ABSTRAK

Telah dilakukan penelitian tentang pengaruh tekanan terhadap pergeseran pada fiber sensor cross section ellips. Prinsip kerja dari penelitian ini adalah memanfaatkan penurunan transmitansi akibat dari loss pada fiber optik. Pengujian dilakukan dengan alat mikropositioner. Dari penelitian ini diperoleh data berupa nilai transmitansi sebagai fungsi pergeseran fiber sensor. Hasil dari penelitian ini didapatkan ketelitian sebesar 97,97% untuk fiber sensor cross section lingkaran dan ketelitian sebesar 98,99% untuk fiber sensor cross section ellips.

ABSTRACT

A research has been done about the effect of pressure on shift in cross section ellips fiber sensor. The principle of this research is to take advantage of the decrease of transmittance resulting from loss in fiber optic. Testing is done by micropositioner tool. This research obtained data in the form of the value of transmittance as a function of the sensor fiber shift. The results of this study obtained accuracy of 97.97% for fiber cross section circle sensor and accuracy of 98.99% for fiber sensor cross section ellips.

Keywords: fiber sensor, ellips, pressure, transmittance, loss
