User Centered Design : Design and Development Methodology of Seed Planting Tools

摘要

Gejlek or Galah is a conventional wood-made seed planting tools aid common used by corn farmers. The limited functions and heavy weight of the existing seed planting caused low productivity and long duration in planting activity. The aim of the research is to design and to develop seed planting tools which able to accommodate user needs. User-Centered Design (UCD) methods used to design product focused on customer satisfaction. 15 respondents involved in this research to measure productivity, practicality, reliability and ergonomic. Validity test represent by F-value produce result test in between 0.354 to 0.625 where F_(test)> F_(tab) means reject Ho or seed planting tools design able to fulfd user needs and different from previous design. User test show how work load against pulse measurement improve 26.44% and Nordic Body Map decrease by average 25% which mean there are sigmficant improvement in terms of work load and ergonomics. It helps increase work productivity.
