dc.description.abstract | Sludge generated from waste water treatment process of pulp and paper mill is a potential source of material to produce compost. It still contains a cellulose and mineral substances needed for composting. For composting in this experiment, the sludge was mixed with the rice husk in the ratio of 95:5, 85:15, and 75:25 (w/w) and added with Trichoderma viride in the concentration of 0.2% and 0.4% (v/w). The composting followed the China and Windrow methods. During composting the temperature reached 55"C after 12 days and C/N ratio decreased according to quadratic regression. In respect of the final C/N ratio obtained, composting using the China method showed a shorter time than by the Windrow method. The ratio of sludge and rice husk of 95:5 and concentration of Trichoderma viride 0.4% (w/v) resulted the best compost product for both methods. C/N ratio of 25 could be achieved in 34 days for China method and 39 days for Windrow method. The compost product fulfills the commercial compost standard. | en |
