Abstract

Bacterial cellulose (BC) can be applied in various fields such as biomedical, separation membranes, artificial blood vessels, and substrates for cartilage tissue engineering. BC still has low mechanical properties, so a bacterial cellulose composite was formed with Gardenia Leaf Extract (BC-GLE) to obtain higher mechanical properties. The purpose of this study was to determine the effect of adding a crosslinker, namely 1, 2 and 3% tapioca flour soaked with CBC-GLE to form (CBC-GLEC) by knowing the mechanical, physical, and structural properties (CBC-GLEC). BC is produced from a mixture of coconut water, sugar, and urea. BC was fermented with Acetobacter xylinum for 14 days. Composed with gardenia leaf extract and called bacterial cellulose-gardenia leaf extract composite (CBC-GLE). BC, CBC-GLE, and CBC-GLEC were characterized by testing water content, tensile strength, compressive strength, structural analysis using FTIR, and degree of crystallinity using XRD. The addition of Crosslinker can reduce the percentage of the water content of CBC-GLEC by 3% with a value of 90.73%, CBC-GLE 95.69%, and BC 99.21%. The best tensile strength test results were the addition of cross-linked starch with a concentration of 3% (CBC-GLEC) with a value of 121.45 MPa, CBC-GLE 49.81 MPa, and BC 32.09 MPa. The best compressive strength test results were the addition of starch crosslinker with a concentration of 3% (CBC-GLEC) with a value of 4.38 mm, CBC-GLE 3.42 mm, and BC 2.65 mm. The results of the FTIR spectrum showed that the functional groups contained in cellulose only experienced a shift, while the results of the analysis of the degree of crystallinity showed the percentage of the degree of crystallinity of BC was 75.47%, CBC-GLE was 94.42%, CBC-GLEC starch 3% was 67.26%.
