Abstract
This study aimed to examine the potential of banana peel ash calcined at temperatures of 500 °C, 600 °C, and 700 °C for 4, 5, and 6 h to be utilized as a heterogeneous base catalyst in transesterification reactions to convert triglycerides into methyl esters. X-Ray Diffraction was utilized to ascertain the crystalline phase of the prepared catalyst, whereas Fourier Transform Infra-Red was used to identify the functional groups. The experimental results showed that the optimum parameter conditions were achieved at a calcination temperature of 700 °C for 4 h, with a biodiesel yield of 98.06%. Furthermore, based on the FT-IR analysis, the most significant functional group of the catalyst was from alkaline earth metal oxides. This was also confirmed by the XRD analysis, which showed that K2O compounds have the potential as green catalysts for future use.
