ABSTRACT
Research has been conducted on the effects of activation temperature variations on the characteristics and microstructure of coconut shell-based activated carbon. The purpose of this study was to determine the optimum activation temperature of coconut shell-based activated carbon and its characteristics and to observe the microstructure morphology. The activation process of coconut shell charcoal is carried out at a temperature variation of 500, 600, 700, 800, and 900 °C with a holding time of 1 hour. The results showed that the optimum activation temperature of coconut shell-based activated carbon was 700 °C. Testing in this condition resulted in 4.86% of water content, 10.84% of volatile matter content, 2.04% of ash content, and 87.12% of carbon content (based on Indonesian National Standard (SNI) No. 06-3730-1995). Morphological observations of coconut shell-based activated carbon showed that pore formation had occurred at a temperature of 900 °C.
