Hydroponics is one of the modern methods of farming that is widely used by the society. However, hydroponic practitioners generally still use manual methods in optimizing nutritional parameters in hydroponic liquids so it requires a lot of time and energy. Therefore, a precision hydroponic nutrition management system was developed. The developed system consists of five subsystems, namely the sensor subsystem, the control and data processing subsystem, the actuator subsystem, the communication subsystem, and the user interface subsystem. This final project document specifically aims for hardware design of the system, especially in the sensor subsystem and control of sensors in this precision hydroponic nutrition management system. The program source code was made using Arduino IDE and then uploaded to the microcontroller. Sensor components are installed on the microcontroller according to their respective functions. This system is then tested to see whether all subsystems are running well or not, then tested using plants in real conditions. The sensor subsystem has succeeded in detecting all parameters of the hydroponic growing media, while the control subsystem has managed to process the data reading of the parameter values for further use as a basis for instructions for the actuator subsystem in hydroponic nutrition management and the data is also displayed to users through the communication and the user interface subsystems.
