This study aims to determine the effect of variations in the activation temperature on the quality of activated carbon palm bunches using proximate and ultimate analysis. In this research, the process of preparation activated carbon palm bunches with three stages in the process of dehydration, carbonization, and activation. The activation process uses temperatures of 6000C, 6500C, 7000C, 7500C, 8000C with a time of 30 minutes, After activation, the sample is analyzed using proximate and ultimate analysis methods, Proximate analysis is an analysis to determine the content of water, ash, volatile substances and carbon bonded ultimate analysis is an analysis to determine the content of the elements carbon, hydrogen, nitrogen, oxygen, and sulfur. Proximate analysis methods use furnace equipment, ovens, and scales, while ultimate analysis uses CHN-2000 analyzers and SC-632 analyzers. Proximate analysis results show that the water content, volatile matter content, and ash content of activated carbon bunches with proximate analysis have decreased from the activation temperature 6000C-7000C, then increases the activation temperature 8000C, whereas carbon bound has increased from the sample activation temperature 6000C-7000C then decreases in temperature 8000C while the results of the ultimate analysis show that all samples have variable elemental content, the element carbon increases with increasing temperature of activation while the elemental content of hydrogen, oxygen, nitrogen, and sulfur decreases with increasing temperature of activation. So, for all conditions of the activation temperature, at a temperature of 700 ° C has the optimum value with the highest carbon content and meets the Indonesian National Standard (SNI) quality of activated carbon.
