    Pendugaan Kandungan Karbon Di Atas Permukaan Tanah Pada Kawasan Arboretum Universitas Riau
    (2016-02-10) Pratamasari, Ricky; Sribudiani, Evi; Sulaeman, Rudianda
    Forests be able to absorb carbon dioxide (CO2) and convert it into carbohydrates in the form of carbon and saved it in biomass components of forest. Arboretum area is one of forest area, which is around the Riau University, has the potential of biomass carbon saved in the constituent components. This research aimed to obtain information about the value of the carbons potential in the above ground at arboretum area of Riau University. The carbons potential at the area is one of the benefits of ecosystem services that have economic value, so its existence worthy of attention. Techniques of data collection was done by using the method purposive sampling or transect lines. Above ground biomass estimation was done by summing the biomass of litter, seedlings, undergrowth, saplings, poles and trees. Biomass of saplings, poles and trees was estimated by employing Ketterings et al., (2001). Biomass of litter, seedlings and undergrowth was estimated by employing Indonesian National Standard (SNI 7724: 2011). Value of carbon saved is 0,47 of the biomass. The research results showed that the carbon potential at arboretum area of Riau University is 58,45 ton/ha.
