The research employed a descriptive-verificative approach with a quantitative method. The population consisted of all customers of PT Siso Extra Indonesia during the period 2022–2024, totaling 383 customers, with a sample of 196 respondents selected using purposive sampling. Data were collected through a Likert-scale questionnaire and analyzed using multiple linear regression analysis. The results indicate that service quality has a positive and significant effect on customer satisfaction with a significance value of 0.007 (< 0.05). Product quality does not have a significant effect on customer satisfaction, as indicated by a significance value of 0.131 (> 0.05). Simultaneously, service quality and product quality have a significant effect on customer satisfaction with a significance value of 0.013 (< 0.05). The coefficient of determination (R²) of 0.044 shows that 4.4% of customer satisfaction is explained by service quality and product quality, while the remaining percentage is influenced by other factors outside the research model. The findings highlight that service quality plays a dominant role in enhancing customer satisfaction in institution-based garment industries.]]>
