: The rapid expansion of cybersecurity standards and threat intelligence frameworks has led to significant semantic fragmentation among security terminologies, hindering effective information retrieval and interoperability across systems. Traditional keyword-based search approaches are inadequate for capturing the contextual meaning of security terms, particularly within formal frameworks such as NIST, MITRE ATT&CK, and CWE. This study addresses this challenge by proposing CyberBERT, a transformer-based semantic search framework designed to align cybersecurity terminologies through deep contextual representation and ontology-driven reasoning. Research Objectives: The primary objective of this research is to develop a semantic retrieval model capable of understanding conceptual relationships between security terms beyond lexical similarity. Methodology: The proposed methodology fine-tunes a BERT-based model on the NIST Glossary corpus using a combination of masked language modeling and triplet loss objectives to generate discriminative semantic embeddings. These embeddings are further aligned with cybersecurity ontologies, including MITRE ATT&CK and CWE, to enhance semantic consistency and explainability. Semantic retrieval is performed using cosine similarity within a 768-dimensional embedding space and evaluated using Mean Reciprocal Rank (MRR) and Precision@K metrics. Results: Experimental results demonstrate that CyberBERT achieves an MRR of 0.832, outperforming domain-adapted baselines such as SecureBERT and CyBERT. The integration of ontology alignment improves semantic accuracy by over 6%, while robustness evaluations confirm resilience against adversarial linguistic perturbations. Visualization using t-SNE reveals coherent semantic clustering aligned with the five core NIST Cybersecurity Framework functions. Conclusions: In conclusion, CyberBERT effectively bridges semantic gaps across cybersecurity terminologies by combining transformer-based contextual learning with ontological reasoning. The framework offers a robust, interpretable, and scalable solution for semantic search, supporting improved interoperability and knowledge discovery in cybersecurity operations and standards harmonization.

This study aims to analyze the improvement of students’ knowledge and the alignment of the Civic Education learning model with the characteristics of third-grade students at SDN Kadipiro. The research problem arises from the tendency of Civic Education in elementary schools to rely heavily on lecture-based instruction, which results in low student engagement and limited comprehension of abstract concepts such as rights and obligations. A descriptive qualitative approach was employed through observations, interviews, and documentation to obtain a comprehensive picture of the learning process, the instructional model applied, and classroom dynamics. The findings reveal that the teacher implemented a game-based Discovery Learning model that emphasizes exploration, categorization, verification, and independent conclusion-making by students. This model proved effective, as evidenced by 85% of students being able to understand and distinguish examples of rights and obligations in accordance with the Civic Education learning outcomes. The study also indicates that game-based learning is more compatible with the students’ predominant visual and kinesthetic learning tendencies, enabling them to maintain focus more effectively than when using traditional lecture methods. However, several challenges emerged, including variations in students’ writing literacy skills and the absence of a structured assessment rubric. These findings underscore the need for flexible instructional design, the integration of concrete learning media, and the implementation of more systematic formative assessment practices. Future research is recommended to develop differentiated instructional strategies and to utilize more diverse media to accommodate the needs of heterogeneous classrooms.

Education is a strategic effort to overcome ignorance and poverty, which remain serious problems in Indonesia. Through education, individuals can acquire knowledge, skills, and a broad understanding of the world, thereby improving their quality of life and contributing to the nation's progress. Quality education will create superior, independent, and competitive human resources in the era of globalization. In this article, the author attempts to examine issues related to the implementation of education in schools through a qualitative approach. The research was conducted using several methods, namely observation, interviews, and field notes. Observations were conducted directly in the school environment to thoroughly understand the context being studied, including interactions between school members and the implementation of the learning process. Furthermore, interviews were used to gather information from informants, such as teachers, students, and school staff, to gain a deeper insight into the realities of education on the ground. Meanwhile, field notes were used as a tool for documentation and reflection on the results of the observations and interviews, which later became the basis for knowledge discovery and theory strengthening. The simultaneous use of these three methods enabled the author to obtain rich and in-depth data. This research shows that in the implementation of education still face several obstacles, such as limited facilities, lack of training for educators, and suboptimal parental involvement. Therefore, the implementation of education must be carried out through careful planning, appropriate strategies, and collaboration between various parties in order to achieve educational goals effectively and sustainably.  

This research aims to improve the learning outcomes of Natural and Social Sciences (IPAS) by applying a discovery learning model assisted by image media in grade V of SD Nurul Khoir, Jambi City. The method used is Class Action Research (PTK) which is carried out in two cycles. Each cycle consists of four stages, namely planning, implementation of actions, observation, and reflection. The research subjects amounted to 26 students. Data collection techniques are carried out through learning outcome tests, observation of teacher and student activities, and documentation. The results of the study showed a significant increase in the completeness of student learning outcomes. In cycle I, completeness reached 73.92%, and increased to 85.30% in cycle II. This improvement shows that the application of the discovery learning model combined with image media is effective in improving IPAS learning outcomes. This model encourages active involvement of students in the learning process, fosters curiosity, and hones critical and logical thinking skills. Image media as a visual aid has also been proven to be able to strengthen concept understanding and improve students' memory of the material studied. In addition, the learning process becomes more fun and meaningful because students are directly involved in the activity of discovering concepts through the stages of observing, questioning, gathering information, reasoning, and concluding. Teachers are no longer the center of information, but play the role of learning facilitators. This strategy is also relevant to the cognitive development characteristics of elementary school students who tend to favor concrete and visual learning. Thus, the application of the discovery learning model assisted by image media can be an alternative to an effective and innovative learning strategy in improving social studies learning outcomes. Teachers are advised to continue to develop adaptive, creative, and contextual learning methods and media.
