Abstract
Determination of the characteristics of the pH sensor using U-shaped optical fiber was carried out with various varieties, namely length without a coat, indentation diameter, and the number of imperfections. Optical fiber as a light transmission medium is used as a sensor to detect the pH level of the solution. The sensor output is read on the OPM in the form of output power. The best characteristic of the pH sensor was obtained in the number of imperfections, namely number of imperfections 3 with a value range of 32.0 µW, a sensitivity of 3.2 µW/pH, and a resolution of 0.3 x 10-3 pH. The greater the power losses in the optical fiber sensor, the better the sensor characteristics. Determination of the characteristics of the pH sensor is very suitable to be carried out using U-shaped optical fiber in simple measurements and easy fabrication
