneously manage fish cultivation. Electrical Conductivity (EC) is one of the most influential parameters on plant growth in aquaponics cultivation. A good aquaponics system must have a controlled EC value. With technology, the EC value can be monitored automatically using the TDS sensor which is used to determine the number of dissolved nutrient particles. This study developed an EC content control system in aquaponics cultivation using Fuzzy logic control. The output of the fuzzy was the duration of the pump motor to drive the motor which will pour ABmix into the growing media of the aquaponics system. We did some testing to find out how well this fuzzy system performed. The results showed that this fuzzy logic system could control the aquaponics EC value. In addition, this fuzzy system fitted and ran well without overshoot.
