<![CDATA[Robusta coffee is a leading commodity in Tutur Subdistrict, Pasuruan Regency, contributing to the local economy. However, limitations in processing technology, production capacity, and market access have prevented the full realization of robusta coffee's value-added potential. This study analyzes the impact of product, process, functional, and channel improvements on robusta coffee value chain performance at CV Kopi Citarasa Persada. Data were collected through questionnaires and interviews with 45 respondents, including farmers, processing staff, and distributors, using a census method, and analyzed using SEM-PLS with WarpPLS 8.0. Results indicate that the value chain involves farmers, processors, distributors, and consumers as key actors. All improvement variables had a positive and significant effect on value chain performance, with product improvement as the most dominant (β = 0.376; p = 0.003), followed by channel, functional, and process improvements. These findings indicate that improvement strategies can enhance the value added, efficiency, and competitiveness of robusta coffee, while strengthening farmers' bargaining power in the value chain.]]>
