Durian, a widely consumed fruit in Indonesia, produces substantial peel waste during the harvest season, contributing to environmental problems due to its strong odor and rapid decay. Notably, durian peel contains approximately 57.42% carbon, making it a promising raw material for activated carbon production. Activated carbon is a porous adsorbent, typically composed of 85–95% carbon, and available in granular, pellet, or powdered form. This study investigates the effect of activator type on the characteristics of activated carbon derived from durian peel waste, aiming to identify the optimal activator. The research was conducted at the Environmental Physics Laboratory of the State Polytechnic of Cilacap, using potassium hydroxide (KOH) as the chemical activator. The activated carbon was evaluated based on moisture content, ash content, and iodine absorption capacity. The results indicated a moisture content of 1.62%, ash content of 6.9%, and iodine absorption of 1186.5 mg/g. These values meet the Indonesian National Standard (SNI 06-3730-1995) for high-quality activated carbon. The findings suggest that the use of alkaline activators such as KOH significantly influences the carbon’s pore structure and overall quality. The produced activated carbon demonstrates potential for various applications, particularly in adsorption processes, owing to its high surface area and favorable physicochemical properties. This study supports the valorization of durian peel waste into valuable environmental remediation materials, contributing to both waste reduction and sustainable resource utilization.
