dc.description.abstract | Sampel air limbah mengandung senyawa organik aromatik seperti fenol.
Fenol merupakan zat polutan prioritas dan berbahaya. Metode deteksi fenol secara
konvensional menggunakan alat deteksi seperti kromatografi dan spektrofotometri
tidak efektif. Alternatif deteksi fenol yakni menggunakan biosensor fenol dengan
metode voltametri siklik. Studi literatur ini bertujuan mengkaji mekanisme
tirosinase yang tepat, mengkaji optimasi pengukuran biosensor senyawa fenol
dengan biofilm P. fluorescens, mengkaji modifikasi elektrode kerja dengan
penambahan supporting material, dan mengkaji hasil kinerja analitik biosensor
fenol. Pembentukan biofilm P.fluorescens di permukaan SPCE akan
mempermudah imobilisasi enzim tirosinase. Keberhasilan imobilisasi ditandai
dengan munculnya arus reduksi dan oksidasi. Penambahan magnetit-PEG akan
meningkatkan deteksi biosensor fenol sehingga menghasilkan linearitas sebesar
0,9925 dan 0,9989. | id |
dc.description.abstract | Wastewater samples contain aromatic organic compounds such as phenol.
Phenols are the priority and harmful pollutant substances. Conventional phenol
detection methods using detection tools such as chromatography and
spectrophotometry are ineffective. An alternative to phenol detection is to use
phenol biosensors with the cyclic voltammetry method. This literature study aims
to examine the proper mechanism of tyrosinase, review the optimization of
biosensor measurements of phenol compounds with biofilm P. fluorescens, review
the modification of working electrodes with the addition of supporting materials,
and review the analytical performance results of phenol biosensors. The formation
of P.fluorescens biofilms on the surface of the SPCE will facilitate the
immobilization of the enzyme tyrosinase. The success of immobilization is
characterized by the emergence of reduction and oxidation currents. The addition
of magnetite-PEG will improve the detection of phenol biosensors resulting in the
linearity of 0,9925 and 0,9989. | id |
