Abstract

Analysis of noise and mechanical vibration was conducted using combine harvester machine Yanmar AW 70V. The purpose of this research was to analyze of the noise and mechanical vibration combine harvester machine Yanmar AW 70V. This research was conducted at Agriculture Land of Mulya Sari Village, Tanjung Lago Disticts, Banyuasin District, Sumatera Selatan Province on May to July 2017. This research was done using the experimental method. The noise was measured by using the grid method and sound level meter. Vibration was measured at some points in combine harvester machine Yanmar AW 70V using a vibration meter. The observed parameters were the noise and vibration. The intensity was described in mapping using “Software Surfer 11”, which generates the contour of noise. The measured vibration data was described in form of graphs. Based on the results at combine harvester machine Yanmar AW 70V, the highest intensity of noise was at operator position on the image contour of noise 92.9 dB with the motor rotation speed of 2800 rpm, whereas the lowest noise intensity 74.4 dB with the motor rotation speed of 1000 rpm. The highest intensity of noise from combine harvester machine Yanmar AW 70V of 97.2 dB with the motor rotation speed of 2800 rpm, whereas the lowest noise intensity of 61.2 Db with the motor rotation speed of 1000 rpm. Based on the result, highest level of vibration was found at the steering lever of 13.2 m/s2 with the motor rotation speed of 2800 rpm and lowest level of vibration was found at the frame of rollers of 0.4 m/s2 with the motor rotation speed of 1000 rpm.
