DESIGN OF A MONITORING SYSTEM FOR SOIL AND AIR CONDITIONS IN MEDICINAL PLANT CULTIVATION BASED ON IOT (INTERNET OF THINGS)

Abstract

Medicinal plants have been known to Indonesian people since ancient times and have become a very important addition to supporting human survival. In general, medicinal plants can be planted in rice fields or fields, in the highlands and lowlands. The conditions needed for chili plants to grow well are soil height, soil type, water, air temperature and humidity.
Humidity can be in the form of humidity in the air or soil moisture. Modifying the microclimate around chili plants is an effort so that cultivated plants can grow and develop well. Air and soil humidity, air and soil temperature are microclimate components that greatly influence plant growth, and each is related to creating optimal environmental conditions for plants. Soil moisture can affect the growth of medicinal plants. Soil moisture corresponding to the characteristics of medicinal plants is around 69.2%, 69.6%, 70.3% and 70.8%. The optimal air temperature for medicinal plants is 25-30°C. The lower the soil and air humidity, the growth of medicinal plants will not be optimal, the plants will experience stunting and the higher the soil moisture level and the higher the air temperature, the more medicinal plants will wilt.
In designing this monitoring, the author uses fuzzy logic to support detection accuracy in soil and air monitoring in medicinal plant cultivation. Fuzzy logic is a calculation method that uses linguistic variables or words, as an alternative to calculations using numbers. Meanwhile, in previous studies, researchers did not use a fuzzy logic system to support detection accuracy in soil and air monitoring in medicinal plant cultivation.
