Hydrolysisof starch is one of the methods to make glucose. Starch can be
obtained from banana. The hydrolysis can be catalyzed by an acid or an enzyme.The
objective of the research was to seek tne effect ot tne aCId concentration on tne
hydroiysisof bananastarchat 100 "C of temperatureand atmosphericpressure.Theexperiment was carried out in a stirred reactor equipped with condensor. The hydrolysis
were pseudo first order with respect to starch concentration. Increasing acid
concentration caused the rate constant of hydrolysis increases. The rate constant of
starch hydrolysis is related to the acid concentration by: k' = O.O83067e..o,0327[H+]
This equation is valid for temperature 100 "C and HCI concentration 0,05N - 0,3 N
