Abstract
In the process of painting a product, it commonly occur defect results including corrugated painting, perforated, less smooth, speckled and uneven surface of painting. This can occur due to the setting parameters in the process of painting is not appropriate. This research is done to reduce the high rate of defects in the process of painting products of table by setting parameters using the Taguchi method. Processing data using the Taguchi method are distinguished by two ways: (1) to see the impact of uncontrollable factors on the percentage of defective products and (2) to see the controllable factors to the variability of the number of defective products. Controllable factors in this study are: composition of paint, painting distance, pressure and temperature. The research results revealed that a significant factor level against average and variability of percentage number of defective products are composition of the paint level 2 (0.75: 1), the distance painting level 2 (20-25 cm), pressure level 1 (50 psi fluid tip round 1.88 mm), temperature level 2 (60 C), sanding sealer level 2 (15-20 cm) and a clear top coat level 1 (20-25 cm).
