Abstract: Sugarcane mill produces significant amount of wastes mainly in the form of liquid waste or also knows as sugarcane mill effluent (SCME). SCME can cause water pollution and need proper treatment before it can be discharge into water sources (river or lake). This is due to the high content of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solid (TSS) and Volatile Suspended Solid (VSS).In present study, biological treatment (anaerobic system) and membrane filtration assisted with ultrasonic effect was carried out to treat the SCME. In anaerobic system, the decomposition of organic and inorganic substrate occurs without the presence of oxygen to treat high concentration of organic carbon waste such as SCME and methane gas (CH4) is produced as a by product in this process. Ultrasonic assisted membrane system is applied in the system in order to enhance the efficiency of the process in treating the SCME. Study was conducted by comparing the quality of the SCME after undergo the treatment process using membrane anaerobic system (MAS) and ultrasonic membrane anaerobic system (UMAS). From the study, it shows that more than 90% (>90%) percents of removal efficiency (BOD, COD, and TSS), and reduce flux decline is achieved by using UMAS
