Rhizophora mucronata leaf litter is a source of organic material for several organisms found in mangrove forest ecosystems. Leaf litter that falls on the forest floor will undergo a process of decomposition by biological agents within a certain time period. One effort to accelerate decomposition process is the use of fungi Aspergillus fumigatus . The purpose of this study was to measure the rate of decomposition and to measure the levels of carbohydrates and proteins contained in R. mucronata litter with different levels of salinity in the mangrove area of Hamparan Perak District. Carbohydrate and protein analysis is carried out at the Medan Industrial Research and Standardization Center. The average decomposition rate (k) of R. mucronata leaf litter at the 0-10 ppt salinity level is 10.89, the 10-20 ppt salinity is 7.74 and the 20-30 ppt salinity is 7.81. The Leaf Litter of R. mucronata experienced a decrease in carbohydrate levels. The highest carbohydrate content was found in Observation I station 3 which was 12.2% while the protein content in R. mucronata litter had increased. The highest protein content was found in observation VI of station 3 which was 6.78%. The decomposition rate in Belawan waters shows that productivity is good.
