Abstract. The decomposition of organic matter on leaf litter substrat runs very slowly in nature
resulting in the accumulation of litter in the ecosystem and has even become an organic waste
that creates many problems. The research dealt with the use of lignocellulolytic fungi inoculum
consisting of 3 isolates: Aspergillus fumigatus (cellulolytic), A. tubingensis (xylanolytic) and
Geotrichium sp (ligninolytic) as a starter of leaf litter composting. The purpose of the study is to
understand the pattern of humic-fulvat acid and C/N ratio on the process of composting of leaf
litter with the addition of inoculum. Observations were made to the chemical changes of compost
for 3, 6 and 9 weeks of composting and the data were analyzed in RM-ANOVA (Repeated Measures of ANOVA). The result shows that the best pattern of humic acid and fulvic change from the
initial to final composting occurs at the Geotrichum spinoculum of 0.60 or 105.2% and for fulvic
are of 0.55 or 56.1% of baseline. The highest ratio value of CHA/CFA at the end of observation
was by consortium of A. fumigatus and A. tubingensis inoculums that was 2.94 and the lowest
value was at commercial inoculum that was 0.80; and the sharpest change value also occurred
in the consortium A. fumigatus and A. tubingensis inoculums of 2.20 or 297.3%. Therefore, the consortium isolates were capable of causing the maturity of the compost most rapidly compared
to other isolates.
