Social Problems and Threats of Digital Technologies Based on Artificial Intelligence
Get PDFThe problems of interaction between humans and digital technologies based on artificial intelligence cannot be regarded as resolved. The aim of this study is, through the generalisation of various viewpoints on the interaction between humans and artificial intelligence, to find an answer to the question of whether the digital revolution represents another, albeit radical, improvement in human life, one that may nevertheless displace humans from the pinnacle of evolution, or whether it constitutes something that is destined to replace humans altogether. The following methods were employed: logical analysis, observation, sociocultural analysis, synthesis, comparison, induction, forecasting, and generalisation. The results obtained indicate that three key problems in the interaction between humans and artificial intelligence have been identified. First, there is a declining human capacity to control digital technologies due to their revolutionary development. Second, there is an incorrect assessment of, or even a complete disregard for, the negative consequences of the total digitalisation of all spheres of life. Third, humans tend to overestimate their ability to control digital technologies based on artificial intelligence. In order to ensure further interaction between humans and the artificial intelligence they have created, the study proposes measures aimed at counteracting the criminalisation of artificial intelligence
Watershed Morphometric Controls on Highland Flooding in Enrekang’s Urban Area
Get PDFThe earth's surface is completely divided by watersheds; urban and rural areas are sub-systems of watersheds. Flooding is influenced by climatic aspects, LULC, and morphometric characteristics. The Enrekang urban area is in the highlands. However, when it rains with high intensity, the area experiences flooding that causes social, economic, and environmental losses. This study aims to identify watersheds and reveal the morphometric factors of watersheds in the upstream part of the Enrekang urban area. The data used is NASADEM as a modernization DEM from SRTM, processed by spatial analysis techniques and mathematical calculations on the linear, areal, and relief aspects of the watershed. Data shows that in the Enrekang urban area, there is a confluence of the main stream (seventh-sixth order) from the upstream Saddang sub-watershed (SW-2) with the Mataallo sub-watershed (SW-3). In addition, the Rbm value of 2 is an extreme classification. High ruggedness number indicates steep slopes, and thus resulting in flash floods and erosion. In terms of area, the area of water catchment in the sub-watershed upstream of urban areas is 5,930.77 sq.km., the area is classified as a large watershed. A large catchment area will produce a large flood discharge. Factors of land use change in the upstream part, triggering an increase in surface runoff. There are three district capitals located upstream of Saddang watershed which causes the conversion of green land into built areas due to the need for housing and public facilities. This data can be a reference for the government, academics, and the community for the purpose of planning flood control programs in upstream of the Enrekang Urban Area
Colloidal TiO2 Nanoparticles Synthesized via Pulsed Laser Ablation in Liquid for Photocatalytic Degradation of Rhodamine B
Get PDFColloidal TiO2 nanoparticles were synthesized via pulsed laser ablation in liquid (PLAL) method using a Q-switched Nd:YAG laser operating at 1064 nm. The optical and structural properties were analyzed using UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), and selected area diffraction (SAED). The amorphous TiO2 colloids exhibited a distinct absorption edge in the UV region, with the optical bandgap (Eg) estimated by the Tauc plot to be approximately 3.75 eV. Photocatalytic activity was evaluated through the degradation of Rhodamine B (10 ppm) under UV lamp (254 nm) irradiation. The TiO2 photocatalyst achieved more than 75% degradation within 150 minutes, whereas the control (photolysis without catalyst) showed less than 5% degradation. These results demonstrate that PLAL enables a clean and straightforward synthesis of high-purity amorphous TiO2 nanoparticles with effective photocatalytic activity under UV irradiation
Developing 1-D velocity model along Matano Fault Zone, Sulawesi, Indonesia
Get PDFThe Matano Fault, with a slip rate of ~ 20 mm/year, is the most active strike-slip fault in Sulawesi after the Palu-Koro Fault. As a result, this region exhibits a high level of seismicity. Unfortunately, a number of studies that have been conducted only involve a less dense network of stations and global velocity models. This study aims to obtain an optimum velocity model using the VELEST program, which reliably represents the actual condition of the study area. The data used in this study consists of hypocenter, origin times, and P-wave arrival times from earthquakes (Mw ≥ 3), each containing at least six clearly identified P-wave phases. These data were obtained from 317 events that occurred within the region bounded by 120.10°E – 122.20°E and 2.99°S – 1.66°S during the period from January 2022 to March 2025. To determine the optimum 1-D velocity model, four initial models were tested, namely Koulakov, Arimuko, Crust, and Bunaga. These models were evaluated based on RMS, the stability test of the updated velocity model, uncertainty assessment using bootstrap test, and their consistency with previous studies. The evaluation results indicate that the Arimuko Model is the most reliable, as it provides the lowest RMS value, stable hypocenter relocations (±6–7 km), bootstrap results showing narrow uncertainty intervals, and consistency with earlier studies that identified a low-velocity zone at depths of 0–3 km. The result of this study is expected to serve as a reference for earthquake relocation and seismicity analysis at the Matano Fault Zone
