FKGG (Forum Komunikasi Gunung Geulis) is a model farming and gardening community located in Jatiroke, Jatinangor. This community features two different types of gardens: a conventional garden using soil as the growing medium and a hydroponic garden using water as the growing medium. Two years ago, the farmers at FKGG manually maintained and monitored the gardens, requiring significant labor. Last year, developers from SCCIC and STI ITB conducted community service to assist FKGG farmers by creating an Internet of Things (IoT) based system for garden maintenance and monitoring. However, upon review, the installed tools were not fully optimal. There were several aspects that could be improved, such as the microcontroller restarting every time the pump was turned on, dependency on internet connection, and the absence of on-site control mechanisms. Therefore, further development of the existing system was undertaken to enhance system reliability and reduce dependency on internet connection. This report details the design and implementation of hardware for automation in conventional and hydroponic farming. The implemented hardware is characterized by safety, reliability, and versatility, as it can function well in various situations for both conventional and hydroponic farming systems. This hardware also has built-in redundancy and fail-safe mechanisms for unexpected events. For the conventional farming system, the hardware is designed to control water pumps and solenoid valves for scheduled irrigation purposes. Additionally, this hardware can read environmental data, such as soil moisture, water availability, and water flow. For the hydroponic farming system, the hardware is mainly designed to control water pumps and peristaltic pumps for automatic dosing purposes. Additionally, this hardware can read environmental data such as pH levels, ppm levels, and nutrient solution availability. After thorough testing, all hardware subsystems have functioned well. The successfully tested subsystems include (1) the power management unit, (2) sensor interface, (3) actuator interface, (4) human-machine interface, (5) main controller and supporting components, and (6) wireless transceiver.
