Abstract

This research is located in the IUP area of PT Wijaya Karya Bitumen, C Block Kabungka Mine, Winning Village, Pasarwajo District, Buton Regency, Southeast Sulawesi Province. This study aims to classify asbuton trap rocks based on their chemical composition with XRF (X-ray fluorescence) and XRD (X-Ray Diffraction) analysis. The results of the XRF analysis showed that the asbuton trap rocks in the research area were dominated by CaO, MgO and SiO2 compounds. The CaO content varies between 24.56% to 44.46%. The SiO2 content in the samples varies, ranging from 7.81% to 12.54%. Three samples, namely TR1C-001, TR1C-002, TR1C-003 each contain MgO 0.57%, 0.85%, and 0.96%, while the other two samples, namely TR2C-001, TR2C-002 each contain MgO 14.40% and 17.51%, respectively. The results of XRD analysis showed three dominant minerals, namely Calcite (CaCO3), Quartz (SiO2) and Dolomite (CaMg(CO3)2). Based on the results of geochemical analysis (XRF and XRD) showed that the asbuton trap rock in the study area consists of 2 (two) types of carbonate rocks, namely Argillaceous Limestone with a CaCO3 content of 76.6% to 79.7% and slightly calcitic dolomite.

Abstract

In lateritic nickel mining, peridotite rock serves not only as the primary source of nickel laterite but also plays a crucial role in slope design and the development of mining infrastructure, such as the construction of mine roads. Additionally, economically non-viable peridotite can be repurposed as fill material or construction raw material if it meets specific technical criteria. This study aims to analyze the ripperability and abrasiveness of peridotite rock in the research area to determine the most effective excavation method. The analysis was conducted using joint spacing data and rock strength obtained through measurements of rock mass discontinuities using the scanline survey, uniaxial compressive strength (UCS) tests, and point load tests. The findings indicate that the rock in the study area can be classified into three main categories based on joint spacing and strength: easy ripping, hard ripping, and very hard ripping. Based on the analysis, the recommended heavy equipment includes Bulldozer models D7G and D8K, which are suitable for the rock rippability categories identified at the site. Rocks with high strength values exhibit high abrasiveness, leading to accelerated wear on heavy machinery. Therefore, selecting wear-resistant equipment and implementing more intensive maintenance planning are essential to improving operational efficiency in the study area.

Abstract

Facies analysis and thin-section petrography are complementary and essential approaches for determining the lithological characteristics of deep-water deposits. Deep-water sediments are formed by diverse depositional processes such as turbidity currents, debris flows, slumps, and pelagic suspension settling, producing a wide range of lithofacies with distinctive textural, compositional, and sedimentary structural attributes. This literature review synthesizes studies that apply facies analysis and thin-section petrography to characterize deep-water deposits across various basins and geological ages worldwide. Field-based facies analysis emphasizes lithology, sedimentary structures, bed geometry, and vertical–lateral facies relationships to reconstruct depositional environments. In contrast, thin-section petrography provides microscopic insights into mineral composition, grain texture, cement types, porosity, and diagenetic features that are not observable in the field. The integration of these methods, often combined with advanced techniques such as XRD, SEM, and geochemical analyses, has proven effective in distinguishing lithofacies, understanding sedimentary processes, and evaluating reservoir quality. The review highlights that grain size, sorting, cement type, pore-throat size, and diagenetic processes are key controls on lithological characteristics and reservoir potential in deep-water systems. Therefore, the combined application of facies analysis and thin-section petrography provides a comprehensive framework for interpreting deep-water sedimentary systems.

Abstract

Travertine is a non-marine carbonate rock precipitated from calcium- and bicarbonate-rich waters, commonly associated with hot springs, streams, and lakes in tectonically active regions. This study presents a systematic literature review of travertine deposit characteristics, encompassing mineralogical composition, geochemical signatures, petrographic textures, morphological types, isotopic properties, biotic–abiotic controls on formation, early diagenesis, and petrophysical implications. The synthesis indicates that travertine is predominantly composed of calcite, with aragonite forming under conditions of elevated temperature, high Mg/Ca ratios, and rapid CO₂ degassing. Travertines display exceptional textural diversity, ranging from abiotic crystalline crusts to microbially mediated fabrics such as shrub, peloidal, and stromatolitic structures. Major morphologies include fissure ridges, mounds, terraces, cascades, and slopes, strongly governed by tectonic setting, topography, hydrology, and substrate geology. Stable isotopes (δ¹³C and δ¹⁸O), strontium isotopes, trace elements, and REE patterns effectively constrain fluid provenance and distinguish thermogene from meteogene travertines. Microbial activity plays a crucial role in biomineralization, influencing precipitation rates, crystal morphology, and lamination patterns. Early diagenetic processes occurring during active deposition may significantly modify primary fabrics and geochemical signals. Travertine petrophysical properties exhibit distinctive porosity–velocity relationships, making them valuable analogues for subsurface carbonate reservoirs. This review highlights that travertines record complex interactions among physical, chemical, biological, and geological processes and hold significant value for paleoenvironmental reconstruction and carbonate reservoir studies.

