Utilization of Used Cooking Oil as a Raw Material for Biodiesel: A Step Towards Renewable Energy
Main Article Content
Abstract
Used cooking oil, a waste product from the frying process, holds significant potential as an economical and environmentally friendly raw material for biodiesel. This study aims to explore the effect of NaOH catalyst concentration on the transesterification process of used cooking oil in producing biodiesel that meets the Indonesian National Standard (SNI). The research methodology includes the characterization of used cooking oil, variation in catalyst concentration (0.75%, 1%, 1.25%, and 1.5%), and analysis of biodiesel quality, covering yield, viscosity, density, and free fatty acid (FFA) content. The results indicate that a NaOH catalyst concentration of 0.75% produces the highest biodiesel yield (73.9%) and meets the quality parameters in accordance with SNI. This study makes a significant contribution to the development of biodiesel as a renewable energy source in Indonesia.
