This research aims to develop a mathematics teaching module based on differentiated learning integrated with the Project-Based Learning (PjBL) method, specifically for the topic of spatial structures ("get up room") for students at Nanasi 1 Elementary School. The development process follows the 4D model, which includes the stages of Define, Design, Develop, and Disseminate. In the Define stage, analysis revealed the absence of instructional modules that align with students' learning styles and needs. Consequently, learning objectives were formulated based on geometric elements and problem-solving criteria. During the Design stage, a prototype module and validation instruments were produced. Validation was conducted by two experts, yielding high scores for both content and visual presentation—each achieving 90% validity. Practicality assessments also showed strong results, with content rated at 90.8% and visual aspects at 90%, categorizing the module as “very valid” and “very practical.” The integration of the PjBL method was implemented to enhance active student participation, encouraging collaborative exploration and real-world application of mathematical concepts. The developed module is considered suitable for supporting differentiated mathematics instruction in elementary schools. It accommodates diverse learning styles and promotes student engagement through project-based tasks. The findings suggest that combining differentiated learning with PjBL fosters a more inclusive and effective learning environment, particularly in geometry-related topics. This module not only meets pedagogical standards but also contributes to the advancement of innovative teaching practices in primary education.

The topic of Differentiated Instruction (DI) has recently been studied by researchers and practitioners due to its importance and potential to improve student learning. In this regard, the current study aims to provide a concise overview of DI in the context of EFL to illustrate the need for its implementation in the classroom to foster successful language learning. Since differentiated instruction is designed to place students at the centre of the teaching and learning process, promote equity and academic success, as well as recognize diversity among students, it enables teachers to address a student’s unique needs, interests, abilities, English proficiency, and preferred learning strategies. While challenges such as increased workload and implementation pressure in DI may arise, the potential benefits of this approach to students' learning processes, attitudes toward learning, and long-term success are notable. Therefore, the learning process is maximized when teachers are committed to differentiated instruction.

This school becomes the spot or role model for many other schools in Medan, therefore, the researcher intended to investigate further about the teaching model applied in this school, especially in EFL classroom in studying English. Some problems need to be answered after applying this study, such as how the English teachers manage the class to apply the DI, how is the students’ understanding about the subject after they applied DI

This study presents a machine learning approach for predicting the dimensions of microstrip antenna slots based on antenna performance parameters such as frequency, gain, directivity, return loss (S11), radiation efficiency, and VSWR. A two-phase methodology was employed. In the first phase, ten regression algorithms were evaluated, and Random Forest was identified as the most effective model based on Mean Absolute Error (MAE) and R-squared (R²) scores. In the second phase, hyperparameter tuning was conducted using Grid Search to further improve the model’s performance. The optimized Random Forest model demonstrated consistent improvements in predictive accuracy, with R² values increasing across all output variables. These results indicate that the combination of regression-based modeling and systematic hyperparameter tuning is effective for capturing complex relationships in antenna design tasks. The proposed approach offers a promising data-driven alternative for geometric prediction in microstrip antenna development, particularly when analytical models are insufficient.

Information technology is a technology used to manage data, including processing, acquiring, organizing, storing, and manipulating data in various ways to produce high-quality information—namely, information that is relevant, accurate, and timely. This information is used for personal, business, and governmental purposes, serving as strategic information in decision-making. To anticipate changes in weather conditions, particularly rainfall, a valid and accurate report is needed that can be useful for the public. So far, the correlation or relationship between the factors influencing weather conditions—especially rainfall—has not been precisely determined, making it mathematically difficult to create a model that can describe the correlation among all these factors. This is where Artificial Neural Networks (ANN) come into play: to create such models and map out the existing problems purely based on the input data provided. One of the capabilities of neural networks is to make predictions based on previously learned data using the backpropagation method.

