Abstract
Manual grass-flower beating in traditional broom production often results in inconsistent efficiency and material damage, limiting the productivity in rural communities. This study proposes a novel hybrid optimization framework combining the Taguchi L9 orthogonal array with the Weighted Aggregated Sum Product Assessment (WASPAS) method to enhance the performance of an automated grass-flower beating machine. Three key parameters: the rotational speed, beating time, and feedstock weight, were optimized to maximize the efficiency and minimize the damage. The experimental results identified optimal settings of 100 rpm, 120 s, 120 g, yielding an average efficiency of 95.50% and a low damage score of 1.23. The novelty of this work lies in the first application of Taguchi–WASPAS to optimize the community-scale broom production equipment. The proposed approach provides a cost-effective, replicable solution for improving the product quality and reducing the labor dependency. Future studies should incorporate additional variables and predictive modeling to support a broader implementation in sustainable manufacturing systems.
