FITOREMEDIASI TANAH TERCEMAR LOGAM Cd DAN Pb DENGAN MENGGUNAKAN TANAMAN AKAR WANGI (Vetiveria Zizanioides)

The development of industry and mining sectors give negative impact on the environment with the presence of soil contamination due to Cd and Pb . One of the solution to overcome the contamination is phytoremediation using plant Akar Wangi (Vetiveria zizanioides). This study aims to determine the ability of Akar Wangi to absorb Cd and Pb metal in soil. \ud The experimental method was the variation of the number of Akar Wangi (no stem , 3 stems , 6 stems , 9 stems), and the variation of detention time ( 7 days , 14 days , 21 days ) . The parameter of this study was the decrease of the Cd and Pb levels in soil and in plants. Soil and plant samples were analyzed using AAS instrument . \ud The results showed that the variation in the number of plants and detention time affected the decrease levels of Cd and Pb in soil and the increase levels of Cd and Pb in plants . The highest reduction level of Cd was 35.28 ppm (61.65%) in the soil, 44.09 ppm (41.40%) in the plants in the experiment with 9 stems of plant and 21 days of detention time. The highest reduction level of Pb was 81.42 ppm (77.13%) in the soil, 357.41 ppm (71.74%) in the plants in the experiment with 9 stems of plant and 21 days of detention time
