Abstract
The rubber tapping is a monotonous task involving cyclic operations by making incisions on more than 300 rubber trees every day. PERA is a body posture analysis tool to evaluate short cyclic work. Thus, this analysis tool is suitable to evaluate the rubber tapping process. The cyclic work involved in the rubber tapping can be divided into four tasks such as (i) Removal of latex cover from the channel, (ii) Incision on the channel (iii) Adjusting the collection cup and (iv) Moving to the next rubber tree. A sample of ten rubber tappers has been selected for this study. Direct observation and video-based analysis of the body posture using PERA tool are adopted in this study. The overall PERA score of 8 or more for the work cycle, which is corresponding to a level of ‘high risk’. Therefore, the body postures resulted by the tapping work are not acceptable and corrective actions are necessary. The analysis also reveals that the second task has been reported with the major score in the rubber tapping process. Hence preventative measures are to be suggested in order to prevent bad working.
