Abstract

In the previous research in Badut temple, it resulted in the conclusion that on the research path, there is a Badut temple foundation, at a depth of 0 m -1.5m, which is square wide. The results of this study require further research to detect the presence of a cavity zone because the presence of cavity zones has the potential for subsidence of the temple foundation. This study aims to determine the distribution of cavity zones under the temple foundation. Research in the first location around the temple building was carried out by scanning 8 straight lines, then combined and analyzed. Based on the results of the analysis, it is found that the cavity zones are spread from trajectory 1-8. The largest cavity zone is located in the corner of the intersection of lanes 1 and 2. The second location research was carried out in the pool in front of the temple; the results showed that the pool floor was dominated by the cavity and watery zone. Only a few points showed buried rock, which was shown by reddish-yellow color. Based on the data analysis, it can be concluded that around the temple, there are still many cavity zones, and there are still some buried rocks. As for the pool area, it is dominated by a cavity zone, so it is possible that there is still a lot of empty space under the ground floor of the pool, and it is watery.
