## Abstract
This study aims to test of sensor based plastic optical fiber for measuring electric current and magnetic field using a macrobending technique. Sensor testing is done by using length of peel variation of with cladding and without cladding sensor type which is covered by magnetic fluid in a plastic tube. The measurement is done by putting the sensor near the magnetic field source produced by a wire coil that is electric current flowed. The magnetic field interact with the magnetic fluid that is on the sensor resulting in the refractive index of fiber optic sensor increases.This causes the power losses to increase and the light intensity transmitted from the LED to the phototransistor decreases so that the resulting of output voltage also decreases. The best results obtained on the with cladding sensor type with 3 cm length of peel for measuring electric current produce a sensitivity value of 0.008 V/A and a resolution of 0.121 A, while for measuring magnetic field produce a sensitivity value of 0.738 V/T and a resolution of 1.345 T. Testing of sensor based on plastic optical fiber suitable for measuring electric current and magnetic field with advantages such as having high sensitivity, easy fabrication, low cost, real time, as well as has a simple measurement and accurate system.
