Abstract
Candi Tikus di Mojokerto merupakan situs arkeologi penting dengan potensi struktur terpendam yang belum sepenuhnya terungkap. Penelitian ini bertujuan memetakan persebaran, dimensi, dan kedalaman struktur bawah permukaan menggunakan metode Ground Penetrating Radar (GPR) dan Electrical Resistivity Tomography (ERT). Kedua metode dipilih karena bersifat nondestruktif dan mampu mendeteksi struktur terpendam berdasarkan refleksi gelombang elektromagnetik serta sifat kelistrikan batuan. Hasil GPR menunjukkan adanya anomali refleksi dengan amplitudo tinggi yang tersebar secara acak pada kedalaman 1 sampai 2 meter dari permukaan tanah. Anomali diinterpretasikan sebagai dinding yang membentuk pola linear dan tegak lurus di petak A, B, E, dan F. Dimensi anomali bervariasi mulai dari 1×5 meter sampai 10×18 meter. Pada kedalaman lebih dari 3 meter, sinyal GPR melemah akibat atenuasi oleh tanah basah sehingga struktur tidak lagi terdeteksi jelas. Oleh karena itu, ERT digunakan untuk memetakan anomali resistivitas tinggi di kedalaman tersebut. Hasil ERT menunjukkan indikasi keberadaan saluran air di blok utara dengan lebar kurang lebih 1 sampai 2 meter menuju arah utara. Korelasi spasial antara anomali GPR dan ERT memperkuat interpretasi keberadaan struktur arkeologi di beberapa lokasi, khususnya di halaman depan petak B dan halaman belakang petak F. Hasil ini menunjukkan bahwa integrasi GPR dan ERT mampu memberikan indikasi kuat keberadaan struktur terpendam di Situs Cagar Budaya Petirtaan Candi Tikus. Temuan ini diharapkan dapat menjadi acuan pelestarian situs serta mengembangkan studi geofisika arkeologi di Indonesia.

Candi Tikus in Mojokerto is a significant archaeological site with potential subsurface structures that have yet to be fully uncovered. This study aims to map the distribution, dimensions, and depth of underground structures using Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT). These non-destructive methods were chosen for their ability to detect buried structures through electromagnetic wave reflections and the electrical properties of subsurface materials. GPR results reveal randomly scattered high-amplitude reflection anomalies at depths of 1 to 2 meters below the surface. These anomalies are interpreted as walls forming linear and perpendicular patterns in plots A, B, E, and F, with dimensions ranging from 1×5 meters to 10×18 meters. At depths greater than 3 meters, the GPR signal weakens due to attenuation by moist soil, making the structures less clearly detectable. Therefore, ERT was employed to map high-resistivity anomalies at these deeper levels. The ERT results indicate a possible water channel in the northern block, approximately 1 to 2 meters wide, extending northward. Spatial correlations between the GPR and ERT anomalies strengthen the interpretation of archaeological structures in several locations, particularly in the front yard of plot B and the backyard of plot F. These findings demonstrate that integrating GPR and ERT provides strong indications of buried structures at the Candi Tikus heritage site. These findings are expected to support site preservation efforts and contribute to the development of archaeological geophysics in Indonesia.
