Abstract:
The research was conducted on May-June 2012 in the Sungai Mesjid,
Dumai, Riau Province. The purpose of this research was to determine the amount
of litter production, the content of carbon and the decomposition rate of litter in
Xylocarpus sp . The method in this research is a survey that conducted by
observation and sampling of litter on the ground, then followed by analised litter
in the laboratory of Marine Ecology Faculty of Fisheries and Marine Science,
University of Riau. Based on research that has been done, it is known that the
largest amount of litter production found in the largest amount of Xylocarpus sp
stands with the production value of 480 gbk/m2/60 day or 8 gbk/m2/day, while the
biggest value of carbon’s content present in the largest amount of litter production
with 50,2 % percentage contribution of carbon value per day at station I. For the
higgest decomposition rate of litter found in the smallest amount of Xylocarpus sp
stands at station III with 1,51 % percentage of decomposition rate per day.
