We had analyzed the content of waste in sand on around the diamond mining in Cempaka Banjarbaru South Kalimantan. The method that was used with atomic absorption spectroscopy (AAS). AAS is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation by free atoms in the gaseous state. The result showed that metal in the sand as material research is silica (Si) of (41.4345 ± 0.5581)% and Iron (Fe) of (2.7769 ± 0.0371)%. This results information of Cempaka’s sand analysis are expected to be used as basis for optimal utilization of sand. Keywords: cempaka sand, atomic absorption spectroscopy (AAS)
