Based on the results of the research that has been carried out, the role of rubber agroforestry is divided into 2 parts, namely, rubber plants for sale, and intercrops play a role for sale, self-consumption, and taken by land owners. The contribution from intercropping was only 4 people who sold the intercrops in the form of fruit, the largest income from the intercropping was Rp. 12,000,000 with a percentage of 19% of the total income of Rp. 63,200,000. There are two factors that affect the agroforestry system, namely internal factors based on farmers' experience, motivation to carry out the rubber agroforestry system, land area, number of plants other than rubber, and types of plants other than rubber, while external factors are the absence of support by rubber agro-forestry extension agencies in Maburai Village, and community leaders.
