N2 - It is necessary to design an instrument using optical fiber as a soil moisture sensor, which can be implemented to detect potential landslides. The paper describes the sensor design, the experimental setup and an example of sensor prototype. This study uses multimode plastic optical fiber, light source from IF E91A IR LEDs that connected with Arduino, and OPM software for data retrieval. The POF's removed cladding is 6 cm long. Using the U-bent method with diameter variation of 35 mm, 30 mm, and 25 mm, the optical power decreases along with the increase of water content in the soil. The sensitivity obtained for 35 mm, 30 mm, and 25 mm diameter are 0.245 μWatt / %, 0.154 μWatt / %, and 0.437 μWatt / % respectively. The use of U-bent method with 25 mm diameter has a better performance because of its larger sensitivity than the other diameter variation.
