Abstract

The acoustic impedance inversion seismic method, carried out at the "EL" well in East Java,provides a description of the physical properties of subsurface rocks. This method involves identifying rocklayers, lithology types, porosity values, the presence of hydrocarbons, and fluids in the target zone usingboth well data and integrated seismic data. The data processing included the cross-plotting of acousticimpedance (AI) with gamma ray logs, porosity logs, and resistivity logs. We integrated seismic and welldata, picked horizons, and created AI inversion models. The based model inversion technique was used tocompare the synthetic model with the seismic data, aiming to obtain an AI value that closely represents theactual model. AI seismic inversion effectively separates lithological boundaries vertically and laterally,based on the selected picking horizon and created model. To enhance understanding of the lithology andhydrocarbon prospect zone in the study area, a cross-plot analysis was used to correlate the seismic inversionmodel. The results reveal that the study area represents a hydrocarbon prospect zone, with reservoir rocksconsist of coral and foram at a depth range of 2320 - 2430 ft.

Abstract

Kegiatan industri baja yang melibatkan peleburan besi dan baja dapat memicu adanya pencemaran tanah, karena dapat memproduksi limbah dalam bentuk debu dan fly ash yang menyebar terbawa angin lalu mengendap pada tanah permukaan. Dalam penelitian ini telah dilakukan identifikasi pencemaran tanah di kawasan sekitar perindustrian baja melalui parameter suseptibilitas magnetik dan pengukuran Scanning Electron Microscopy – Energy Dispersive X-Ray (SEM-EDX). Sampel yang digunakan yaitu berupa tanah yang diambil pada titik dari dua lintasan yaitu lintasan 1 dan lintasan 2. Dimana lintasan 2 di desain memiliki jarak yang lebih dekat dengan kawasan perindustrian dibandingkan lintasan 1. Nilai suseptibilitas magnetik (XLF) pada lintasan 1 berada pada rentang 96,9-854,1 (×10^-8 m^3/kg ) dan nilai XFD (%) yaitu 0,13-2,85, sedangkan XLF lintasan 2 berada pada rentang 194,7-3473,9 (×10^-8 m^3/kg) dan nilai XFD(%) yaitu 0,47-1,53. Hasil tersebut menujukkan bahwa nilai XLF pada lintasan 2 cenderung lebih tinggi daripada lintasan 1. Hal ini diduga bahwa limbah yang berupa debu maupun fly ash lebih banyak terakumulasi pada lintasan 2 yang areanya lebih dekat dengan perindustrian baja. Adapun nilai   XFD(%) dari seluruh sampel yang bernilai kurang dari 4% dan adanya korelasi negatif antara nilai XFD(%) dan XLF menunjukkan bahwa mineral magnetik berasal dari sumber antropogenik. Berdasarkan pengukuran SEM-EDX pada sampel di lintasan 1 menunjukkan bulir mineral magnetik yang berbentuk oktahedral dan bulat, yang menunjukkan keberadaan mineral magnetiknya berasal dari sumber pedogenik dan antropogenik. Sedangkan hasil SEM-EDX pada sampel di lintasan 2 menunjukkan keberadaan bulir mineral magnetik berbentuk bulat dan halus yang menunjukkan bahwa mineral megnetik berasal dari sumber antropogenik.

Abstract

Harmful substances deposited in the soil can disrupt soil functions, leading to environmental pollution and harm. Pesticides are one example of these harmful substances. Absorption of pesticides into the soil can lead to infertility and negatively impact overall soil health. Therefore, a study was conducted to identify pesticide-saturated soil near the surface and map the soil health conditions around Situ Cisanti. The research utilized geoelectric methods and collected soil and water samples from the inlet (a) and outlet (b) areas of Situ Cisanti. After conducting measurements around Situ Cisanti, the data collected include soil resistivity, ranging from 0.483 to 2.04 Ωm (a) and 658 to 2787 Ωm (b). Soil pH levels were 8.9 - 9.0 (a) and 8.9 (b). Soil Electrical Conductivity (EC) and Total Dissolved Solids (TDS) measured 250 - 280 μs and 194 - 207 ppm (a), and 240 μs and 178 ppm (b). Water pH was 7.7 (a) and 8.7 - 9.1 (b). Water EC and TDS were 100 μs and 83 ppm (a), and 80 - 180 μs and 65 - 94 ppm (b). The results indicated higher pesticide contamination in the outlet compared to the inlet, signifying potential risks to soil health.

Abstract

A high quantity of organic waste without proper waste management can endanger public health and environmental sustainability. To reduce the risk that can be caused by organic waste pollution, then there should be a solution. One of them is to make eco-enzyme. Eco-enzyme is a fermented solution from organic waste that can be used as floor cleaner, plant disinfectant, hand sanitiser, plant fertilizer, etc. A good eco-enzyme solution has special properties. One of them is the low-value power of Hydrogen (pH). In this study, other physical properties of eco-enzyme are analyzed. Eco-enzyme was produced from organic waste. Here, Sunkist orange peel and various mixtures of orange peel were used as the main materials of eco-enzyme. The eco-enzyme solutions were carried out for 33 days, accompanied by routine monitoring by reviewing physical parameters such as pH, Total Dissolved Solid (TDS), and Electrical Conductivity (EC) values. The results showed the characteristics of the eco-enzyme product by physical properties are the eco-enzyme has an acidic with a low pH value (<3.6) accompanied by high values of TDS (>1000 ppm) and EC (>1500mS/cm). The finding is TDS and EC have high value whereas usually high EC and TDS are owned by polluted liquids.

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.
