The existence of organic waste becomes an urban problem. The objective of the study is to develop composting techniques made from raw urban organic waste carried out massively. The research consists of two factorials; the treatment of factor I is the mixture of EM4 and urea, and factor II is the portion of market waste in the mixture of organic matter of dry and wastewater waste consisted of 0%, 20%, 40%, and 60%. The result of the study shows that there were biomass volume decline in the range of 25-70% and the change of pH which ran above 8 and after five weeks it was relatively stable under normal condition around 7. Moreover, there was high temperature change ranged from 40-500C and after six weeks it was stable of 35-400C. The discoloration also happened from the green fresh leaves or dry brown leaves turned to darkish brown. Based on the C/N ratio change indicator, the mixed treatment of 20%, 40%, and 60% with the addition of EM4 starter and urea biomass has been composted at week 8 (for fifty days in fresh condition) and it can be used as a reference for the preparation of appropriate technology for mass composting. Keywords: dry leaf litter, wet garbage, mass composting
