Abstract

The circular economy (CE) has moved to the center of sustainability-driven innovation, with agriculture playing a pivotal role due to its large biomass flows and potential for resource optimization. This study investigates how CE practices relate to sustainable innovation, specifically highlighting value creation for “ergo-iconic” agricultural products—goods that uniquely combine ergonomic functionality (usability, durability, and human-centered design) with culturally embedded, sustainability-oriented identity attributes (place-based branding, heritage value, and symbolic meaning). Employing a qualitative exploratory design in Banten, Indonesia, we conducted semi-structured interviews with ten key informants comprising five agro-industry practitioners, three industry analysts, and two NGO representatives. We complemented this primary data with rigorous document analysis to ensure a holistic understanding of the context. Thematic analysis and triangulation were employed to establish the credibility of the findings. The results indicate that circular business models not only reduce waste but also serve as catalysts for broader innovation processes. Three primary drivers consistently emerged: (1) stakeholder engagement, (2) cross-sector collaboration, and (3) the adoption of environmentally friendly technologies. Building on these insights, we propose the CircAgriResilient Nexus (CAR-Nexus)—a comprehensive framework that conceptualizes circularity as a dynamic nexus connecting four pillars: Circularity, Agri-Innovation, Resilience, and Nexus Governance. CAR-Nexus differs from existing sustainable circular bioeconomy models by explicitly positioning resilience as a core system capability and by integrating a provisional Resilience Index Score (RIS)—a conceptual tool that synthesizes resource efficiency, social progress, and economic robustness to guide balanced assessment of circular transitions. This framework clarifies how circular resource flows, eco-innovation, and inclusive governance jointly enhance market, environmental, and social value within the Industry 4.0 era. The study contributes theoretically by articulating an integrative CE-innovation-resilience nexus tailored specifically to agri-food systems, and practically by outlining actionable levers for firms and policymakers to accelerate circular transitions in developing economies.

Abstract

Research on adaptive learning systems (ALS) in mathematics education has increased substantially in recent years; however, existing studies remain fragmented across system types, educational levels, and implementation contexts. Most prior reviews have focused either on technological characteristics or learning outcomes, providing limited insight into how adaptive learning systems are systematically implemented and synthesized within mathematics education. Addressing this gap, this study examines adaptive learning systems in mathematics education through an integrated bibliometric mapping and systematic literature review. A systematic literature review was conducted and reported in accordance with PRISMA guidelines to identify, screen, and select relevant studies from major academic databases. Bibliometric mapping analysis using VOSviewer was then employed to explore publication trends, keyword co-occurrence, and thematic structures within the selected literature. The findings indicate that adaptive learning systems generally contribute positively to mathematics learning outcomes; however, their effectiveness is closely associated with pedagogical integration and teacher preparedness rather than technological sophistication alone. A phased implementation pattern is observed, beginning with teacher-led enhancement approaches and progressing toward more technology-mediated models. While AI-based systems demonstrate strong potential, moderately complex adaptive systems appear more feasible for institutions with limited resources. These findings highlight the importance of pedagogical readiness in the adoption of adaptive learning systems and suggest directions for future research, particularly in underrepresented educational levels.
