Abstract

Hydroponic system is the cultivation of plants without soil and using only nutrient solutions in water. The concentration of these nutrients needs to be adjusted before being given to plants. If the nutrients given are too concentrated, the plants will die or wilt, on the contrary if the concentration is low, the plants will lack nutrients. The automation system for regulating nutrient concentrations in this study is based on a PID controller using nodeMCU. The setpoint is the reference nutrient concentration value which is compared with the current concentration output measured by the sensor to get an error. If the error is positive, it indicates that the plant is on the verge of nutrient deficiency so that the nutrient solution valve needs to be opened to increase the concentration of the solution. On the other hand, if the error is negative it means that the concentration of the solution exceeds the value it should have, so the water valve needs to be opened to reduce the concentration that occurs. The test results show that the PID controller with Kp=0.8, Ki=0.5, and Kd=0.5 gives a fairly good response and a relatively smaller average error of 3.92.
