The purpose of this research is to study possibility of applying of
Science, Technology and Society (STS) approach based on laboratory experiment
in Second Basic Chemistry Experimental on subject matter of the redox reactions
and electrochemical. The Laboratory experiment that was studied in this research
is decreasing of cationic dye Basic Fuchsin concentration with
electrodecoloritation method.
This research uses literature review supported by laboratory experimental
data. The parameter of this research are the experimental procedures, the
availability of experimental materials, the time of experiment, the data analysis
and the availability of analytical instruments.
The conclution of this research is the experimental of decreasing of
cationic dye Basic Fuchsin concentration with electrodecolorisation method can
be applied for Second Basic Chemistry Experimental on subject matter of the
redox reactions and electrochemical because it was a simple experimental
procedure, the experimental materials are cheap and easily obtained, experiment
time is shorter, easy data analysis and the adequacy of availability of instruments
in the laboratory analysis in the laboratory of Chemical Education Department,
Teacher Training And Education Faculty, Sebelas Maret University.
