Abstract
Telah dilakukan penelitian tentang perancangan sistem sensor temperatur tinggi
berbasis fiber bragg grating (FBG) dengan metode enkapsulasi. Metode
Enkapsulasi FBG menggunakan ceramic tube berbahan dasar mullite ceramic dan
Geopolymer Ceramic. Penelitian ini menggunakan efek pergeseran panjang
gelombang Bragg (λB) akibat pengaruh perubahan temperatur pada FBG. Akuisisi
data pergeseran panjang gelombang Bragg (λB) menggunakan Optical spektum
analyzer(OSA) dengan sumber cahaya dari Internal Wavelength Calibrator. Hasil
pengujian karakteristik sensor diperoleh nilai sensitifitas Bare FBG sebesar 10
pm/oC sedangkan pada sistem sensor Keramik Mullite dan sistem sensor keramik
geopolimer memiliki sensitifitas masing-masing sebesar 11 pm/oC dan 6 pm/oC.
Resolusi untuk Bare FBG diperoleh 0.1oC sedangkan pada sistem sensor Keramik
Mullite dan sistem sensor keramik geopolimer diperoleh resolusi masing-masing
sebesar 0.08oC dan 0.15oC. Metode enkapsulasi telah berhasil meningkatkan Range
pengukuran FBG dari 300oC menjadi 386oC dengan keakurasian, presisi dan
kestabilan yang tinggi.

It has done a research about system design of high-temperature sensor that based
on fiber Bragg grating (FBG) with encapsulation method. The FBG encapsulation
method uses a ceramic tube which contains mullite ceramic and Geopolymer
Ceramic. This study uses Bragg wavelength shift effect (λB) as a consequence of
the effect of temperature changes on the FBG. Data acquisition of Bragg
wavelength shift (λB) uses Optical spectrum of analyzer (OSA) with a light source
from the Internal Wavelength Calibrator. The test results of sensor characteristics
are obtained sensitivity value of Bare FBG at 10 pm /0C, while the Mullite Ceramics
sensor systems and geopolymer ceramic sensor systems have a sensitivity
respectively at 11 pm /0C and 6 pm /0C. Resolution for Bare FBG is obtained 0.1
0C, while the Mullite Ceramics sensor systems and geopolymer ceramic sensor
systems are obtained resolution respectively at 0.08 0C and 0.15 0C. Encapsulation
method has been successful to increase FBG measurement range from 300 0C to
386 0C with the accuracy, precision and high stability.
