Ergonomic Analysis Level of Noise and Vibration of Peanut Peeler Machine to Operator Safety

Abstract

Peanut peeler machine will be very helpful for workers/farmers to do the continuous processing for their yields, but this tool has a weakness that is have noise and vibration. The purpose of the research is 1). To know the noise machine level; 2). To know the mechanical vibration of machine; and 3). To know the operator safety. This research used experimental method which consist of three treatments that’s is P1 = 800 rpm, P2 = 1000 rpm, and P3 = 1200 rpm. The parameters collect is noise level, mechanical vibration, work capacity, yield, residue, and efficiency. Based on the results of research and data analysis, peanut peeler machine at 1200 rpm (P3) is 69.8 dB better than P1 800 rpm treatment that is 75.8 dB and P2 1000 rpm about 72.8 dB. it show that the sound less then 85dB (A) with a maximum operation 8 hours/day. Mechanical vibration of peanut peeler at 1200 rpm (P3) is 11,4 Hz better than P1 800 rpm treatment that is 13,3 Hz and P2 1000 rpm is 12,4 Hz. The safety level of peanut machine operators is in the low category, the actual means can work so that it can cause inconvenience operators with mechanical categories and vibrations issued. This is due to mechanical vibration machines.
