SUMMARY The high composition of fiber and carbon compounds (lignin, cellulose and hemicellulose) in rubber fruit shells 98.99%, can be used to make activated charcoal. In this study physical activation was carried out on rubber fruit shells activated with 10% KOH with temperature (400; 500; 600)oC and time (15; 30; 45) minutes. This study aims to improve the character of the activated charcoal of rubber fruit shells and to determine the best conditions for the activated charcoal of rubber fruit shells based on the characterization water content, ash and iodine adsorption capacity and functional groups using FTIR and surface area, pore diameter and total pore volume using SAA (Surface Area Analyzer) with the BET method (Brunauer Emmet Teller). The carbonization process was carried out at 400oC for 30 minutes to produce rubber fruit shell charcoal, then followed by chemical and physical activation processes. Chemical activation using 10% KOH in 100 mL of demineralized water. The rubber fruit shell activated charcoal was then physically activated using a furnace with a temperature of (400; 500; 600)oC and time (15; 30; 45) minutes. Rubber fruit shell activated charcoal is characterized according to SNI No. 06-3730-1995, including: yield, water content, ash content, and iodine adsorption capacity. The best results for rubber fruit shell charcoal adsorption were obtained at 600oC for 45 minutes with an iodine adsorption capacity of 1.429.59 mg g-1. The results of the characterization of activated charcoal from rubber fruit shells had the highest yield of 92.12%, a water content value of 0.12% and an ash content of 1.18%. The results obtained from the water content, ash content and iodine adsorption capacity have met the SNI standard no. 06-3730-1995.
