Abstract
Sensor suhu berbasis serat optik berstruktur singlemode-multimode-singlemode (SMS) telah banyak dikembangkan dalam berbagai aplikasi. Pengukuran suhu menjadi salah satu aplikasi penting dari sensor serat optik karena sensor elektrik tidak dapat digunakan pada tempat yang terpengaruh interferensi elektromagnetik. Pada penelitian ini dirancang sebuah sensor suhu menggunakan material ZrSiO4 sebagai coating untuk meningkatkan sensitivitas sensor. ZrSiO4 memiliki nilai konduktivitas panas yang rendah, koefisien ekspansi termal yang rendah, juga tahan terhadap panas yang tinggi sehingga dipilih sebagai material coating sensor suhu serat optik SMS. Pengaruh pemberian coating terhadap karakteristik sensor dianalisis menggunakan metode intensitias dan spektrum transmisi yang diukur pada rentang 25-60 °C dengan kenaikan setiap 5 °C. Hasil pengujian diperoleh sensitivitas tertinggi sebesar 0,011238095 dBm/°C untuk sensor dengan coating 1%, 8,8 kali kali lebih tinggi dibandingkan dengan sensor tanpa coating. Pengujian spektrum trasmisi menggunakan Optical Spectrum Analyzer (OSA) diperoleh nilai puncak panjang gelombang bervariasi pada setiap sensor. Pengaruh ZrSiO4 terhadap karakteristik sensor mampu meningkatkan sensitivitas sensor dan mengurangi perbedaan nilai puncak panjang gelombang akibat pengaruh perubahan suhu. Hasil pengujian membuktikan adanya pergeseran spektrum panjang gelombang baik bernilai positif akibat perubahan suhu atau bernilai negatif akibat penambahan material coating.

Singlemode-multimode-singlemode (SMS) structured optical fiber-based temperature sensors have been widely developed in various applications. Temperature measurement is one of the important applications of fiber optic sensors because electrical sensors cannot be used in places affected by electromagnetic interference. In this study, a temperature sensor was designed using ZrSiO4 material as a coating to increase the sensitivity of the sensor. ZrSiO4 has a low heat conductivity value, low thermal expansion coefficient, and is also resistant to high heat so it was chosen as the coating material for the SMS fiber optic temperature sensor. The effect of coating on sensor characteristics was analyzed using the intensity and transmission spectrum method measured in the range of 25-60 °C with an increase of every 5 °C. The test results obtained the highest sensitivity of 0,011238095 dBm / ° C for sensors with 1% coating, 8.8 times greater than the sensor without coating. Trasmission spectrum testing using Optical Spectrum Analyzer (OSA) obtained peak wavelength values vary in each sensor. The effect of ZrSiO4 on sensor characteristics can increase sensor sensitivity and reduce the difference in peak wavelength values due to temperature changes. The experiment proves that there is a shift in the wavelength spectrum, either positive due to changes in temperature or negative due to the addition of coating material.
