IMPLEMENTASI FUZZY LOGIC UNTUK MENGATUR KEBUTUHAN NUTRISI HIDROPONIK SISTEM NFT (Nutrient Film Technique)

Abstract

Nutrition is one of the basic needs that need to be considered in hydroponic plants. Planting with Hydroponic system is planting by using water as a planting medium, a good nutrition feeding and regulation system is required, one of which is the NFT  (Nutrient Film Technique)system, which utilizes the circulation of water, nutrients and oxygen for the living needs of plants. It takes manual power to monitor nutrient levels and improve it, this is a lot of time-consuming for the owner. has been successfully implemented hydroponic nutrition regulatory tools with  fuzzy logic method to regulate the ppm content and pH of nutrient solution. By utilizing the analog TDS meter sensor and pH meter as input. Hasi; test on the system produces a pretty good accuracy value, which the system has been able to maintain normal conditions or conditions according to the setpoint  where the state is a necessity of plants. This system is designed to regulate the nutritional needs of the first week with a setpoint of 500 ppm and the second week with a setpoint of 700 ppm.
