This study examines the factors influencing consumer purchasing decisions on TikTok Shop in Surakarta, focusing on price perception, perceived ease of use, and perceived risk. Using a quantitative approach, data were collected from 100 respondents and analyzed through multiple regression analysis, t-tests, and F-tests. The results indicate that price perception (p = 0.004) and perceived ease of use (p = 0.030) significantly influence purchasing decisions, while perceived risk (p = 0.000) has the strongest impact, reflecting consumer concerns about security and product authenticity. The F-test (p = 0.000) confirms that all three factors simultaneously affect consumer purchasing behavior. Additionally, the correlation coefficient (R = 0.729) indicates a strong relationship between the independent variables and purchasing decisions, while the coefficient of determination (R² = 0.531) suggests that 53.1% of purchasing decisions are influenced by these variables, with the remaining 46.9% explained by other factors. These findings highlight the necessity for competitive pricing, user-friendly interfaces, and trust-enhancing measures to optimize consumer engagement in social commerce. Future research should explore additional variables such as brand trust, social influence, and digital marketing strategies to provide a more comprehensive understanding of consumer behavior in online marketplaces.
