Status Ekologi Perairan Sungai Umban Sari Kota Pekanbaru Dengan Bioindikator Makrozoobentos Menggunakan Metode Kurva ABC

---

This research was carried out in March-May 2024. This study aims to determine the abundance, community structure, biomass and ecological status of the waters of the Umban Sari River based on the macrozoobenthos ABC (Abundance and Biomass Comparison) Curve method. This research uses a survey method by determining sampling stations using purposive sampling consisting of three stations. Macrozoobenthos sampling was carried out 3 times with an interval of once a month (30 Day interval). The results showed that the found 8 macrozoobenthic species consisting of P. ampullacea, P. canaliculate, L. rubiginosa, B. sumatrensis, G. convexiusculus, I. exestus, M. pantherine and Schistosoma sp. The highest abundance of macrozoobenthos was found at station I upstream of the river with an average of 3,685 ind/m2 and the lowest was found at station III downstream of the river with an average of 2,148 ind/m2. The diversity and uniformity of the macrozoobenthos is in the medium category, there are no species that dominate. The highest macrozoobenthic biomass was found at station I upstream of the river with an average of 2,643 gr/m2 and the lowest was found at station III downstream with an average of 2,199 gr/m2. The K-Dominant Hypothesis of the ABC curve in the Umban Sari River is included in the category and condition of an undisturbed and unpolluted ecosystem. However, the dominance of the relative biomass (BR) line was found to be only slightly above the relative abundance (KR) line and was close to overlapping, this indicates that the ecosystem condition is starting to become polluted.