This corpus-based study explores the acquisition patterns of English modal verbs by Indonesian EFL (English as a Foreign Language) learners through a comprehensive analysis of learner language data. The study utilizes a specialized learner corpus consisting of 2.5 million words drawn from both written and spoken productions of 450 Indonesian learners, covering various proficiency levels. The research focuses on examining the frequency patterns, semantic distributions, and error types associated with modal verb usage across the learner corpus. The study employs a combination of quantitative corpus linguistic methods and qualitative error analysis to uncover developmental trends and persistent difficulties in acquiring English modals. The findings highlight a significant underuse of epistemic modality, which expresses degrees of certainty, and an overreliance on core modals like "can," "will," and "must." Additionally, learners systematically avoid more complex modal constructions that are semantically nuanced and less frequent in their linguistic output. The analysis also reveals notable cross-linguistic influences from Indonesian, particularly in the areas of politeness marking and the expression of certainty. These interference patterns suggest that Indonesian learners may transfer modal expressions from their native language, leading to specific errors in the usage of English modals. Based on the findings, the study proposes a usage-based pedagogical framework that integrates corpus-informed instruction with explicit semantic mapping of modal meanings. This framework encourages teachers to address modal verb acquisition by emphasizing frequency-based approaches, contrastive semantic analysis, and corpus-driven awareness-raising activities. The research suggests that by focusing on the form-meaning-function relationships of modals in authentic contexts, learners can better understand and produce English modals accurately and appropriately. The findings have significant implications for enhancing modal verb instruction in EFL classrooms, especially for Indonesian learners.

The results of the study indicate that the implementation of the PAKEM model has a significant impact on increasing students' self-confidence through active, contextual, and fun learning activities. Teachers who are pedagogically sensitive are able to create an inclusive and supportive learning space, so that students feel valued and dare to express themselves. Despite obstacles such as time constraints, variations in student character, and a less than ideal teacher-student ratio, the PAKEM model still provides positive results in building learning motivation and restoring students' self-image. In conclusion, PAKEM is not just a learning method, but a transformative approach that is able to overcome students' psychological barriers and create a strong foundation of self-confidence to support children's academic success and character.

Mental health is a crucial aspect of modern life, with stress and anxiety being among the most common and impactful psychological disorders. This research proposes a stress and anxiety monitoring system based on the Internet of Things (IoT), integrating biometric sensors and Deep Neural Networks (DNN) for early detection and in-depth analysis. The system is designed using MAX30102 (heart rate and SpO₂), GSR (Galvanic Skin Response), and DS18B20 (body temperature) sensors, managed by an ESP32 microcontroller and communicating through the MQTT protocol. Physiological data is collected in real-time, formatted in JSON, and transmitted to both Android and web-based applications for visualization. The DNN model is developed using the TensorFlow framework with a layered architecture and ReLU activation functions to classify four mental states: relaxed, calm, anxious, and highly stressed. The training dataset comprises both primary and secondary data, including the WESAD dataset. Model performance is evaluated through k-fold cross-validation, showing high accuracy and strong generalization capabilities. The results indicate that the integration of sensor technology and deep learning significantly improves the effectiveness of stress and anxiety detection compared to traditional methods. This system demonstrates great potential for the development of AI-based wearable devices for autonomous, real-time, and adaptive mental health monitoring. 

This community service activity was carried out as an effort to improve the effectiveness of reporting and withholding of Income Tax (PPh) Article 21 at the Kosayu Credit Cooperative through accounting-based technical assistance. The main problem identified during the Field Work Practice (PKL) activity was the potential for tax overpayments caused by inaccurate estimates of employee annual income and limitations of the payroll system used by the cooperative. To address these problems, the implementation team implemented several methods, namely direct observation of the tax administration process, technical training for related staff, tax calculation simulations based on actual data, and evaluation of the existing tax recording and reporting system. The results of the activity showed that although the cooperative had used the Average Effective Rate (TER) method for withholding PPh 21, its implementation was still not optimal because it was not supported by an integrated information system and a regularly updated employee database. This resulted in inaccuracies in tax calculations and withholding. Therefore, this assistance recommended several improvements, including updating the payroll system, improving employee data, integrating the digital tax reporting system, and increasing the capacity of the cooperative's human resources through ongoing training related to tax regulations. In addition to having a direct impact on the efficiency of cooperative tax management, this program also provides contextual learning benefits for students in linking tax accounting theory with real conditions in the field.
