This research aimed to determine the influence of adding a consortium of cellulolytic microbe, cow manure, and mixture of cellulolytic microbe and cow manure towards the composting process of garbage at the garden of the Faculty of Science and Technology Airlangga University. The independent variables used were a microbial cellulolytic consortium, cow manure, and a consortium of microbial cellulolytic and cow manure. The independent variables were the color, moisture content, pH, temperature, C-organic, N-total, and the ratio C/N. The composting technology implemented in this research was windrow composting. The difference between garbage and cow manure added was 3:1, meaning 1.5 kg cow manure for 4.5 kg garbage. For the treatment, the ratio of the addition of microbial cellulolytic consortium to garbage was 20:1, meaning 90 ml microbial cellulolytic consortium for 4.5 kg garbage. The cellulolytic microbial consortium used consisted of Bacillus sp., Lactobacillus sp., Pseudomonas sp., and Cellulomonas sp. From the Microbiology Laboratory of Biology Department at the Faculty of Science and Technology Airlangga University, as much as 20 ml/kg of garbage and 1.5 kg of cow manure for each garbage volume from the Faculty of Veterinary Medicine Airlangga University was processed. The results showed that there was a treatment effect on the composting process, which was indicated by the decrease in the ratio of C/N. The addition of cellulolytic microbial consortium is the most effective because composting can decrease C/N ratio by 80.41%.
