<br/><br/> Palm pressed fiber (PPF) is the solid waste produced from palm oil milling company after the pressing process. Recovery of oil and reuse of the palm pressed fiber is a great opportunity for cost saving in the oil processing industry. The objective of the research is to recover residual oil which still left in the PPF by using ultrasonic-assisted extraction method (UAE). The process is carried out by priory drying process of the PPF at 60 °C for 1 hour. Then the dried sample will undergo the extraction process in the ultrasonic bath by using methanol as a solvent. The effect of solid: liquid ratio and extraction time are varies in the range of (1:3-1:8) and (0 minutes-60 minutes) respectively. Yield of the extracted oil are measured for all conditions. Results from studies shows that the highest yield is 12.90% which obtained at the condition 1:5 (g/ml) of the solid: liquid ratio and 30 minutes of the extraction time. Hence, the result from Gas chromatography-mass spectrometry (GC-MS) has confirmed that the properties of the extracted oil are almost similar to the crude palm oil (CPO)
