Co-Composting Process Of Bagasse And Sludge From Sugarcane Industry With Influence Of Difference Initial C/N Value And Aeration

Abstract

The purpose of this research was to utilize bagasse and sludge of the sugarcane industry through cocomposting processes for producing compost and determine the influence of aeration and C/N ratio. In composting process, bagasse and sludge combination were composted at C/N value of 30, 40, and 50 and aeration flow rate were set on 0.4 l/minutes.kg and 1.2 l/minutes.kg. The research was carried out two stages, that was preliminary research to determine the composition of raw materials mixture, and primary research for determining C/N value during composting. Parameters monitored during composting were temperature done every day, pH and C/N determined every week. The result showed that aeration treatment did not give noticeable effect on C/N value and compost with initial C/N value of 30 gave the fastest decomposition process in co-composting stages.
