Bagasse and sludge are solid waste of sugar industry which contained high organic material and have not been used optimally. The purpose of this research was to utilize bagas and sludge of the sugar industry through co-composting technology for making organic fertilizer and determine the influence of aeration and materials concentration on the value of C/N. Bagas and sludge combination were composted at C/N value of 30, 40, and 50. In composting process, aeration rate set on 0.4 l/minute.kg and 1.2 L/Kg of dry basis materials. The research was carried out two stages, that was preliminary research, it was determined 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
