Abstract

This study examines the legal implications of Large Language Models (LLMs) within the Indonesian regulatory framework. As AI technologies rapidly evolve, Indonesia relies primarily on general laws on data protection, electronic systems, civil liability, and intellectual property to govern AI deployment. However, these laws were not specifically designed to address the autonomous and generative nature of LLMs. This research employs a normative legal methodology to analyze statutory provisions, identify regulatory gaps, and evaluate constitutional principles relevant to AI governance. The findings reveal fragmentation, ambiguity in training data legality, uncertainty in liability allocation, and limited transparency requirements. The study proposes a risk based and accountability-oriented governance framework that harmonizes existing sectoral regulations while strengthening human rights protection. By developing a coherent regulatory approach, Indonesia can enhance legal certainty, mitigate technological risks, and promote responsible innovation in the era of artificial intelligence.

Abstract

Agricultural systems face increasing challenges related to resource depletion, climate variability, and food insecurity, requiring innovative and sustainable solutions. This study examines the impact of intelligent agriculture on sustainability performance and food security outcomes. A quantitative comparative design was employed, involving several farms categorized into intelligent agriculture adopters and conventional farmers. Data were analyzed using a sliding time-window approach, Structural Equation Modeling (SEM), and predictive machine learning techniques to evaluate direct and mediated effects. The findings reveal that intelligent agriculture significantly improves yield (33% increase), reduces water and fertilizer use (approximately 25%), and decreases production variability by more than 50%. Sustainability performance strongly mediates the relationship between intelligent agriculture and food security, resulting in a 27% improvement in the Food Security Index. These results confirm that intelligent agriculture enhances long-term agricultural resilience and resource efficiency, providing empirical support for policies promoting digital farming technologies to achieve sustainable food systems.

Abstract

Early detection of melanoma is essential to reduce skin cancer related mortality. This study proposes a machine learning based framework for automatic classification of dermoscopic skin lesion images into melanoma and benign categories. The methodology integrates image preprocessing, deep convolutional feature extraction, and an attention mechanism to enhance clinically relevant patterns such as asymmetry, border irregularity, and color variation. The model was trained and evaluated using a labeled dermoscopy dataset with a structured train validation test split. Experimental results demonstrate strong diagnostic performance, achieving 92.8% accuracy, 94.1% sensitivity, 91.3% specificity, and an AUC of 0.96. The high sensitivity indicates effective identification of malignant cases, which is critical for early intervention. Overall, the proposed framework shows promising potential as a computer aided diagnostic tool to support dermatologists in improving consistency, efficiency, and reliability in melanoma detection.

Abstract

New student admission is an important administrative process in educational institutions that requires effective data management and information dissemination. At TKIT Al-Khattaby, the admission process was previously conducted conventionally through direct form completion, brochures, verbal communication, and WhatsApp. These practices caused delays in data processing, increased the risk of recording errors and data loss, and limited access to admission information for prospective parents or guardians. This study aims to develop a web-based New Student Admission Information System at TKIT Al-Khattaby to improve the efficiency and effectiveness of the admission process. The system was developed using the Waterfall methodology, comprising requirements analysis, system design, implementation, testing, and maintenance. The system was implemented using the Laravel framework and PHP programming language, with MySQL as the database management system. The developed system provides essential functionalities, including school information, online student registration, document uploading, applicant data management, registration verification, teacher and student management, news publication, and activity agenda management. System functionality was evaluated using Black Box Testing, which demonstrated that the main system functions operated according to the specified requirements. The developed system can improve the efficiency of new student admission management and facilitate broader access to admission-related information for prospective parents and the community.
