Tempe industry is widely developed in the territory of Indonesia because generally with a small scale household industry using relatively cheap and fairly simple production technology, the process uses water from the initial stage to tempe packaging. The problem of tempeh industry waste is directly discharged into the river without prior treatment so that it can affect water quality. As a result, there is an unpleasant odor and environmental imbalance both physically, chemically and biologically from waters that receive daily waste loads from the tempe production process, river water is polluted and disturbs the life of organisms in the waters. The purpose of this study was to treat the liquid waste of the tempe industry using anaerobic biofilter media tile fragments and ceramic fragments to repair COD, BOD, TSS, TDS and pH levels according to quality standards. This type of research is a pseudo-experiment with the design “Pre Test – Post Test With Control Group Design”. The results of anaerobic biofilter treatment of tile media repair COD levels 35.60%, BOD 22.83%, TSS 38.21%, TDS 37.61% and pH 17.40%. Ceramic media anaerobic biofilter processing results repair COD levels 31.38%, BOD 2.33%, TSS 31.23%, TDS 35% and pH 13.64%. The conclusion of this study is that processing using anaerobic biofilter media tile fragments and ceramics fragments can repair COD, BOD, TSS and pH levels of tempe liquid waste but not yet according to quality standards, but processing using anaerobic biofilter media tile fragments and ceramics fragments can repair TDS levels of tempeh liquid waste according to quality standards.
