Abstract

Pengukuran suhu penting dilakukan di berbagai sektor dalam industri karena suhu memiliki efek signifikan pada bahan dan proses pada tingkat molekuler. Seringkali, pengukuran suhu diperlukan pada lingkungan yang sulit dijangkau oleh alat ukur karena menggunakan sensor elektrik yang dapat terinterferensi medan elektromagnetik. Oleh karena itu, pengukuran suhu memerlukan pemantauan dan pengendalian agar proses dapat bekerja dengan baik. Metode pengukuran suhu menggunakan sensor serat optik plastik struktur tapered dengan lapisan ZrSiO4 memiliki keunggulan non destruktif, sensitivitas tinggi, dan dapat mengurangi shifting pada spektrum panjang gelombag akibat suhu. Proses fabrikasi sensor dengan mentaper serat optik plastik dan lapisan dengan campuran PMMA, SDS, dan ZrSiO4. Pada pengujian karakteristik sensor dengan variasi tanpa lapisan, 0% ZrSiO4, 0,5% ZrSiO4, dan 1% ZrSiO4 didapatkan sensitivitas tertinggi sebesar 1,51 x 10-2 dBm/0C untuk lapisan 1% ZrSiO4. Semakin bertambahnya konsentrasi ZrSiO4 pada campuran lapisan mampu melidungi sensor dari suhu lingkungan, meningkatkan nilai karakteristik sensor, serta mengurangi perbedaan nilai puncak panjang gelombang akibat pengaruh perbedaan suhu. Didapatkan karakterisasi nilai puncak panjang gelombang sensor serat optik plastik struktur tapered dengan lapisan ZrSiO4 yakni pada rentang 682 - 683 nm

Temperature measurement is important in many sectors of industry as temperature has a significant effect on materials and processes at the molecular level. Often, temperature measurement is required in environments that are difficult to reach by measuring instruments because they use electrical sensors that can be interfered by electromagnetic fields. Therefore, temperature measurement requires monitoring and control for the process to work properly. The temperature measurement method using a tapered structure plastic optical fiber sensor with coating ZrSiO4 has the advantages of non-destructive, high sensitivity, and can reduce shifting in the wavelength spectrum due to temperature. Sensor fabrication process with plastic optical fiber taper and lapisan with a mixture of PMMA, SDS, and ZrSiO4 In testing the sensor characteristics with variations without coating, 0% ZrSiO4, 0,5% ZrSiO4, and 1% ZrSiO4 obtained the highest sensitivity of 1,51 x 10-2 dBm/0C for 1% ZrSiO4 coating. The increasing concentration of ZrSiO4 in the coating mixture protects the sensor from ambient temperature, increases the sensor characteristic value, and reduces the difference in the peak wavelength value due to the influence of temperature differences. The characterization of the peak wavelength value of the plastic fiber optic sensor tapered structure with ZrSiO4 coating was obtained that is, in the range of 682 - 683 nm.
