Abstract
Research on the phytostabilization of mercury in Ipomoea reptans Poir plants has been done. This study aims to determine the effect of planting age on the ability of mercury uptake by leaves of Ipomoea reptans Poir, knowing the mercury concentrations distributed on the leaves of Ipomoea reptans Poir and determine the ability of Ipomoea reptans Poir plants as mercury hyperaccumulators. Planting age used in this study consisted of four times, namely: 2, 3, 4 and 5 weeks. The concentration of planting media used is 25 ppm, 50 ppm, 75 ppm and 100 ppm. The results of the analysis showed that the maximum absorption time occurred in the third week with absorption concentrations of 145.484 µg / gr dry weight, and that value was an indicator that Ipomoea reptans Poir was a mercury hyperaccumulator.
