This publication discusses the findings of a study on three-dimensional (3D) digital documentation of the Prambanan Temple, located in the Special Region of Yogyakarta, Indonesia. The Prambanan Temple is a cultural heritage site with deep philosophical value, reflecting the advancement of knowledge and local construction skills of its time. It has been recognized as a UNESCO World Heritage Site since 1991.

Given its high historical and cultural significance, the conservation of the Prambanan Temple is of great importance. Moreover, the temple is exposed to various threats, including natural disasters (earthquakes, volcanic eruptions), pollution, and vandalism. 3D digital documentation offers an effective conservation solution as it enables the evaluation of structural vulnerabilities and the development of preservation strategies.

This study proposes a geometric documentation technique for towering concentric temple clusters (TCTCs) — multi-tiered, richly decorated temple groups — by applying an architectural pattern design (APD) approach to guide the use of multi-sensor technologies.

Abstract:

The Prambanan Temple cluster is a world heritage site of great value to humanity, composed of multi-zone arrangements of highly ornamented towering temples in a Hindu architectural design. It is located near the Opak Fault, at the foothills of Mount Merapi, on unstable ground layers, and is surrounded by human activity in Yogyakarta, Indonesia. Its vulnerability necessitates 3D digital documentation for conservation, but its complexity poses significant challenges.

This study aims to address those challenges by introducing the use of architectural pattern design (APD) as a guide for multi-mode sensor placement in documentation. First, APDs were derived from literature to determine the required levels of detail. Then, various sensors and methods of light detection and ranging (Lidar) and photogrammetry were used according to these detail requirements. The resulting point cloud data were processed, integrated, assessed, and validated by demonstrating the existence of APD.

The internal and external quality assessments of each sensor output revealed root mean squared error (RMSE) values ranging from millimeters to centimeters, with terrestrial laser scanner (TLS) achieving the highest accuracy, followed by aerial and terrestrial close-range photogrammetry, and nadir-mode Lidar and photogrammetry. Two relative cloud distance analyses comparing each point cloud model to the reference TLS model produced mean distance values in the millimeter to centimeter range. Visually, each point cloud model from the various sensors successfully complemented one another.

Thus, the proposed approach shows strong potential for the documentation of complex heritage sites. These results provide a solid foundation for further analysis, particularly in assessing structural vulnerabilities and shaping conservation strategies.

Tuesday, February 11th, 2025 marked the start of Professional Studio II from the Professional Architect Education Program that is being held in the second semester of Academic Year 2024/2025. There are differences on how the scheme of Professional Studio II is conducted this year compared to the previous years where students will be undergoing internship under an architectural firm. In this year’s studio, the students will be directly guided by external architects in preparation to participate in an open international architectural competition called C40: Reinventing Cities.

On the first day of the studio, architect Rezza Rahdian, S.T. and architect Widi Cahya Yudhanta, S.T., M.Sc. were both present on the campus of Department of Architecture and Planning (DTAP) Universitas Gadjah Mada to give an introduction and to hold an interview session with the students. The aforementioned interview was held to determine the students into two different teams to participate in the competition. With a site located in Milan-Segrate, Italy, the participants of the competition are required to design Marconi District Student Housing.

As of March 20th, the current PPAr students have completed each of their team’s registration to participate in C40: Reinventing Cities. In addition, guidance by the architects have proceeded in routine weekly by utilizing the allocated time for Professional Studio II course. The unconventional location of the site, added by direct guidance provided by external architects, are expected to give the students a novel knowledge while also enhancing their experiences in their journey of becoming an architect.

This activity and the content given through this year’s Professional Studio II go in hand with SDG 4: Quality Education, SDG 11: Sustainable Cities and Communities, and SDG 13: Climate Action.
