To reduce the physical workload in this study will be determined the length of rest time using the Indirect Assessment Method with categories of physical (physiological) workload, pulse (beats / minutes), classification% CVL (Cardiovasculair Load), calculating energy consumption, and calculate the need for rest. The study was conducted at rest at 09.30 and at 15.00 WIB. Pulse measurements are carried out using the 10 Pulse Method which then affects the amount of energy consumption. Based on the research results, it is known that at the Plenner machine work station, the Jointer and Telthing machines are in the classification of% CVL, the workload is due to the level of 30% -60%.
