Abstract: The Citarik River is one of the Citarum sub-watersheds that originates in the Kareumbi Masigit Forest Conservation Area, Sumedang Regency. The number of human activities around the upstream Citarik River can affect the quality of water and sediment. To identify the anthropogenic effect, we conducted measurements of common parameters used to determine water and sediment quality, namely EC (Electrical Conductivity), TDS (Total Dissolved Solids), and pH. Thus, to analyze the characteristics of sediment, we used magnetic susceptibility measurements, heavy metal content tests, Scanning Electron Microscopy, and Energy Dispersive X-Ray Spectroscopy (SEM-EDS) tests. The results showed that the hydrological parameter values of sediment were still at a predetermined threshold except for pH at several locations. The results of low-frequency magnetic susceptibility (𝜒𝐿𝐹) around (1308.696–3071.020) × 10-8m3/kg while the frequency-dependent magnetic susceptibility (𝜒𝐹𝐷%) values around (0.955–2.405) %. Those values have a negative correlation which indicates that the sediment sample has been affected by anthropogenic materials. This is supported by heavy metal test results where almost all elements pass the specified threshold. Furthermore, there is a positive correlation between magnetic susceptibility and heavy metals originating from human activities and the results of the SEM-EDS test indicate the presence of a mineral with a spherule shape where the mineral with that shape is a mineral from anthropogenic activity.
