Abstract
The increasingly competitive food and beverage (F&B) industry requires companies to provide high-quality services that can maintain customer loyalty. Vilo Gelato Tomang, West Jakarta, is a local gelato business that prioritizes product innovation and service quality. However, based on the observation results, there was a decline in the frequency of repeat customer visits in 2025, indicating a potential decrease in customer loyalty. This study aims to determine and analyze the effect of service quality on customer loyalty at Vilo Gelato Tomang, West Jakarta. This study employed a positivist paradigm with a quantitative approach and survey method. The theoretical framework used was Grönroos’ Service Interaction Quality Theory and the SERVQUAL concept developed by Parasuraman, Zeithaml, and Berry. The service quality variable was measured through the dimensions of tangibles, reliability, responsiveness, assurance, and empathy, while customer loyalty was measured through repeat purchase, referrals, retention, and share of wallet. The study involved 100 respondents selected using a purposive sampling technique. Data were collected through questionnaires and analyzed using IBM SPSS Statistics 25 through validity, reliability, normality, Pearson correlation, simple linear regression, t-test, and coefficient of determination tests. The results showed that service quality had a positive and significant effect on customer loyalty. The correlation coefficient value of 0.593 indicated a moderate positive relationship. The t-test result obtained a significance value of 0.000 < 0.05; therefore, H₀ was rejected and H₁ was accepted. The coefficient of determination (R²) value of 0.352 indicated that service quality contributed 35.2% to customer loyalty, while the remaining 64.8% was influenced by other factors outside the scope of this study.
