Abstract—Handle on the container used in industry has an important role to reduce injuries while doing the activity manual materials handling (MMH). handle design in most industries in Indonesia is usually located on top or no handle. Therefore, this study is conducted to determine the handle position on the box. The method used is the design of experiment (DOE) based on psychophysical and physiological criteria for male workers. A psychophysical criterion refers to the borg scale for rating perceived exertion (RPE), whereas the physiological criterion refers to the heart rate. RPE and heart rate is a dependent variable, while the independent variables used were four box sizes, nine handling positions, and three handle positions on the box. Ten subjects from industrial workers performed 27 combinations for one day during four day. The results of this study indicate that a significant factor influencing psychophysical criteria are 3 main effects, while the physiological criteria just 2 main effects, handle position and box size; based on psychophysical criteria, the handle position on top has a higher RPE values than other positions; and based on physiological criteria, the handle position on top produces a higher heart rate than the other positions.

Index Terms—Design of experiment, handle position, manual material handling, physiological, psychophysical.
