Abstract

The study employed a quantitative approach with a causal-comparative design through a cross-sectional survey. A sample of 107 CV. Adi Jaya Mandiri customers was selected using a purposive sampling technique. Data were collected using an online questionnaire with a 5-point Likert scale and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The PLS-SEM results indicate that: Product certification has a direct positive and significant effect on purchasing decisions (β=0.343, p<0.05). Product certification also directly increases perceived quality (β=0.632, p<0.05) and consumer trust (β=0.641, p<0.05). Perceived quality (β=0.363, p<0.05) and consumer trust (β=0.279, p<0.05) have a positive effect on purchasing decisions. Perceived quality and consumer trust are shown to act as partial mediators in the relationship between product certification and purchasing decisions, with significant indirect mediation effects (β=0.229 and β=0.179, respectively, p<0.05). The research model has excellent predictive power with an R² value of 0.746 for the purchasing decision variable. Product certification is a crucial factor that not only directly drives purchasing decisions but also indirectly by improving perceived quality and building consumer trust. For CV. Adi Jaya Mandiri, proactive communication regarding certification, consistent product quality, and operational transparency are key to maximizing the positive impact of certification on consumer purchasing behavior.

Abstract

This study aims to analyze the effect of social media marketing and lifestyle on consumer purchasing decisions at Coffee Shout Haurgeulis, with income as a moderating variable. The research employed a quantitative method. The sample consisted of 132 respondents, determined using the Slovin formula. Data analysis was conducted using the Partial Least Squares–Structural Equation Modeling (PLS-SEM) method. The results indicate that social media marketing does not have a significant effect on purchasing decisions, while lifestyle has a significant effect. Income is proven to moderate the influence of lifestyle on purchasing decisions but does not moderate the effect of social media marketing on purchasing decisions. The R-square value of 0.307 indicates that purchasing decisions are influenced by the variables in the model by 30.7%, while the remaining variance is explained by other factors outside this study.
