The observation of termites was conducted using transect method. Parameters observed were environmental parameters, soil physical and chemical characteristics. The total diversity of termite species found was 15. Diversity of trees, nekromas, and the amount of litter that is higher in secondary forest than in agroforestry cause soil water content and moisture become higher in secondary forests and there fore contributes toan increase in soil organic matter content. Key Words : Agroforestry, diversity of  termite, forest use change, secondary forest.
