Abstract

Bran rice is a by-product of rice milling that is often utilized by the
community as animal feed. In rice, the nutrient essential that is required body is
found in the bran or rice bran. Rice bran oil has antioxidants that relatively high
which can be used as the oil for food (edible oil), Health, cosmetic, and
pharmaceutical industries. The purpose of this study is to determine the effect of
the volume of the acetone solvent, and extraction time. In the manufacture of rice
bran oil, to determine the effect of volume of solvent and time using several
variables. The variable of the volume of the solvent was 300 mL, 400 mL, 500 mL,
600 mL, and 700 mL while for the extraction time is 1 h, 2 h, 3 h, 4 h, and 5 h. The
results of this study show that the volume of solvent and extraction time on the
extraction process affect the yield and free fatty acids. On the volume of the solvent
has the highest point, namely 400 mL of 14.54%, while the average volume of the
solvent is low 300 mL of 8.25% and extraction time had the highest point i.e. 3
hours by 16,18%, while the time is low on average 1 hours of9.205%. The results
obtained for the quality of the oil not meet the standard (SNI) 061 0-1989-A because
there has been no process of preserving.
