The rubber cooperative is an important agency to support the economy of the rubber farmer groups in Riau Province. But the number of active cooperative decline since 2014-2019. The goal of this study is to assess the aspect of collaboration between elements against cooperative progress. This research was examined both inactive and active cooperatives as a comparison. The chosen locations are the largest rubber producer in Riau Province namely, Kuantan Singingi Regency and Kampar Regency. The samples were taken by purposive sampling with amount of 300 people representing 150 from active cooperative and 150 from inactive one. The research samples were the elements of the rubber farmer cooperative consisting members, management, supervisors and employees. The data was carried out by structured and in-depth interviews. The collaboration was studied based on the interaction between cooperative elements with 8 indicators. The value resulted from the active rubber cooperative in this parameters is good-very good (76.10% -82.80%). In contrast, inactive cooperatives obtain very bad – good enough (20.00% – 60.00%). The main problems in inactive cooperatives come from the interactions between members and employees (X3), management with employees (X5) and supervisors with employees (X6) because all nine indicators have bad scores. Those problems effect the cooperatives progress in Riau Province.
