Abstract

As a country based on legal principles, Indonesia has a responsibility to respect and prioritize the principles of the rule of law, including independence and the absence of partiality in the judicial system. The level of success in implementing this principle can be measured by the extent to which the judiciary is independent in carrying it out to realize justice based on the law. However, the power of the Constitutional Court (MK) cannot be avoided from criticism and evaluation. For example, a Constitutional Court decision attracted public attention regarding the requirements for presidential and vice presidential candidates. Therefore, this article discusses the impact of the controversy that emerged after the decision of the Constitutional Court (MK) in Case Number 90/PUU-XXI/2023 on January 4 2023. This decision, which includes the cancellation of part of Law Number 7 of 2017, has raised various criticisms and doubts about the independence of the Constitutional Court. By focusing on the role of Chief Justice of the Constitutional Court Anwar Usman in minority opinions, this article analyzes the examination carried out by the Honorary Council of Constitutional Court Judges (MKMK) regarding alleged ethical violations. The implications for the credibility of the Constitutional Court as a democratic oversight institution are a major concern in this context.

Abstract

This study aims to analyze the legal status of illegitimate children from the perspective of Islamic law and civil law in Indonesia, focusing on aspects of lineage, inheritance rights, and legal protection. This study uses a literature study method with descriptive-analytical analysis to compare regulations in Islamic law and positive law. In Islamic law, illegitimate children only have lineage and inheritance rights through the mother and her family, while in civil law, illegitimate children can obtain legal recognition from their parents through a process of recognition or a court decision. This study also highlights the role of the Constitutional Court Decision Number 46/PUU-VIII/2010 which provides further legal protection for illegitimate children, especially regarding civil rights. Although there are fundamental differences in the recognition of lineage and inheritance rights, both legal systems agree on the importance of protecting children's basic rights

Abstract

Adolescents in Tasikalaya District show a tendency to be susceptible to Tramadol protection, a type of opioid analgesic commonly used to reduce moderate to severe pain. This phenomenon is a resource for the medical community, health practitioners, local governments and other related parties. Serious attention is needed to this problem to prevent negative impacts on the health and welfare of adolescents in the region. Coordinative efforts between the health, education and government sectors need to be strengthened to develop effective prevention and intervention strategies. A deep understanding of the factors driving Tramadol is key in designing appropriate preventive measures. This research examines the use of the drug tramadol among teenagers in Tasikalaya Regency using a qualitative approach and Differential Association Theory. The results of the study showed that adolescents' support for tramadol was caused by social and environmental factors, including interactions with peers and family members who also used the drug. Teenagers often rationalize their behavior and have certain attitudes that influence their decision to take tramadol. Apart from that, the easy availability of tramadol medication and affordable prices also influences teenagers' choices. This study provides a deeper understanding of the problem of tramadol among adolescents and suggests comprehensive preventive measures.

Abstract

Early detection of Down Syndrome in children is crucial to provide more appropriate medical and educational interventions. This study aims to build and evaluate a deep learning-based classification model using the EfficientNetB0 architecture to distinguish facial images of children with Down Syndrome and healthy children. The dataset used consists of two classes (Down Syndrome and healthy), which have gone through an augmentation process to increase data diversity and prevent overfitting. The model was trained using the Adam algorithm with a learning rate of 0.0001 and a sparse categorical crossentropy loss function for 10 epochs. The training results showed that the model achieved a validation accuracy of 93.94%, with the lowest validation loss value of 0.2390. Further evaluation was carried out using a confusion matrix, which showed that the model was able to properly classify 312 out of 333 Down Syndrome images and 309 out of 330 healthy children images, resulting in an overall accuracy of 94%. In addition, the precision, recall, and f1-score values ​​for both classes were in the range of 0.94, indicating a balanced and strong performance. Visual analysis of the misclassified images indicates that some misclassifications occur on healthy children’s faces with certain expressions, angles, or lighting conditions that resemble Down syndrome. Conversely, some children with Down syndrome are also predicted as healthy when their facial features are not too prominent or similar to normal children under certain lighting conditions. This shows that despite the high performance of the model, sensitivity to facial feature variations remains a challenge.

Abstract

The development of artificial intelligence (AI) in the last two decades has significantly changed the face of democratic politics. AI is used in political campaigns, policy-making, and interactions between governments and citizens. For example, the launch of an AI tool called Nostrada in the UK that allows the public to interact with digital avatars of members of parliament, and the use of AI in the 2024 US election campaign to personalize messages and raise funds. However, the use of AI also poses major risks, such as the spread of disinformation through deepfakes and social media bots, and the amplification of algorithmic bias that can harm certain groups. AI systems that operate as “black boxes” pose challenges to transparency and accountability in political decision-making, thereby reducing public trust. Several countries, especially the European Union, have begun to implement regulations to prevent the misuse of AI, such as transparency obligations and deepfake detection. In addition to regulations, digital literacy is key to strengthening critical public participation in digital content. This study uses a qualitative-descriptive approach with a literature review to analyze the benefits and risks of AI in politics. The results emphasize the need for cross-sector collaboration to develop ethical and transparent policies so that AI strengthens digital democracy, not weakens it. This study highlights the importance of balancing technological innovation and protecting democratic values ​​in the face of an increasingly complex digital era.

Abstract

This study examines the transformation of language form and function in digital communication, focusing on platforms such as Twitter, TikTok, Instagram, Reddit, and Kaskus. Through a qualitative-descriptive approach and multimodal analysis of 2,000 digital entries, it was found that digital communication forms a new language genre that is hybrid, visual, and performative. Phenomena such as code-mixing, acronyms, phonetic spelling, and the use of emoticons and memes reflect linguistic adaptations to the speed, efficiency, and emotional expression that characterize digital platforms. The findings show linguistic variation between generations: Gen Z tends to use visual symbols and concise language, while older generations (Millennials and Gen X) maintain a more formal sentence structure. Data visualization using NVivo and Voyant Tools strengthens the identification of dominant themes such as emotion, irony, and community slang. These findings support previous literature, such as Barrot (2022) and Kurmanbekova et al. (2023), which highlight the simplification and diversification of language in the digital era. This study confirms that social media is not only a space for linguistic expression, but also an arena for innovation, the spread of digital dialects, and shifts in communication norms. While bringing creativity and cultural engagement, these changes also raise concerns about the decline in formal literacy skills. Therefore, this study recommends further exploration of the long-term impact of digital language use on literacy education and culture.

Abstract

The rapid advancement of information technology and digitalization has significantly transformed the financial sector, particularly with the emergence of cryptocurrencies characterized by high price volatility and complex movement patterns. Accurate price prediction of these crypto assets is essential to support investment decision-making and risk management. This study aims to compare the performance of six activation functions ReLU, Tanh, Sigmoid, Softplus, Swish, and Mish in a Simple Recurrent Neural Network (RNN) model for predicting the price of Litecoin, a widely traded cryptocurrency. Using historical daily closing price data from May 2020 to April 2025, the data were preprocessed through Min-Max normalization and sliding window sequence formation to fit the RNN input requirements. Each activation function was applied in the RNN model under consistent training conditions, and model performance was evaluated using Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and coefficient of determination (R²). Results indicate that the Swish activation function outperforms others by achieving the lowest RMSE of 4.58 and the highest R² score of 0.9578, demonstrating superior prediction accuracy and stable convergence. Tanh also showed competitive results, while Sigmoid and Softplus performed less effectively. In conclusion, Swish is recommended as the most suitable activation function for RNN-based cryptocurrency price forecasting due to its balance of accuracy and computational efficiency.
