Abstract

Humans arms was the biggest part that always exposed to the vibrations. This was because, most equipment that humans conduct while working using hand and arms. Hand- arm vibration (HAV) is vibration that transmitted while working to the workers hand and arms. The vibrations usually come from operating hand-held power tools such as jigsaw, drilling machine or grinding machine. From fifteen experiments that has been conducted, vibration that transmitted to hand were detected by using accelerometer and the signal was evaluated using signal analyser before recorded in laptop. The result obtained in the form of graph was being analyzed and interpreted. To obtain the level of vibration absorbed, the graph is calculated by using vibration reduction index. From data collected, it can be seen that the level of vibration was increasing as the speed of the jig saw increases. This is caused by the friction force between the blade and the wood producing vibration. The results obtain in the form of graph after being analyzed using signal analyzer. There are four types of gloves that has been fabricated successfully. From the analysis and observation, the result shows the effectiveness of coconut fiber in reducing the level of vibration. This was proof from calculation that has been made by using vibration reduction index (VRI).
