Analysis of the Influence of Product Quality, Price, and Service on Consumer Satisfaction at Janji Jiwa Coffee

Abstract

This study investigates the impact of product quality, price, and service on consumer satisfaction at Janji Jiwa Coffee Shop in Kotabaru, Yogyakarta. Utilizing a quantitative approach, data were collected through questionnaires from 114 customers, selected via purposive sampling, who had made at least two purchases. The data were analyzed using multiple linear regression analysis with SPSS version 30.

The findings demonstrate that all three variables individually have a positive and significant effect on consumer satisfaction. Furthermore, the analysis confirms that product quality, price, and service simultaneously exert a significant combined influence on satisfaction levels. The model explains 39.1% of the variance in consumer satisfaction (Adj. R² = 0.391). These results offer valuable insights for the management, highlighting that enhancing product quality, maintaining competitive pricing, and improving service standards are key strategies for increasing customer satisfaction at the coffee shop.
