This edition of Eksplorium features four (4) research articles from various scientific fields. The first paper, titled “Morphological Characteristics of Scoria Cones on the Eastern Part of Slamet Volcano, Karangreja, Purbalingga, Indonesia,” explores the morphological characteristics and volcanic landforms of scoria cones in the eastern part of Slamet Volcano, providing insights into their formation and geological significance. The second paper, “Preliminary Investigation of Catechin as a Natural Complexing Agent for Selective Recovery of Tantalum and Niobium from Hydrometallurgical Leachate of Bangka Tin Slag 2,” examines examines the potential use of catechin as a natural complexing agent for the selective recovery of tantalum and niobium from hydrometallurgical leachate, “Adsorption of Thorium(IV) from Aqueous Solution Using Natural Bentonite from Pacitan, Indonesia,” discusses the adsorption performance of natural bentonite from Pacitan for removing thorium(IV) from aqueous solutions. The final paper, “Study on TiO2 Extraction from Ilmenite Sand in Ketapang Regency Through Various NaOH Molar Ratios,” presents an investigation into the extraction of TiO2 from ilmenite sand using different NaOH molar ratios to optimize the extraction process.
