Abstract

DOI:10.17014/ijog.6.2.153-174Exhumation and tectonomagmatic processes of the granitoid from Sulawesi were discussed using petrochemistry (e.g. petrographic and major element compositions) and geothermobarometry data (mineral chemistry data). Detailed petrographic observations were conducted to determine the mineral composition, texture, and structure of the granitoid rocks, whereas the whole rock composition were determined using XRF method, and the mineral chemistry was analyzed using Electron Microprobe Analyzer (EPMA). The granitoids are classified as calc-alkaline, metaluminous I-type. Pressures of 0.91 to 1.2 kbar and emplacement depths of 3.2 to 4.3 km at temperatures of 677 - 729°C were estimated for Mamasa Pluton. Whereas Masamba Pluton was emplaced at pressures of 2.3 to 2.8 kbar, temperatures of 756 - 774°C, and emplacement depths of 8.2 to 10 km. Moreover, Lalos-Toli and Sony Plutons were emplaced at temperatures of 731 to 736°C and 601 to 609°C, respectively. The pressures varying from 3.1 to 3.3 kbar and 3.2 to 3.4 kbar, equate to an emplacement depth of 11.3 and 11.6 km, respectively. Gorontalo Pluton emplaced at temperatures of 662 - 668°C with the pressure range from 2.6 to 2.7 kbar, is equivalent to 9.3 km deep. Varied oxidation state (ranging from -14 to 19) is inferred from the mineral assemblages, showing a strong association with highly oxidized I-type series granitic rocks. The exhumation rate estimation shows that Mamasa and Masamba Plutons were exhumed respectively at a rate of 0.37 and 1.6 mm/year, whereas Lalos-Toli and Sony Plutons at 1.4 and 2.7 mm/year, respectively. Gorontalo Pluton located in the Northern Sulawesi Province was exhumed at 0.42 mm/year. The rapid exhumation rate of Sony Pluton is attributed to the active vertical movement of Palu-Koro Fault Zone which has been active since Pliocene. It shows that faulting may play an important role in differential exhumation of intrusive bodies in the orogenic belt.

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

Penyebaran penyakit menular dan infeksi seperti COVID-19 dapat memberikan dampak yang signifikan terhadap kesehatan masyarakat dan perekonomian dunia. Organisasi Kesehatan Dunia atau WHO secara resmi memberi nama wabah ini COVID-19, dan virus tersebut dinamakan SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). Pada tanggal 30 Januari 2020 WHO mendeklarasikan darurat kesehatan masyarakat yang menjadi perhatian global (PHEIC). Pada 20 September 2020 di Indonesia terdapat 240.687 kasus positif dan kematian sebanyak 9.448 orang. Standar deteksi Covid 19 adalah melalui tes PCR (polymerase chain reacting), yaitu dengan mendeteksi keberadaan materi genetik virus SARS-CoV-2 pada lendir atau cairan saluran nasofaring. Namun hasil tes PCR SARS-CoV-2 baru akan diketahui dalam waktu yang cukup lama. Hingga saat ini, penyakit virus corona baru (coronavirus) telah menyebabkan krisis kesehatan global, dan industri medis sedang mengembangkan solusi inovatif untuk mengendalikan pandemi penyakit virus corona (corona virus) dan menghentikan penyebarannya. Kami terus mengeksplorasi inovasi teknologi di bidang kesehatan untuk membantu masyarakat dalam diagnosis COVID-19. Kecerdasan buatan (AI) adalah teknologi yang dapat dengan mudah digunakan untuk melacak penyebaran virus ini, mengidentifikasi pasien, dan mengendalikan infeksi ini secara real time. AI dapat berkontribusi melalui skrining populasi, medis, notifikasi, dan saran pada mengendalikan penyebarannya secara efektif. Oleh karena itu, jurnal ini bertujuan untuk merancang mockup user interface untuk diagnosis penyakit menggunakan pencitraan medis berbasis Artificial Intelligence (AI), khususnya dalam mendeteksi infeksi COVID-19 dengan metode pengembangan Waterfall.

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.
