ABSTRACT
Mangroves are plants that have an important role in providing very complex and potential food
components for the life of various thing at there and terrestrial biota. Mangrove's high
productivity is obtained from litter. Mangroves have dregs that has a very important function
for the mangrove ecosystem, including maintaining the fertility of forest soil. Soil and plant
fertility depend on the productivity and rate of litter decomposition. litter will decompose,
donate organic matter to forest soil, and become a source of food for fauna in the mangrove
ecosystem. The rate of decomposition of litter is a process of destruction for organisms that
occurs gradually so that the structure is no longer complex, but has decomposed into carbon
dioxide, water and mineral components. This study aims to determine the rate of litter
decomposition and the percentage of the leaf decomposition of S.alba mangroves in the Coastal
area. This research was conducted from August to September 2021. The method used in this
study was an experimental method, where mangrove leaf fall was taken and observed the
decomposition rate of S.alba mangrove leaf litter in the field for 28 days, and then dried the
mangrove leaf. S.alba at the Marine Chemistry Laboratory, Faculty of Fisheries and Marine
Affairs, Riau University. Based on observations, it can be seen that the average temperature
value ranges from 29.7 to 30.7˚C. The temperature at station I is relatively low compared to
the other two stations. The measurement of the degree of acidity (pH) obtained the same results
at each station, namely 7. For the measurement of salinity, the average obtained ranged from
34.3-35 ppt. The highest salinity is known to be at station III is 35 ppt. In the measurement of
Dissolved Oxygen (DO) the average value was obtained, which ranged from 4.60-5.89 mg/l.
The decomposition process of S.alba leaf dregs which was carried out for 28 days showed that
of rate of decomposition of S.alba mangrove leaf litter between stations, the highest rate of
decomposition, is at stasion II an average of 3.92 g/day with a percentage of decomposition.
81.9% while at station III the average decomposition rate obtained was 3.35 g/day with a
decomposition percentage of 75.8% and at station I is the station with the lowest rate of
decomposition, which has an average of 3.25 g/day with a decomposition percentage of 67,0%.
Keywords: Litter, Decomposition Rate, Percentage of Decomposition.
