Abstract

The need for building materials is increasingly felt and expanded in line with the development of cities and regions, on the other hand mining activities can affect and damage the environment, such as what happened in the Barru, Sabangnaeri and Bottolai Rivers, where the former mines were left without reclamation. Based on this, a team from the Department of Geological Engineering, Hasanuddin University Makassar conducted counseling on batugunung mining to stone mining entrepreneurs in the Kamara - Bottolai area, Barru district in the form of Tri Dharma Perguruan Tinggi. This activity is expected to contribute, especially to stone mining entrepreneurs, to increase income and environmental safety. From the results of the field survey, several alternative materials of higher quality than currently managed (ultramafic rocks) were obtained for the community, namely dacite, andesite - trachea, diorite and limestone, scattered in several places in Barru Regency. The objectives of this community service activity are to: a. provide knowledge of rock quality and alternative locations; b. Provide technical guidance and mining work safety; c. Provide an understanding of environmental issues and the impact of mining

Abstract

The development of a geopark in the region should be initiated by the determination of geoheritage collected from the geological diversity inventory. The geoheritage initiation and preparation should be involved the educational institutions, we have assisted stakeholders of Bone Regency through the university community services (PkM) program in the form of the socialization of geoheritage in order to prepare and proposed Bone Geopark of South Sulawesi. To get an initial baseline of the geoheritage potential of Bone Regency and to measure participants' abilities, it begins with an FGD and a pre-test assessment, the results of the first FGD and pre-test activities showed that in general stakeholders have limited knowledge of the preparing document, characterization, and inventory of geoheritage, and geoheritage assessment. We have mentored geoheritage characterization, geodiversity inventory, and geoheritage assessment as problem-solving, which were conducted through surveys, desk study, and geoheritage assessment value methods. At the end of the activity returned to conduct FGD and post-test with involved all of the stakeholders. The results of the socialization program show a significant increase in the understanding of participants, especially the PERWIRA La Patau's was an increase of 28.5% (from 31.5% to 70%). Whereas representatives of the government, education institutions, and other non-government organizations still have limited understanding, increasing by 19.5% (from 17.0% to 36.5%). We still further proposed socialization and mentoring to prepare and propose geoheritage in the future. The geodiversity and landscape characteristics of the Bone regency can be divided into three morphology domains, namely: 1) The western part is demonstrated by the morphology domain of the highland of the volcanic complex that consists of non-volcanic, caldera, tower karst landscape features, 2) The central part is demonstrated by morphology domain of the Walanae valley that consisting of Walanae Depression and Walanae fault escarpment landscape features, 3) The eastern part is demonstrated by morphology domain of the Walanae structural lineament, the Kalamiseng volcano, the Taccipi cone karst and coastal line of the Bone Gulf landscape features. The results of the geodiversity inventory and geoheritage assessment of Bone Regency generally have suggested high scientific and educational values, moderate tourism potential, and low degradation potential. We concluded that this area has geodiversity potential and deserves to be submitted its geoheritage to the government.

Abstract

On September 28, 2018, a 7.5 Richter magnitude earthquake struck the Palu City neighborhood of Petobo. The tectonic activity along the Palu-Koro fault generated this earthquake, which resulted in soil liquefaction. The purpose of this study is to use microtremor measurements at 33 distinct places to investigate the properties of the soil layer after liquefaction. The obtained data was then evaluated utilizing Horizontal to Vertical Spectral Ratio (HVSR) methodologies such as Ground Shear Strength (GSS), amplification factor, and vulnerability index to determine the soil layer's properties and susceptibility. The dominant frequency ranges from 0.19 to 4.75 Hz, while the dominant period ranges from 0.21 to 5.17 seconds, according to the measurement results. According to these measurements, the silt layer varies between 5 and 30 m. GSS values in the 10-4 to 10-2 range indicate that soil cracking, subsidence, liquefaction, landslides, and compaction are likely. The soil vulnerability and amplification index values range from 2.36 to 4.37, respectively. These values show the potential level of danger, which might be low, medium, high, or extremely high. Peak ground acceleration varied from 299.52 to 301.52 gals, suggesting high to extremely high danger levels. The microzonation map created for this study is considered to be a useful resource for training disaster mitigation approaches and facilitating infrastructure development planning in the region.

