Abstract

This study examines the effects of brand image and product quality on purchase decisions among Generation Z consumers of Kopi Jago in South Jakarta. A quantitative approach using Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed with 100 Generation Z respondents who had previously purchased Kopi Jago products. Data were collected through an online questionnaire and analyzed using SmartPLS 3.2.9. The findings indicate that brand image does not significantly affect purchase decisions (T-statistic = 0.444; p-value = 0.657), whereas product quality has a positive and significant effect (T-statistic = 3.561; p-value < 0.001). The model explains 37.6% of the variance in purchase decisions (R2 = 0.376). These results suggest that product quality is the dominant determinant of Generation Z purchasing behavior, while brand image plays a supportive but not decisive role. The study contributes to the understanding of consumer behavior in emerging lifestyle coffee brands and provides managerial implications for improving product-driven value propositions.
