Abstract

ABSTRACT The success of a floating hydroponic system depends on the management of the solution's nutrient content. Monitoring and regulating nutrient levels is still conventional, which takes time and effort. Therefore, an automated system is needed that can control nutrient concentrations accurately and in real-time. The purpose of this study is to monitor and control nutrient levels and determine the efficiency of the TDS sensor on the Arduino UNO R3 microcontroller automatic control device. This research was carried out from October 2023 until it was completed at the Plant House of the Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. The methodology includes functional and structural design, microcontroller-based monitoring and control systems, as well as demonstration testing of automatic hydroponic nutrient control devices, evaluated based on parameters, accuracy, precision, and error percentage. This study used a nutrient concentration of 500 ppm during week 2 and 600 ppm during week 3, using AB Mix nutrition every hour for 12 hours per day, measured using Arduino UNO R3 and a TDS meter. At the measurement of the concentration of 2 WAP of 554 ppm, at 3 WAP, it increased to 657 ppm. The accuracy level showed quite good performance with an average of 89% at 2 WAP and increased to 91% at 3 WAP. The Precision value increased from 2 WAP by 13.58% to 7.81% at 3 WAP, indicating an improvement in the consistency of tool performance. The average error rate in nutrient measurement of 11% on 2 WAPs decreased to 9.7% on 3 WAPs. The results showed that although the automatic control device has not yet achieved accuracy and precision, the measurement error value was in the range of 10-11%, which was still tolerable in hydroponic applications in the field, thus making this system an applicable technology and contributing to the development of smart farming. The conclusion of this study showed a positive correlation between the Arduino Uno R3 Microcontroller TDS sensor and the TDS meter, with a correlation coefficient value of 0.56 at 3 WAP (Weeks After Planting) on the growth of pak choy plants, which indicates a linear relationship with a directly proportional trend.
