This research had the following objectivies: a) determining the synergy of participation of each ele- ment (farmer and non farmer) in the development of rural agribusiness, b) finding solutions to the participa- tion constraints of each agribusiness chain, and c) finding sub models of community facilities. The research was conducted in Pati Central Java Province as a cassava-producing region and tapioca center. There were two populations of this study, they were: area of cassava land and center of agribusiness, and community members consisting of farmers element (cassava farmers), non farmer (owner of agribusiness and work- forces of agribusiness), and off farmers (owner of transport, transport drivers). Sampling technique used in this study was cluster sampling technique to find out agribusiness data and accuracy test of the accuracy of image interpretation in determining the number of samples using the guidelines of BIG (Geographyc In- formation Institution in Indonesia), as well as simple random sampling technique for agribusiness center. According to the calculation of correlation analysis, the results of the calculation of simple linear regression analysis produce a correlation coefficient of 0.801 and a determination coefficient of 0.642, which means that when linked to the interpretation table the correlation coefficient for correlation between variables is in the “very strong” interval level classification (0 , 80 - 1.00). The study recommended to increase the synergy of the participation of members of rural communities, accelerate networking between citizens or communi- ties through social planned change known as social engineering and labor intensive agricultural processing.

The success of the program needs to be supported by the community to realize the expansion of access to marke- ting, the sustainability of agribusiness and strengthening of capital in order to form sa- vings. Community as a regional unit (natu- ral and social) where its members (farmers and non-farmers) carry out various activi- ties of daily life, constituting social capital plays an important role in a development process. Networking between citizens has been formed. Community elements need to be empowered so that agribusiness busines- ses can process agricultural products before trading.
