Abstract
Hydroponic farmers have several obstacles, one of which is controlling nutrition manually, which required extra energy and additional time. Therefore, it is necessary to control the concentration of the solution so that the results of cultivation using hydroponic techniques can obtain the maximum level. This research aimed to design an IoT (Internet of Thing) based NFT hydroponic nutrition control system. This study used an experimental method by observing Pakcoy plants in the NFT hydroponic system with two treatment variations, i.e., without controlling the nutrient solution and controlling the nutrient solution based on IoT. NodeMCU is an IoT platform that is open-source. The hardware consists of the ESP8266 System on Chip from the ESP8266 made by Espressif Systems and the firmware used, which uses the Lua scripting programming language. This research has produced a nutrient solution control tool using IoT-based NodeMCU, monitored via Blynk and Thingspeak. The height and weight of the plants produced by using the control system (19 cm and 18.4 grams) were better than the plants without control (15 cm and 9.21 grams).
