Synthesis of carbon electrode of supercapasitor has been done based on candle banana peel with carbonization temperature varied at 500oC, 600oC, 700oC and 800oC with each sample code of S5, S6, S7 and S8. Green carbon paper sample of banana peel was carbonized at a furnace with N2 irrigated by using multilevel warming temperature profile of 285oC and it was holded for 1 hour, then proceed to th…
