| dc.description.abstract | Finishing process of workmanship on jewel
stone at small scale industry of jewelry crafting in
Subagan village Karangasem was polishing. This
process was done manually by working posture were
cross-legged sitting on the floor. This awkward
working posture (cross-legged sitting) caused
increase workload. High work load can decrease
production and productivity. To solve these problems,
increase productivity and income of craftsmen, the
improvement effort should done by design of jewel
stone sharpener in order to could be able to use as
polishing tools of jewelry and then improve according
to ergonomics approach. The research was conducted
on 16 jewel craftsmen by "treatment by subject
design" and three treatments methods. Work load was
measured by using work heart rate which was count
using ten pulses methods. Work productivity was
assessed by amount of product per pulse rate. The
data were analysed by using t pired test at significant
level 5%. Results were showed as follows: significant
of difference (p < 0.05) of work load, subjective
disorders, and work productivity between control (T0)
and treatments (T1). The average of work load on T0
and T1 were 104.29 ± 4.65 beats/minute and 88.64 ±
2.33 beats/minute or decreased 15.0%. And then the
average of work productivity on T0 and T1 were
0.01002 ± 0.00042 and 0.05801 ± 0.00207 or
increased 478,9%. Its can be concluded that T1 give
larger decreased of work load and give larger
increased of productivity compared with T0. That is
why, it was recommended the design of jewel stone
sharpener should be used by workmanship in
polishing the jewel stone and ergonomics work
