Riset Geologi dan Pertambangan

Riset Geologi dan Pertambangan - Geology and Mining Research (RGP) is an open-access journal managed voluntarily by Earth science enthusiasts, supported, and published by BRIN Publishing (Penerbit BRIN). We believe that Earth science research should be inclusively accessible for everyone. There is no fee to submit manuscripts and no cost to read our published articles in RGP. This journal publishes research papers, reviews, and short communications in geosciences-related interdisciplinary areas related to geosciences.

We are pleased to invite researchers and practitioners in these fields to contribute to the journal by sharing their research, insights, and perspectives. This platform aims to foster discussions, address current trends and challenges, and explore state-of-the-art solutions to various issues within the scope of geosciences and related disciplines.

A Preface from the Editors
Dear RGP readers, We present the second issue of Volume 34 of Riset Geologi dan Pertambangan (Geology and Mining Research). This second issue publishes five papers dealing with engineering geology, geological resources, sedimentary geology, and hydrogeology. In the first article, Dzaki et al. present landslide susceptibility zone using the weight of evidence method in the south of Yogyakarta. Their landslide susceptibility map shows that the research location is predominantly characterized by areas with medium to high susceptibility to landslides. Furthermore, the medium and high susceptibility zones are situated close to the rivers that related to the alignment of faults. Kamal et al. discuss modelling a two-dimensional map of soil parameters in Bengkulu based on research points strategically distributed throughout the city. The parameters include shear wave velocity, cone resistance, and corrected standard penetration test. The research points represent the diverse soil conditions in the area, making the modelled soil parameters useful for planning construction. The third article by Solihin et al. briefly reviews different aspects of nickel ore, such as its history, types, distribution, demand, and the technology used for mining and processing it. Indonesia has significant nickel ore deposits, primarily in the form of laterite, due to its tropical climate with high temperatures and rainfall. The authors also discuss advanced materials made from laterite ore, including photocatalysts and batteries. In the fourth article, Anhaer et al. clarify sedimentary facies and sedimentation mechanism of volcaniclastics of Cikarang Member of Jampang Formation in southern part of Bogor Trough. They measured stratigraphy of the rock units supported by petrographic analysis and paleontological analysis. The rock units consist of 11 lithofacies deposited in inner-middle fan with changes in depositional sub-environment variations of channels, sandy lobes, silty-sandy distal lobes, and proximal levees. The volcaniclastics are deposited by turbulent current with various cohesive debris flows. The last paper by Nugraha et al. evaluates the performance of the Krylov Subspace method with adaptive preconditioning compared to classical iterative methods, such as Gauss-Seidel, Jacobi, and Successive Over-Relaxation (SOR), in the simulation of steady-state groundwater flow on a 2D grid. They conclude that the Krylov Subspace method with adaptive preconditioning is the best solution for applications that require high efficiency in groundwater flow computing. We sincerely acknowledge all the authors and reviewers for their valuable contributions to this issue. We recognize all the editorial members and staffs for their continuous fineness support for the publication of this volume. Happy new year and we wish all of you a successful continuation in scientific work and achieving interesting results of scientific research in the coming year, all the best! The Editors of RGP
