Abstract

Indonesia has a diverse and abundant biomass resource, such as bamboo, which has the potential to be an energy source. However, optimal utilization requires the right conversion techniques. This study examines the conversion of bamboo using pyrolysis at temperatures of 300 °C, 400 °C, and 600 °C, as well as biochar analysis using FTIR, SEM-EDX, and BET. The pyrolysis results show that the yield of biochar decreases as the pyrolysis temperature increases, while the yield of bio-oil increases up to a certain temperature before eventually decreasing due to further conversion into synthetic gas. The analysis of biochar characteristics shows that the largest surface area was found at a temperature of 400 °C with an area of 178.559 m²/g, while the largest diameter was obtained at a temperature of 600 °C, which is 2.4478 nm. The chemical composition of biochar at 400 °C has the highest carbon content at 93.73% and the lowest oxygen content at 5.06%. The adsorption test of biochar on lead (Pb) heavy metal showed that biochar at 600 °C had the best adsorption capacity, with the smallest wavelength in the metal solution being 0.0903 nm.
