Beyond Site Effects: Azimuthal Dependence of Ground Motion Residuals in the Volcanic Arc and Sedimentary Basins of West Java, Indonesia
type: item
description: The complex tectonic setting of West Java, characterized by the interaction between the Sunda volcanic arc and deep sedimentary basins, presents significant challenges for seismic hazard assessment. This study recalibrates a local Ground Motion Prediction Equation (GMPE) using a hybrid regression strategy to isolate non-ergodic path effects. We implemented a constrained regression for Site Class C fixing the saturation parameter d = 5.80 to match the Class D baseline and applied site-term corrections for Class B. Our results reveal a weak correlation between residuals and (R = 0.215), suggesting that shallow soil velocity is a suboptimal proxy for ground motion variability in this region. Instead, a distinct azimuthal anisotropy emerged, characterized by a dipolar residual pattern. Significant high-frequency attenuation (negative residuals) was identified in azimuths crossing the Quaternary Volcanic Arc, likely driven by multiple scattering in fractured magmatic media. Conversely, systematic amplification (positive residuals) was observed towards the Jakarta and Bandung Basins, consistent with deep basin resonance. These findings underscore the necessity of integrating azimuthal path terms into regional hazard models. Moving beyond 1D site-effect proxies is critical for enhancing the accuracy of Earthquake Early Warning (EEW) systems and urban seismic mitigation in West Java’s densely populated basins.

Seismic Site Characterization Using Horizontal-to-Vertical Spectral Ratio (HVSR) Analysis of Ambient Noise at Sukasari Village, Sumedang, West Java
type: item
description: Local geological conditions can significantly influence seismic wave amplification during earthquakes, particularly in regions composed of unconsolidated volcanic deposits. This study aims to characterize the seismic site conditions of Sukasari Village, Sumedang Regency, West Java, using the Horizontal-to-Vertical Spectral Ratio (HVSR) method based on ambient seismic noise measurements. A total of 72 microtremor measurement points were distributed across the study area to capture spatial variations in near-surface geological conditions. HVSR analysis was conducted to determine key parameters, including dominant frequency (), amplification factor (), dominant period (), and the seismic vulnerability index (). The results show that values range from 1.1 to 19.1 Hz, ranges from 0.058 to 1.788 s, ranges from 1.4 to 7.3, and ranges from 1.0 to 22.8, indicating significant variations in sediment thickness and subsurface stiffness across the study area. Areas characterized by low values and high and are associated with thick unconsolidated sediments that have a higher potential for seismic wave amplification, whereas areas with high F₀ and low Kg correspond to compact volcanic formations with relatively stable ground conditions. These findings demonstrate that the HVSR method effectively identifies spatial variations in local site response and provides important information for seismic microzonation and earthquake-resilient land-use planning in Sukasari Village.

Enhancing Stratigraphic Geomodelling through Integration of Relative Geological Time and Spectral Decomposition: A Case Study from the Volve Field
type: item
description: This study aims to enhance stratigraphic interpretation and geomodel construction through the integration of Relative Geological Time (RGT) and spectral decomposition in the Volve Field, North Sea. Conventional seismic interpretation often faces limitations in identifying subtle stratigraphic features such as channels and thin layers due to limited vertical resolution. To address this issue, RGT was applied to generate a stratigraphic framework with dense horizons based on relative geological time, followed by spectral decomposition using Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) to improve vertical resolution and delineate depositional features. The results show that the RGT-based stratigraphic framework successfully identified major horizons from Jurassic to Cenozoic intervals, highlighting depositional evolution within the study area. Spectral decomposition analysis at selected frequencies revealed sinuous channel geometries within the Sleipner and Hugin formations. Comparison between methods indicates that STFT provides more laterally continuous channel delineation, while CWT is more sensitive to local amplitude variations. RGB blending further enhanced visualization of channel features and improved geobody extraction. The integrated interpretation produced a three-dimensional geomodel of channel geobodies, indicating fluvio-deltaic to shallow marine depositional systems with significant lateral heterogeneity. This study demonstrates that integrating RGT and spectral decomposition improves stratigraphic interpretation, enhances geobody delineation, and reduces uncertainty in reservoir characterization. The proposed workflow can be applied to other complex depositional systems to improve stratigraphic geomodeling and reservoir analysis.

