Abstract

In urban communities, waste produced by each household as part of everyday life. As soon as that happens on campus UPN "Veteran" East Java. However, the garbage that dominates the campus environment is the dry leaf litter, along with the campus greening program. Dry leaf litter on campus UPN "Veteran" East Java processed as compost which will be used to meet the needs of the entire campus UPN "Veteran" East Java. The purpose of this experiment was to determine the maturity of composted cow manure with the addition of variations in aeration processes manually and mechanically. The material used in this study are rubbish campus UPN "Veteran" East Java and cow dung. The variables used in this study is the sampling time of 0, 14, 21, and 28 days, the oxygen demand and the number of cow dung is used. In this study the tested parameter is N, C, C / N ratio and pH. This study uses a batch system. From these results, the best composting reactor obtained at 8 with the addition of cow manure 8.23 kg and 24 kg of waste campus with mechanical aeration process, and the ratio of C / N 12. While in the process of manually aeration, compost best at reactor 4 with the addition of 8.23 kg of cow dung and 24 kg of waste campus with C / N ratio 16.6. Key Word : domestic waste, composting, aeration
