Biodiesel is one of the best available resources that have come to the forefront recently. Malaysia has an abundance of agricultural waste which can be tapped as one of the biodiesel resources. This study aimed at evaluating the appropriate Techniques of drying the plant seeds from the agricultural waste in terms of quantity extract of the oils from seed by using Soxhlet with solvent n-hexane, we compared biodiesel potential between seed oil extracted from Mango kernel (Mangifera indica), Rambutan (Nephelium lappaceum),Pumpkin (Cucurbita ps) and Papaya (Carica Papaya. L). we examined the oil physicochemical properties. In order to establish an optimum condition for the production of biodiesel, parameters such as catalyst loading, reaction temperature, methanol to oil molar ratio were studied. The results analyzed revealed that the transesterification of the Nephelium Lappaceu oil, the condition of the optimum reaction was found to be 65oC reaction temperature, 12:1 molar ratio of methanol to oil, 2.0% catalyst (w/w) and an hour reaction time. The optimum reaction conditions for Cucurbita oil were also found to be 65oC reaction temperature, 12:1 molar ratio of methanol to oil, 2.0% catalyst (w/w) and reaction time of 1hr. These conditions gave an ester (Cucurbita spoil methyl ester) yield of 96.81% by weight; it is the best yield from between the study oils. The properties of biodiesel have characterized the results were found to satisfy a standard of EN14214 and ASTM D6751.The research findings marked all seed oils in this paper as a promising resource for biodiesel production.
