      Abstract
      Pembangkit Listrik Tenaga Uap (PLTU) merupakan salah satu pembangkit tenaga listrik yang menjadi bagian terpenting untuk kegiatan industri. PLTU juga menghasilkan limbah air buangan yang mengandung logam berat dan secara berkala dibuang langsung ke laut yang dapat berbahaya bagi makhluk hidup. Tujuan penelitian ini adalah mengetahui pola sebaran limbah Cu secara spasial dan temporal pada limbah cair PLTU dengan menggunakan metode pemodelan. Skenario model dilakukan menggunakan OpenFlows FLOOD selama 14 hari pada bulan Februari dan Agustus tahun 2020. Validasi hasil model pasang surut menggunakan metode Root Mean Square Error (RMSE) dengan nilai 0.282. Kecepatan arus di perairan sekitar Selat Sunda pada bulan Februari 2020 berkisar antara 0.016 – 19.892 cm/s dan pada bulan Agustus 2020 berkisar antara 0.018 – 11.125 cm/s. Rata-rata konsentrasi Cu pada bulan Februari 2020 sebesar 0.01884 mg/l dan pada bulan Agustus 2020 sebesar 0.01374 mg/l. Konsentrasi tertinggi Cu terdapat pada dekat sumber dan menurun saat menjauhi sumber. Hal ini disebabkan adveksi yang disebabkan oleh arus dalam penyebaran Cu.
       
      Steam Power Plant is one of the power plants which is the most important part for industrial activities. Steam Power Plant also produces waste water containing heavy metals and is periodically discharged directly into the sea which can be harmful to living things. The purpose of this study was to determine the distribution pattern of Cu waste spatially and temporally by using the modelling method. The model scenario was carried out using OpenFlows FLOOD for 14 days in the February and August 2020. Validation of the tidal model results using the Root Mean Square Error (RMSE) method with a value of 0.282. The current velocity in the waters around the Sunda Strait in the February 2020 ranges from 0.016 – 19.892 cm/s and in the August 2020, it ranges from 0.018 – 11.125 cm/s. The average concentration of Pb in the February 2020 is 0.01884 mg/l and in the August 2020 is 0.01374 mg/l. The highest concentration of Cu is near the source and decreases as it moves away from the source. This is due to the advection caused by the current in the dispersion of Cu.
