    The oil palm fronds contribute the highest biomass compared to other parts of the oil palm. The biomass of oil palm fronds were transformed into activated carbon through a carbonization process (at a temperature of 600°C for 60 minutes), resulting as charcoal, namely APS. Subsequently, the APS was chemically activated with KOH (APS : KOH ratio of 1:1 [w/w]) and physically activated under microwave irradiation (at times of 1, 3, and 5 minutes) at a power of 300 W, yielding activated carbons denoted as A1D300, A3D300, and A5D300. The moisture and ash content, as well as the iodine adsorption capacity of both oil palm charcoal and activated carbon were determined in accordance with the Indonesian National Standard (SNI) No. 06-3730-1995. Similarly, their respective yields were also assessed. The research results were found that yields, moisture content, and iodine adsorption capacity decrease with increasing irradiation time, whereas ash content tends to increase. The yield for each activated carbon was significantly greater than that of APS charcoal. In contrast to APS charcoal, all activated carbons meet the moisture, ash, and iodine adsorption capacity standards specified in the referenced SNI. Among them, A1D300 stands out as the most effective activated carbon from oil palm fronds, exhibiting a yield of 85%, ash and moisture content of 0.9% and 7.6% respectively, and an iodine adsorption capacity of 809.2 mg g -1 .
