The Data obtained is analyzed using two-lane analysis (Two Way Anova). Based on the results of the analysis of the treatment EM-4 and the old incubation against the liquid waste stamp batikobtained the following results: At a group of doses acquired F count = 4209.382 > F table 5% = 3.55, then H0 rejected or there is a real influence of various doses of EM -4 which is used against COD levels. At the time group gained F count = 77.756 > F table 5% = 3.55, then concluded that there is a real influence of incubation time against the rate of COD waste car stamp batik.
