Abstract

The inhibiting factors for plant and fish growth in aquaponics systems are farmers who never control and monitor the quality of Dissolved Oxygen (DO) levels and the degree of acidity/Power of Hydrogen (pH) of water properly. Uncontrolled and monitoring of the quality of pH and DO in water properly and periodically will have an impact on the process of nitrification and denitrification of the aquaponics system. Therefore, it is necessary to update the technology on the aquaponic to automatically maintain the DO and pH parameter to balance the ecosystem. To design a control system, a series of validations are carried out on the sensors used. The MSP340 pH sensor has an average error of 2.58% and an accuracy of 97.42%. The DO sensor SEN0237-A has an average error of 4.82% and an accuracy of 95.18%. The ultrasonic sensor has an average error of 3.14% and an accuracy of 96.86%. Based on the comparison of parameter values before and after the control system was installed, the pH value was still in the neutral pH range (6.5–8.5). While the DO value tends to be below the predetermined setpoint (1–5 mg/l). Based on the comparison of growth rates, it was found that the average plant growth rate decreased from 13.4% to 12.5% during the two weeks of the study. However, the length of the plant increases to 0.2 cm. The fish growth rate increased in the first week using a control system up to 17%, survival rate reached 100% in the second week .
