The Cadmium Plating Process for aircraft actuation components at PT X faces quality issues due to instability in the activation Process using a sulfuric acid (H₂SO₄) solution, which causes Defects such as pitting, underetching, and Overetching . Defect data from 2025 indicates an increase in rework, production costs, and a decrease in Process efficiency. This study aims to analyze the causes of Defects, compare the effectiveness of the Sulfate and Sandblasting activation methods, and determine the optimal Sandblasting parameters to improve the quality of Cadmium Plating results. The study uses a quantitative approach with the Response Surface Methodology (RSM). Research data was obtained from the period June 2025–April 2026. The results of the One-Way ANOVA test showed a p-value of 0.000 (<0.05) and an F-value of 1709.46, indicating a significant difference between the two methods. The average number of Defects for the Sulfate method was 13 pieces, while for the Sandblasting method it was 4 pieces. Based on the RSM Analysis results, the optimal parameter combination was determined to be nozzle pressure, spraying time, and a nozzle distance of 5 cm. This study concludes that the Sandblasting method, optimized using RSM, is capable of improving the quality of Cadmium Plating results, reducing the number of Defects, and enhancing the stability of the production Process at PT X. The research results indicate that the Sandblasting method is more effective than the Sulfate method in reducing the number of Defects.
