Biomass waste is currently being optimized to increase its use value and selling value on the market and reduce the impact of environmental pollution. Trembesi tree trunks (Samanea Saman) are waste that is often thrown away after being cut down. For this reason, this research has successfully utilized trembles tree trunk waste as active carbon using a KOH activator. The successful identification of active carbon synthesis was characterized using XRD, which showed an increase in crystal size from 9,902 nm to 14,207 nm. Functional group testing showed a relatively increased formation of carbon functional groups. The morphology of activated carbon shows an increase in pore size from 1537.1317 nm to 1597.3977 nm. The resulting surface area was 807,079 m2/g with an average pore size of 3.886 x 101 Å. These characterization tests provide important information for applying activated carbon on a wider scale.