Nutmeg Oil as an Anesthetic for Enhanced Gas Diffusion in High-Density Seabass Seedlings
type: item
description: Asian seabass (Lates calcarifer) is a high-value aquaculture species cultivated to supply domestic and export markets. However, water quality deterioration during transport—marked by declining dissolved oxygen (DO) and rising carbon dioxide (CO₂) levels due to increased fish respiration and limited gas diffusion governed by Henry's Law—can induce stress and reduce seed survival. This study aimed to evaluate the effect of nutmeg oil (Myristica fragrans Houtt.) as an anesthetic on the survival and physiological response of Asian seabass seeds transported at different stocking densities, and to determine the optimal density for wet closed-system transportation. The experiment, conducted in February 2025 at the Faculty of Marine and Fisheries, Syiah Kuala University, employed a completely randomized design with five treatments and four replications. Treatments included a control (without anesthetic) and nutmeg oil administration (1.0 ppm) at densities of 25, 35, 45, and 55 fish. Transportation lasted for eight hours. Nutmeg oil significantly affected anesthesia induction and recovery time (P<0.05) but had no significant effect on survival (P>0.05). The highest survival rate (98.88%) was observed at 45 fish per container with 1.0 ppm nutmeg oil. The findings suggest nutmeg oil is an effective natural anesthetic for improving transport efficiency and fish welfare, supporting SDG 14 (Life Below Water) through sustainable aquaculture practices.

Soil Physics Analysis of pH and Water Retention Capacity in Productive Paddy Fields and Soils Degraded by Waste-Burning Residues
type: item
description: This study investigated the differences in soil pH and water retention capacity between productive paddy soil and soil degraded by waste combustion residues from a soil physics perspective. The waste combustion soil used was household waste combustion soil containing organic and inorganic waste. Combustion residues can alter the physicochemical properties of the soil, particularly porosity, capillarity, and moisture dynamics, which affect soil water retention behavior. A comparative quantitative approach was used by collecting soil samples at a depth of 0–20 cm from two different locations. Soil pH was measured using a digital pH meter, while water retention capacity was analyzed using standard laboratory procedures. The results showed that the productive paddy soil exhibited a pH close to neutral (6.8), higher porosity, stronger capillary action, and high water retention capacity (90%). In contrast, the degraded soil exhibited alkaline conditions (pH 8.7), reduced pore connectivity, impaired moisture dynamics, and lower water retention capacity (60%). These findings suggest that waste combustion residues negatively impact soil structure and water retention mechanisms. Therefore, appropriate waste management and soil rehabilitation strategies are needed to restore soil function and agricultural productivity.

Mapping of Physicochemical Properties of Well and River Water in Sayang and Cikeruh Villages, Sumedang Regency
type: item
description: Water is an essential resource for human life, yet its quality has declined due to population growth and land-use changes. Sayang and Cikeruh Villages in Jatinangor District have experienced environmental pressures from land conversion and domestic activities that may affect groundwater and surface water quality. This study aims to map and analyze the physicochemical parameters of water, including temperature, pH, electrical conductivity (EC), and total dissolved solids (TDS), in well water and the Cikeruh River. Measurements were conducted at ten well and nine river sampling points and analyzed using descriptive, spatial, and multivariate methods. The results show that most well water samples meet clean water quality criteria; however, several locations exhibit elevated EC and TDS values and slightly acidic pH, indicating the influence of surrounding residential activities. In contrast, river water quality remains within acceptable limits for all measured parameters. Multivariate analysis reveals a strong correlation between EC and TDS in both well and river water, indicating their importance as key indicators of water quality. Spatial analysis shows that water quality in the southern part of the study area tends to be lower than in the northern part. Continuous monitoring and appropriate water resource management are therefore necessary to maintain water quality in the study area.

Identification of Agricultural Suitability Zones and Groundwater Contamination Using Geoelectrical and Soil Physicochemical Analysis in Sukasari Village, West Java, Indonesia
type: item
description: Soil and groundwater pollution from anthropogenic activities poses a significant challenge to agricultural sustainability in rural areas, including Sukasari Village, Tanjungsari District, Sumedang Regency. This study aims to delineate contaminated zones and characterize contaminant distribution patterns through the integration of geoelectrical methods and soil physicochemical analysis. The geoelectrical survey was conducted along eight lines using a 48 electrode configuration with 1 meter spacing. The resistivity cross-sections revealed high-resistivity anomalies in the garden area located downslope of the settlement, indicating contaminant accumulation. This finding was supported by soil test results that confirmed the presence of pollutants, while the area around the biodigester remained relatively uncontaminated. The results indicate that the primary sources of contamination are household and agricultural activities in the southern settlement area, with contaminant migration toward the gardens and rice fields in the north. Overall, this study demonstrates that integrating geoelectrical methods and soil physicochemical analysis is an effective approach for mapping subsurface contamination and supporting sustainable agricultural land management.

