Abstract
Cinangka Village has been the center of the accu smelting industry since 1980. This has resulted in soil contamination. The purpose of this study is Analyzing the effectiveness of Ornamental plant (Cordyline fruicosa) and Land cress (Ipomea reptans Poir) in reducing Pb on the soil. The method used for sampling is purposive sampling. The parameters tested were total Pb in soil and % Pb in plants also the dry weight of the plants. The effectiveness of the plants is known by calculating the difference of total Pb in soil with total Pb absorbed from plants divided with total Pb in soil and multiplied it with 100%. The experiment were using Ornamental plant (Cordyline fruicosa) and Land cress (Ipomea reptans Poir) within 24 and 36 days to remediate the soil with 157,82 ppm and 10032,84 ppm Pb. The highest level effectiveness of lead phytoremediation with plants was with Land cress with an average of 0,994% within 24 days of Pb polluted soil of 157.82 ppm. The effectiveness of lead phytoremediation with the lowest plants was Ornamental plant with an average of 0.945% within 36 days in Pb polluted soil of 10032,84 ppm. The Effectiveness of phytoremediation treatment with Orrnamental plant and Land cress in one harvesting is not effective (Less than 1%) in reducing lead concentration in the soil.
