Abstract: Rapid expansion supercritical solution (RESS) is a technology introduced that produces a small solid oil particle with organic solvent free particle. RESS method is a better method compared to the traditional method due to many advantages such are produce clean extraction yields, obtain free solvent traces, environmental friendly and short processing time can be used in various industries such as cosmetic and pharmaceutical. Therefore, RESS technique is applied in order to produce direct solid oil particle from Luecaena leucocephala (L.leucocephala) pods instead of oil. In this study, the operating condition that applied during the RESS process in order to obtain the highest solid oil particle from the L.leucocephala pods sample are extraction temperature of 40 ºC, 45 ºC, 50 ºC, 55 ºC and 60 ºC and extraction pressure of 3000 psi, 4000 psi, 5000 psi, 6000 psi and 7000 psi at the constant extraction time of 40 minutes. The highest yield of L.leucocephala solid oil particles that obtained is about 0.65% at 60 oC and 7000 psi. The major components that obtained from the highest yield are 2,2,3-trimethyldecane, Cyclopentanone, propanoic acid and Cyclobutane, 1,2-diphenyl- by as identified by using Gas Chromatography Mass Spectrometry (GCMS).