The Influence of the Contextual Teaching and Learning (CTL) Model Based on Local Wisdom on Students' Physics Learning Outcomes at SMAN 8 Banda Aceh
type: item
description: Low physics learning outcomes in high school are often caused by teacher-centered learning that does not relate the material to real life or local culture. This study aims to determine the effect of the contextual teaching and learning (CTL) model based on local wisdom on the physics learning outcomes of students at SMAN 8 Banda Aceh. The population of this study was all 10th grade IPAS students, using random sampling. Grade X IPAS 2 became the research sample. Data were collected through learning outcome tests and observations. Data analysis used normality tests (Shapiro Wilk), N-Gain tests, and t-tests (paired sample tests). The average pretest score was 23.1, while the average posttest score was 83.83. Furthermore, the results of the hypothesis test using the t-test showed that tcount ≥ ttable (5.45 ≥ 1.699) (α = 0.05), so it was concluded that the contextual teaching and learning (CTL) model based on local wisdom had a significant effect on improving students’ physics learning outcomes. Observations of the implementation of the first meeting reached 88.812 and the second meeting reached 88.49, indicating that students were more motivated and understood the concepts better. Thus, contextual teaching and learning (CTL) based on local wisdom effectively improves students’ physics learning outcomes.

Effects of the ARCS Instructional Model on Undergraduate Students’ Motivation and Learning Outcomes in an Online Basic Physics Course
type: item
description: This study investigates the effectiveness of the ARCS motivational model (Attention, Relevance, Confidence, Satisfaction) in improving undergraduate students’ motivation and learning outcomes in an online Basic Physics course. A one‑shot case study design was employed with a single cohort of students (n = 37). Learning motivation was measured using a validated ARCS‑based questionnaire, while learning outcomes were assessed through a post‑test aligned with four Sub‑CPMK indicators. Descriptive statistics and the Wilcoxon signed‑rank test were used to analyze the data. The Wilcoxon test compared students’ post‑test scores against the predetermined minimum competency standard (KKM = 70). Results showed generally high levels of motivation across most indicators (61.95%–80.26%), although engaging learning activities fell within the moderate category (53.78%). Learning outcomes varied substantially, with the highest performance recorded in Sub‑CPMK 3 (analyzing motion through data, graphs, and equations) at 83.2%, and the lowest in Sub‑CPMK 2 (vector analysis and dipole moment concepts) at 14.6%. The Wilcoxon signed‑rank test yielded a significant result (p = 0.000), indicating that student performance significantly exceeded the KKM benchmark. These findings suggest that the ARCS model effectively enhances motivation and conceptual understanding, particularly for visually representable content, while highlighting the need for additional instructional scaffolding (e.g., progressive visual support and guided practice) to improve learning of abstract concepts such as vectors and dipole moments. Future research is recommended to employ stronger experimental controls (e.g., pretest‑posttest control group designs) and item‑level analyses to further validate the applicability of the ARCS model in online physics education.

An Indirect Measurement of the Speed of Light Using EMF Meter
type: item
description: This research aims to measure indirectly the speed of light using EMF meter. An EMF meter is a device to measure separately magnetic and electromagnetic field sources. In this research we use 44 different smartphones as the sources and calculate the speed of light using ratio of magnetic field to electromagnetic field (c=E/B). Standard deviation or relative error is also calculated to make sure the speed of light measured is within the range speed of light in vacuum which is 3 x 108 m/s. This method provides relatively straightforward method way to determine speed of light. In this measurement, we find the speed of light is 3.21 x 108 m/s. However, there is an anomaly with the data due to standard deviation higher than the speed of light. This anomaly caused by high variability of data, strong outlier and right skew distribution which has relation to uncalibarated device. By reducing the accepted speed of light data measurement between 2 x 108 m/s - 5 x 108 m/s we then obtain the speed of light 3.22 x108 m/s and the standard deviation is 0.85 x 108 m/s.

