PERBAIKAN FASILITAS PEMINDAHAN BAG PAKAN UDANG DI DEPARTEMEN PACKAGING GUNA MENGURANGI RESIKO CEDERA TULANG BELAKANG
Abstract: Manual Materials
Handling (MMH) activities still widely used in a job. This is because in this
activity has a high flexibility, inexpensive, and easy to apply. However, these
activities also constitute a risk when applied to the inadequate environment, less support of tool, and bad
posture of work. Therefore, measurement of safety limit in doing the job by
using a calculation based on the equation of NIOSH Lifting Index. The case
study at PT. Central protein Prima Surabaya is the removal of shrimp feed bag
that still use manual way. Acquisition of STRWL calculation results obtained
for the removal of shrimp feed bag stacks 1, 2, 3, 4, 5, 6, and 7 from 5,003 Kg
to 67,41 Kg. Actual load which worker must lifted in this case study on a pile
of 1 to 7 is 25 kg. Load is lifted for
the removal of shrimp feed bag bigger than STRWLmake it not feasible. CLI
obtained in shrimp feed bag removal activity is 6.041 which value exceeds 3.
Therefore CLI in this case study may create a risk of spinal cord injuries and
to do their job changes. By measuring the changes in safety limits and do the
work, expected reduced risk of injury to workers. After measuring the safe
limit for the removal of bag obtained load is lifted workers have the risk of
spinal injury, so it is given recommendations for improvement is by doing a
redesign on a conveyor in the form of additional elevation (vertical) 57 cm at
the end of the conveyor, as well as shortening the horizontal distance between
the worker's body with a bag of shrimp feed time of transfer. With these
recommendations obtained a decrease CLI becomes 1.795, which means that the
risk of injury is between 1 <CLI ≤ 3 and can be reduced.
