Abstract

Lampulo Marine Fishery Port in Banda Aceh serves as a major hub for fishing and trade activities, making it vulnerable to anthropogenic pollution, particularly heavy metal contamination. This study, conducted in December 2021, investigated lead (Pb) concentrations in sediment and water and evaluated the bioremediation potential of Staphylococcus aureus. Sampling sites were selected using a purposive method, and Pb concentrations were measured using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Initial analysis revealed high Pb concentrations: 210.62–247.93 mg/Kg in sediment and 161.91–168.23 mg/L in water, exceeding thresholds established by the Swedish Environmental Protection Agency (SEPA) and Indonesian environmental standards. Bioremediation was then applied using S. aureus, a gram-positive bacterium known for its biosorption capabilities. Post-treatment results showed a significant reduction in Pb concentrations to 0.72–2.72 mg/Kg in sediment and 0.18–1.55 mg/L in water. These findings confirm that S. aureus plays a vital role in reducing lead pollution and has strong potential as a bioremediator in marine environments affected by industrial and port-related activities.