Design of Parabolic Motion Simulation Using R for Physics Learning
type: item
description: Students’ understanding of parabolic motion remains low due to the abstract nature of the concept and the limited use of effective visualization media in learning. This study aims to develop an interactive learning medium in the form of a parabolic motion simulation using the R programming language with the R-Shiny framework, as well as to evaluate its feasibility through expert validation. This research adopts the Research and Development (R&D) method with the Alessi and Trollip model, which includes planning, design, and development stages. The novelty of this study lies in the integration of the R-Shiny framework into physics learning, which is still rarely utilized, particularly for developing interactive simulations at the higher education level. The developed simulation enables dynamic visualization of projectile motion and facilitates exploration of relationships between key variables. The validation results show an Aiken’s V value of 0.99 from media experts and 0.94 from subject matter experts, both categorized as highly valid. These findings indicate that the developed simulation is feasible and effective as an interactive learning medium. It contributes to physics education by enhancing conceptual understanding, promoting active learning, and providing an accessible platform for visualizing two-dimensional kinematics.

Evaluating Assessment Instruments for Measuring Students’ Higher-Order Thinking Skills in Heat and Temperature Concepts
type: item
description: This study aimed to develop a higher-order thinking skills (HOTS)–based test instrument on temperature and heat topics and to examine its initial quality and feasibility as an assessment tool. The research employed a research and development (R&D) approach using the Borg and Gall model, which included stages of potential problem identification, information collection, product design, expert validation, product revision, and limited field testing. Expert validation using Aiken’s V yielded coefficients ranging from 0.82 to 0.94, indicating strong content validity. The limited field trial involved 32 ninth-grade students, and data analysis was conducted using Microsoft Excel and IBM SPSS Statistics 25. Empirical validity testing showed that 23 out of 40 items (57.5%) met the validity criterion, while the remaining items required revision or elimination. Reliability analysis using the KR-20 formula produced a coefficient of 0.776, indicating high internal consistency. Analysis of item difficulty revealed that 10 items (25%) were classified as difficult and 30 items (75%) as moderately difficult. Furthermore, the discriminating power analysis indicated that only 10 items (25%) demonstrated good discrimination, while 15 items (37.5%) fell into the sufficient category, suggesting that several items require further refinement to better differentiate students’ ability levels. Overall, the findings indicate that the developed HOTS-based test instrument demonstrates preliminary quality and conditional feasibility for measuring students’ higher-order thinking skills in junior high school science learning on temperature and heat topics. However, substantial revisions—particularly to improve item discrimination and increase the proportion of valid items—are necessary before the instrument can be recommended for broader implementation.

The Effect of Deep Learning-Based Contextual Problem on Science Concept Understanding in Slow Learners at Inclusive Schools
type: item
description: Exploring deep learning in inclusive schools is urgent, as it plays a crucial role in fostering meaningful learning experiences for students with diverse abilities. This study aims to determine the effect of deep learning based contextual problem on science concept understanding among slow learners in inclusive schools. The research method used is a quasi-experimental design with a pretest-posttest control group design, involving two inclusive classes in the Yogyakarta region. One class served as the experimental group and received deep learning based contextual problem treatment for three weeks, while the control class received conventional instruction. The main instruments were multiple-choice tests to measure understanding of ecosystem concepts, as well as observation sheets of learning activities. The results of the analysis using the Mann-Whitney test showed a significant difference between the experimental and control groups (p = 0.000), indicating that this approach is effective in improving science concept understanding among slow learners. Learning was conducted through stages of understanding, application, and reflection, utilizing contextual media, field trips, and environmental management projects that involved the local community. These findings reinforce the relevance of constructivism, situated learning, and experiential learning theories in inclusive education. In addition to supporting cognitive aspects, this model also contributes to students' social skills and learning motivation. The practical implications of this study encourage teachers to apply adaptive and contextual learning strategies, as well as the importance of developing modules and teacher training.

Physico-Chemical and Magnetic Characterization of Topsoil Influenced by Vehicular Emissions at Padjadjaran University, Jatinangor
type: item
description: 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.

Effect of Aluminium Plate Layers and Electric Current on Pendulum Damping Time
type: item
description: The pendulum is a classic oscillatory system commonly used in physics to study motion and damping phenomena. One notable damping mechanism is electromagnetic damping caused by eddy current induction. This study investigates the effects of varying the number of aluminium plate layers attached to the pendulum and the electric current supplied to a surrounding coil, which generates a magnetic field, on the pendulum damping time. An experimental approach was used by measuring the damping time across different combinations of plate layers and current levels. The data were analyzed to identify the relationship between these variables and the damping behavior of the pendulum. Results indicate a negative exponential relationship between the electric current and damping time, as well as a significant effect of aluminium plate layers on damping efficiency. Increasing the number of aluminium plate layers enhances eddy current induction, resulting in stronger damping forces.

