Abstract

Magnetic Resonance Imaging (MRI) plays a vital role in the early detection of brain tumors. However, standard Convolutional Neural Network (CNN) models often struggle to extract truly relevant features from complex MRI structures. This limitation creates a gap in achieving robust and clinically interpretable classifications, as feature redundancy and weak attention toward tumor-specific regions may reduce diagnostic reliability. To address this gap, this study introduces a Neural Dynamic Network (NDN) that integrates EfficientNetV2S with a dynamic attention-based mechanism to adaptively highlight informative features while suppressing noise. The proposed model was evaluated using a 5-fold cross-validation scheme and tested on unseen data. Compared with the baseline CNN, the NDN consistently demonstrated higher accuracy, precision, recall, and F1-score across folds and final testing, reflecting improved robustness and balanced sensitivity. NDN yielded significant improvements, with the 5-fold validation averaging an accuracy of 88.44%, a precision of 87.84%, a recall of 87.88%, and an F1-score of 87.82%.  Beyond numerical performance, interpretability analysis utilizing Grad-CAM demonstrated that NDN generates more concentrated and clinically consistent heatmaps. In contrast, the baseline CNN produced dispersed activations that exhibited less alignment with tumor regions. Overall, the findings confirm that incorporating a dynamic attention-based mechanism substantially enhances both feature selection and visual interpretability. This makes the NDN architecture more reliable for MRI-based brain tumor classification and highly suitable as a decision-support tool in clinical workflows.

Abstract

This study aims to analyze the legality of blockchain-based digital evidence in criminal justice processes in Indonesia, emphasizing two main focuses: the possibility of its admissibility as valid evidence and the identification of accompanying normative, technical, and procedural limitations. This study uses a normative juridical method through a legislative approach (the ITE Law, the Personal Data Protection Law, the Criminal Procedure Code, and Supreme Court Regulations), a conceptual approach (the concept of digital evidence, blockchain technology, and audit trails), a comparative approach (comparison of practices in several other jurisdictions), and a case approach through analysis of court decisions relating to electronic evidence. The results show that blockchain technology has significant potential to be recognized as evidence with strong probative value due to its characteristics of immutability, transparency, and traceability. However, this study also identifies several challenges, including the lack of specific regulations in the Criminal Procedure Code, potential conflicts with the principle of personal data protection, the absence of uniform digital audit trail standards, the heterogeneity of blockchain systems, and the limited technical capacity of law enforcement officials. These findings underscore the urgency of regulatory reform, standardization of evidentiary procedures, and strengthening the technical competence of law enforcement officials so that blockchain-based evidence can be implemented effectively and accountably in criminal proceedings. Practically, the results of this study provide a basis for policymakers to formulate a legal framework and technical policies that adapt to the use of blockchain technology in the criminal evidence system without neglecting the principles of human rights protection and legal certainty. Overall, this study contributes conceptually and normatively to the integration of blockchain technology into the Indonesian criminal justice system.

Abstract

Background: The rapid expansion of the global digital economy has intensified the importance of regulating data governance, particularly in relation to digital sovereignty and the protection of personal data. However, significant differences persist among national legal frameworks, creating regulatory gaps in cross-border data governance and oversight mechanisms. This condition raises critical legal and policy challenges, especially for developing countries such as Indonesia. Objective: This study aims to analyze and compare the principles of digital sovereignty and the right to personal data in Indonesia, the European Union, and the United States, as well as to assess their legal implications for national policy formulation in each jurisdiction. Methods: This research employs a descriptive qualitative approach using a comparative juridical method. A statutory approach is applied to examine relevant laws and regulations, a comparative approach is used to analyze differences in data governance frameworks across jurisdictions, and a conceptual approach is employed to explore theoretical perspectives on digital sovereignty and data rights. Results: The findings indicate that Indonesia emphasizes state control over data and the obligations of electronic system operators, the European Union prioritizes comprehensive protection of data subjects’ rights through the General Data Protection Regulation, while the United States adopts flexible, sectoral regulations oriented toward private sector innovation. These differing paradigms result in variations in oversight effectiveness, levels of data protection, and cross-border data transfer mechanisms. Conclusion: This study highlights the urgency for Indonesia to strengthen regulatory harmonization, enhance institutional oversight capacity, and develop equitable cross-border data transfer mechanisms in order to reinforce digital sovereignty while aligning with international data protection standards.
