Sprinkler Irrigation System for Pakcoy Cultivation Based on Mamdani Fuzzy Logic and LoRa Communication

The use of water in manual irrigation systems is often uncontrolled resulting in inefficient use of water which will affect costs. Sprinkler Irrigation System is an irrigation technique by spraying water into the air with a sprayer so that the water is distributed evenly. This irrigation method is one of the solutions to optimize water use in the agricultural sector. Monitoring using the wifi network is still a problem because wifi cannot reach remote areas, so it is not suitable for highland areas with heterogeneous land contours. This research focuses on developing a Sprinkler Irrigation System to control the duration of watering so that water use is efficient and monitoring using Lora Communication to overcome network problems in highland areas. The method used is Mamdani Fuzzy Logic with two parameters, namely temperature and humidity. Meanwhile, monitoring uses LoRa Communication which can reach a distance of up to 15km. The results show that a sprinkler irrigation system using Mamdani Fuzzy Logic can provide water use efficiency of up to 31.81 %, while the use of LoRa communication in monitoring shows that the maximum range of LoRa is 100 meters.
