Seagrass is a sea plant capable of storing carbon in the form of biomass which is absorbed by plants through photosynthesis, thus the seagrass plays a tremendous role in mitigating global climate change issues. This study was conducted in April 2016 in seagrass ecosystems of Malang Rapat village Bintan Regency of Kepulauan Riau Province. Analysis of seagrass biomass and carbon reserve was carried out in Marine Chemistry Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The results showed that six species of seagrass were identified in the region, where Cymodocea rotundata was found to be the dominant species whilst the smallest number of species found was Halophila minor. Total biomass and carbon reserve in seagrass was 210.58 tons dry weight/ha and 71.60 tons C/ha. Carbon reserves in seagrass has no significant difference at a distance of 0 m, 50 m and 100 m from the coastline. The high potential of biomass and carbon reserve in seagrass ecosystems illustrates the magnitude of this ecosystem role in tackling the adverse effects of global warming by absorbing carbon dioxide and store it in the form of biomass. It can also be used as a reference in planning the conservation program and mitigation of global climate change issues.
