Manual material handling ha
s
a high risk of injury such as low back pain. PT. ABO
FARM is a company engaged in the field of agriculture, particularly in the export
of beans. One of the export process is the process of transporting beans from the
workstations collector
to
the
warehous
e
in PT. ABO FARM. Observation results
showed that the removal of material in the process of loading is taking, carrying
and putting sacks of beans into a pick
up truck on a workstation collection is done
manually and not ergonomic. Material is removed in
the form of sacks of beans
with an average weight of 55 kg.
This research aims to design a method for manual material handling in the loading
process become more ergonomic. The approachs taken in this research are a
biomechanical approach and a lifting eq
uations recommended by NIOSH agencies
working in the facility design. The design method of manual material handling is
done by making suggestions for grip position on the proposed container and
perform testing of several alternative methods of manual mater
ial handling with
parameters generated compressive force on L5/S1.
The results of tests on several alternative methods of generating manual material
handling is more ergonomic. It is shown by the reduced L5/S1 compressive force
against each activity in th
e process of loading are
taking activity decreased about
98
% from
12168 N
becomes
276.2 N
. In carrying activity
, compressive force
decreased about
97% from 9213 N becomes 275.2
N. And for putting activi
ty
decreased about
96
% from 7109 N becomes
280
N.
