【 摘 要 】

Seagrass has the ability to store carbon through photosynthesis. The ability is influenced by environmental factors. This study was aimed to examine the diversity of seagrass and investigate the carbon storage in seagrass' biomass in two stations at Teluk Bakau Village, Bintan Island. This research was conducted at two stations including Beralas Pasir Island (small island) and Teluk Bakau Village Beach (mainland). Measure of seagrass biomass with dried seagrass sample was carried out at 60°C temperature. The analysis of carbon content was carried out on the biomass of the four dominant seagrass species found in the Teluk Bakau Village namely Cymodocea rotundata, Enhalus acoroides, Syringodium isoetifolium, Thalassia hemprichii. The results show that the carbon storage on seagrass has a correlation with seagrass biomass. Enhalus acoroides has the highest carbon content compared to the other three seagrass species. In general, seagrass located in Teluk Bakau Village Beach have higher biomass than seagrass located in Beralas Pasir Island, and it means that they have high carbon storage. This is expected to occur considering that the area of Teluk Bakau Village Beach is close to the mainland, where there is a high nutrient input support for the growth of seagrass biomass.
