Abstract

Kompleks Situs Bhre Kahuripan merupakan situs peninggalan Kerajaan Majapahit yang dinilai memiliki peranan penting dalam sejarah Kerajaan Majapahit. Beberapa tahapan ekskavasi telah dilakukan di situs ini. Hasil ekskavasi yang dilakukan pada rentang 2019–2024 menunjukkan adanya sejumlah struktur batu bata yang terkubur pada kedalaman beberapa meter di Sektor Barat dan Sektor Putuk. Beberapa struktur tersebut diperkirakan memiliki kemenerusan hingga Sektor Lapangan. Sektor Lapangan menjadi salah satu area yang belum diekskavasi secara keseluruhan di situs ini. Oleh karena itu, diperlukan data persebaran struktur terkubur di Sektor Lapangan sebagai acuan untuk tahap ekskavasi berikutnya. Analisis pola persebaran tersebut dapat dilakukan dengan metode geofisika seperti metode gradiometer magnetik dan metode Ground Penetrating Radar (GPR). Kedua metode ini banyak digunakan untuk analisis pola persebaran struktur terkubur di sejumlah situs arkeologi. Berdasarkan hasil penelitian ini, didapatkan pola anomali gradien magnetik yang berada pada sisi barat dan timur area penelitian. Anomali tersebut ditunjukkan oleh nilai gradien magnetik yang lebih tinggi. Sementara itu, anomali GPR sebagain besar berada pada sisi barat dan utara area penelitian, serta sejumlah anomali berukuran lebih kecil pada sisi timur area penelitian. Anomali GPR ditandai dengan nilai amplitudo yang lebih tinggi pada time slice 10 ns. Pemetaan persebaran struktur terkubur di area penelitian dilakukan dengan mengintegrasikan hasil interpretasi dari hasil metode gradiometer magnetik dan GPR. Hasil pemetaan anomali dari kedua metode secara garis besar memiliki kemiripan letak dan orientasi. Berdasarkan dimensinya, anomali tersebut diduga merupakan fondasi dinding dan fondasi gapura.

The Bhre Kahuripan Site Complex is a Majapahit Kingdom heritage site that is considered to have played an important role in the history of the Majapahit Kingdom. Several stages of excavation have been carried out at this site. The results of excavations conducted between 2019 and 2024 show the existence of a number of brick structures buried several meters deep in the West Sector and Putuk Sector. Some of these structures are estimated to extend into the Field Sector. The Field Sector is one of the areas that has not yet been fully excavated at this site. Therefore, data on the distribution of buried structures in the Field Sector is needed as a reference for the next phase of excavation. The analysis of the distribution patterns can be conducted using geophysical methods such as the magnetic gradiometer method and Ground Penetrating Radar (GPR) method. Both methods are widely used for analyzing the distribution patterns of buried structures at numerous archaeological sites.Based on the results of this study, magnetic gradient anomalies were found on the western and eastern sides of the study area. These anomalies were indicated by higher magnetic gradient values. Meanwhile, GPR anomalies were mostly found on the western and northern sides of the study area, with a number of smaller anomalies on the eastern side of the study area. GPR anomalies are characterized by higher amplitude values at the 10 ns time slice. Mapping of the distribution of buried structures in the study area was carried out by integrating the interpretation results from the magnetic gradiometer and GPR methods. The mapping results of anomalies from both methods generally show similarities in location and orientation. Based on their dimensions, these anomalies are suspected to be wall foundations and gate foundations.
