Abstract

Synthesis of activated carbon from ketaping fruit shell biomass aims to produce high-quality active carbon to be applied in various fields. Activated carbon from ketaping fruit shells is synthesized by thermal treatment. It is synthesized through two stages, namely carbonation and activation. The carbonation stage is carried out at 400^oC under O₂ gas flow. This aims to break down lignol cellulose into carbon with low-quality pores through incomplete combustion. The activation stage is carried out by mixing activated carbon and KOH in varying ratios of 1:1, 1:3 and 1:5 wt. It is carried out by multilevel thermal treatment at 700^oC for 3.5 hours to form activated carbon with high pore quality. The activated carbon produced is then subjected to EDS characterization to see the active carbon content and XRD to see the structure of the active carbon with the characteristics of distance between layers, layer height, layer width, and number of layers. The results of EDX analysis show that the active carbon from the shell of the ketaping fruit contains 97.52% carbon and 2.48% oxygen. The results of XRD analysis show that the activated carbon surface area optimum at a molar ratio of 1:3 wt is 1,708.62 mg^-1. The distance of the resulting activated carbon layer is 0.3566nm at the 002 peak and 0.2102nm at the 100 peak. The layer height and width of the active carbon layer produced at a 1:3 wt ratio were 0.5489nm and 0.3002nm. Meanwhile, the number of layers of active carbon produced is 3 layers.
