The research method used is a quantitative approach with a correlational design.

Data analysis was conducted using multiple linear regression with the assistance of SPSS software. The results indicate that partially, both product quality and service quality have a positive and significant effect on consumer purchase intention. Simultaneously, both variables also have a significant effect, with a coefficient of determination of 0.750, indicating that 75% of the variation in purchase intention can be explained by product and service quality.

Therefore, improving both product and service quality simultaneously can be an effective strategy to enhance consumer purchase intention.
