Abstract. This study aimed to implement a system based on the forward
chaining algorithm that can provide realtime information on irrigation and
soil feasibility. There are three aspects studied, namely, water level, soil
moisture, and temperature. The system developed uses an ultrasonic sensor
as a water level detector, a soil moisture sensor as a soil moisture detector,
and a DS18B20 sensor for measuring temperature. This system uses the
ISP8266 module NodeMCU microcontroller as a Wifi module and uses a
solar cell to utilize the sun as an environmentally friendly power supply.
Two tests were carried out including laboratory testing and field testing.
Laboratory testing shows that the system works with an accuracy of 57%.
Tests are carried out on the three aspects studied. Meanwhile, field testing
shows that some of the rice fields in Cekik Hamlet are not yet suitable for
processing based on the percentage of land feasibility. There are 8 (eight)
paddy fields with an average area of 25 square meters, and they are named
rice field B, C, D, E, F, G, H, and I. The test results show that the lands that
suitable for work are rice field B and rice field E. The feasibility value is
measured based on the level of water availability above 3 cm, wet soil
moisture with a value of 300 or below 300, and a temperature below 25
degrees Celsius. Validation was obtained from farmers, head of rice field
irrigation (Prajuru Subak), and agricultural extension workers. It can be
