【 摘 要 】

The discovery of the "J" letter-shaped brick structure (also called the Terung Temple) in Terung Wetan Village in 2012 is thought to be a heritage of the Majapahit Kingdom era. However, there is no further research to figure out the distribution of structures in the area. Geophysical surveys with 2D resistivity geoelectric methods-dipole-dipole configuration were carried out in the Site of Kadipaten Terung, Terung Wetan Village, Krian, Sidoarjo Regency to map the distribution of existing subsurface structures. Judging from the location of the Terung Temple, line 1 with the north-south direction on the west side with a length of 62 meters had a resistivity anomaly value of 13.2-60 Ωm at a depth of 1-3.67 m; line 2 with the southwest-northeast direction on the northwest side with a length of 46.5 meters had a resistivity anomaly value of 13.8-75 Ωm at a depth of 1-2.75 meters; line 3 with the northwest-southeast direction on the southwest side with a length of 46.5 meters had a resistivity anomaly value of 12.7 - 75 μm at a depth of 1-2.75 meters; line 4 with the east-west direction on the south side had a resistivity anomaly value of 15-75 Ωm; and line 5 with north-south direction on the east side with a length of 62 meters had a resistivity anomaly value of 15.7-100 Ωm. These anomalies are indicated as subsurface brick structures scattered throughout the research trajectories and it had been the continuity of the Terung Temple into the west and south.
