Pengaruh Konsentrasi Natrium Hidroksida terhadap Karakteristik Selulosa Mikrobia dari SCOBY
Abstract
Microbial cellulose is cellulose produced from a fermentation process involving bacteria and yeast, which has excellent potential as an alternative raw material to replace synthetic fibers. This research aims to determine the effect of NaOH on the characteristics of microbial cellulose and determine the concentration of NaOH that produces the best characteristics of microbial cellulose. This research used a randomized block design with varying treatment concentrations of NaOH consisting of 6 levels, namely (0%, 5%, 10%, 15%, 20%, and 25% w/v). Each treatment was grouped into three based on the microbial cellulose production time, so 18 experimental units were obtained. The variables observed were thickness, tensile strength, elongation at break, elasticity, and thickness expansion. The data obtained was analyzed for diversity and continued with the Least Significant Difference Test. The research results showed that the concentration of NaOH significantly affected the tensile strength, elongation at break, elasticity and swelling but had no significant effect on the thickness of microbial cellulose. NaOH concentration of 15% (w/v) produces the best characteristics of microbial cellulose with a tensile strength value of 39.63 ± 1.33 MPa; elongation at break is 6.43 ± 0.35%; elasticity is 607.98 ± 26.26 Mpa and thickness expansion is 126.19 ± 2.06%.
