Kenjeran sea waters were polluted by several types of heavy metals such as copper (0.015mg/L), lead (0, 0036 mg/L), and mercury (0.001mg/L). Consuming Anadara granosa containing heavy metals exceeding the standard is very dangerous. The purpose of this study was to determine the effect of pineapple leaf and peel extract on reducing levels of copper, lead, and mercury in Anadara granosa in Kenjeran. Methods: Treatment without giving pineapple leaf and peel extract (Control) and treatment with pineapple leaf and peel extract using 0% and 3% concentrations. The results of heavy metal levels were in the form of numbers indicating the content of heavy metal levels in Anadara granosa determined in mg/kg using AAS. Results: The average copper concentration of 0% was 5.037mg/kg, and the 3% concentration was 2.563mg/kg, the average lead concentration at 0% concentration was 2.4333mg/kg and the concentration of 3% is 1.4433mg/kg, the average mercury concentration of 0% is 0.963mg/kg, and the concentration of 3% is 0.323mg/kg (4) Conclusion: there is an effect of pineapple peel and leaf extract on the decrease in copper levels by 50.88%, lead levels by 59%, and 33.54% decrease in mercury levels.
