Perancangan Sistem Kendali Irigasi dan Kontrol Nutrisi pada Tanaman Hidroponik Berbasis IoT

Abstract

Hydroponics is a technique of cultivating plants without using soil, but using water as the main medium. The benefits of hydroponic techniques such as saving land use, being able to produce healthy and sterile plants because they are free from plant pests. Various kinds of plants that can be developed in this technique such as chili, tomatoes, mustard greens, pak choi, lettuce, kale, spinach and others. Spinach growth is at pH 6-7 with a harvest period of 23-30 days. Spinach is then developed into a hydroponic plant. In hydroponic management is still done manually. Therefore, IoT-based hydroponics was created. Where in this system uses a pH sensor to measure the acidity and alkalinity of a solution. Data from the pH sensor will be displayed on the LCD and displayed in the blynk IoT application. If the pH is below 5.5 then the pH will automatically be added. Nutrient control and irrigation in hydroponic plants are controlled via android which is connected to wifi by pressing the on/off button on the blynk IoT application. Providing nutrition is the main thing in hydroponics be-cause nutrients are food or plant needs. Utilization of IoT makes it easier for hydro-ponic managers to be able to monitor plants remotely.
