Hubungan Bahan Organikdengan Kepadatan Bivalvia Di Sungai Pengambang, Desa Okura, Kecamatan Rumbai Pesisir, Pekanbaru

This study aimed to analyze the Correlation between sediment organic matter content and bivalve density in the Pengambang River, Rumbai Pesisir, Pekanbaru. The research was conducted from April to June 2025 at five purposively sampled stations. Observed parameters included water quality (temperature, pH, DO, BOD , current velocity), sediment fractions, organic matter content, and bivalve species and density. Data were analyzed descriptively and by simple linear regression. Three bivalve species were identified: Geloina coaxans (lokan), Corbicula fluminea (remis), and Unio pictorum (kijing). Mean bivalve densities per station were: Station 1 = 0.00 ± 0.00 ind/m², Station 2 = 5.67 ± 4.41 ind/m², Station 3 = 5.67 ± 4.41 ind/m², Station 4 = 8.56 ± 3.37 ind/m², and Station 5 = 6.33 ± 5.13 ind/m² (range 0.00–8.56 ind/m²). Sediment organic matter ranged from 9.28% to 19.23%, highest at Station 4. Regression analysis indicated a positive relationship between organic matter and bivalve density: y = -4.307 + 0.514x (R² = 0.526; r = 0.725). These results highlight the importance of organic matter for bivalve abundance, while other environmental factors such as DO, pH, current velocity, and substrate also influence their distribution.
