This article discusses about the press machine posture movement effectiveness for cassava chips mold. This research
was conducted at Karya Lestari Jaya which is one of the SMES in Tulungagung, East Java, Indonesia. The
industry is in trouble with new manual press machine that is too rigid and heavy to handle. The operator complain
of pain the arm and forearm. this means the activity has deficient posture when the operator works. This study aims
to know the ergonomics risk factors for press machine and determine the best recommendation by the operator and
owner SMEs Karya Lestari Jaya suggestion. We conduct a case study by collect the data from observation. We analyze
the observation data by RULA (Rapid Upper Limb Assessment). Then, we do interview of eight resource person
to get the attribute that required to upgrade the machine. Besides that, we analyze the best recommendation by AHP
(Analytic Hierarchy Process). This research result a value of RULA 6 which means the attitude in pressing the dough
or working facilities need to repair immediately. There are five phases to determine design there are information
phase, creative phase, analyze phase, development phase and recommendation phase and the result of AHP show
that the best recommendation is the addition of a pneumatic system in machine press to lighten the lever. In the end,
this research can be useful to the company by knowing body posture and evaluating the upgrade machine.
We would like to gratitude to DIKTI Research and Technology
Ministry to grant funding for this research project.
We also say Many Thanks to all academics and administration
staff at Universitas Widyagama Malang for support
such as Research Laboratory.