Abstract

The Sampolakosa Formation in Buton Island, Southeast Sulawesi, Indonesia, is predominantly composed of packstone calcarenite, which is brownish white when fresh and brown when weathered, and contains 57.8% skeletal grains, 34.3% micrite, 6.1% sparry calcite, and 1.8% pores/voids. Petrographic analysis indicates a grain-supported fabric, reflecting deposition in a moderate-energy environment capable of accumulating bioclasts while retaining a micrite matrix. Planktonic foraminiferal assemblages, including Globorotalia plesiotumida, Globorotalia acostaensis, and Globorotalia mayeri, constrain the age of the formation to the Late Miocene (~11–6 Ma), consistent with its stratigraphic position overlying the Tondo Formation and underlying the Wapulaka Formation. Benthic foraminifera, such as Cibicides lobatulus, Lagena sp., Bolivina sp., and Chrysalidina gradata, indicate deposition on a shallow to middle shelf (5–100 m) within a warm, clear tropical carbonate shelf characterized by moderate bottom-water energy, active currents, and generally well-oxygenated conditions with locally reduced oxygen levels. The combination of grain-supported packstone and micrite retention suggests deposition below the fair-weather wave base but influenced by occasional high-energy events, representing a transition from nearshore to middle shelf under relatively stable seabed conditions. These findings provide a robust framework for the biostratigraphy and paleoenvironmental reconstruction of the Sampolakosa Formation, contributing to regional stratigraphic correlations and insights into carbonate depositional systems.

Abstract

Baruga is a traditional building that serves as a venue for community meetings, social activities, and a symbol of cultural identity. However, the Baruga located in the cultural heritage area of Kampung Lama, Kombeli Village, has experienced physical deterioration due to the weathering of wooden materials and has limited capacity to accommodate community activities. This community service program aimed to develop a renovation design that improves the building's quality and capacity while preserving its traditional architectural character. The program employed a participatory approach consisting of coordination, field surveys, building measurements and documentation, Focus Group Discussions (FGDs), design concept development, design validation, and preparation of the final design document. The results indicate that the proposed renovation design replaces the main wooden structural elements with reinforced concrete to enhance structural strength and durability, while retaining wooden flooring as a representation of the traditional identity of the Baruga. In addition, the building dimensions were expanded to increase its capacity for social, cultural, and community meeting activities. The resulting design serves not only as a technical guideline for renovation but also as an instrument for preserving the architectural form, function, and cultural values of the Baruga as an important cultural heritage asset of Kampung Lama, Kombeli Village.

Abstract

Indonesia is highly vulnerable to tsunami disasters due to its location at the convergence of three major active tectonic plates. One of the most effective strategies for disaster risk reduction is improving public awareness and preparedness from an early age through school-based education. This community service program aimed to enhance tsunami disaster awareness and preparedness among students of SMKN 10 Konawe Selatan. The program was conducted through three stages: preparation, implementation, and evaluation. Educational activities were delivered through lectures, video presentations, interactive discussions, and tsunami disaster response simulations. The effectiveness of the program was evaluated using pre-test and post-test instruments to measure students’ knowledge improvement. The results showed a significant increase in students’ understanding of tsunami concepts, causes, early warning signs, self-rescue procedures, and evacuation measures. The disaster response simulation provided students with practical experience in implementing proper evacuation procedures. In addition, students demonstrated high enthusiasm and active participation throughout the program. The findings indicate that disaster education combined with simulation-based learning is an effective approach to improving tsunami awareness and preparedness among students. Continuous implementation of similar programs is recommended to strengthen disaster preparedness culture and reduce future disaster risks and impacts.

Abstract

Karstification is the dominant geological process controlling groundwater circulation and permeability in carbonate aquifers. Through the dissolution of carbonate rocks, karst processes create highly heterogeneous systems characterized by fractures, conduits, and interconnected channel networks that significantly influence groundwater flow dynamics. This literature review aims to synthesize current knowledge regarding the effects of karst on water circulation and permeability in carbonate aquifers based on hydrogeological, hydrochemical, geophysical, and numerical modeling studies from various regions worldwide. The review shows that karstification substantially enhances hydraulic conductivity and produces complex flow regimes ranging from diffuse fracture flow to turbulent conduit flow. The epikarst zone plays an important role in regulating infiltration and recharge distribution, while tectonic structures such as faults and fractures strongly control groundwater pathways and aquifer compartmentalization. Karst aquifers also exhibit strong spatial variability in permeability, making groundwater flow and contaminant transport difficult to predict using conventional hydrogeological approaches. In addition, the integration of equivalent porous medium (EPM), discrete fracture network (DFN), and conduit network (CN) models is essential for accurately representing karst aquifer behavior. Understanding the influence of karstification on groundwater circulation is therefore crucial for sustainable groundwater management and aquifer vulnerability assessment, particularly in regions facing increasing water demand and climate change pressures.
