Abstract


This research is carried out in order to evaluate the working postures of seven workers with
different job categories at a garden maintenance service. These seven categories of works are
divided into 23 work elements. The aim of this research is to investigate the presence of work-
related pain symptoms, find all risk related to poor working postures, and finally propose sets of
recommendations for improvement of working methods. Nordic Body Map questionnaire is used
in the study to detect the occurrences of workrelated pain. Meanwhile, risk level assessment for
working postures was carried out by means of Rapid Entire Body Assessment (REBA) method.
All the two applied on seven job categories of workers.
The results showed that all workers observed experienced with pain symptoms both after and be
fore carry out the work. According to REBA analysis, there are 82.6% medium level risk workin
g elements, 10.9% high level risk, 4.3% very high level risk, and 2.2% low level risk. Recommen
dation for improvement of working posture was given for work element, namely fertilizer sowing
(very high level risk), hedge trimming (high level risk), and pesticide spraying (high level risk).
Implementation of these proposed improvements result on diminishing the frequency of occurren
ce and the level of risk on physical pain.
