Abstract

Water contaminationdue to the heavy metal is more widespread today. A water that has been contaminated by compounds/ions of Pbexceedingproper concentration can cause death to aquatic biota. The development of effective and efficient alternative to rehabilitate the case of heavy metal contaminant to be safe for aquatic biota is so needed. The success of aquatic plant as an agent for remediation of polluted waters has been widely demonstrated. Najas indica is a group of submerged aquatic plant that has been known to have the ability to remediate heavy metals.The aims of this research examines the relationship of concentration of lead (Pb) against survival ability of Najas indica and the effect of concentration of lead (Pb) on water pH changes and its effect on survival ability of Najas indica. This research was conducted at the Integrated Research Laboratory of postgraduate, Sriwijaya University. This research used a completely randomized design with three replications.Experimental treatment consisted of: various concentrations i.e. A0 = Without treatment, A1 = concentration of 5 mg/L, A2 = concentration of 10 mg/L and A3 = 15 mg/L. Analysis of Pb content in plants and in the water was measured on the 5th, 10th, 15th and 20th daywith AAS analysis method performed at a research laboratory in the Department of Chemistry, Faculty of Mathematics and Natural Science, Sriwijaya University. The obtained results from laboratory analysis was processed in Variant Analysis (ANOVA), if there was any significant effect, it would be continued by Duncan’s New Multiple Range Test (DNMRT) at 5% level by using statistical software 8.0 and Survival Analysis using SPSS 16.0 software. Concentration of lead (Pb) has effect on survival ability ofNajas indica.The concentration of lead (Pb) has effect on survival ability ofNajas indica. Survival ability of Najas indica with a concentration of 5 mg/L decreased to 20% until the 20th day while at a concentration of 10 mg/L and 15 mg/L decreased to 35% on the 15th day.Concentration of lead (Pb) resulted in water pH changes to be acidic so that survivalability ofNajas indica decreased. Survival ability of Najas indicaat water pH ranging of 3,00 - 5,00 and 5,01 - 7,01 more decreased when compared to the water pH ranging of 7,02 - 9,02.Najas indica has the potential in the process of remediation of lead.
