Abstract

This study aims to analyze the influence of TikTok Shop-based sales promotions on purchase intention and purchase decisions, the influence of purchase intention on purchase decisions, and the role of purchase intention in mediating the effect of TikTok Shop-based sales promotions on the purchase decisions of Roti Gembong Gembul consumers in Palembang City. A quantitative approach using a survey method was employed. Purposive sampling was used to select 107 respondents who had viewed promotions for and purchased Roti Gembong Gembul via TikTok Shop. Data were collected through questionnaires and analyzed using the Structural Equation Modeling-Partial Least Squares (SEM-PLS) method with SmartPLS 3 software. The results indicate that TikTok Shop-based sales promotions have a positive and significant effect on purchase intention. However, TikTok Shop-based sales promotions do not have a significant effect on purchase decisions. Purchase intention has a positive and significant effect on purchase decisions. Furthermore, purchase intention was found to significantly mediate the effect of TikTok Shop�based sales promotions on purchase decisions, demonstrating full mediation. These findings suggest that sales promotions via TikTok Shop are more effective at driving purchase decisions by first fostering consumer purchase intention. Therefore, promotional strategies should focus on building consumer interest before encouraging purchase decisions. Keywords: Sales Promotion, TikTok Shop, Purchase Intention, Purchase Decision, SEM-PLS.
