Abstract

The research to be carried out is how the effect of chemical treatment on banana stem fibers, if soaked in K2CO3 solution, with variants of soaking time 1, 3, 5, 7, 9 hours before analyzing banana stem fiber composite materials, and the test method used is the tensile method. The objectives to be achieved through this study are to analyze the tensile strength of areca nut fiber-reinforced composite materials after mixing with K2CO3 chemical solutions and to determine the right chemical treatment time for the characterization of banana stem fiber-reinforced composites and make banana stem fiber-reinforced composite materials or materials according to ASTM D638 Type 1 standards. The results of the tensile test of banana fiber composites showed that the final tensile strength of composites treated with alkaline K2CO3 (2%) increased compared to untreated composites. Composites with K2CO3 concentration treatment 2% with an immersion period of 9 hours have the highest tensile strength at 37.92 MPa and also the highest modulus of elasticity at 15.29 Gpa. Macro photo results showed that untreated composites had many pull-out fibers compared to composites treated with base concentrations. The alkaline concentration of K2CO3 strengthens the interface bond between the matrix and the fibers. Keywords : banana stem fiber, K2CO3 solution, tensile strength, macro photo
