This study aimed to assess the condition of the Dasun estuary, Indonesia, from the influence of heavy metals Cr, Cd, and Pb that accumulated in sediments and beach morning glory vegetation (Ipomoea pes-caprae). The results showed that the metal concentrations of Cr, Cd, and Pb in the sediments were 3.39–5.29 mg/kg, 0.21–0.29 mg/kg, and 5.36–6.87 mg/kg, respectively. The concentrations of metals that accumulated in the tissue of entire plants were 0.98–1.22 mg/kg (Cr), 0.31–0.40 mg/kg (Cd), and 0.94–1.23 mg/kg (Pb). Dasun estuary is still in the safe category for the living habitat, even though the concentration of Cd was relatively high and was estimated to originate from batik industry waste. The vegetation of Ipomoea pes-caprae was found to have a high ability to absorb Cd; thus, it can be used as a bioindicator for heavy metals in the environment.
