This research was to compare the experimental design by the yield response surface method in three rubbers and six rubbers. In the process of cracking the paddy. The objective is to find the optimal value. This research has identified the variables, two variables and three variables, respectively, were analyzed of variance and found that the p-value was less, at alpha 0.005, confidence level at 95 percent. The adjustment of the judgment coefficient was equal to 97.35 percentage, and 96.55 percentage respectively. Test between six rubbers, and three rubbers, the use of six rubbers have the best efficiency and optimization. The design of six rubbers in paddy cracking, it is most likely to expand the market, or community enterprise. Throughout the community who are interested in the production process of rice husking of six rubbers. But there is a cost higher than the three rubbers type.
