Noise is a problem that is often encountered many industrial workers today. The cement plant has production machines with high noise level. The noisy environment will arise risks on workers. The purpose of this study was to determined noise level and its effect on workers in a cement plant. The noise intensity was measured at three area of the plants; raw mill, cement mill, and sillo raw mix. There were 23 measuring points where considered as hazardous potential to workers. The measurement was carried out seven times during three days on each area. To found effects of noise exposure on workers by questionnaires. It used to found existing of physiological, psychological, and communication disturbs. The results indicated that all measured points exceeded the threshold limit value 85 dBA for 8 working hours. Raw mill and sillo raw mix have the highest equivalent noise level where each area reached 118,1 dBA and 119 dBA. The highest annoyance based on workers response was communication disturbs. Recommendations for reducting this negative effects had given technically, administratively, and control noise at receiver.
