The calculation of exposure level by the method of QEC show in Table 3. Table 3 show that some job positions
could potentially lead to work-related musculoskeletal disorders (WMSDs) in workers. Two jobs that need
immediate improvement are stirring material and put the material into a bucket for the manufacture of ring wells,
with the exposure level of 73.8% and 71.5%. While another activities requiring immediate repair / in the near future
with the exposure level of 54.5% - 67%, and some other elements need of repair activities in the future with the
exposure level of 41.9% - 49.3%. QEC analysis show that manufacturing bricks and ring wells with current
working methods can cause WMSDs so that required working method improvement and equipped by some working
tools such as stirring cement, brick molding and brick working table. The result of this design is expected to increase
the productivity of workers as well as the achievement of an ergonomic system of work as can be seen in Figures 4,
5 and Figure 6.
