Bioethanol from Rimau Gerga Lebong (RGL) orange waste is one of the solution to overcome fuel oil problem. The aim of this research is to get the type of microorganisms and fermentation time that produce the highest ethanol from RGL orange waste. The research method used was Randomized Block Design (RBD) of two factors, namely type of microorganisms (Trichoderma viride, Saccharomyces cerevisiae, and Trichoderma viride + Saccharomyces cerevisiae) and fermentation time (3 days, 5 days, and 7 days. Within the three type of microorganisms with variations of fermentation time showed that the pH was able to carry out the fermentation process smoothly. The highest total dissolved solids were in the type of Trichoderma viride 3 days and 5 days, and the type of mix of microorganisms on the 3rd day. The highest ethanol content is in the type of Sachharomyces cerevisiae for 7 days. ANOVA result showed that the interaction between two treatments on the total dissolved solids experienced significant differences, so it continue with the DMRT test at a significant level of 0.5%. However, it is different from the results of ANOVA on ethanol content which showed that there were significant differences between ethanol content and types of microorganisms, but there was no significant difference on fermentation time
