Abstract
This research aims to analyze the effects of composite composition of epoxy resin, banana stem frond, and coconut coir powder on the tensile strength and impact strength of composites produced. This research method used the hand lay-up method. The fiber was treated without alkalization or 5% alkalization for 2 hours. The tensile test specimens were formed according to ASTM D638M, standard, and the bending test specimens followed ASTM E23. From the impact test treatment, the highest results were obtained in composites with a composition of 30%: 35%: 35% with an impact value of 0.0125 N/mm2 and the lowest results were composites with a coposition of 70%: 15%: 15% with a value of 0.0052 N/mm2. At the tensile test, the most optimal tensile strength occured at a composition of 30%: 35%: 35% which is equal to 0.17N/mm2, while the lowest was composite with a composition of 70%: 15%: 15% which was equal to 0,06 N/mm2.
