Abstract
Energy needs are increasing, but its availability is running low, so biodiesel is an alternative to renewable energy and is environmentally friendly because it is made from vegetable and animal oils. One of the potential resources as raw material for biodiesel is rambutan seeds. The process of this research was carried out using the Soxhlet Woodman method 1941. This study aimed to determine the best oil content of six types of rambutan seed that have the potential as biodiesel raw materials. The best rambutan seed oil yield is in the garuda type rambutan seeds of 36.65%, so the germplasm needs to be developed and preserved. The results of the oil test stated that rambutan seed oil had sulfur value, calorific value (HHV and LHV), and the freezing point of rambutan seed oil. While the boiling point was below the SNI biodiesel.
