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.
