Spectral Knowledge Ecosystem for Cultural Heritage: Integration of Spectroscopy, Information Management, and Education Universitas Negeri Jakarta Abstract The preservation of cultural heritage now demands an analytical approach that goes beyond visual digitization towards evidence-based preservation. Spectroscopy is rapidly developing in heritage science because it allows for non-destructive characterization of paper, ink, pigments, and other susceptible materials, while recent studies are moving toward multi-instrument analysis, machine learning, and spectral databases. This article aims to formulate a conceptual model of a spectral knowledge ecosystem that combines spectroscopy, preservation metadata, archive management, and cultural heritage education in the Indonesian context. The study uses systematic integrative review combined with the development of a conceptual model, with thematic synthesis and conceptual mapping as the basis of the analysis. The results of the analysis identified five interdependent layers, namely spectral acquisition, preservation and archival metadata, repository infrastructure, access and partnerships, and education and learning. The proposed framework places spectroscopy not solely as laboratory instrumentation, but as a knowledge infrastructure that supports preservation decision-making, cultural data interoperability, and cross-disciplinary learning. This model contributes to the development of cultural heritage preservation by bridging physics, information management, and education, and is relevant to SDG 4, SDG 9, SDG 11, and SDG 17. Further research is needed to develop Indonesia^s spectral databases, test the application of spectral metadata in libraries and archives, and conduct multisite studies on museums, libraries, and archival institutions Keywords: spectroscopy, cultural heritage, archive, metadata, preservation, Education Topic: Energy and Environmental Physics |
