Analisis Konsentrasi Logam Berat Pb Dan Cu Pada Avicennia Alba Di Pesisir Pantai Dumai Barat Provinsi Riau

---

Coastal ecosystems play a crucial role in supporting biodiversity but are increasingly threatened by heavy metal pollution originating from industrial and domestic activities. The mangrove species A. alba possesses the ability to absorb heavy metals through phytoremediation processes, making it a promising bioindicator of environmental contamination. This study aimed to analyze the concentrations and variations in the accumulation of lead (Pb) and copper (Cu) in the roots, stems, and leaves of A. alba along the western coast of Dumai City, Riau Province. Fieldwork was conducted from January to February 2025 at two sampling sites: Pangkalan Sesai Village (Station 1) and Purnama Village (Station 2). Heavy metal concentrations were determined using Atomic Absorption Spectrophotometry (AAS) following wet digestion. Additionally, environmental parameters including temperature, salinity, and pH were measured. Data analysis involved descriptive statistics, non-parametric tests, and independent t-tests. The results indicated that both Pb and Cu were present in all plant parts. The highest concentration of Pb was found in the stems (7.05 µg/g), while Cu was most concentrated in the roots (5.38 µg/g), No statistically significant differences were observed among plant parts (p>0.05); however, a significant spatial difference in Pb concentrations between the two stations was detected (p
