Abstract : Integrated farming systems are increasingly promoted as farm-level strategies to improve resource-use efficiency, reduce dependence on external inputs, and strengthen smallholder resilience. In coffee-based farming areas, goat–coffee integration offers a circular model in which goat manure can be processed as organic fertilizer for coffee plantations, while farm vegetation and surrounding biomass may support livestock feed availability. This study examines the behavioral determinants of farmers’ intention and adoption of goat–coffee integrated farming systems in East Java, Indonesia, using an extended Theory of Planned Behavior framework. Survey data were collected from 230 coffee farmers in Madiun (n = 110) and Bondowoso (n = 120) and analyzed using partial least squares structural equation modeling with SmartPLS 3.0. The results show that the model explained 56.9% of the variance in intention and 58.1% of the variance in adoption. Attitude, subjective norms, perceived behavioral control, injunctive group norms, and descriptive group norms positively and significantly influenced intention. Adoption was directly and significantly influenced by intention, perceived behavioral control, descriptive group norms, and attitude, whereas subjective norms and injunctive group norms had no significant direct effect on adoption. All indirect effects through intention were significant. These findings indicate that adoption is shaped by both motivational and implementation-capacity pathways. Extension programs should therefore combine benefit communication, peer-based demonstration, farmer-group mobilization, and practical assistance in manure processing, feed planning, and low-labor integration practices.
