<p>Peneltian ini bertujuan menganalisis spektrum Fourier Transform Infra Red (FTIR) dan menentukan minimum loss dari kaca Tellurite-Bismuth-Zinc-Plumbum (TBZP) yang dipengaruhi oleh variasi (PbO). Kaca TBZP difabrikasi dengan teknik melt quenching dengan komposisi 55TeO2-2Bi2O3-[43-x]ZnO-xPbO (%mol) dengan x=2, 3, 4, 5. Hasil uji spektrum Fourier Transform Infra Red (FTIR) menunjukkan pita absorbsi terbesar berada pada panjang gelombang lebih dari 620nm. Absorbansi tersebut lebih diakibatkan oleh adanya transisi vibrasi pada daerah infrared. Minimum loss pada kaca TBZP diprediksikan secara teoritis melalui fitting data infrared edge dengan kurva Rayleigh scattering. Minimum loss kaca TBZP sebasar 2,94 dB/km hingga 2,35 dB/km pada λ=5534,2nm hingga 5821,2nm. Nilai minimum loss menurun seiring pertambahan konsentrasi ion Pb2+ dalam kaca TBZP. Sifat tersebut menjadikan kaca ini sebagai kandidat yang baik untuk aplikasi yang menggunakan gelombang infrared seperti fiber optik infrared.</p><p> </p><p>The aims of this research were to analyze the spectrum of Fourier Transform Infra Red (FTIR) and determine the minimum loss of Tellurite-Bismuth-Zinc-Plumbum (TBZP) based glass which affected by the variation of (PbO). The TBZP glass has been fabricated by melt quenching technique with composition 55TeO2-2Bi2O3-[43-x]ZnO-xPbO (mol%) with x=2, 3, 4, 5. Fourier Transform Infra Red (FTIR) spectra test results showed that the greatest absorption bands were at wavelengths over 620nm. Vibrational transition has the reason behind the absorbance in the infrared region. Minimum loss on glass TBZP theoretically was predicted by fitted data from the infrared edge and rayleigh scattering curve. The minimum loss of TBZP was of the range 2,94 dB/km to 2,35 dB/km at λ=5534,2nm to 5821,2nm. The minimum loss of TBZP glass decreases as the Pb2+ content in glass increases. This makes these glasses are good candidate for IR-application such as infrared optical fiber.</p>
