## Abstract
Measurement of sucrose and fructose content using a plastic optical fiber sensor in spiral configuration with outside diameter and imperfection variation has been developed. The length of the optical fiber sensor used is 18 cm and the peel length of the cladding is 10 cm. The measurement conducted by dipping the sensor into a solution of sucrose and fructose at different concentrations. Both ends of the sensor are connected by LED and Phototransistor. The LED light will propagate through the POF and it is received by the phototransistor. The propagating light will be interference due to an increase in the concentration of sucrose and fructose around the sensor, so that the output voltage will be affected. The output voltage will be forwarded to Arduino Uno and read by the computer. The best characteristics of sensor are shown in the spiral configuration with imperfection variation. The best sensitivity and resolution values for sukroasa measurement are 0.141 V/% and 0.007%, while for fructose the best sensitivity and resolution values are 0.0160 V/% and 0.062%. Sucrose and fructose content sensors using plastic optical fibers have the advantages of high sensitivity, simple measurement system, easy fabrication, low cost.
