Abstract

Technological developments encourage digitization in the learning process. Inversely proportional to the results of competency evaluation which are still centralized. Cause competitiveness and competence of students that are not measured quantitatively. The application of micro-teaching can be an option in solving existing problems. Combining gamification and blockchain makes the learning process more enjoyable with game techniques, where activities such as learning, lecture assignments, and assessments are documented transparently and have reliable security. This student-centered learning process is called GamiChain (Gamification Blockchain). This blockchain gamification-based learning application is also an important activity that can be a brilliant breakthrough in education. This application aims to encourage the student creativity ecosystem, to make students have a more competitive spirit to compete with maximum capabilities. And can display learning outcomes in the form of certificates that are accurate in authenticity and can be used in the industrial world. GamiChain can form an official standard of learning by documenting lectures permanently, transparently, and distributed formally and informally into the Blockchain network with the help of smart contracts. The Gamification method in education is used in this research. Results Evaluation of blockchain application in education through GamiChain (Gamification Blockchain) can benefit universities to create official certifications and increase confidence in student scores transparently and sustainably that they can control.

Abstract

The rapid adoption of face recognition technology for attendance systems has raised concerns about its reliability under varying lighting conditions, which often affect real world deployment. This study aims to analyze the reliability of a face recognition based attendance system under diverse lighting scenarios, addressing challenges in accuracy and robustness. The research employs a deep learning approach, utilizing a Convolutional Neural Network (CNN) trained on a dataset of facial images captured under controlled and uncontrolled lighting conditions, ranging from low to high illumination levels. The methodology includes preprocessing techniques for illumination normalization and feature extraction, followed by performance evaluation using metrics such as accuracy, precision, and false acceptance rate. Experimental results demonstrate that the proposed system achieves an accuracy of 92% in optimal lighting but drops to 78% under low light conditions, highlighting the impact of illumination on recognition performance. The integration of adaptive preprocessing techniques improves reliability by 12% in challenging scenarios. This study concludes that while face recognition based attendance systems are highly effective, their reliability in diverse lighting conditions can be significantly enhanced through advanced preprocessing and robust algorithm design, offering practical implications for real time biometric applications in dynamic educational and workplace settings.

Abstract

In the fashion industry, particularly within the anime clothing brand sector, building consumer loyalty has become a crucial challenge for ensuring long- term growth while supporting sustainability principles aligned with the Sustainable Development Goals (SDGs), specifically SDGs 8 and SDGs 12. This study aims to analyze various digital marketing approaches that can enhance consumer loyalty toward anime clothing brands by examining how digital interactions, visual identity, and community engagement contribute to sustained brand consumer relationships. The research employs a descriptive qualitative approach supported by observational data from social media analytics, documentation of digital campaign activities, and the interpretation of consumer engagement patterns across multiple digital platforms. The findings indicate that digital strategies such as leveraging social media to strengthen brand presence, collaborating with anime influencers, utilizing community based content, and implementing personalization through email marketing and loyalty programs effectively increase consumer emotional attachment and behavioral loyalty. Brands that successfully create emotionally engaging digital experiences and interact authentically with their audiences demonstrate a stronger potential to build sustainable loyalty. Furthermore, maintaining consistent brand com- munication, ensuring continuity in marketing campaigns, and integrating SDGs oriented values are identified as essential components for sustaining long-term relationships with consumers. The study concludes that digital marketing not only strengthens brand visibility but also plays a strategic role in shaping responsible consumer behavior, fostering loyalty within niche fashion communities, and supporting broader sustainability goals in the anime fashion industry.
