Abstract

Background. The integrity and equity of assessment in hybrid learning environments have been increasingly challenged by issues of transparency, bias, and centralized control. Traditional peer review systems often lack traceability and accountability, leading to concerns about the fairness and credibility of formative feedback. Purpose. This study explores the application of blockchain technology as a decentralized infrastructure for peer review and e-assessment in hybrid learning contexts. The research aims to evaluate how blockchain-based systems can enhance feedback transparency, reviewer accountability, and student trust in digital assessment processes. Method. Employing a design-based research methodology, a prototype blockchain-enabled peer assessment platform was developed and tested with 92 university students across two hybrid courses. Quantitative and qualitative data were collected through platform analytics, student surveys, and focus group discussions. Results. The results demonstrate that blockchain-based systems can serve not only as secure ledgers but also as ethical architectures for equitable formative assessmentConclusion. The study concludes that blockchain offers a viable mechanism for building equitable, transparent, and tamper-resistant assessment systems in hybrid learning. The research contributes to the growing field of educational technology by introducing a scalable model for decentralized e-assessment.

Abstract

The global imperative for low-carbon development necessitates the formal integration of Nature-based Solutions. Mangrove forests, known for their superior carbon sequestration as “Blue Carbon,” offer a crucial asset, yet their economic potential remains severely constrained by valuation and policy standardization issues. This study aimed to develop a standardized Total Economic Valuation (TEV) framework for Indonesian Blue Carbon and analyze the regulatory requirements for its formal inclusion in the national carbon trading policy. A mixed-methods design utilized biophysical data from two major mangrove regions, employing financial modeling (Discounted Cash Flow and Monte Carlo simulations) to calculate TEV, and policy analysis to assess governance readiness. The TEV averaged USD 21,500 ha, nearly three times the carbon-only value, demonstrating the asset’s premium quality and superior financial stability (45% lower IRR volatility). However, a significant governance bottleneck was identified (Policy Alignment Index 65%), primarily due to a centralized Monitoring, Reporting, and Verification (MRV) system and uncertain community benefit sharing, which actively inhibits market entry. Blue Carbon is validated as a high-integrity, de-risked asset, but its realization depends critically on policy intervention, urging the immediate adoption of the TEV framework and the decentralization of MRV to ensure social equity and accelerate climate finance.
