This study aims to prove whether product innovation affects purchasing decisions for custom t-shirts with quality as a moderating variable in Sarkastem Lampung Tengah. This study uses quantitative research methods. The sampling method used was purposive sampling with a sample size of 95 respondents. This study uses SEM-PLS (Structural Equation Modeling - Partial Least Squares) data analysis measurement tools with the SmartPLS program. The results of this study indicate that product innovation has a positive and significant effect on purchasing decisions and product quality can affect the relationship between product innovation and purchasing decisions, but in a negative direction, namely weakening the relationship between the two.

Abstract

Increasingly fierce market competition, driven by digitalization and social connectivity, places Brand Trust as the most critical non-financial asset an organization possesses. Brand Trust has long been proven to directly influence Customer Satisfaction because it reduces risk and uncertainty in purchasing decisions and service usage. However, the digital era has introduced a new dynamic variable, namely User Generated Content (UGC)- content created by consumers (such as reviews, testimonials, unboxing vlogs , and social media comments) rather than by the brand itself—which serves as a source of information that is inherently perceived as more credible and authentic. This study aims to examine and analyze the role of UGC as a moderating variable in the causal relationship between Brand Trust and Customer Satisfaction, specifically in the context of the [Specify specific context, e.g., e-commerce or hospitality industry] market. Using a quantitative approach with a hierarchical regression model (Moderated Regression Analysis), this study tests the hypothesis that the positive impact of Brand Trust on Customer Satisfaction will be strengthened (positive moderation) when Customers are exposed to high and consistent volume and quality of UGC, or conversely, the impact can be weakened by negative UGC.
