This research aims to analyze the performance of metakaolin based on geopolymer ceramic for a fiber optics temperature sensor design. The fiber optics used in this research is single mode type Fiber Bragg Grating (FBG). The geopolymer ceramic synthesis was using metakaolin via alkali activation method (NaOH + NaO.3SiO2 + H2O). Chemical composition, crystallinity and morphology of geopolymer ceramic was characterized using Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). Sensor characteristics measurement results show that the sensitivity of the sensor is 8,6 pm °C-1 with the linearity of 99.73% and have a high stability of measurement.
