Monitoring of Noise Contour Mapping and Hearing Conservation Program of Rice Milling Workers in Griyan Karanganyar

Abstract

The use of production machines for a rice mill creates noise in the workplace, in addition to causing hearing loss and also disrupting work performance. So that the potential danger of noise at work must be controlled. The purpose of this study was to determine the noise mapping and implementation of a hearing conservation program in the Griyan Karanganyar rice mill. The research methods used in this paper is descriptive method describing research data in the form of noise map using the surfer 13 application and assessment of hearing conservation programs through the employee assessment form. The results of data collection in the thresher machine area = 110.15 dBA, in the skin crushing machine area = 109.39 dBA, in the bleaching machine area = 107.97 dBA, in the sifting area = 85.56 dBA and in the drying area = 80.53 dBA. All above Threshold Limited Value (TLV) except in the drying area. Overall stated that the Hearing Conservation Program (HCP) was declared unsuccessful from the worker's assessment of 40% agreeing and 60% disagreeing.
