Abstract
Alkaloids from Solanum xanthocarpum stem were successfully extracted. Extracted
alkaloids were characterized by qualitative chemical tests and spectroscopic
measurements. The effectiveness of the inhibitor was determined by weight loss and
electrochemical measurement methods. From the weight loss measurement, maximum
inhibition efficiency of 93.14% was achieved. The temperature effect study reveals
that the inhibitor can work up to a temperature of 58 C. Electrochemical
measurement reveals that alkaloids could inhibit effectively up to 98.14% and serve
as a mixed type of inhibitor. A study on kinetic parameters reflects that the inhibitor
forms a potential barrier to protecting the MS. The values obtained from the
thermodynamic parameters study reflect that the process is a spontaneous
endothermic process.
