<![CDATA[The research to assess the use of water hyacinth Eichhornia crassipes in biosorption process to remove BOD and TSS contents of laundri wastewater has been conducted. The research has 3 steps, e.i: (1) Preparation: water hyacinth cultivation in variated laundri wastewater 25%, 50% and 100% v/v, and wastewater analysis before process, e.i BOD, TSS, and pH; (2) Field test: cultivation of acclimatized water hyacinth in laundri wastewater with variation of surface coverage of 25%, 50% and 100% of total area; (3) Analysis of BOD, TSS in wastewater to account the biosorption eficiency. Results showed that water hycinth cultivation for 6 days gave the highest BOD (Biochemical Oxygen Demand) biosorption eficiency of 95,98%, which decreased from 544 mg/L to 21,85 mg/L value at total 100% area coverage. Water hyacinth also able to biosorp TSS (Total Suspended Solids) of 79,36%, which decreased from 218,00 mg/L to 44,99 mg/l value at total 100% area coverage. These BOD and TSS removals was affected by the organic metabolism and water hyacinth photosyntesis that made the laundri wastewater save for discarded to waterbody]]>
