Abstract

Studi arkeologi merupakan salah satu upaya penting untuk mengungkap dan memahami persebaran batuan candi yang masih terpendam. Penelitian ini bertujuan untuk mengetahui posisi persebaran candi di Situs Tondowongso, Desa Gayam, Kec. Gurah, Kab. Kediri dengan menggunakan metode Self-Potential (SP). Metode SP dipilih karena kemampuannya mendeteksi variasi konduktivitas listrik alami di bawah permukaan tanah, yang dapat mengidentifikasi keberadaan struktur batuan dan artefak arkeologis. Pengukuran metode SP menggunakan pendekatan fixed-base dengan spasi antar titik pengukuran sebesar 2 m dan 8 lintasan yang tersebar pada Situs Tondowongso. Selanjutnya, data SP difilter menggunakan metode Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN) untuk menghilangkan noise pada data SP. Data SP terfilter yang terindikasi anomali diinversi menggunakan algoritma Flower Pollination Algorithm (FPA) untuk menghasilkan parameter-parameter data SP. Hasil yang diperoleh menunjukkan adanya anomali yang diidentifikasi sebagai distribusi candi pada kedalaman 1,4 ± 0,1 hingga 3,9±0,2 meter, dengan perkiraan bentuk anomali berupa silinder vertikal dan silinder horizontal. Kedalaman ini berkorelasi dengan metode VLF yang memperkirakan kedalaman sekitar 5 meter. Sementara itu, arah persebaran candi diduga menuju ke selatan, berdasarkan korelasi dengan metode magnetik yang menafsirkan sumber anomali sebagai situs yang telah diekskavasi.

Archaeological study is one of the important efforts to reveal and understand the distribution of buried temple rocks. This study aims to determine the position of the distribution of temples at the Tondowongso Site, Gayam Village, Gurah District, Kediri Regency using the self-potential (SP) method. The SP method was chosen for its ability to detect variations in natural electrical conductivity below the ground surface, which can identify the presence of rock structures and archaeological artifacts. The SP method measurements used a fixed-base approach with a spacing between measurement points of 2 m and 8 trajectories spread across the Tondowongso Site. Furthermore, the SP data was filtered using the Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN) method to remove noise in the SP data. The filtered SP data that indicated anomalies were inversed using the Flower Pollination Algorithm (FPA) algorithm to produce SP data parameters. The results obtained indicate the presence of an anomaly identified as a temple distribution at a depth of 1.4 ± 0.1 to 3.9 ± 0.2 meters, with the approximate shape of the anomaly being a vertical cylinder and a horizontal cylinder. This depth correlates with the VLF method which estimates a depth of about 5 meters. Meanwhile, the direction of the temple distribution is thought to be towards the south, based on correlation with the magnetic method that interprets the anomaly source as an excavated site.
