<![CDATA[The Putri Cempo landfill serves as the final disposal site for organic and inorganic waste. Waste from the landfill can dissolve and settle in river sediments, potentially accumulating heavy metals like iron (Fe) and manganese (Mn), which bind easily to organic matter. This study aims to determine the content of Iron (Fe) and Manganese (Mn) in rivers around the Putri Cempo landfill. The concentration of Fe and Mn was analyzed using Atomic Absorption Spectrometry (AAS) referring to SNI 6989.84:2019, with sediment sampling conducted in rivers around the Putri Cempo landfill. Sediment sampling was conducted in these rivers, revealing Fe levels of 1519.414245 mg/L and Mn levels of 130.033 mg/L. Analysis indicates that Fe concentrations exceed the established quality threshold, while Mn levels remain below it. Heavy metals like Fe and Mn negatively impact abiotic and biotic environments, including human health and agricultural productivity. Elevated heavy metal levels disrupt ecosystem balance and pose health risks, making their management crucial. Reducing heavy metals in river sediments near the landfill is essential. Remediation efforts using bioremediation and phytoremediation technologies can help mitigate these impacts. Ongoing efforts are necessary to control heavy metal contamination in river sediments, ensuring ecosystem stability and public health.]]>
