Abstract

The purpose of this research was to analysis of noise, workload and mechanical vibration on rice milling machines. This study was conducted on August to December 2017 at Lubuk Empelas and Muara Lawai Villages, Muara Enim District, South Sumatera Province. This research was done by using the descriptif method. The noise was measured by using the grid method and sound level meter. Vibration was measured at some points on rice milling machine using vibration meter. Workload measurements are performed when the operator works by using the Heart Rate Monitor tool. The observed parameters were the noise, workload and vibration. The level of noise was described in mapping by using “Software Surfer 11”, which generates the contour of noise. The measured workload and measured vibration data were described in form of tabel and graphs. Based on the results of rice milling, the highest level of noise was at operator position on the image contour of noise 102.8 dB with engine rotation of 1,500 rpm at height of 80 cm on the first floor in the first plant. Based on the results on rice milling machines, the highest level of noise was at operator position on the image contour of noise 98.3 dB with engine rotation of 1,400 rpm at height of 80 cm on the first floor in the second plant. Whereas the lowest level of noise of 87.2 dB with the engine rotation of 1,500 rpm at height of 140 cm on the first floor of first plant. Whereas the lowest level of noise of 87.1 dB with the engine rotation of 1,400 rpm at height of 140 cm on the first floor of first plant. Based on the results obtained the value of % CVL in the first and second rice mill was still below 30 % which means the operator has a light workload with an average work time of 3 to 4 hours per day. Based on the result, highest level of vibration was found at the engine floor of 1.9 m/s2 with the engine rotation of 1,500 rpm at the first plant. The highest level of vibration was found at the engine floor of 2.5 m/s2 with the engine rotation of 1,400 rpm at the first plant, and lowest level of vibration was found at the lower operator floor and the top operator floor of 0.4 m/s2 at the first plant and lowest level of vibration was found on the top operator floor was 0.3 m/s2.
