Abstract

Soil elements, based on their abundance in the earth's crust and petrogenetic analysis aim to divide soil elements into several groups, namely major elements, trace elements and rare earth elements (REE). The research location is located in the Beruang Kanan area, Tumbang Miri District, Gunung Mas Regency, Central Kalimantan Province. The major elements and trace elements of the host rock were obtained from X-ray fluorescence (XRF) analysis and Plasma-Coupled Mass Spectrometry (ICP-MS) methods. Volcanic rocks from the Kanan Bear prospect The volcanic magmatic affinity in the study area is calc-alkaline this chemical characteristic is clearly reflected by the type of volcanic rock which is determined based on its chemical classification, which is generally igneous rock of the calc-alkaline magma series type so it is interpreted to originate from a convergent tectonic environment continental edge.

Abstract

Dental fluorosis is a disorder of mottled or mottled enamel structure as a result of excess fluoride intake during tooth formation. Water is one source of fluorine. The purpose of this community service is to assist the community in improving dental health and preventing dental and bone fluorosis. The implementation of this community service uses lecture and discussion methods. The stages of this service include pretest, delivery of material, post test, and discussion sessions. Post test results show an increase in community knowledge. It is hoped that this increase in knowledge can be applied by the Mojosari village community in an effort to procure water to meet their needs. Keywords: fluorosis, fluorosis, Mojosari village

Abstract

The mineralizing bearing rocks on the Right Bear prospect are andesite. Geochemical data of rocks indicate that they are classified as intermediate igneous rocks rich in silica. The composition of andesite silica is approximately 60% with a total alkali (Na+K) of about 3.6%. Based on this data, it is known that the dacite affinity is calc-alkaline. The volcanic rocks of the Right Bear prospect are primarily andesite. This study aims to determine the affinity of magma and geochemical characteristics of volcanic rocks in the Beruang Kanan area, Central Kalimantan, as the basis for the interpretation of tectonic settings and mineralization potential. Geochemical analysis was carried out using the X-Ray Fluorescence (XRF) method for the main oxide element and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for trace elements. Samples that have an LOI value of less than about 2% by weight are assumed to be unaltered or fresh rocks and these rocks are generally characterized by the presence of relative euhedral phenocrites and mineral grains and the absence of secondary hydrothermal minerals. The results of the comparison of Co and Th (Hastie, et al., 2007) on samples of fresh/slightly altered rocks and completely altered rocks are included in the affinity of magma of the alkaline limestone type. The results of the comparison of Zr/Y and Th/Yb (Ross & Bedard, 2009) show that samples of fresh rocks and altered rocks are included in the affinity of magma of the alkaline calcage series. Based on the results of the plotting of some of the above methods, it can be concluded that the magma affinity of the Beruang Kanan area belongs to the type of alkaline limestone which can be interpreted as being related to the within plate (in the plate) in the form of a continental expansion zone. This finding has important significance for the exploration of Cu-Au epithermal-porphyry mineralization in the Central Kalimantan region, given that rocks with calc-alkaline affinity in the within plate setting are often associated with economical mineralization systems.

Abstract

The Schwaner Mountains stretch in the middle. Identification of geological structures that play a role in the formation of metallic mineral deposits is necessary for more efficient mining exploration and exploitation. The Right Bear is a mining site located on a remote hill in the central part of the island of Kalimantan. This study aims to determine the condition of geological structure and the influence of geological structure on the distribution of copper mineralization at the research site. In this study, surface data was collected in the form of lithological description data and data on the structure of bridles and veins in rocks. The equipment used is a geological compass, a geological hammer, GPS, a magnifier, and others. In general, the stratigraphy of the research area is divided into 3 rock units that can be seen on the geological map, in order from old to young, namely the lithology of the Sandstone Unit, the Dacitic Tuf Unit, the Andesite Unit, and the Quartz Sand Deposit Unit. The mineralization of the Right Bear area consists mainly of high Cu sulfide mineralization. It is related to copper mineralization. Associated mineralization is generally controlled by bridle and fault structures. Mineralization is hosted by volcanic and volcaniclastic rocks in the research area, especially in the middle and southeast of the research area. The geometry of a vein with a width of > 1 cm is called a vein, if it is < 1 cm wide it is called a vein and if it is < 1 mm it is called a vein cord. These veins generally have the direction NNE SSW, NE-SW, NW-SE and WNW-ESE.

