ACCURACY ANALYSIS OF GPS TECHNOLOGY IN IDENTIFYING THE QIBLA DIRECTION OF DARUSSALAM MOSQUE, MAKASSAR

Abstract

This research analyzes the accuracy of GPS technology in determining the Qibla direction of Darussalam Mosque, located in Mampu Subdistrict, Wajo District, Makassar City. The core problem addressed in this study is the uncertainty surrounding the mosque’s Qibla orientation, which was initially set by Kodam XIV Hasanuddin but has never been systematically re-measured using scientific methods. Employing a qualitative field research design with an Islamic astronomy (Ilmu Fal ak) approach, data were obtained through observation, documentation, and interviews with mosque administrators, community figures, and relevant stakeholders. Measurements were conducted using several GPS-based applications such as Google Maps, Qibla Finder, Qiblat Compass, and mobile GPS sensors. The results indicate that the latitude and longitude readings from the four tools were relatively consistent, with minor discrepancies caused by satellite signal instability, magnetic interference, and the dense urban environment surrounding the mosque. Overall, the study highlights the importance of integrating modern geospatial technology and classical astronomical principles to enhance the reliability of Qibla orientation in urban mosque settings.
