Litter is one of the sources of soil organic matter that develops through the decomposition process, which is overhauled and broken down into smaller particles, producing dissolved nutrients. Therefore, this research aims to determine the litter production from forest land conversion in mixed gardens as a basis for sustainable forest management. The method used is a field survey, in which direct observations were carried out. Subsequently, the types of data collected include primary data by observing the production of litter for two weeks, which comprises the wet weight and dry weight of the litter and the average production of its components, as much as 1 ha. The results showed that Theobroma cacao had the highest litter production in mixed gardens at 1.24 tons/ha/year, while Lansium domesticum had the lowest litter production at 0.06 tons/ha/year, and the most litter contribution comes from the leaves by 60% - 67%.
