Kebumen is a region that is very interesting geologically due to the diversity of rocks with varying ages of formations and environments. Kebakalan Village, which is one of the areas in Karanggayam- Kebumen, has the Luk Ulo River connected to the Karanggayam- Sadang sediments. This river is a location that has alluvial gold deposits. Research on the composition of alluvial gold can be done using various analytical techniques, one of which is X-ray Fluorescence (XRF) analysis. The purpose of this study was to perform XRF analysis on samples collected from alluvial deposits in Kebakalan to determine the elemental composition of gold oxide compounds. The method used was laboratory testing at the Integrated Testing and Research Laboratory of Gadjah Mada University using an ED- XRF instrument made by Rigaku with the NEX-QC + QuantEZ model. The test results produced low-Z, medium-Z, and high-Z spectrum graphs, resulting in quantitative results where the highest percentage was found in quartz at 39.20%. This indicates that there is a gold content (Au) in the sample.
