Abstract:
Today, chitosan have become the attraction to among the researchers as important
source to produce the voltage. The main purpose of this project is to study the
preliminary of Hall Effect for the thin film system. The thin film consists of salicylic
acid was prepared. The value of concentration of salicylic acid was varied from 0
wt.% to 50 wt.%. Another sample containing chitosan and varied salt concentration
plus 1 molar of MnCh also have been prepared. This experiment involved the
instrument like Electrochemical Impedance Spectroscopy (EIS), Scanning Electron
Microscope (SEM), Four Point Probes (FPP) and Hall Measurement System. The
value of resistivity, magnetic field and conductivity was determined in order to assure
the Hall Effect value can be calculated. From the EIS measurement, the value of
conductivity in range 9.24 x 10-4 to 1.82 x 10-6 (Omr1• From the FPP measurement
that was obtained in the range of 6.97 x 10-3 to 5.79 x 10-6. From SEM measurement
thickness was obtained in the range 32.35µm to 42.40µm. By applying the value of
thickness from SEM measurement, the value of estimation of hall voltage can be
calculated.
