Dioscorea hispida (D. hispida) is a poisonous plant normally found in wildlife forest where scientific studies have shown that its tuber contains toxic poison and can be consumed after its poison is removed. Traditionally the tubers were placed in flowing river water for several days. In harvesting aspect, an composite hand tool was conceptually designed to improve the traditional hoe or “cangkul”. The essential development on an composite hand tool harvester is required since harvesting the tuber of D. hispida is time consuming and difficult while the existing hand tool is heavy. Using IMADA digital force gauge to measure the force required for pulling out the tuber, combined with reverse engineering methods, these were used to design and develop the conceptual composite hand tool. The results from experiments showed that the force required for harvesting the D. hispida tuber is found significant with its weight where its regression squared (R2) of 0.86. The information from the experiments is used to model and simulate the tool in Computer Aided Design (CAD) environment. The solid modelling software, SolidWorks, was used for designing, simulation and modelling of the equipment and the finite element analysis to determine the stress affected on selected material of hand tool was simulated by uploading the material characteristic on simulation program embedded in SolidWorks software. The end result of the simulation is based on visualization of analysis in SolidWorks while producing the hand tool for designing and fabrication from material which is lighter and stronger.
