Abstract

A number of activities occur around the Cikijing River in Rancaekek area, West Java, such as industrial and domestic activities. The various activities could decrease the quality of the river and surrounding environment due to anthropogenic pollutants that might be produced. Since the Cikijing River is also used as the source of irrigation, paddy fields around the river could be also be affected. The presence of pollutants in river sediments and agricultural soils over a long period could change their magnetic properties. Magnetic susceptibility of Cikijing River sediments and soils of the paddy fields in the surrounding have been examined considering that magnetic properties could represent environmental conditions. The results show that river sediments have magnetic susceptibility (cLF) in range of 356.2-456.3 (×10-8) m3kg-1, whereas soils samples have cLF varying from 94.1 to 347.1 (×10-8) m3kg-1, suggesting domination of ferrimagnetic minerals. The cFD (%) is <4% indicating the anthropogenic origin of magnetic minerals.  Electron microscopy images show the imperfect octahedral and spherules shapes of magnetic grains that supports magnetic susceptibility analysis about the source of magnetic minerals. Elemental composition analysis reveals Fe and O’s content as main elements, including minor elements of Ca, Mg, Al. Si, Ti and Cr

Abstract

Sarimukti landfill serves as a waste disposal site. Leachate generated from waste accumulation is discharged through pipelines into multiple retention ponds. This study aims to assess contamination levels in leachate deposits by analyzing the magnetic properties and morphology of magnetic minerals collected from four retention ponds, along with measurements of pH, EC, and TDS in the pond water. Magnetic susceptibility values range from 37.4 – 409.5 (×10⁻⁸) m³/kg, indicating ferrimagnetic mineral dominance. The  values range from 0.81% - 5.96%, where  >2% is often associated to pollutant-contaminated soils. A negative correlation between  and  suggests a minor contribution of superparamagnetic grains from pedogenesis. Scanning Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS) analysis identifies spherule and hedral magnetic mineral shapes, with O and Fe as dominant elements and minor Ti, indicating magnetite and titanomagnetite presence. Other elements, including C, Mg, Al, Si, K, Ca, and Mn, likely originate from anthropogenic sources.
