This study aims to describe the implementation of discipline values and the obstacles faced at MI Darul Hikmah Agung Jaya. Using a descriptive qualitative approach, data were collected from teachers, students, and parents through interviews, observations, and documentation, then analyzed through data reduction, display, and conclusion drawing. Data validity was ensured by triangulation of techniques and sources. The findings show that teachers instill discipline values through two main techniques. First, external control, in which teachers give warnings, threats, or punishment to undisciplined students and provide rewards or praise to those who obey the rules. For example, students who consistently complete homework may receive additional grades or verbal appreciation. Second, teachers also become role models, demonstrating punctuality, neat appearance, polite language, and respectful attitudes, thereby fostering discipline by example. Furthermore, teachers apply cooperative control, emphasizing collaboration and agreements between teachers and students. This approach promotes tolerance, respect, and responsibility by involving students in creating and maintaining classroom rules. However, some obstacles were identified. Teachers were sometimes less assertive in enforcing discipline, and limited variation in teaching methods led to student boredom. In addition, inadequate attention, motivation, and parental support negatively influenced students’ discipline, resulting in lateness, incomplete assignments, and other undisciplined behaviors.

Teachers are required to adopt a wise and thoughtful approach in teaching, since their perception of students will influence their attitudes and actions. Not all teachers assess students in the same way, and this affects the methods they apply in the classroom. To achieve optimal learning outcomes, teachers must take on new roles as facilitators, mediators, learning partners, and evaluators. This means creating a democratic and dialogical learning atmosphere between teachers and students, as well as among students themselves. One effective way is by applying the PAIKEM learning model (Active, Innovative, Creative, Effective, and Enjoyable). This study aims to: (1) Describe the implementation of the PAIKEM model in Islamic Religious Education for Grade VII at Darul Ishlah Junior High School. (2) Describe the obstacles encountered in applying this model. The research uses a qualitative approach with interviews, observation, and documentation as data collection techniques. Data analysis was conducted through reduction, presentation, and conclusion drawing. The results indicate that the PAIKEM model has been implemented well, through discussions, opportunities for students to express opinions, group assignments, interactive communication, motivation, use of media such as videos, and enjoyable memorization. However, challenges include limited learning media, teachers’ creativity that is not yet optimal, inadequate facilities and infrastructure, and low student motivation.

This systematic literature review examines the philosophy of science approaches to user security in distributed devices, such as IoT and Federated Learning. The review was conducted in response to the exponential growth of connected devices and the increasing security threats, including cyberattacks, data breaches, and unauthorized access. As distributed systems become more complex, traditional security approaches, such as cryptography and differential privacy, are often insufficient to address the ethical, philosophical, and contextual challenges that arise in these ecosystems. Distributed devices, especially in IoT and Federated Learning contexts, rely on vast amounts of personal data. This data, often stored or processed in decentralized environments, creates significant risks to user privacy and system integrity. As the number of connected devices grows, security risks multiply, creating challenges in maintaining user trust, privacy, and overall system resilience. Conventional techniques, such as encryption, only focus on technical aspects, often neglecting the deeper philosophical dimensions, such as the nature of knowledge, privacy, and fairness in these systems. These gaps highlight the need for a more nuanced approach that incorporates philosophical perspectives into security frameworks. This study uses a systematic literature review method based on the PICOC (Population, Intervention, Comparison, Outcome, Context) framework to analyze the relevance of epistemology, ontology, and ethics in strengthening system security. By examining the foundational principles of how knowledge is constructed (epistemology), what entities exist in the system (ontology), and the ethical considerations around data and user privacy (ethics), the review provides a comprehensive understanding of how philosophical concepts can be integrated into the design and implementation of security systems in distributed environments. The results reveal that epistemological principles, such as the verification and validation of data sources and models, can significantly improve the reliability and trustworthiness of distributed systems.  

This study aims to examine in depth the role of Islamic Religious Education (PAI) in shaping the character and ethics of students at Madrasah Aliyah Al-Hikmah, Ciruas, Serang, Banten. Amidst the challenges of globalization and modernization that bring changes in values and behavior, PAI plays a strategic role in instilling moral, spiritual, and social values in students. Religious education not only teaches religious knowledge but also shapes attitudes, behaviors, and mindsets in accordance with Islamic teachings, enabling students to cope with diverse environmental influences. This study uses a qualitative descriptive approach with data collection techniques through observation, in-depth interviews, and documentation studies. Research informants consisted of PAI teachers, students, the principal, and homeroom teachers, thus obtaining a comprehensive picture of the implementation of PAI at the madrasah. The results show that PAI makes a significant contribution to the formation of student character, particularly in aspects of religiosity, discipline, responsibility, honesty, tolerance, and courtesy. Learning strategies used include habituating worship, teacher role models, enforcing school rules, and integrating Islamic values into all subjects. Additionally, extracurricular activities such as religious study groups, Islamic holiday commemorations, and Quran memorization programs are also effective tools for strengthening students' character. However, this study also identified several challenges, including low parental involvement in children's character development, negative environmental influences, and limited variety of learning methods. Therefore, synergy between madrasahs, families, and the community is needed to create an educational ecosystem that supports comprehensive and sustainable character development. Through this collaboration, Islamic Religious Education (PAI) is expected to provide a strong foundation for creating a generation with noble character and competitiveness in the modern era.

