Abstract

Based on trace geological history and several studies, the Sangiran mud volcano provides insight into the geology and hydrology of the region, aquifer system in the basin, groundwater flow patterns and characteristics, rock lithology, hydrogeology condition, and saltwater trap mapping. Related to these conditions, studies were conducted on the magnetic content and composition of the major oxide compounds in the Sangiran sediments. Sample analysis was based on geochemical methods. The methods consist of frequency dependent magnetic susceptibility and vibrating sample magnetometer (VSM) analysis. Geochemical analyses using x-ray fluorescence (XRF) analysis have been conducted and various elemental grades have been determined. VSM results confirm that the magnetic content of Sangiran sediments is partly dominated by Fe (17.66 percent) contained in hematite (Fe2O3). At the same time, the samples of Sangiran sediment were enriched by Si, Fe, Al, Ca, Cl, Ti, and K according to XRF measurements. The samples exhibited the highest Si and Fe concentrations in samples T1 (Si is 29.48 percent and Fe is 13.66 percent) and T7 (Si is 24.95 percent and Fe is 12.01 percent). Meanwhile, in the T4 sample, the highest concentrations were Si and Ca, 23.45 percent and 13.45 percent, respectively. Retrieved from the magnetic susceptibility measurement, this paper confirm that Fe content is one of the components of volcanic ash in the Sangiran sediment.DOI: 10.17977/um024v8i12023p009

Abstract

Juvenile delinquency (such as smoking, drug use, and acts of bullying) is prone to occur after the COVID-19 pandemic and during digitalization, including students in Islamic-based schools. This study aims to examine the perceptions and attitudes of Islamic school students towards smoking, drugs, and bullying, the demographic differences, and the relationship between these variables. The survey was conducted by distributing 26 questions to 94 Islamic school students. Data were processed using descriptive analysis, comparative (t test and ANOVA) and correlation (pearson correlation test). The results showed that almost half of the students had smoked with the male predominance. Perception toward smoking, attitude towards drugs, and bullying were good in each group; shows the contribution of Islamic education to juvenile delinquency. However, perception towards cigarettes and drugs were significantly higher in the upper grade and anti-bullying attitudes were also significantly higher in the group of students who had never smoked. Based on the results of this study, perception towards smoking, attitude towards drugs, and bullying are interrelated so that handling one variable of juvenile delinquency can have an impact on other variables.

Abstract

Indonesia is a country with a high frequency of natural disasters due to its location in the tropics and along the pacific ring of fire. Its diverse topography, characterized by numerous mountains and coastal areas, significantly influences land slopes. One common disaster associated with slope differences is landslides-mass movements of soil triggered by various factors, one of which is the steepness of the slope. Cianjur Regency is among the regions with a high risk of landslides. According to data from the West Java Regional Disaster Management Agency (BNPB), Cianjur experiences more than 90 landslides annually. Therefore, mitigation efforts must be carried out based on landslide risk mapping in this region. The purpose of this research is to identify and map landslide-prone areas in Cianjur Regency. Mapping results from 2018 to 2023 indicate that areas with the highest landslide risk are concentrated in northern Cianjur, particularly in the districts of Cugenang, Cipanas, Sukaresmi, and surrounding areas. Mitigation efforts should be prioritized in these districts without neglecting other areas. In addition to the 2018–2023 mapping, a 2025 prediction map can also be developed to guide broader and more comprehensive mitigation efforts, which still indicate a very high risk in northern Cianjur. Furthermore, mapping using the SMORPH method has produced results that closely align with both the annual and predictive mapping approaches, reinforcing the validity of the identified high-risk zones.

Abstract

This study investigates the impact of vehicular emissions on the physico-chemical properties of topsoil at Padjadjaran University, Jatinangor. Soil samples were analyzed for pH, electrical conductivity (EC), total dissolved solids (TDS), magnetic susceptibility ()LFll, magnetic domain properties (), and heavy metal concentrations using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). The results showed that while pH values remained within the neutral range (6.03–7.40), elevated EC and TDS values were observed at locations with high traffic density, indicating increased ionic content from anthropogenic sources. Magnetic susceptibility values ranged from 506.7 to 1148.7 × 10⁻⁸ m³kg⁻¹, with all sites exceeding 10 × 10⁻⁸ m³kg⁻¹, confirming the presence of ferrimagnetic minerals, and higher values were found near areas with heavy vehicle activity. The ) values, mostly below 4%, suggest a significant contribution from anthropogenic magnetic particles, dominated by stable single domain (SSD) and multi domain (MD) grains. Heavy metal analysis revealed that most elements (Fe, Mn, Cu, Zn, Al, As, Mg, Ca, K, Ni and Cr) were within permissible limits, except cadmium (Cd), which exceeded background crustal levels, suggesting contamination from anthropogenic sources, including vehicle emissions.

Abstract

Sarimukti landfill serves as a waste disposal site. Leachate generated from waste accumulation is discharged through pipelines into multiple retention ponds. This study aims to assess contamination levels in leachate deposits by analyzing the magnetic properties and morphology of magnetic minerals collected from four retention ponds, along with measurements of pH, EC, and TDS in the pond water. Magnetic susceptibility values range from 37.4 – 409.5 (×10⁻⁸) m³/kg, indicating ferrimagnetic mineral dominance. The  values range from 0.81% - 5.96%, where  >2% is often associated to pollutant-contaminated soils. A negative correlation between  and  suggests a minor contribution of superparamagnetic grains from pedogenesis. Scanning Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS) analysis identifies spherule and hedral magnetic mineral shapes, with O and Fe as dominant elements and minor Ti, indicating magnetite and titanomagnetite presence. Other elements, including C, Mg, Al, Si, K, Ca, and Mn, likely originate from anthropogenic sources.

Abstract

The Ciuyah Mud Volcano in West Java is a notable geological feature resulting from mud extrusion driven by subsurface pressure, buoyancy, and thermal variations. Its unique characteristics provide valuable insights into Earth's subsurface processes. Materials ejected from mud volcanoes often contain valuable minerals that are crucial for scientific investigation and economic application. Of particular interest at this site is the presence of Rare Earth Elements (REEs), which are vital for modern technology. The aim of this study is to provide a comprehensive characterisation of the Ciuyah Mud Volcano. The objectives are to: (1) determine its physicochemical properties using electrical conductivity (EC), volumetric water content (VWC), and total dissolved solids (TDS) measurements; (2) identify the distribution of REEs using X-Ray Fluorescence (XRF) and Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES); and (3) analyze the salt mineralogy using Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). The results revealed high conductivity in the mud, as evidenced by elevated EC and VWC values, as well as high TDS and salinity in the water samples. XRF and ICP-OES analyses confirmed the presence of twelve REEs: Ce, Dy, Eu, Gd, Ho, La, Nd, Pr, Sm, Tb, Sc, and Y. Furthermore, SEM and XRD identified Halite and Helvite as the primary salt minerals, characterized by large, hexagonal crystal structures. These findings highlight the potential of the Ciuyah Mud Volcano as a source of strategic REEs for Indonesia’s advanced materials and clean energy sectors, while also offering local socioeconomic applications, such as salt-based cosmetic products.
