<![CDATA[ABSTRACT 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. Contribute a better translation 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. Key Words : Science, Technology and Society (STS) approach, electrochemical redox reactions, electrodecoloritation method.]]>
