Palm Oil Mill Effluent (POME) is a organic residue that is generated by palm oil mills during the process of extracting palm oil from fresh fruit bunches of oil palm. Anaerobic digestion can be used for the treatment of POME to reduced organic content and generated some substances, such as volatile acids, alcohol, methane gas, etc. During anaerobic fermentation process, microorganism requires the presence of trace elements to improve their performance. This research will be carried out as a study of the presence of trace elements, such as metals (Cu, Mn, <br /> <br /> <br /> <br /> and Mg) that had significant effects on ethanol formation. Circulating Bed Reactor was used and operated in a batch system for 48 hours. Metal ions were screened and analyzed by using twolevel factorial design method with level (1) (had significant effect) and level 0 (had no significant <br /> <br /> <br /> <br /> effect) respectively on ethanol formation. The value of F and Ftable was compared using the stastitical tests at a significance level of 5% and 1% with the following hypotheses: H0 fail to reject (had no significant effect) if the significance of F<Ftable and H0 reject (had a significant effect) if the significance of F>Ftable. Mn2+ and Cu2+, Mg2+ combination were screened as the significant variable which had positive effects on ethanol formation from POME at a significance level of 5% and 1%. The result from this study have identified the metal ions which had significant effect as a foundation for optimization ethanol formation.