Assessment practices in Indonesian schools remain largely dominated by conventional summative evaluation, which inadequately represents reflective learning processes and mastery of 21st-century competencies. This gap highlights the suboptimal implementation of formative and authentic assessments in educational practice, as well as the lack of conceptual models capable of systematically integrating both approaches. This article aims to examine and develop an integrative assessment model that combines three key approaches: formative assessment, authentic assessment, and Evidence-Centered Design (ECD), as a strategic framework to strengthen assessment practices for 21st-century learning. This study is based on a conceptual synthesis of more than 20 national and international sources. A narrative review approach is employed, focusing on the three main approaches: formative assessment, authentic assessment, and ECD. The results of the review produce an integrative assessment model articulated in the Claim–Task–Evidence–Feedback syntax, which merges competency mapping (claim), real-world task design (task), student performance evidence collection (evidence), and continuous formative feedback (feedback). This model not only unifies the strengths of the three approaches but also offers practical solutions to the challenges of assessment implementation in Indonesia through practice-based training, integration into instructional planning, and support from technical policy frameworks. The article contributes to the advancement of assessment design that is pedagogically valid, contextually relevant, and instrumental in driving learning transformation.

This study investigates the effectiveness of an integrative learning model in improving Indonesian literature appreciation skills among high school students. A quasi-experimental design was employed, involving 120 eleventh-grade students from two public high schools in Jakarta, Indonesia. The participants were divided into two groups: the experimental group, which received instruction through the integrative learning model, and the control group, which followed traditional teaching methods. The integrative model was designed to combine language skills development—such as reading comprehension, vocabulary enrichment, and critical writing—with structured literary analysis focusing on themes, characterization, style, and cultural context. Data were collected using pre-test and post-test assessments to measure learning outcomes, observation sheets to monitor classroom activities, and student questionnaires to capture perceptions and engagement levels. The results indicated that students in the experimental group experienced a significantly higher improvement in literature appreciation skills compared to those in the control group (p < 0.05). They demonstrated enhanced abilities to interpret literary works, analyze narrative elements, and articulate critical responses to Indonesian contemporary literature. Observation data revealed that the integrative approach fostered more active participation, collaborative learning, and deeper reflection during classroom discussions. Moreover, student feedback highlighted increased motivation, enjoyment, and perceived relevance of literature learning to real-life experiences. These findings underscore the pedagogical potential of integrative learning models in secondary school literature education. By linking language proficiency with analytical and interpretative competencies, this approach not only strengthens students’ linguistic abilities but also cultivates their critical thinking, cultural awareness, and aesthetic appreciation. The study recommends the wider adoption of integrative methods in Indonesian high schools as an effective strategy for promoting meaningful and enduring engagement with literature.

Delivery delays pose a major challenge in the e-commerce industry, often leading to decreased customer satisfaction and negatively impacting business operations. In this study, the XGBoost (Extreme Gradient Boosting) algorithm is applied to predict delivery delays based on a dataset containing 96,476 records. These records include various features relevant to the delivery process, such as shipping distance, carrier performance, and order characteristics. The model achieves a high overall accuracy of 93.24%, indicating strong general performance. In particular, XGBoost demonstrates excellent results in predicting on-time deliveries, achieving a precision of 93% and a recall of 100%. However, the model struggles to correctly identify delayed deliveries. The recall for delayed deliveries is 0%, and the F1-score is extremely low at 0.01. This significant discrepancy reveals a critical limitation in the model's performance — the inability to detect minority class cases (delayed deliveries) due to class imbalance within the dataset. The results highlight the importance of addressing data imbalance in predictive modeling for delivery outcomes. When the dataset is dominated by on-time delivery records, the model tends to be biased toward that class, failing to learn the patterns associated with delays. To improve performance, the study recommends integrating class balancing techniques such as SMOTE (Synthetic Minority Oversampling Technique) to generate synthetic samples of the minority class. Additionally, the use of alternative evaluation metrics beyond accuracy — such as precision, recall, and F1-score for each class — is suggested to provide a more comprehensive understanding of model effectiveness. Overall, the study provides valuable insights into the complexities of predicting delivery delays and outlines practical strategies for enhancing future models in e-commerce logistics analytics.
