Abstract
This study is focused on the process of vermicompost in composting leaf litter and paper. This study carried out by using earthworm (American Night Crawler) as the independence variable. Meanwhile, paper and leaf litter are dependence variable. It scarried out in 5 weeks. The vermicomposting performance in temperature, pH and moisture content shows that the range of optimum temperature is between 25ºC to 28ºC, pH were observed to be neutral to slightly acidic (pH 7.8 to pH 5.7) and moisture content were observed to be high ranging from 61.36% to 89.98%. In microbial population, fungi shows highest microbial population (1.4x10�), followed by actinomycetes (1.3x10�) and bacteria (0.2x10�) presence in the vermicompost materials. The nutrients in vermicompost of leaf litter and paper are respectively, nitrate nitrogen ranging from 3.5 to 6.6 per 20g sample, analytical urea ranging from 115.66 to 135.4 per 20g sample, and ammonial nitrogen is ranging from 2.2 to 2.4 per 20g sample. Meanwhile, for C:N ratio is 1:20 to 1:24. The value of each nutrients and C:N ratio is influenced by types of treatment applied.
