Effects of land use on the number of coliform bacteria in boyong river, sleman

Abstract

Watershed management is important, especially to water management. River water pollution in the upstream has an impact on the water quality in the midstream and downstream. Boyong River is an upstream part of Code Watershed which has three dominant land uses. Land use activities in the Boyong River cause faecal pollution from animals or humans waste in river bodies. This can cause the presence of coliform bacteria in rivers, both Total Coliform (TC) and Fecal Coliform (FC). This study aims to determine the effect of land use on the number of TC and FC in the Boyong River. The study focused on three dominant land uses, mixed-use gardens, irrigated fields, and settlements. Sampling was carried out during the dry season and rainy season, using a purposive sampling method. Based on laboratory tests with the Most Probable Number (MPN) method, the number of TC ranged from <1,8 – 350.000 MPN/100mL and the number of FC ranged from <1,8 – 79.000 MPN/100mL. Third land use contributes to river pollution. Settlements have the highest number of TC and FC changing. During the rainy season, the number of TC and FC tends to be higher than during the dry season. Almost all sample points exceed the Boyong River allotment quality standard.

Determine the Impact of Bacterial Contents on the Quality of Tap Water in Hawija District Desalination Station.

“…The intestines of humans and animals are the final host for the presence of coliform bacteria therefore water and soil can be polluted with their feces [24]. The presence of E. coli in water sources gives evidence for the presence of other types of intestinal pathogens in the water, such as Salmonella and Shigella.…”

Detection of Heterotrophic and Coliform Bacteria in Two Rivers in Sidoarjo Regency, Indonesia: Buntung and Sinir Rivers

“…Hasil ini mengindikasikan perairan kedua sungai tersebut terkontaminasi lingkungan. Material kontaminan berasal dari aktivitas penggunaan lahan yang dapat mencemari badan air dan sebagian kontaminan mengandung fecal, sehingga dapat meningkatkan bakteri coliform di badan air (Puspitasari & Hadi, 2022). Divya & Solomon (2016) menambahkan bahwa total coliform merupakan kelompok bakteri yang umum ditemukan di lingkungan.…”
