Design and implementation automation system for hydroponic vegetable cultivation

Abstrak

This research is about the design of an automation system by using microcontrollertechnology. The automation system defined in this research is the automation in the irrigationand fertilization process that has been designed by the needs for hydroponic vegetablecultivation, in an attempt to help hydroponic farmers and the community in controlling andcaring for vegetables automatically. The research stages are initiated from analyzing the needsof system development, continued by designing hardware and software, and implementingautomation systems for the last stage. The developed automation system consists of 1 module,1 sensor, Arduino Uno, and 2 relays and pumps. The RTC module is utilized to adjust thefertilizer scheduling time, while the utilization of a water level sensor is aimed to detect thewater level in hydroponic vegetable installations. Arduino Uno is utilized as a microcontrollerto process all data generated from the automation system. The data sent by the two sensors thenwill be processed to the objective of turning on the relay. In this system, 2 relays are used. Thefirst relay is a relay as a switch to turn on the water filling pump and the second relay is a relayfor the fertilization pump. Furthermore, the automation system is equipped with 2 pumpsaiming for filling water and fertilizing hydroponic vegetables. The working system is repeatingeach instruction regularly according to the program instructions that are made. This researchhas succeeded in making a prototype of an automation system for hydroponic vegetables, it ishoped that this prototype can be used by farmers and the general public in hydroponicvegetable cultivation to achieve more satisfying results.
