Abstract
Natural fiber reinforced composites are widely applied to equipment with materials that have a combination of two basic properties, namely strength and lightness. Different fibers will produce materials with different qualities. This study aims to determine the optimum ability of kenaf stem fiber and tobacco stem fiber which contain relatively high cellulose to be used as soundproofing materials and also to utilize tobacco stems which were originally considered as agricultural waste to become a more useful raw material. Cellulose in plant fibers is often used as a soundproofing material. Examples of plant fibers that are used as soundproofing materials are coconut plant fibers and also wood. Soundproofing material can reduce the risk of noise causing hearing loss. In this study, the main ingredients were epoxy resin and kenaf plant fiber and tobacco stem fiber to be used as a composite exhaust. The first step is to provide epoxy resin and kenaf stem fiber and tobacco stem fiber according to the dosage required, namely the ratio of the ratio of kenaf plant fiber to tobacco stem fiber 100:0, 60:40, 50:50, 40:60, and 0:100. Then prepare the mold to be able to form a composite exhaust. Then prepare a noise meter or sound level meter to measure the amount of sound produced by the composite exhaust. From the research results obtained, the composite exhaust produces the smallest sound, namely 81.6 dBA at a fiber ratio variation of 60:40 at 1500 RPM and produces the biggest sound, namely 99.1 dBA at a fiber ratio variation of 0:100 at RPM 3500. Results It can be said that the damping on the composite exhaust is quite good because it is not too far from the quality standard threshold, which is 83 dBA. The combination of the two fibers in the composite exhaust in this study was quite influential in reducing noise compared to those not using a combination of the two fibers. The bility of kenaf stem fiber to reduce noise is better than that of tobacco stem fiber because the cellulose content in kenaf stem fiber (by 50%) is higher than that of tobacco stem fiber (by 37%).
