: 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 examines the presentation of trauma in the character of River in the film “The Architecture Of Love” through Roland Barthes' semiotic analysis, which includes three levels of meaning: denotative, connotative, and mythological. The focus of this study is on scenes that reflect trauma, categorized according to Cavanagh.M. (1982) theory as situational, developmental, intrapsychic, and existential trauma. The methodology used is descriptive-qualitative with documentation and observation techniques, where all trauma scenes are identified and analyzed in depth. The results of the study show that intrapsychic trauma is the dominant category, followed by existential, situational, and developmental trauma. The representation of trauma in the character River is conveyed through visual symbols such as dark colors, a closed language system, dim lighting, and a quiet urban atmosphere, which create emotional meaning without verbal expression. This finding confirms that films can convey complex psychological experiences through visually rich language, while also revealing new insights into non-verbal communication in film media.

Fifth grade students' consistently poor reading comprehension abilities, which impeded their overall academic development and participation in language acquisition, served as the driving force for this study. Using a comic assisted problem based learning (PBL) model, the study, which involved 39 students at SDN Purwamekar, aimed to improve learning activities in order to increase teacher and student participation and, eventually, improve fifth grade students' reading comprehension skills. By using comic strips to illustrate issues, this creative method made learning more engaging and accessible for younger students.

This study aims to examine in depth how gender equality values are integrated into Buddhist Religious Education (PAB) at the junior high school level, based on the Merdeka Curriculum. Through a content analysis approach to character representation, women's roles, language, visual illustrations, access to Dhamma education, gender equality values, role models of female characters, students' critical reflections, and narrative-visual consistency, this study identifies significant gaps in gender representation. Using a qualitative approach, data were collected through content analysis of PAB textbooks for grades VII–IX and interviews with three Dharma teachers in Jakarta. The results show that the representation of female characters in the textbooks is very limited and the learning narratives tend to be normative without addressing structural aspects of gender inequality. The findings indicate the dominance of male characters, the lack of functional narratives about nuns and women, and the use of language and illustrations that tend to reinforce traditional gender stereotypes. Although there are attempts to mention gender equality in some chapters, the integration is not comprehensive and consistent across the materials. This article recommends the development of a more inclusive curriculum and teaching materials, encouraging balanced gender representation, and integrating gender equality values holistically in Buddhist religious education to form a more equitable and comprehensive understanding for students, as well as teacher training based on critical pedagogy and revision of learning content to reflect gender equality in Buddhist teachings.

MP3 audio files are often used in a variety of fields, but they are prone to security risks such as eavesdropping and illegal access. This study proposes a super encryption method by combining the algorithms of Rivest Shamir Adleman (RSA) and ElGamal to improve the protection of audio data. RSA was chosen for its efficiency and ease of implementation, while ElGamal offers a high level of security through discrete logarithmic complexity. The combination of the two is expected to address the weaknesses of each algorithm and strengthen file security. The system is developed using the Python programming language with the Visual Studio Code environment. The encryption process is done in layers: MP3 files are first encrypted with RSA, and then the results are encrypted again with ElGamal. The decryption is done in reverse order. Tests are conducted with various MP3 file sizes to measure the effectiveness and performance of the system. The results show that this method is able to secure audio files so that they cannot be accessed without the private keys of both algorithms. Although processing times are increased compared to single encryption, the level of security obtained is much higher. This approach can be an effective solution for protecting digital audio data, particularly MP3 format, and could potentially be applied to a wide range of other data types that require a high level of security.
