Rajawali II Sindanglaut Unit, Cirebon Regency. The research method used was quantitative with a survey approach involving 110 sugarcane farmers selected through proportional random sampling. The data were analyzed using Structural Equation Modeling (SEM) with SmartPLS. The results indicate that contract farming, information sharing, and communication quality significantly affect supplier performance. Furthermore, supplier performance is proven to enhance sugar product competitiveness. The contract farming variable contributes the largest total effect (0.417), followed by communication quality (0.460) and information sharing (0.179).
