Heavy Metal Uptake Test by Aquatic Plants Tissue Culture Products with Neutron Activation Analysis in Ciliwung River

Abstract

High levels of human activity and the amount of waste generated from these activities often end up in rivers. One of the largest and longest rivers in the Jakarta and West Java regions is the Ciliwung River. The purpose of this study was to test the phytoremediation ability of 5 types of aquatic plants propagated through tissue culture (Bacopa sp., Eichornia diversifolia, Althenanthera reinicky, Ludwigia sp, and Murdannia, sp.). The research method used was tissue culture water plants to be tested in an aquarium filled with water collected from the Ciliwung River for 1 month, and the water was replaced every 5 days. Utilization of water plants from Tissue Culture is a novelty to see heavy metal uptake sharply and precisely because it is sterile and free of water pollution.  Analysis of heavy metal uptake in aquatic plants using NAA (Neutron Activation Analysis) Method.   The result is Ciliwung River waters contain Aluminum (Al), Brom (Br), Calcium (Ca), Cerium (Ce), Cobalt (Co), Chromium (Cr), Iron (Fe), Lanthanum (La), Manganese (Mn), Magnesium (Mg), Scandium (Sc), Sodium (Na), Strontium (Sr), Thorium (Th), and Zinc (Zn). Bacopa sp has shown the ability to absorb large amounts of heavy metal elements with a 100% survival rate, with the highest absorption element being Calcium (Ca) of 2.7191, 76 mg / kg.  Murdannia was unable to absorb La and Ce and was the weakest species among the species tested.
