ABSTRACT 

Indonesia possesses abundant natural resources, including underutilized beach sand deposits. This study analyzes the mineral composition of sand from Jumiang Beach, Pamekasan Regency, using X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD) analyses following an extraction process. The XRF results show that the western area exhibits the highest silica (SiO₂) content, reaching 87.10 wt% at a depth of 1.5 m, while the central area contains 85.40 wt% at 1.5 m, and the eastern area contains 81.32 wt% at a depth of 0.5 m. Qualitative XRD analysis confirms that silica in the quartz phase is the dominant crystalline component in all samples, accounting for more than 90% of the detected crystalline phases, followed by CaCO₃ (<4%). The highest diffraction peaks were observed at 2θ values of 20.78° and 26.47°, which are characteristic of quartz. These results indicate that Jumiang Beach sand is predominantly composed of quartz-phase silica, demonstrating strong potential as a raw material for advanced industrial applications.
