Abstract
MCC was synthesized from alpha-cellulose from microwave pretreated OPEFB. This study aims to determine the effect of microwave pre-treatment on changes in the cellulose and lignin content of OPEFB fibers and to synthesize MCC from OPEFB alpha-cellulose pretreated with microwaves. The method used in this research is exploration with 4 hydrolysis time treatments (10, 20, 30 and 40 minutes) with 3 replications. The data analysis technique used is descriptive statistical analysis. From the results of the study obtained differences in the levels of cellulose and lignin of EFB fiber before and after microwave pre-treatment. OPEFB fiber that has been pretreated has a higher cellulose content and lower lignin content than without pre-treatment. The yield and brightness level of the synthesized MCC color were different in each treatment. MCC obtained from the hydrolysis of alpha-cellulose for 10 minutes using 45% H2SO4 had the highest yield of 31.22% and the brightest color. Meanwhile, the lowest MCC yield was found in the hydrolysis treatment of alpha-cellulose for 40 minutes, namely 25.37% with a low brightness level. Furthermore, the color and texture of the MCC obtained from the best treatment was the same as that of the commercial Avicel MCC.
