Abstract

Historical awareness is critical for students because it fosters a deeper understanding of the past, strengthens their ability to see connections between historical events, and supports the development of national identity. Effective teaching materials are needed to increase this awareness. This research aims to develop and evaluate e-comic teaching materials designed to increase students' historical awareness. Research and Development (RD) includes four stages: defining (data collection), designing (creating teaching materials), developing (expert testing), and disseminating (application of validated teaching materials). The research subjects consisted of 6 validity experts, 2 teachers, 30 and 90 grade XII students to assess the pragmatism and effectiveness of the teaching materials developed. Data collection was carried out through validity and practicality questionnaires, observations, interviews, and student assessment sheets. The validity and practicality of teaching materials are analyzed qualitatively, while their effectiveness is measured quantitatively with the T and N-Gain tests. The research results show that e-comic teaching materials have a validity score of 4.02, which indicates strong validity in increasing students' historical awareness. A practicality score of 4.07 indicates ease of use, making it easier for students to access the material. The T-test with a significance of 0.001 shows a significant effect of e-comics, while the N-Gain test shows an increase in students' historical awareness by 66%, indicating the effectiveness of this intervention in achieving learning objectives. The use of e-comics teaching materials in the classroom has proven to be feasible, practical, and useful for increasing students' historical awareness, thus contributing significantly to history education.

Abstract

The increasing adoption of AI in critical sectors such as healthcare, finance, transportation, and public services raises significant challenges related to transparency, accountability, and trust in automated decision-making processes, particularly since many AI models still operate as black boxes that are difficult to interpret and audit. This study investigates the potential of integrating blockchain technology to enable trustworthy and transparent AI decision-making and is conducted under the framework to systematically design, implement, and evaluate the proposed solution. The proposed framework records AI inference results and relevant metadata onto the blockchain through smart contracts to ensure data immutability and traceability. A prototype system is developed and evaluated using a mixed-method approach, combining qualitative analysis of transparency and auditability with quantitative measurements of system performance such as latency and overhead. The results demonstrate that blockchain integration significantly enhances auditability, data integrity, and user trust compared to conventional AI systems. However, several limitations are identified, including scalability issues, transaction costs, and increased latency caused by on-chain recording processes. Despite these challenges, the proposed approach shows strong potential to improve the accountability of AI systems in high-risk environments and contributes a practical framework along with empirical insights for organizations seeking to adopt transparent and reliable AI, while also opening opportunities for further development through architectural optimization and the adoption of layer-2 blockchain technologies.
