An experimental study has been conducted to analyze the losses due to the fiber optic macro bending to be applied to the flood sensor. Optical fiber macro bending occurs when an optical fiber is bent with a radius wider than the radius of the optical fiber. Data retrieval is gathered by measuring the change in the value of the light intensity due to the presence of symptoms bend (macro bending) on optical fibers that cause the symptoms of losses optical fiber application that read in Arduino IDE. Optical fibers used are plastic optical fiber diameter of 0,3 mm and light sources are red LED (610 < λ < 760 nm). The silicone rubber used is 3.2 cm in diameter with 5 turns. Results of the research showed that the greater the bending is given, the greater the value of losses in optical fiber will be, the trend graphs show the value of the sensitivity of the sensor for R 2 = 0,8765, so the inferred design sensor devices made have the potential to be applied as flood sensors.
