| dc.description.abstract | Water hyacinth (Eichhornia crassipes) is known as the fastest growing aquatic weed, which is available almost year–round in the tropics and subtropics. It represents a potential candidate for wastewater treatment as well as soil conditioner because of their ability to absorb nutrients. Based on this characteristic, water hyacinth was suggested to the main material to transfer nutrients from wastewater to soil under composted and fresh forms. Experiments using water hyacinth to absorb nutrient from the water were performed for 14 days with aeration and non-aeration trials at various nitrogen and phosphorous concentration. Composting process was carried out within 19 days with fresh, dry and acid-pretreated water hyacinth and fresh vegetables to compare the composting potential between them. In addition, the final experiment used fresh water hyacinth mixed with soil to assess the ability to provide direct nutrients in the fresh form of the water hyacinth. Absorbing and composting potential of end product would be evaluated based on the determined parameters such as pH, total nitrogen, total phosphorus measured during the initial and final period of the study. After treatment, the ability to remove nitrogen seemed too small to be seen while the removal of phosphorus was visible. The ability to make compost as well as provide nutrients for the soil of the water hyacinth was noticeable but not completely yet.
