| dc.description.abstract | Mangrove forests were a typical type of tropical and subtropical forest, growing along beaches or river mouths
that were affected by tides. Mangroves were often found in coastal areas that were protected from the onslaught
of waves and sloping areas. Mangrove forest ecosystems had the function of absorbing carbon dioxide (CO2)
from the air and storing carbon in the form of biomass. This research was conducted in September 2017. This
study aimed to determine the growth, carbon stocks and biomass in mangrove forests in the area of Taman Hutan
Raya Ngurah Rai (Sanur) Denpasar. Making research plots used the transect method with a size of 20 meters x
50 meters as many as 3 plots along the coast. From the measurement results, the total value of the base area in
plot A was 2.37 m2 / tree, branch-free volume was 16.57 m3 / tree, biomass was 13,591 tons / plot, carbon stock
was 6,795 tons / plot, the average increment was 0, 29 cm / year / tree. While the results of the measurement of
the total value of the base area in plot B was 13.20 m2 / tree, branch-free volume of 14.87 m3 / tree, biomass of
8,420 tons / plot, carbon stock of 4,210 tons / plot, average increment amounting to 0.39 cm / year / tree.
Furthermore, the total value of the base area in plot C was 12.96 m2 / tree, branch-free volume was 14.83 m3 /
tree, biomass was 8,265 tons / plot, carbon stock was 4,132 tons / plot, the average increment was 0, 40 cm / year
/ tree. The salinity value of plot A = 0.10% with a pH of 6.68, plot B = 0.09% with a pH of 6.78 and plot C =
0.08% with a pH of 6.78. Based on the calculation results, it could be concluded that the total biomass value of
plot A = 13,592 tons / plot, plot B = 14,866 tons / plot and plot C = 8,265 on / plot and then carbon stock plot A =
6,796 tons / plot, plot B = 8,420 tons / plot and plot C = 4.133 tons / plot. The average increment per tree
obtained values for plot A = 0.29 cm / tree / year, plot B = 0.39 cm / tree / year and plot C = 0.40 cm / tree / year. | en_US |
