Identifying, restoring, and remastering of the Sarinah relief sculpture in Jakarta of Indonesia: the limitations of time, space, and technology

Abstract

The Sarinah historic building transformation project in Jakarta, Indonesia (2020–2022) is an adaptive reuse of the original building formed through a scientific conservation process. Therefore, this research identified, restored, and remastered the Sarinah relief sculpture of alto-relievo (high relief) and mezzo-relievo (medium relief). The invasive demolition method was used to form an atrium space to show the reappearance of the artwork by dismantling two layers of building floors above where the relief was found. The non-invasive method was implemented (a) by identifying damaged mapping artifacts, (b) by restoring, cleaning, and repairing the broken artifacts, and (c) by remastering the 3D model. All activities were supported by digital applications such as the Cartesian diagram coordinates, AutoCAD, Adobe Photoshop, Zbrush software, and close-range photogrammetry. The case study's contribution to heritage science showed the process used to restore alto-relievo and mezzo-relief within time, space, and technology limitations.
