In conclusion, the Dioscorea. hispida tubers traditional harvester design was improved by means of shape alteration. The bent form was chosen as the best form for the hand tool. The Aluminum Alloy material was selected to be applied to the hand tool solid model for being light in weight. FEA was successfully implemented on the solid model of the hand tool harvester in CAD system. The FEA simulation predicted the stress distribution under the applied pressure due to the harvesting process. In comparison to other materials the Aluminum Alloy showed the least stress value during Dioscorea hispida tuber harvesting process. Finally, a prototype was fabricated for testing the hand tool during the harvesting process, which demonstrated a portable and easy to use hand tool. Further use of technology such as mechanization and lighter material is still an open opportunity for future research
