Abstract
Detergent serves as the most widely used cleaner, one of the ingredients for detergent is phosphate. Excessive phosphate in the waters will cause eutrophication and endanger the aquatic biota in it. Therefore, a solution is needed to reduce phosphate in the waters; one such way is by using Eichornia crassipes (Mart.) Solms and Marsilea crenata C. Presl. The purpose of this study was to determine the effect of plant species and phytoremediation time on phosphate levels in laundry waste. The variables studied were variations in plant species and phytoremediation time. In the plant variety, water hyacinth, water clover, and a combination of the two are used. In the variation of time used 0, 48 and 96 hours. The waste used is waste from a laundry business in Wonokromo, Surabaya. Parameters tested include phosphate, DO, BOD, pH, temperature, and turbidity. The exploration stage is in the form of acclimatisation and range finding tests to determine the concentration of wastewater used in the experimental stage. The results showed that plant species and phytoremediation time affected the decrease in phosphate levels. The correlation between phytoremediation time on parameters of phosphate levels, BOD, and pH will decrease with the duration of phytoremediation, but DO parameters will increase with the duration of phytoremediation.
