Abstract

Research on the ability of plants to reduce and transport pollutants, especially heavy metals, remain advancing to date in line with current technological developments. The purpose of this study was to investigate the effect of leachate concentration on the number of tillers of Typha latifolia plants. It also investigated the leaf length and number of leaf petals of these plants. The materials used in this study included liquid/leachate media sourced from a landfill in Banda Aceh, the aquatic plants of Typha latifolia (torch), and heavy metals such as chromium (Cr), mercury (Hg), and lead (Pb). The results showed that the increase in Typha latifolia plant roots occurred at leachate concentration of 20%, 40%, and 60% for sources of 4 cm, 2 cm, and 1 cm. Meanwhile, the leaf length was observed in the leachate concentrations of 20%, 40%, and 60%, resulting in enhancers of 6 cm, 1 cm and 1 cm. Besides, increments of leaf number occurred at leachate concentrations of 20% and 40%, yielding as much as 1 and one leaves on the 2nd and 4th week. The overall results of the study showed an increase in low concentrations.
