<p align="justify">Hydroponic plants have parameters that must be monitored and kept within their ideal range. With automatic hydroponic plant monitoring and control, users can easily monitor and control hydroponic plant parameters. The environmental parameters to be maintained are the pH, conductivity, and temperature values. In this research, the hydroponic system technique that being used is Nutrient Film Technique (NFT) which is by flowing water to plant continuously. In this MoCoponic system there are several system controllers such as pH controller and temperature controller. The parameters are monitored using sensors and controlled by using the pump either mixing the pH up and down pH solution as well as draining water to the coolant. <br /> <br /> <br /> The results obtained are in accordance with the specifications of MoCoponic. In the pH controller, closed loop with precalculated output is used for the control system. And for the temperature controller, simple on / off closed loop is used for the control system. In the pH controller a lookup table graph is used to estimate the given control solution while the temperature controller only compares the current temperature with the set point temperature. <br /> <br /> <br /> The hydroponic parameters can be monitored and controlled automatically by using sensors for monitoring and pump for control. The lookup table characteristics of the pH controller can only be used with the same type of control solution so that for further development the controller is expected to be used for different types of control solutions. <p align="justify"> <br />
