This study aims to determine the structure of morphology and functional groups from activated charcoal for palm oil waste with variations in activation temperature. The process of two stages: the carbonation and activation stage. Carbonation process using a pyrolysis reactor at a carbonation temperature of 200oC -400oC for 6 hours. Then, the sample activated at a temperature of 700 °C, 750oC, 800oC, and 850 °C. Samples were characterization using SEM and FTIR. SEM analysis results show the largest pore size at a temperature of 850 oC with a diameter of 48.3 nm, and the lowest temperature was 700 °C with a capacity of 35.3 nm. Activated charcoal from oil palm shell waste at mesopore size. Next, FTIR analysis results show wave numbers 2165,18 cm-1, 1554 cm-1, 1030,76 cm-1 dan 424,11 cm-1.  The removal of some absorption bands and  the formation of new absorption bands, caused by the activation temperature
