IMPLEMENTATION OF FUZZY LOGIC METHODS IN NUTRIENT CONTROL IN HYDROPONIC PLANTS

Hydroponics is a farming technique using water media that contains nutrients that plants need to grow and develop, therefore we must be careful in maintaining the nutrient content that is usually stored in a reservoir. This is the main problem if we cannot maintain optimal nutritional conditions in the reservoir, plants that lack nutrients will affect their growth, otherwise, plants with excess nutrients will quickly rot and turn yellow. Therefore, we need a tool that can control the levels of hydroponic nutrients in the reservoir. We need a tool that can control the hydroponic nutrient reservoir based on a microcontroller in which fuzzy logic is embedded. Fuzzy logic itself consists of many rules that can regulate the output of the output pump which consists of a nutrition pump and a water pump, the output is in the form of a delay value which will be used to turn the relay on and off. As we know hydroponic farming requires patience and accuracy in managing the nutrient reservoir, with this tool we no longer need to worry about nutrition for plants because everything is fully controlled by a microcontroller, for further it is hoped that this tool that already contains fuzzy logic can work continuously to control nutrient levels in the reservoir.
