Abstract

This study addresses gaps in vocational trigonometry learning by integrating ethnomathematics and Tri-N pedagogy into an Android-based module to enhance mathematical literacy and engagement. Research and Development (R&D) with a 4D model (Define, Design, Develop, Disseminate) was applied. Data were collected from expert validation sheets and student response questionnaires, and analyzed using descriptive and quantitative methods. The module achieved high validity (87.77%) and strong student acceptance (83.55%), indicating practicality and suitability for classroom use. The integration of Tri-N stages with ethnomathematical contexts and mobile technology supports active learning and cultural relevance, contributing theoretically to contextual mathematics education and practically to digital learning innovations. The developed module is valid and practical for vocational trigonometry instruction. Future research should explore scalability and effectiveness through broader trials.

Abstract

This research aims to identify and mitigate security vulnerabilities in the Hospital Information System (SIMRS) using the OWASP Web Security Testing Guide (WSTG) v4.2 based testing method. With the help of the OWASP ZAP tool, various vulnerabilities were identified, such as SQL Injection, weaknesses in session management, lack of security attributes in cookies, and disclosure of sensitive information through URLs or code comments. SQL Injection was identified as the highest risk vulnerability, as it potentially allows attackers to access, manipulate, or delete sensitive data in the database. In addition, weaknesses in cookie attributes, such as HttpOnly and SameSite, and the absence of an anti-CSRF mechanism, indicate potential threats in the form of Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF). The implementation of a solution based on WSTG v4.2 involves steps such as the implementation of HTTPS encryption, the use of prepared statements for database interaction, the application of security headers such as Content-Security-Policy (CSP), and input validation to reduce the risk of XSS. In addition, code audits were conducted to remove sensitive comments, while hidden files or unnecessary backups were removed to minimize the potential for information leakage. Test results after the implementation of the solution showed a significant improvement in the security level of the application. This research proves that the WSTG v4.2-based approach can provide comprehensive and systematic guidance in web application security testing. With these results, organizations, particularly in the healthcare sector, can ensure better protection of patient data and comply with applicable information security standards.

Abstract

This study benchmarks YOLO26 against YOLOv11 for detecting minority waste categories (Hazardous/B3 and Residue), evaluating whether YOLO26's Progressive Loss Balancing (ProgLoss) and Small-Target-Aware Label Assignment (STAL) mechanisms address class imbalance and small-object detection challenges. Both models were trained under identical conditions (50 epochs, 640×640) on a combined TACO, RecyBat24, and Food Waste Detection dataset (2,326 images, 70:15:15 split), across three scenarios: YOLOv11 baseline, YOLO26 default, and YOLO26 with class weighting and copy-paste augmentation. YOLO26 (default) achieved a marginally higher mAP@0.5:0.95 (0.393 vs 0.385) and modestly faster CPU inference (≈20% faster) than YOLOv11, with near-identical mAP@0.5 across scenarios. B3 performed consistently well (mAP@0.5 ≈ 0.99), and class weighting improved its detection robustness without raising overall mAP. Residue detection remained the weakest across all scenarios (mAP@0.5 0.076–0.085) and worsened under weighting, indicating that ProgLoss and STAL alone do not resolve its structural visual heterogeneity; this weak, stable Residue performance was confirmed reproducible across three additional training runs with different seeds (mAP@0.5:0.95 = 0.046 ± 0.001). These findings partially support the research hypothesis, positioning YOLO26 (default) as a favorable accuracy-efficiency trade-off for automated waste sorting, while Residue detection requires further data enrichment and augmentation strategies beyond architectural improvements alone.

Abstract

The increasing use of digital learning resources has created a growing demand for secure ebook distribution systems. However, many existing ebook platforms remain vulnerable to unauthorized access, credential sharing, and uncontrolled digital content distribution. This study proposes an Authentication-Based Access Control Framework for secure web-based ebook distribution by integrating authentication, role-based authorization, session management, transaction validation, and ebook access protection within a unified security architecture.The research employed the Waterfall software development model consisting of requirement analysis, system design, implementation, testing, and deployment. The proposed framework was implemented using PHP and MySQL and evaluated through functional and security testing.The implementation results demonstrate that the developed system successfully manages 153 registered users, 151 ebook transactions, and six published ebook collections while maintaining controlled access to digital content. Functional testing achieved a 100% success rate across authentication, authorization, session validation, and ebook protection scenarios. The session management mechanism effectively prevented concurrent account usage and unauthorized access attempts.The novelty of this study lies in the integration of authentication, authorization, session validation, and ebook access protection within a dedicated framework specifically designed for ebook distribution. The proposed framework provides a practical, scalable, and cost-effective alternative for educational institutions and digital content providers seeking secure digital resource distribution without relying on complex Digital Rights Management (DRM) infrastructures.
