Each part of samples was carbonized by heating at 500 ˚C for 2 hours before grinding to fine powders. The physical and chemical properties, including thermal analysis, iodine and methylene blue absorption capacities, ash and sulfur contents, study of pore size by SEM and moisture content, were determined. The results showed that the optimal heat capacity with the best value of 3,555.27 cal/g was found in the 9-month-sample. The maximum iodine absorption (2,315.025 mg/g) was shown in the 6-month-sample, while maximum methylene blue absorption (98.30 %) was in the-24-month-sample. The 15-month-bamboo gave the highest ash (10.82 %) with sulfur content of 0.82 %. The study of charcoal pore size by SEM found the biggest pore with 20 µm for the bamboo aged of 18 months. The results showed no effect of aging to moisture content.&nbsp;</p><p><strong>Keywords:</strong> Kim Sung bamboo, charcoal, heat value</p> ER -
