The productivity of the mangroves ecosystem is depending on the litter fall. The
decomposition process of litter fall is divided into two phases which are rapid weight
loss and slower decomposition. Slower decomposition occurs due to the deterioration
of structural and refractory materials like lignin. Lignin is a class of complex organic
polymers that form important structural materials in the support tissues of vascular
plants and some algae. Thus, this study was conducted to investigate the lignin
content and to identify its effect towards the decomposition rate of mangrove litter
(Rhizophora Apiculata sp. and Ceriops Zippeliana sp.) Klason method has been applied
in this study which were divided into acid soluble and insoluble lignin. We expected
Rhizophora Apiculata sp. contain high lignin content resulted in slow decomposition
rate than the other species. As a conclusion, lignin content does affect the
decomposition rate of the litter fall.
