PROSES HIDROLISA PATI TALAS SENTE (ALOCASIA MACRORRHIZA) MENJADI GLUKOSA : STUDI KINETIKA REAKSI
ABSTRACT: Starch hydrolysis
process is the method used in the conversion of starch to glucose from starch
material such as Giant Taro (Alocasia Macrorrhiza) using acid catalyst. In this
study starch hydrolysis of Giant Taro using hydrochloric acid catalyst is
divided into three stages of continuous process that aims to obtain a good pH
and temperature on starch hydrolysis process of Giant Taro and studying the
kinetics process of starch hydrolysis of Giant Taro into glucose. The
experiments were performed using a fixed variable, namely particle size of
starch 20 mesh, the ratio of raw material to water is 1:30 (g starch / ml of
water), stirring speed 200 rpm and reaction time 60 minutes.There are two
random variables i.e. pH 2, 3, 4, 5 and temperature of reaction 500C, 600C,
700C, 800C, 900C. Results of hydrolysis were analyzed using the DNS method to
determine glucose levels. The result showed good pH at pH 4 and temperature at
900C, the reaction rate constant k is 9,139x10-4/min and reaction rate equation
of hydrolysis is CA = 0,03740164. e- 0,0009139. t.
