Optimization of Factorial Design with the type of Plackett-Burman Design to Study the Effects of Organic Rice Production Process: Second Step Experiment

This research conducted the second experiment is to evaluate the results of organic rice production by controlling two variables. To consist of the spindle of speed and clearance between the rubber and two levels. The test statistics will be used. Factorial design Choose the type of Plackett-Burman design. Both variables and experiment levels have the effect of organic rice production process at the level of significance. To study the interaction among the factors a 36 factorial experiment approach has been adopted using the two basic principles of experimental design, replication and randomization. The process model was formulated based on Analysis of variance (ANOVA) and regression of coefficient using Minitab Release 15.00. The results showed that both variables were p value is greater than alpha value (0.216 > 0.05). There are no significant differences. Shows that the SS and CL is significant to the effect of organic rice production process. So, the conclusion is accepting H0
