Heritage conservation in the digital era offers unparalleled opportunities for preserving cultural heritage through advanced methodologies. This study compares interdisciplinary conservation efforts for the Tulou of Fujian, China, and the Sangiran Early Man Site in Central Java, Indonesia, both are UNESCO World Heritage Sites, each with unique historical and cultural significance. The Tulou, large communal earthen buildings, are emblematic of the Hakka people’s architectural ingenuity. These structures feature thick earthen walls and wooden frameworks, providing both residential space and defense. Conservation challenges include preserving traditional construction techniques, ensuring structural stability, and adapting to modern living standards. Digital documentation methods, particularly utilizing resources such as the Fujian Tulou Digital Panorama, are crucial in accurately capturing the Tulou’s complex geometries and construction details. This digital data aids in monitoring structural health, planning restoration projects, and educating the public about the Tulou’s cultural significance. The Sangiran Early Man Site offers insights into early human evolution with its rich collection of Homo erectus fossils and ancient cultural artifacts. Conservation at Sangiran focuses on protecting and documenting these invaluable finds while ensuring the site’s sustainability. Digital techniques, including the Sangiran Virtual Museum, are used to map excavation areas, document fossil locations, and create virtual reconstructions of prehistoric environments. These tools enhance the management and interpretation of the site, making it accessible for educational and research purposes. This interdisciplinary project highlights how digital tools transform heritage conservation across different contexts. By comparing these methodologies, the project aims to develop best practices that integrate traditional knowledge with modern technology, ensuring the sustainable conservation of diverse heritage sites.