Abstract

Acid mine drainage generates environmental liabilities that mining operators must translate into measurable management costs. This study assesses the cost-based environmental liability of acid mine drainage management within the Integrated Geo-Hydrochemical Risk Assessment (IGHRA) framework by linking pollution risk, treatment performance, and environmental cost into a single risk-to-cost evaluation. The study uses source characterization, mine water quality data, compliance-based risk indicators, treatment performance, and operational cost components to estimate two principal cost categories, namely restoration cost and preventive expenditure cost. Restoration cost represents the annual cost required to restore contaminated mine water until all regulated parameters comply with the applicable standard. In contrast, preventive expenditure represents the five-year cost required to suppress future acid generation from potentially acid-forming material through selective handling, temporary stockpiling, installation of compacted clay cover, and runoff control. The results show that the only CaO scenario produces the lowest treatment cost, but does not achieve full compliance because sulfate remains above the standard. The CaO 10 g/L and BaCl₂ 3.0 g/L scenario achieves full compliance and provides the most economical restoration cost among the compliant options, with an estimated value of IDR 516,463,856 per year. The total preventive expenditure cost over five years reaches IDR 3,832,950,186. At a midpoint selling price of IDR 89,000 per ton, the compliant CaO and BaCl₂ scenario exerts an environmental cost pressure of 8.58 percent on projected gross revenue. These results show that the IGHRA framework can convert acid mine drainage risk into measurable environmental liability and can support technically grounded and economically accountable mine water management.

Abstract

The Ranang-Kasimbar geothermal system in Central Sulawesi is located within the West Sulawesi Mandala, an area significantly influenced by the active tectonic zone of the Palu-Koro Fault that controls the emergence of surface manifestations. This study aims to characterize the water chemistry of the Ranang-Kasimbar hot springs through surface geological mapping and fluid geochemical analysis, which includes cation-anion analysis, stable 18O and 2H (D) isotopes, and geothermometer calculations for subsurface temperature estimation. The geological conditions of the study area are composed of Cretaceous-Eocene metamorphic rocks, Tertiary intrusive rocks, and Quaternary sedimentary rocks, with structural controls in the form of north-south trending strike-slip faults and a normal fault system that forms a central depression zone as controls for the emergence of manifestations. Field data identified hot springs with surface temperatures ranging from 55–61°C and alkaline pH (~9). Geochemical analysis results classify the geothermal fluid as a chloride type indicating a deep reservoir origin, with a Cl/B ratio indicating strong interaction with igneous rocks and partial equilibrium conditions. Isotope analysis indicates a dominant mixing with meteoric water with very low oxygen-18 enrichment. Reservoir temperature estimation using a Na-K geothermometer and a silica-enthalpy mixing model indicates a minimum temperature of 130°C, thus categorizing it as a medium enthalpy system. This geothermal system is controlled by secondary permeability from normal and strike-slip fault structures, with the heat source suspected to originate from residual heat from Plio-Pleistocene andesitic intrusions.

Abstract

Soils in gold mining areas have the potential to contain heavy metals from rock weathering.  Such soil was planted with sweet sorghum to increase land productivity in Boto Village, Wonogiri Regency, Central Java during the dry season.  The harvested crop was not used for food, but processed into biofuels through fermentation and distillation.   Accordingly, the aim of this research was to trace the presence of several heavy metals in vinasse, a by-product of sweet sorghum stem juice fermentation process, from plants grown on soil in a community of gold mining area.  Two varieties of sweet sorghum, Samurai 1 and Samurai 2, were cultivated on this soil. Then, they were harvested and the sorghum stem extract was fermented to produce ethanol.  Distillation process was carried out on the fermented juice to increase the ethanol concentration, leaving behind vinasse.  Chemical analysis was carried out on the chemical properties of the soil (pH, CEC, Organic-C, total-N, available-K, and potential-P), and content of the heavy metals of Fe, Mn, Pb, and Cu in the soil, juice, and vinasse.  The soil exhibits a neutral reaction, low salinity, organic-C, total-N, available P and CEC.  The levels of Fe, Mn, Pb, and Cu in soil are 7.8%, 0.1%, 76.00 ppm, 23.81 ppm. In the juice, these concentrations were 9.66, 21.14, 1.49, 1.64 in ppm. In the vinasse, they were 5.29, 28.15, 1.05, 0.73 ppm, respectively.  These results indicate that heavy metals in soils could be absorbed by sorghum crops and they were absorbed in the stems of Samurai 1 and 2 sweet sorghum varieties, extracted into the juice, and partially remained in the vinasse.
