Mapping variables and key actors in corn farming in Dompu district: A development of economic institutional models in the agribusiness sector

One of the important and strategic aspects in developing entrepreneurship in the agricultural sector, especially corn commodity, is the institutional aspect. Institutions have an essential role in reducing production costs and transaction costs to improve farm profits and impact economic growth. This study aimed to map the key variables and actors in reducing transaction costs in maize farming in Dompu Regency, West Nusa Tenggara. Data collection techniques in this study used questionnaires, expert interviews, and focus group discussions (FGD). Data analysis in this study used the prospective analysis method with the MICMAC and MACTOR tools. MICMAC performs critical variable mapping analysis, while MACTOR performs strength analysis between objectives and actors. The MICMAC analysis results show that 10 key variables determine the success of the development of corn farming in Dompu Regency, West Nusa Tenggara, namely the input market, capital, land, pesticides, seeds, fertilizers, labor, pests, bonds, and output markets. MACTOR analysis shows that the relationship between actors has weak direct interactions. We need a collaborative and integrative institution that is formed at the local level through the Village Integrated Agribusiness Service Center (PLATDes) and BUMDes in the form of BKD and UDes legal entities.
