description: Biodiesel is an alternative fuel from renewable sources derived from vegetable oil, one of which is used cooking oil and can be synthesized through a transesterification reaction using a heterogeneous alkaline catalyst. The purpose of this research is to obtain a heterogeneous catalyst for banana peel, to determine the optimal conditions for biodiesel synthesis from used cooking oil with a heterogeneous catalyst for banana peel, to determine the quality of biodiesel products by testing physical properties and chemical properties, and to obtain biodiesel products in accordance with SNI 7182:2015. The research was carried out by calcining the peel of the kepok banana with a furnace at a temperature of 550 and 600. Then the transesterification reaction was carried out by reacting to methanol and catalyst with a concentration of 2% and 3% concentrations to a temperature of 60 for one hour and inserting used cooking oil with a molar ratio of 1:6 and then reacted for 1, 2, and 3 hours. Catalysts were analyzed using FTIR, XRD, SEM-EDX, and BET methods. Biodiesel was analyzed for density, viscosity, yield, flash ℃℃℃point, cetane number, and GC-MS. Produced a heterogeneous catalyst of kepok banana peel with high potassium content, white powder form, with the best operating conditions of biodiesel synthesis at calcination temperature variation of 600℃, reaction time of 3 hours, and a catalyst concentration of 3% with a biodiesel yield of 98.56%, and the resulting biodiesel has met the parameters of SNI 7182:2015.
