<![CDATA[Indonesia's large Muslim population drives a high demand for halal food assurance, including soybean-based products such as tofu in traditional markets. This study aims to analyze the effect of the Halal Supply Chain comprising Raw Materials (X1), Halal Product Process (X2), and Final Product Condition (X3) on Tofu Product Halal Assurance (Y) based on the perceptions of traditional market traders in Banyumas Regency. The research adopted a quantitative survey approach with a sample of 38 tofu traders across four major traditional markets (Ajibarang, Cilongok, Karanglewas, and Purwokerto). Data were analyzed using Structural Equation Modeling - Partial Least Squares (SEM-PLS) via SmartPLS software. Outer model evaluation confirmed strong convergent validity with loading factors exceeding 0.9, AVE values of 0.888 (X) and 0.928 (Y), and internal consistency reliability with Cronbach's alpha above 0.97. Inner model results revealed a positive path coefficient of 0.961 and an R-squared (R2) value of 0.923, indicating that 92.3% of the variance in product halal assurance is explained by the halal supply chain. Hypothesis testing via bootstrapping confirmed a statistically significant positive effect (T-statistic = 23.871; P < 0.001). This study concludes that managing the halal supply chain from upstream to downstream is critical to maintaining tofu product halal assurance at the traditional market retail level.]]>
