Abstract :
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.
