Abstract: This study examined the phytoremediation capacity of upland kangkong (Ipomoea reptans Poir) in a hydroponic system with elevated levels of lead (Pb). This study aimed to determine the concentration of Pb absorbed by I. reptans Poir and the time required for absorption, as well as to compare the absorbed concentration with the WHO tolerable daily intake for humans. To conduct the study, I. reptans Poir seeds were germinated in perforated cups containing charcoal and immersed in a hydroponic system filled with water and nutrients. The plants were exposed to the lead-induced hydroponic system for 10, 20, and 30 days. The concentration of absorbed Pb was analyzed using ICP-OES. The results revealed that Pb was not detected in the plants exposed for 10–20 days. However, detection began after 30 days, with the amount of Pb being
