Biochar technology is expanding due to its benefits in enhancing soil fertility, improving soil structure, increasing crop yields, and improving crop conditions (Gai et al., 2014; Ahmad et al., 2014). Biochar usage now extends beyond agriculture, serving as an alternative fuel, in wastewater treatment, and in climate change mitigation (Inyang et al., 2012; Kamarudin et al., 2022). This paper investigates the physicochemical properties of biochar derived from palm empty fruit bunches (EFB) and its performance as an adsorbent. Methylene Blue in aqueous solutions was used to assess adsorption capacity and surface area. Biochar was activated using potassium hydroxide (KOH) at varying concentrations. EFB activated with 3M KOH exhibited the highest adsorption capacity compared to those activated with 2M and 1M KOH. These results were supported by data on functional groups and pore structure, observed using Fourier Transform Infrared (FTIR) spectroscopy and the Brunauer-Emmett-Teller (BET) method.
