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

Chemistry learning at the high school level often faces challenges in how to create interesting and fun learning for students. the current paradigm of chemistry subjects is often considered scary by students, so it is necessary to take an innovative approach with the main focus of this service is to create a positive and inspiring learning experience in the school environment, motivating students to be more actively involved in chemistry learning. The service aims to explore the implementation of fun chemistry practicum as a strategy to increase students' interest in learning at SMA Negeri 1 Pagimana. This practicum was designed with the aim of changing the conventional chemistry learning paradigm into a fun and memorable experience. Through interactive and visual experiments, students are invited to actively participate in practical activities involving simple chemical reactions and demonstrations that arouse their curiosity. The initial evaluation showed a positive change in students' behavior as seen from their enthusiasm in participating in this activity.
