Abstract

Sand sieving machine has the function to sieve sand and stone that mixed together. The sand and the stone cannot process further if they mix. Thus, this machine will help operator work which was doing sieve with no machine mechanism. With machine mechanism driven by human power will reduce the time to sieve. The objective of this paper is hopefully can make the best concept design in terms of production costs and production capacity. The stages of evaluation design begin with functional decomposition, concept making with morphology matrix and concept evaluations with feasibility judgment, go or no go screening and basic decision matrix. In evaluating the product, one or several of the best concepts are chosen to further developed into products, based on selection criteria. The results of this design obtained the best concept of sand sieving machine in terms of efficiency, energy, and flexibility. From this paper, it can be concluded that the design of this sand sieve will environmentally friendly and bring many benefits, is positive and very good to continued.
