摘要：Activated charcoal is charcoal that has activated for increasing its surface area by opening the pores so that increase the adsorption power. The surface area of the activated charcoal is between 300 and 3500 m 2 /g. Adsorption power from activated charcoal is very large, i.e. ¼ to 10 times the weight of activated charcoal. Activated charcoal is a good adsorbent for the adsorption of gases, liquids, and solution. Characteristics of activated charcoal which are moisture content, ash content, and absorption of the iodine. Manufacture of activated charcoal begins with soaking for 24 hours using 2N H 2 SO 4 solution, after it was drained and then roasted to remove the remaining water. Moisture content test was doing by weighing 1 gram of activated charcoal and then put it ini the oven at 105-110 0 C temperature for 120 minutes. Ash content test was by weighing 1 gram of activated charcoal and put in the furnace at a temperature of 500 0 C for 30 minutes, raise the temperature to 815 0 C for 90 minutes. Determination of the absorption of iodine is to weigh approximately 0.5 gram of activated charcoal and mix with 50 ml of iodine solution 0,1 N. Shake it for 15 minutes. Take 10 ml of the sample solution and titrate with natrim thio sulfate solution 0.1 N. Adding amylum solution of 1% as an indicator to the titration result becomes colorless. Pada penelitian ini dihasilkan kondisi optimum pada suhu pengovenan 1000 o C selama 60 menit. Arang aktif yang didapatkan pada kondisi ini memiliki kemampuan adsorbsi yang baik dengan kadar penyerapan iod yang tinggi sebesar 529,94 mg I 2 /gram arang. In this research produced the optimum conditions of oven temperature 1000 0 C for 60 minutes. Activated charcoal obtained under these conditions has a good adsorption capability with high levels of iodine absorption of 529.94 mg I 2 /g charcoal.
