This study aims to determine the effect of concentration of sodium carbonate (Na2CO3) on the quality of activated carbon produced from sugarcane bagasse. The study utilized a non-factorial Completely Randomized Design (CRD) with treatment variations of sodium carbonate concentrations consisting of five levels: A1 = Na2CO3 4,5%, A2 = Na2CO3 5,0%, A3 = Na2CO3 5,5%, A4 = Na2CO3 6,0%, and A5 = Na2C…
