The research uses questionnaire showing the responses of farmers and ordinary people to collect the data. In addition, an interview showing the importance and the factor of implementing farmer cooperatives. This study uses interviews and questionnaire to gather the data needed to fill the gaps. The findings of this research add deep discovery to the previous studies, regarding the unawareness and knowledge among farmers about the importance, causes and positive effects of cooperatives among farmers and the negative effects that may occur to farmers for refusing to enter farmers' cooperatives and the factors of implementing farmer’s cooperatives.
