ERGONOMIC DESIGN OF THE CORN SHELLER MACHINE FOR IMPROVING PRODUCTIVITY USING AXIOMATIC DESIGN

Abstract

The common problems in post harvesting the corn is to split it safely, comfortably and effectively. This is indicated that 90% of workers experience discomfort at hands, back and legs when splitting a corn. And also they complained difficulties in using the exciting Sheller machine such that a target cannot be achieved on time. It results in decreasing of productivity. Thus it is important to improve a tool. The purpose of this study is to design the corn Sheller machine to improve comfort ability and productivity of workers. Survey was conducted to identify user attributes by distributing questionnaires. Anthropometric data is used to design. And design parameter will be developed by using axiomatic design method with mapping process from user attributes and functional requirement. Statistical analysis was conducted to validate the proposed design. Result of this study is an ergonomic design of the corn Sheller machine that satisfying user criteria namely adjustable, durable, multifunction, comfortable, and interesting design. This purposed design is also valid to improve 60% of work productivity and reduce of complaint/discomfort.
