The Undergraduate Study Program for Applied Surveying and Basic Mapping Technology (TSPD) UGM Vocational School pioneered the efforts to preserve Prambanan Temple from a geometric perspective by monitoring the movement or deformation of the temple and documenting the 3D shape of the temple in detail, thoroughly, and up to date.
Collaborating with the Yogyakarta Cultural Heritage Preservation Agency (BPCB), the TSPD Study Program conducted research activities on Deformation Monitoring and 3D Digital Documentation of Prambanan Temple using Lidar Drones Terrestrial Laser Scanners on Tuesday (31/8).
“Advanced tools support this research in the form of Lidar Microdrones Drones from PT Geotronix and Terrestrial Laser Scanners from PT. ASABA,” said the Head of the TSPD Applied Undergraduate Study Program as well as a lecturer in Geodetic Engineering UGM, Ir. Rochmad Muryamto M.Eng.Sc.
He conveyed that this research activity is a routine activity that lecturers must carry out in fulfilling the tridharma. With the support of PT Geotronix and PT. ASABA, in this study, several aspects that had not been previously monitored could be investigated.
Director of PT. Geotronix, Fajar Adi, said that PT. Geotronix is committed to supporting education and research activities at universities in Indonesia, one of them is UGM.
“Lidar drones are used to get data in the form of point clouds that can display objects in detail and quickly. In general, drones only display images in the form of images or photos,” he said.
Fajar added that this lidar drone emits a safe laser beam reflected by objects below it so that an image of actual conditions is formed. In addition to research at Prambanan, this lidar drone is also used for mapping the campus area at UGM.
Research with support from PT. Geotronix is a manifestation of the previous memorandum of understanding between UGM and PT. Geotronix.
Wahyu Widiat Miko as the technical support manager of PT ASABA revealed that the 3D documentation of Prambanan Temple is expected to be useful to facilitate the restoration process if one day there is damage, for example damage due to an earthquake.
Dra. Zaimul Azzah M.Hum., Head of BPCP DIY, also enthusiastically welcomed the research conducted by the UGM TSPD Study Program. The results of this study, he explained, can be used for temple operational and disaster management.
“The temple building can be restored according to its original size and shape to maintain the cultural historical value of Prambanan Temple so that the next generation can enjoy it,” said Zaimul.
The UGM TSPD Study Program is committed to researching the data processing to realize expectations for preserving the Prambanan Temple culture. Later, the research results are expected to be used by BPCB DIY.
