In advanced countries, sludge gener

In advanced countries, sludge generated from wastewater treatment systems are used as raw materials for composting process became a new direction, towards sustainable development. However, in our country there is no sewage sludge effective solutions, mostly in landfills. Besides a type of aquatic plants present concern is hyacinth, it reproduces rapidly in the aquatic environment. The problems caused by water hyacinth has been damaging to the environment and humans. Also, sawdust from wood processing mills also caused serious environmental pollution. There have been many studies on the treatment of waste and not effective. So research on composting of sewage sludge is mixed with water hyacinth direction has brought economic benefits, a contribution to environmental protection.
Thread performed in laboratory scale with the input of the process is the water hyacinth compost, sludge and sawdust by aerobic composting methods in wooden barrels. Research projects aimed at finding the optimal mix ratio and compost quality accreditation by the chemical and physical experiments finally checked by means of evaluating the germination and the growth of vegetable seeds in distribution of finished products.
The paper consists of two experiments. Experiment 1 conducted within 45 days based on the formula 3 with a mixing ratio of water hyacinth and mud and sawdust different to find the optimum mix ratio. Each recipe is aged in barrels to compare the two. The results of the two barrels brewed the same formula rate equal criteria and formula 1 (CT1) (60% + 35% sewage sludge hyacinth sawdust + 5%) had the best results compared to 2 compost bins and the remaining 37.24% C 1.23% of the total N, 2.47% P. Then proceed to verify crop quality compost. The results also show CT1 for better quality fertilizer.
