This study aimed to determine the effectiveness of the kiambang plant (Salvinia molesta) in reducing copper (Cu) heavy metal concentrations in water bodies through phytoremediation. Copper concentrations of 3 ppm, 6 ppm, 9 ppm, 12 ppm, and 15 ppm were applied, and observations were conducted over seven days using a UV-Vis spectrophotometer at a wavelength of 445 nm. The results showed a significant effect of Cu concentration variation on the plant’s phytoremediation capacity, as indicated by the One Way ANOVA test (F-count 73.064 > F-table 3.05; p < 0.05). The highest remediation efficiency was observed at the 15 ppm concentration. Kiambang plants proved effective as phytoremediation agents in mitigating copper heavy metal pollution in aquatic environments.
