Most farmers grow tomatoes in conventional ways in the fields, fields or plantations without the control and measurement relying on experience and habitual factors, so the need for pH and temperature of the planting space of tomato plants cannot be given according to their needs, while the pH requirements of tomato plants range from 4 , 5 to 6.5 and the planting room temperature is 23 ° C to 32 ° C, and soil moisture is 25% - 75%, using the hydroponic drip planting method which is automatically controlled by the Arduino-based microcontroller with the application of fuzzy mamdani making it easy to do pH setting of planting media using soil pH sensor as input and temperature of planting room using LM35 temperature sensor, and soil moisture sensor using humidity sensor fc28, as the system output fan and selenoid valve are used. To find out plant nutrition, one of the indicators is the pH value of soil media, room temperature and humidity of the planting medium.Tomato plants whose nutrients are automatically controlled using the fuzzy mamdani method can produce more fruit, which is 24 fruits with a plant height of 75cm compared to plants without using tools, only 14 pieces with a height of 64cm. And it was found to be sweeter at 7.6% compared to only 5.2%.} }
