Abstract

This study aims to 1) determine the effect of comparison between brem dregs flour with a
solution of hydrochloric acid (HCl) and a long hydrolysis of the characteristics of liquid sugar
produced, 2) determining the ratio of brem dregs flour with a solution of hydrochloric acid (HCl) and
long hydrolysis to produce the characteristic of best sugar liquid.
This experiment was factorial experiment using a randomized block design (RAK) with two
factors. The first factor is the ratio between Brem dregs flour with a solution of hydrochloric acid
(HCl) 0,75% consists of three levels, namely; 1:4, 1:6 and 1:8. The second factor is the length of
hydrolysis which consists of three levels ie; 10 minutes, 20 minutes and 30 minutes. Thus obtained 9
treatment combinations were grouped into two, based on the execution time so that obtained 18
experimental units. The variables analyzed were the starch content, ash content, reducing sugar, yield
and total dissolved solids. Objective data were analyzed by analysis of variance followed by Duncan
test.
The results showed that the brem dregs flour with a solution of hydrochloric acid (HCl) and a
long hydrolysis significant  effect on the starch content, reducing sugar, yield and total dissolved
solids, while the ash content not significant. Interactions between treatment comparisons brem dregs
flour with a solution of hydrochloric acid (HCl) and a long hydrolysis very significant effect on the
starch content, reducing sugar, yield and total dissolved solids. Handling of comparison among brem
dregs flour with a solution of hydrochloric acid (HCl) 1:4 and hydrolysis for 30 minutes will produce
liquid sugar product with the best  quality in accordance with SNI 01-2891-1992 about liquid sugar
syrup composition based on the value of reduction sugar namely ash content <1% in accordance with
the SNI, reduction sugar 33,89 mg/l, yield 167,77% and total dissolved solids 49% brix except  the
starch content of 1,20%.
