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.
