Abstract
Various studies have found the presence of heavy metal contamination in Kendari bay. Heavy metals can have implications for the health of residents living around Kendari Bay. Therefore, it is necessary to do seawater treatment to reduce the heavy metal content. The objective of this study is to reduce the heavy metal content of Plumbum (Pb) and Chromium (Cr) in seawater. The study employed quasi-experimental Nonequivalent Control Group Design. This study tested the decrease in the levels of heavy metals Plumbum (Pb) and Chromium (Cr) using the Atomic Absorption Spectrophotometry (AAS) method after flowing in the Montmorillonite medium. The results showed the highest decrease in Pb and Cr levels with variation in elevation of 80 cm using Montmorillonite and 100 minutes, each of them is 41% and 50%. The results of data analysis for Pb Level using the One Way ANOVA test obtained p-value values (0.000) <α (0.05), Cr levels obtained p-value value (0.000) <α (0.05). The concentration of seawater tested has decreased the strength of heavy metals after flowing through the medium of Montmorillonite. It should be noted that the decrease in salinity so that water can be used in fulfilling the daily needs of the community.
