This study aims to determine the role of water hyacinth leaves powder on wastewater adsorbed from Cu ion, which is one of the metals responsible for environmental pollution and analyzed using AAS. Cu-wastewater was conducted in bathes and used to optimized the sorption at 250 ml, with 10 grams of water hyacinth leaves adsorbents added at speeds of 100, 150, 200 rpm, with contact times arrangement of 30, 60, 90 minutes. A maximum adsorption rate of 10 grams at a maximum speed of 100rpm, led to a removal efficiency of 98.19% and 60 minutes contact time. The equilibrium data utilized was properly represented in the Freundlich adsorption isotherm model to analyze the mechanism using R2≈1. In addition, Cu adsorption kinetic models were analyzed using the pseudo-second-order model at an adsorption rate of R2≈1. The result showed that the Cu-wastewater used to activate the water hyacinth leaves powder was highly effective for the treatment.
