Abstract

Rare earth elements (REEs) are a group of seventeen metallic elements consisting of scandium (Sc), yttrium (Y), and fifteen other lanthanide elements. Rare earth metals have an important role in various technologies, so the analysis and separation of these elements from their minerals is very important to do. This study aims to characterize the tailings through X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) techniques. The results of XRD analysis show that the mineral composition of tailings is dominated by quartz (SiO₂) with a percentage of 88%, followed by albite (NaAlSi3O8) with a percentage of 11%.  In addition, the results of XRF analysis show that the main elemental composition in the tailings consists of SiO₂ (69.294%), Al₂O₃ (20.20%), and Fe₂O₃ (4.681%). In addition, heavy metal concentrations in the tailings indicate a potentially serious risk of environmental pollution, with arsenic (As) reaching 100 ppm and mercury (Hg) more than 5 ppm. In addition, rare earth elements identified in the tailings include cerium (Ce) at 14,578 ppm, lanthanum (La) at 7,850 ppm, and neodymium (Nd) at 6,897 ppm. This method is expected to help tailings management, reduce environmental impacts, and support sustainable mineral utilization.

Abstract

The contamination of animal-based foods poses risks to consumer health and economic stability, including trade losses and reduced consumer confidence. As the national reference laboratory under the Ministry of Agriculture, Indonesia, the Quality Testing and Certification Agency for Animal Products (BPMSPH) ensures product quality and certification. However, increasing sample volume and limited resources create service challenges, requiring urgent improvements to meet clean and responsive public service standards. This study aims to develop strategies for enhancing BPMSPH services toward Clean and Serving Bureaucracy Area (WBBM) standards. A mixed-method approach was used, combining primary data from interviews and questionnaires with secondary data from relevant agencies. SERVQUAL and AHP analyses identified service gaps and prioritized improvements. Findings show that BPMSPH services do not fully meet customer expectations, with key gaps in digital service accessibility, officer problem-solving capabilities, and customer assistance availability. AHP analysis prioritizes assurance and responsiveness, emphasizing the need for enhancing officer competency and developing digital services. The implementation of these strategies is expected to enhance BPMSPH’s service efficiency, increase customer satisfaction, and support the achievement of WBBM certification. By strengthening service assurance and responsiveness, BPMSPH can provide more professional, effective, and accessible public services, aligning with stakeholder expectations and regulatory standards
