Abstract

Majapahit is one of the great kingdom in archipelago that supposedly the kingdom centre was located in Java Island so that the historical heritage was scattered and many a subject of research of the archaeologists were still running. Plawangan site which became the object of community service activities was located in the village of Suwaluh, Balung Bendo, Sidoarjo, East Java and thought to be relics of the Majapahit Kingdom of the historical study of ancient rocks and a tiny fraction excavations that have been carried out independently. Hypotheses about the broad of Plawangan site object was approximately 3 hectares. Integration studies that conducted were the application of Geophysical Ground Penetrating Radar methods (GPR), Very Low Frequency (VLF) and aerial photographs. Measurements with both of Geophysics method aimed to detect the presence of objects, patterns of distribution and depth of prehistoric objects that have not been exposed in the bottom surface Plawangan Site. Application of aerial photographs was expected to map the surface region Plawangan Site. The result of this integration studies was expected to give comprehensive and clear information about the object of Plawangan site Sidoarjo so that it became the initial materials for giving socialization and educational to the public and the government for taking the policy that related with environmental management and urban planning. The expected impacts were the concern and support of the community and the district or province government in excavation sustainability efforts and protection of prehistoric objects in Plawangan site or it can be set into cultural heritage. Results of GPR and VLF methods showed a good image of hidden Plawangan site so that we can interpret and delineate the geometry. Aerial photographs also showed that the sediment of Plawangan site is characterized by small mounds with vegetation on it.