Abstract

The problem of clean water with high iron content significantly impacts the quality of life of people in Indonesia, including in Mangasa Village, Tamalate District, Makassar. Residents face reddish wells, tap water, and a metallic odor caused by geological factors or old and rusty pipes, which pollute water sources and endanger health. As a solution, Community Service activities by the Geological Engineering Department of Hasanuddin University socialize the use of limestone to reduce iron levels in water. This socialization results from a collaboration between the Community Service team and the capstone design team of geological engineering students at Hasanuddin University in designing clean water filters. The activity began with delivering educational materials regarding water quality problems and the benefits of limestone, accompanied by easy-to-understand visualizations. After a pre-test was conducted to measure initial understanding, the community service team presented and simulated limestone utilization, followed by an interactive question and answer session. Then, a post-test was conducted to evaluate the increase in participants' understanding, which was analyzed to measure the effectiveness of the socialization. The evaluation results showed a significant increase in participants' knowledge of clean water quality, the impact of iron content, and the use of limestone as a filter, which was 72%. This increase reflects the high enthusiasm and motivation of the community in adopting clean water treatment methods.

Abstract

The Wapulaka Formation in Central Buton, Indonesia, is a tectonically complex carbonate system characterized by heterogeneous lithologies, including limestones, dolostones, and marls. This study integrates Electrical Resistivity Tomography (ERT) and X-Ray Fluorescence (XRF) to map the subsurface distribution and geochemical characteristics of limestone in the formation. Electrical Resistivity Tomography (ERT) surveys were conducted along four profiles, covering a total length of 495 meters, with an electrode spacing of 5 meters to identify resistivity variations linked to lithological changes, fractures, and karst formations. The collected data were processed and inverted with Res2DInv software, applying topographic corrections to produce high-resolution 2D resistivity models. The limestone samples were examined with an Epsilon 4 XRF spectrometer to ascertain the elemental concentrations, particularly the CaO and MgO levels. Borehole data were used to validate ERT findings and provide a lithological perspective. The amalgamation of the ERT and XRF datasets demonstrate a robust correlation between resistivity and chemical composition. High-resistivity zones (>5000 ?m) are associated with significant, high-purity limestone characterized by elevated CaO and reduced MgO levels, while low-resistivity regions (<1000 ?m) signify eroded, porous, or clay-rich portions with increased MgO and diminished CaO content. The Mg/Ca ratio, obtained from XRF analysis, acts as an indicator of dolomitization, with higher ratios linked to decreased resistivity values. This technology facilitated the creation of a predictive model for limestone quality utilizing resistivity, enhancing resource assessments and selective mining efficacy. This study illustrates the efficacy of integrating geophysical and geochemical methods to delineate intricate carbonate systems, providing insights into subsurface heterogeneity, diagenetic processes, and resource availability.

Abstract

This study investigated the lateral distribution of geochemical parameters in peatlands within the Punggur Besar River–Kapuas River Peat Hydrology Unit (KHG) in Kubu Raya District, West Kalimantan Province, Indonesia. Peatland degradation in this area is primarily caused by land clearing, uncontrolled drainage, and forest fires, which adversely impact the soil's physical and chemical properties. Key geochemical parameters analyzed include nitrogen (N), phosphorus (P), potassium (K), pH, organic carbon, and cation exchange capacity (CEC). Spatial distribution was mapped using GIS technology. The results showed significant variation in nutrient content and soil pH across the study area. Nitrogen content varied between 0.1% and 1.6%, indicating areas of high and low vegetation productivity. Low phosphorus levels in most regions suggest nutrient deficiencies, while potassium concentrations exhibit variability, indicating a potential need for fertilization. Predominantly acidic soil pH (2.8-6.3) challenges vegetation growth and increases fire risk. These discoveries contribute to a fundamental understanding of the geochemical dynamics of peatlands, indispensable for leading sustainable management and restoration efforts. By recognizing areas of high fertility and those requiring restoration interventions, this research assists effective land-use planning and climate mitigation strategies in degraded peatland ecosystems.

Abstract

Geologically, the Lake Matano area is an area of laterite deposits, where in these deposits there are heavy metal geochemical elements that can have a negative impact on the environment. This research was conducted in three rivers that surround the area and empties into Lake Matano, with the aim of analyzing the geochemical behavior of heavy metals in soil. The method used includes a literature study and observing the results of previous studies and testing the content of heavy metals with the AAS tool. The results showed the behavior of heavy metals in the soil around Lake Matano in the three rivers where metals that exceeded the critical number were Fe, Mn, Cu, Co, Ni. and which is still below the critical number limit is Cr metal. The presence of heavy metals in the soil at the research site is caused by the results of the disposal of waste from mining activities and anthropogenic activities where the end of the disposal goes directly to the ground so that the heavy metals contained in the disposal will enter the soil and experience contamination in nature so that the existing organic compounds have undergone degradation.
