Abstract

Indonesia has a life-oriented river. As much as 68 percent of the quality of river water in Indonesia is heavily polluted, including the Ciliwung River in DKI Jakarta Indonesia. The pollution can affect river ecosystems, especially river biota such as plecostomus species found in the Ciliwung River. Plecostomus that have dominated Ciliwung River are widely used by traders to be used as processed raw material products. The purpose is to identify the content of heavy metals, especially lead (Pb), mercury (Hg) and cadmium (Cd) in the flesh of plecostomus from the Ciliwung River in Jakarta. The methods employed were collecting plecostomus samples, plecostomus flesh preparation, and metals content analysis with XRay Fluoresence (XRF) Spectrometer. The metal results identified with the XRF method on the flesh of plecostomus as much as 57 metals and there are three types of heavy metals of Pb, Hg and Cd. The concentration of heavy metals of Pb, Hg and Cd exceeds the maximum value of SNI threshold. Therefore, plecostomus flesh from Ciliwung River Jakarta is not feasible for consumption.
