Abstract

Durian peel is one of the agricultural wastes that has not been utilised optimally and has the potential to be used as an alternative to biomass-based activated carbon. This study was conducted to study the optimisation process of making activated carbon from durian peel using H3PO4 activator. The optimisation process was carried out using Response Surface Methodology (RSM) to optimise the variables that affect the quality of activated carbon using the Box-Behnken method. The variables used were 20% v/v, 25% v/v, and 30% v/v H3PO4 concentrations, activation time of 12 hours, 24 hours, and 36 hours, weight ratio of activated carbon to H3PO4 activator 1:2 m/v, 1:3 m/v, and 1:4 m/v. The optimization using RSM method results showed an iodine absorption capacity of 790.139 mg/g obtained under the following conditions, H3PO4 concentration of 30% v/v, activation time of 34.78 hours, and weight ratio of activated carbon to H3PO4 activator of 1:4 m/v. Activated carbon from durian peel with optimum conditions obtained surface area value of 2.407 × 10-11 m2 and activated carbon diameter of 4.878 μm using Scanning Electron Microscopy (SEM) analysis test

Abstract

The increasing global energy demand and environmental concerns necessitate the development of alternative energy sources. Durian peel, an abundant agricultural waste in Indonesia, presents significant potential for bio-briquette production due to its high cellulose and lignin content. This study investigates the effect of carbonization temperature on the quality of durian peel-based bio-briquettes. Carbonization was conducted at 300°C, 400°C, 500°C, and 600°C, with proximate analysis and calorific value determination performed according to SNI 01-6235-2000 standards. The results demonstrate that higher carbonization temperatures reduce moisture and volatile matter while increasing fixed carbon and calorific value. At 500°C, the bio-briquettes exhibited optimal properties, including moisture content (7.47%), volatile matter (13.54%), and a calorific value exceeding 5000 cal/g, meeting the SNI standard. However, ash content at this temperature (9.33%) slightly exceeded the standard (≤8%), highlighting a trade-off between energy efficiency and residual minerals. This study concludes that 500°C is the optimal carbonization temperature for producing high-quality bio-briquettes from durian peel, balancing energy output and combustion efficiency. Further optimization of the process is recommended to enhance fixed carbon content and minimize ash. These findings contribute to sustainable energy practices by transforming agricultural waste into a renewable energy resource, addressing both waste management and energy challenges.
