This study investigates the factors influencing donation decisions on the BagiBagi.co platform, particularly focusing on Perceived Ease of Use (PEOU), Perceived Security (PS), User Satisfaction (US), Trust (UT), and Intention to Donate Again (ITD) using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results show that Convergent Validity is supported, with outer loadings, Composite Reliability (CR), and Average Variance Extracted (AVE) all exceeding the recommended thresholds, indicating that the constructs are measured reliably. Discriminant Validity is also confirmed, as the square root of AVE for each construct is higher than the correlations with other constructs, ensuring the distinctness of the variables.The Hypothesis Testing supports all four tested hypotheses. PEOU has a strong positive influence on Trust (UT) (path coefficient = 0.873), indicating that a user-friendly platform significantly enhances trust. PS also positively impacts Trust (UT) (path coefficient = 0.731), though to a lesser extent. User Satisfaction (US) positively influences Intention to Donate Again (ITD) (path coefficient = 0.771), while Trust (UT) strongly influences ITD (path coefficient = 0.751). All relationships were found to be statistically significant with t-values well above 1.96 and p-values of 0.