Many students still have difficulty understanding and relating physics concepts to phenomena found in the Waterpark’s attractions. As a solution, an enrichment book based on Problem-Based Learning was developed, presenting contextual problems related to physics phenomena at the Waterpark to help students better understand concepts in a real context. The book was validated by experts before testing its practicality and effectiveness in learning. This study aims to produce an enrichment book, Edupark Physics Batang Tabik Waterpark, based on PBL that meets practical and effective criteria. The quantitative research method used a one-group pretest-posttest design, with purposive sampling of class XI-2 from the XI Fase F population at SMAN 1 Sarolangun, as this class applies the Problem-Based Learning model. Instruments included questionnaires for practicality testing and multiple-choice C2 level tests to measure conceptual understanding. Data were analyzed using percentage and paired sample t-test. The results showed that the enrichment book is highly practical (average score 92.58%) and effectively improves students’ physics concept understanding significantly (p < 0.001).

Effectiveness of Integration of Exit Slips Formative Assessment in Problem Based Learning in Improving Critical Thinking Skills of High School Students on Heat Material
type: item
description: This study was motivated by the need to address the lack of critical thinking skills among students in order to meet the demands of the 21st century. The purpose of this study was to demonstrate the effectiveness of integrating formative assessment in the form of Exit Slips into problem-based learning to improve students' critical thinking skills related to current issues. The research design used was quasi-experimental with matching only pretest posttest control group, involving 69 eleventh-grade students in Bandung. Data were collected using the ACTA test for critical thinking, formative assessment called Exit Slips, and student questionnaires. Data analysis was conducted using the N-Gain test, effect size, and quantitative descriptive analysis. The results of the study showed a significant difference in the improvement of critical thinking skills between the experimental group and the control group, with N-Gain values in the moderate category and effect sizes in the high category. Student responses to the integration of Exit Slips formative assessment into problem based learning were also in the good category. Overall, the integration of Exit Slips formative assessment into problem-based learning was highly effective in improving critical thinking skills.

High-Accuracy Pneumonia Classification via Ensemble Learning on Chest X-ray Imagery
type: item
description: Pneumonia continues to pose a substantial global health threat, necessitating rapid and precise diagnostic tools. The conventional manual assessment of Chest X-ray (CXR) images is time-intensive and susceptible to human error. This study introduces an automated machine learning approach that employs an ensemble learning strategy to achieve highly accurate pneumonia classification from CXR images. The comprehensive system operates through three primary phases: initial image pre-processing (involving grayscale conversion, resizing, and filtering for enhanced quality), robust feature extraction (utilizing the fusion of Histogram of Oriented Gradients (HOG) and Local Binary Pattern (LBP) descriptors), and sophisticated model training and classification. An ensemble model is trained, integrating the predictive power of Random Forest, Logistic Regression, and Extreme Gradient Boosting classifiers. Experimental validations, performed on a dedicated dataset comprising pneumonia and normal CXR images, unequivocally demonstrate that the proposed strategy achieves an impressive 97.50% overall classification accuracy, strongly supported by precision, recall, and F1-scores all at 97.50%. This superior performance, notably surpassing individual machine learning algorithms, underscores the profound efficacy of ensemble learning in delivering reliable and precise predictions for pneumonia diagnosis. Consequently, this automated methodology presents a valuable asset for medical professionals, aiding in the swift and accurate identification of pneumonia.

Project Based Learning in Science Education Research in Indonesia: A Bibliometric Analysis
type: item
description: Project-based learning (PjBL) is increasingly recognised in science education in Indonesia as a strategy to improve students' higher order thinking skills and real-world problem solving. This article analyses the trends and patterns of PjBL research in Indonesia from 2020 to 2024 using a bibliometric approach. Research data were collected from Google Scholar, Crossref, and OpenAlex databases, then analysed descriptively qualitatively and visualised using VOSviewer. The results of the analysis showed that the majority of studies were experimental (68.36%), focusing on evaluating the effectiveness of PjBL in improving learning outcomes and critical thinking skills, particularly in the context of higher education and digital technology integration. The implementation of PjBL is considered effective in fostering students' creativity, motivation and 21st century competencies. However, there are still implementation challenges that require further study. Based on these findings, it is concluded that PjBL has great potential as a key approach in the Indonesian science curriculum. Therefore, further studies are needed to optimise its effectiveness and overcome the existing obstacles.
