However, the production of biodiesel from edible oil has provoked the food versus fuel dispute. Thus, a non-edible crop, Annona muricata, is selected as the raw material to produce oil for biodiesel production. In this study, A. muricata oil was extracted with n-hexane at 70 {\^A}oC for 6 h. Subsequently, the oil was transesterified with methanol and potassium hydroxide (KOH) to produce biodiesel. The significance of transesterification parameters including temperature, time, catalyst concentration, and oil-To-methanol ratio on biodiesel yield () was established through two-level factorial design. The factorial design shows that all parameters are significant. Besides, the high content of monounsaturated fatty acid (oleic acid) in the resultant biodiesel suggests that A. muricata biodiesel could display good fuel quality. This hypothesis is proven by the excellent calorific value (39.21 MJ kg-1). {\^A}{\copyright} The Authors, published by EDP Sciences, 2019.}, issn = {25550403} }
