| Judul Artikel | Pollution Level of Trenggulun River Banyumas Based on Microbenthic Community Structure |
| Abstrak (Bhs. Indonesia) | Water quality is a measure of water conditions based on physical, chemical, and biological parameters that determine whether the water is safe and suitable for use. The water quality of the Trenggulun River in Banyumas can be assessed through analysis of the structure of the microbenthic community. Due to their sedentary nature and widespread distribution throughout the river, the structure of the microbenthic community in the Trenggulun River can provide important information for water quality management and ecosystem conservation, especially since this river originates from the Bleber spring and holds significant value for the community. The objective of this study is to determine the structure of the microbenthic community in the Trenggulun River, including composition, density, diversity, and dominance, as well as to assess the pollution level of the Trenggulun River in Banyumas based on the structure of the microbenthic community.This study was conducted from February to May 2025 at four stations representing upstream to downstream sections. This study used a purposive sampling survey method in the waters of the Trenggulun River in Banyumas. Samples were collected at four different points, including Station 1 (Cipete), Station 2 (Penusupan), Station 3 (Sawangan Wetan), and Station 4 (Notog). Sampling was conducted twice with a one-month interval. The variables observed were the structure of the microbenthic community, including density, diversity, and microbenthic dominance and the level of pollution and saprobic phase based on microbenthic. The parameters measured were the number of species and individuals to determine diversity, abundance, and dominance, and the number of species of several saprobity-determining microbenthic groups to determine pollution levels or water saprobity. Microbenthic density was calculated using the Sedgwick Rafter Cell (SRC). Microbenthic diversity was determined using the Shannon-Wiener Diversity Index (H’). The dominant microbenthic species are determined using the Dominance Index (D). The water quality of the Trenggulun River can be determined based on the diversity index using criteria based on the saprobic coefficient to identify the dominant organism groups and determine the level of pollution.This study identified 11 species of microbenthic in the Trenggulun River, with the highest composition level from the Bacillariophyta class. The highest density was found in the middle section, while diversity (H′ = 1,7–1,9) was classified as moderate and dominance (D = 0,19–0,21) was low. Based on the saprobic coefficient, most locations were classified as β-mesosaprobic (light pollution) and one location as β/α-mesosaprobic, indicating the presence of organic matter input but water quality was still relatively healthy. Based on saprobic coefficient analysis upstream, central, and downstream were categorized as βmesosaprobic (light pollution), while upstream-downstream transition was β/αmesosaprobic (moderate pollution). The findings indicate organic input from domestic and agricultural runoff, but overall water quality remains relatively healthy.
