Abstract
The Lapindo mud disaster is a disaster in the form of a mudflow originating from a mudflow in the Porong area, Sidoarjo. This overflow has occurred since 2006 until now. This disaster brought several new problems, one of which was soil and water pollution due to metal content absorbed by soil sediments. One type of metal found in the land around the Lapindo mud area is iron (Fe) and copper (Cu). These metals can be reduced by chemical-biological methods or by combining phytoremediation with the addition of humic acid. The research was carried out from March – October 2023 with soil samples taken in Glagaharum Village, Porong District, Sidoarjo Regency. The research was carried out by implementing a Factorial Completely Randomized Design (CRD) experimental design. The first factor is the addition of humic acid, namely H0: without humic acid and H1: Humic acid at a dose of 600 ppm and the second factor is the type of hyperaccumulator plant using grass and weeds with treatment R0: Without plants; R1: Vetiver plants; R2: Pennisetum grass plants; R3: cyperus plant; and R4: Centella asiatica. This experiment had 10 treatment combinations with each treatment repeated 3 times. Thus, a total of 30 polybag treatment samples were obtained. Observation data were analyzed using analysis of variance (ANOVA). If there is a real effect of the treatment, a further test is needed, namely the BNJ (Honestly Significant Difference) test at the 5% level to determine the difference between the treatments. Based on researchas been carried out, it is found that pegagan plant (Centella asiatica) in soil media with the addition of humic acid is able to translocate total Fe metal in plant tissue which is divided into the root part of 14500 ppm and the crown part of 7933 ppm or the equivalent of 55.75%. Meanwhile, gotu kola plants grown in media without the addition of humic acid were able to translocate Cu metal to plant tissue which was divided into the root portion of 63.37 ppm and the crown portion of 32.17 ppm or the equivalent of 71.44%.
