    Sediment is a mixture from organic and anorganic materials that has big particle size. The type and quantity of elements found in the sediment are potential to contaminate the environment. The sediment of four ponds at Muara Fajar is possible to contain some types of dangerous metals as a result of waste degradation process. Hence, this study was carried out to analyze the concentration of some metals such as Cu, Fe, and C from the sediments. The concentrations of Cu and Fe were measured by using Atomic Absorption Spectrophotometer, while the content of organic carbon was determined by UV-VIS Spectrophotometer. Our results showed that the concentration of Cu was ranged between 0,4157 to 1,2646 mg/g. the highest content of Cu was found from third pond. Fe content was ranged between 0,4157 to 0,5893 mg/g, and the second pond had the highest content of Fe. The concentration of organic carbon was ranged between 0,0008 to 0,5586%, and its highest number was found from third pond.
