| dc.description.abstract | Increased urban activity and population growth in Medan City contribute to
increased carbon dioxide (CO2) emissions, which have an impact on climate
change. Green Open Spaces (GOS) play an important role as emitter absorbers
through the process of carbon sequestration. This study aims to determine the
carbon sequestration potential of three GOS in Medan City: Maharani Park,
Ahmad Yani Park, and Cadika Park. The research method involved measuring
carbon reserves in four carbon pools, namely above-ground biomass (trees, poles,
stakes, seedlings, undergrowth), litter, necromass (dead trees and dead wood), and
soil organic matter. Data collection was carried out through a combination of
destructive and non-destructive sampling methods. Biomass, carbon stock, and CO2
sequestration potential calculations were analyzed using allometric equations and
laboratory test results. The results showed that Cadika Park had the highest carbon
sequestration potential at 25,404 tons/ha, followed by Ahmad Yani Park at 6,288.11
tons/ha, and Maharani Park at the lowest at 3,618 tons/ha. Among all carbon pools
measured, soil organic matter was the largest carbon store in all three locations.
This study concluded that green spaces in Medan City, especially Maharani Park,
have enormous potential to absorb CO2, and soil organic matter management is an
important factor in maximizing the ecological function of urban green spaces. | en_US |
