waste that has a negative impact on the environment. Metal’s concentration in soil can be reduced by planting metal binding (hyperaccumulator plants) through the phytoremediation process. This study aims to analyze differences in growth of kale (Ipomoea reptans P.) which is planted on soil contaminated with metal mercury (Hg) at various compost doses; analyze the effectiveness of metal mercury (Hg) uptake by kale (Ipomoea reptans P.) at various compost doses. The design used was a completely randomized design (RAL) with 3 treatments and 6 replications. The data from the research result in the from of high growth rate, leaf number growth rate, root length, root dry weight and crowns were analyzed statistically by one-way ANOVA test with a confidence level of 95% (p< 0,05) if there is a difference then it is analyzed using the lest LSD, while the parameters of root proportion, RAR, RLD, and metal absorption effectiveness (IBR and FT) were analyzed descriptively, The design used was a completely randomized design (RAL) with 3 treatments and 6 replication. The result showed compost treatment 0 ton/ha, 5 ton/ha, dan 10 ton/ha all three differ in the parameters of plant height growth rate, leaf number growth rate, root length, root dry weight, shoot dry weight, Root Length Density (RLD), Root Area Rasio (RAR), and root proportion. Compost treatment of 10 ton/ha showed the greatest value of all parameters compared to other treatment. The effectiveness of kale plants with the addition of compost 0 ton/ha; 5 ton/ha; and 10 ton/ha in reducing levels of mercury (Hg) as seen from the value of the bioremediation index, respectively 99,8%; 99,82; and 99, 85%; and the value of transfer factors, respectively 0,90; 1,12; and 1,97 so that compost ratio that most effective the effectiveness of kale plants is 10 ton/ha.
