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.
