ANALISIS PENAMBAHAN NUTRISI PADA TANAMAN HIDROPONIK BERBASIS INTERNET OF THINGS

In an increasingly advanced era, electrical energy has become a basic resource for humans, the wider and more equitabledistribution has greatly influenced the progress of all sectors of electricity users. However, on the other hand, this hydroponic businessrequires precision and special attention by the actors to support the maximum success of the hydroponic business. Several previous toolshave been able to overcome the problem of irrigation for hydroponic plants. However, there is no tool that can regulate the addition ofnutrients based on the internet of things and monitor the hydroponics. So, a tool for adding nutrients to hydroponic plants based on theinternet of things was designed that is equipped with supervision on plant nutrition. It is hoped that after the manufacture and analysis oftools on hydroponic plants can overcome the problems that are often experienced by hydroponic entrepreneurs.The research wasconducted from May to July 2022 in Margoutomo Dalam, Dau, Malang. This nutrient addition tool is designed using an Arduino Unomicrocontroller where as a regulator and NodeMCU is added as an online access on the user's cellphone. After the tool has been designed,a regression analysis is carried out to determine the effect of nutrient levels on the fertility of hydroponic plants. The results of this studyshowed that the nutritional value of a good plant was 350 ppm, with the response rate of this nutrition enhancer at 1.62% per second at adistance of 338 km for testing the user.
