摘要:Farmers institution is developed under the expectation to be dynamic, robust, and independent to fulfill farmers’ needs, improve competitiveness, and support business continuity. In agribusiness context, BUMP (Badan Usaha Milik Petani/Farmer-owned Enterprise) is an institution which covers the production, distribution of farming system production means, storage, processing, and marketing, as well as empowers the farmers by improving their capacity, farming system, environment, and institution. The research is aimed at analyzing the factors (farmers’ personality and participation, and stakeholders’ role) influencing the effectiveness of BUMP in farmer empowerment in Central Java. It applies quantitative method with respondents of 336 farmers who are involved in BUMP activities and selected using simple random sampling, to further be analyzed using SEM at α=0.05. Research result indicates that stakeholders’ role does not influence farmers’ participation and BUMP effectiveness in empowering the farmers. Instead, such effectiveness is significantly influenced by farmers’ personality, i.e., their motivation, confidence, and participation. The farmers have decent confidence and motivation as well as great participation towards BUMP effectiveness to improve farmers’ capacity, environment, institution, and satisfaction of the role of BUMP. To enhance BUMP effectiveness in theempowerment, other personality of the farmers need to be improved, i.e. farmers’ attitude towards BUMP activities in Central Java. Empowering their attitudes will encourage them to participate more actively. In addition, improvement should also be made to BUMP cooperation with stakeholders, such as national and regional governments, universities, and private sectors.
