Identification of Agricultural Suitability Zones and Groundwater Contamination Using Geoelectrical and Soil Physicochemical Analysis in Sukasari Village, West Java, Indonesia
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
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.

An Indirect Measurement of the Speed of Light Using EMF Meter
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.

Evaluating Assessment Instruments for Measuring Students’ Higher-Order Thinking Skills in Heat and Temperature Concepts
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.

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

High-Accuracy Pneumonia Classification via Ensemble Learning on Chest X-ray Imagery
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.
