The Estimation of CO2 Absorption and O2 Production from Trees on Main Street in the City of Jember

Abstract

One way to decrease the global warming effect is by planting trees on the side and in the middle of the street. Trees thathad already planted must be monitored to know how good those trees are in absorbing CO2 and producing O2. Therefore, the purpose of this research was to know the ability of the trees to absorb CO2 and produce O2 which had already planted in City Street; and this research can be used as a basis development for the next greenways area. The method that was used to estimate the absorption of CO2 and the production of O2 from trees was calculating carbon biomass of the trees firstusing alometric equations. Then, the value of biomass that had been known was multiplied by the conversion factor of CO2 and O2;therefore the absorption of CO2 and the production of O2 can be estimated. The result of this calculation showed that the trees, which had already planted on Gajah Mada Street,PB Sudirman Street, and Letjen Panjaitan Street, had the capability to absorb all of the CO2 emission that comes from vehicle activity. The result also showed that Glodokan Tiang (Polyalthialangifolia) can absorb CO2 and produce O2 more than all tree species which were found in that street.
