Penetrating Radar (GPR) dengan frekuensi 250 MHz dan 700 MHz. Penggunaan metode GPR memungkinkan pemetaan struktur bawah permukaan secara non-destruktif, penting untuk melindungi situs bersejarah yang terancam oleh pembangunan modern dan aktivitas wisata.Data GPR diperoleh dari tiga lintasan di kawasan penelitian dengan panjang lintasan 26-28 meter. Radargram yang dihasilkan dari frekuensi 700 MHz menunjukkan detail lapisan bawah permukaan dengan lebih jelas dibandingkan dengan radargram frekuensi 250 MHz. Lapisan bawah permukaan diidentifikasi didominasi oleh material pasir berkerikil pada kedalaman 20-60 cm. Namun, tidak ditemukan objek arkeologis signifikan di area survei, meskipun ada indikasi gangguan sinyal yang disebabkan oleh faktor-faktor seperti akar pohon dan keterbatasan alat pada beberapa bagian lintasan.Hasil penelitian ini menyimpulkan bahwa metode GPR efektif untuk pemetaan bawah permukaan di kawasan Komplek Gunongan, meskipun tidak ada penemuan arkeologis signifikan. Diperlukan survei tambahan dengan lintasan lebih variatif dan pendekatan multi-arah untuk mengoptimalkan deteksi objek arkeologis.

This study aims to identify the subsurface layers at the Gunongan Complex archaeological site in Banda Aceh using the Ground Penetrating Radar (GPR) method with 250 MHz and 700 MHz frequencies. The use of GPR allows for non-destructive mapping of subsurface structures, crucial for preserving this historical site, which is threatened by modern infrastructure development and tourism activities. GPR data were collected from three survey lines within the study area, each with a length of 26-28 meters. The radargrams generated at 700 MHz frequency revealed more detailed subsurface layers compared to the 250 MHz frequency. The subsurface layers were predominantly composed of gravelly sand at depths of 20-60 cm. However, no significant archaeological objects were identified in the surveyed area, although there were indications of signal disturbances caused by factors such as tree roots and equipment limitations in certain sections of the survey lines. The results conclude that the GPR method is effective for subsurface mapping in the Gunongan Complex area, despite the absence of significant archaeological findings. Additional surveys with more varied survey lines and a multi-directional approach are recommended to optimize the detection of archaeological objects in future investigations.
