| dc.description.abstract | Porous carbon based on red surian (Toona sinensis) leaf biomass waste was chosen as the basic material for making active carbon. Porous carbon was synthesized using the chemical activator ZnCl2 as an activating agent, by varying the molarity at 0.3, 0.5 and 0.7 to obtain optimal conditions for activated carbon. Carbon electrode sample preparation starts from the drying stage, pre-carbonization at 250 °C, grinding with mortar and ball milling, sieving using a 60 μm sieve, chemical activation of ZnCl2, printing and integrated pyrolysis in one direct stage, namely carbonization and physical activation to an optimum temperature of 850 °C in a N2 and CO2 gas environment. Next, the effects of different concentrations of ZnCl2 activator were tested, investigated, and the physical properties were compared. The results of the characterization of the physical properties of the red surian leaf activated carbon electrode were obtained by calculating the percentage shrinkage of the density value. The difference in concentration of the ZnCl2 activating agent was able to reduce the percentage density of carbon coins by 20.43%, 28.28%, and 34.31% for SM-03, SM- 05, and SM-07. Based on these results, the effect of adding the chemical activator ZnCl2 to the carbon of red surian leaves can increase the evaporation of impurity elements other than carbon which is indicated by an increase in the shrinkage value. | en_US |
