Abstract

In the study of oral tradition, myth is positioned as a sacred story. Being purified, myths are upheld and respected.
Mythological research needs to be conducted to strengthen national resilience in the field of culture and to revitalize local wisdom.
The research on these mythical and historical elements of megalithic site in East Java was conducted with a multidisciplinary
approach, which was a combination of oral, linguistic, and historical research. Ancient myths in East Java have great contribution
to open the mystery of King Ajisaka in 1 Saka or 79 AD in Medang Kamulan community in East Java. Oral tradition and
chronogram in Batu Solor-Ijen slope, informs that the Batu So'on site was built within 11 Saka or 89 AD. King Ajisaka was
replaced by his son King Batu Bajak in 51 Saka or 129 AD. King Batu Bajak was replaced by his son King Batu Gunungin 71
Saka or 149 AD. There is a Malay Proto script carved on Batu So'on. Batu Solor, Mount Budheg, and Kelayar Beach in Pacitan
had better be further investigated for the reconstruction of existing sites. Furthermore, it is necessary to compose the narration of
ancient cultures of Indonesian archipelago and these need to be developed as tourism objects and integrated learning resources
based on oral tradition, historical objects and the beauty of nature.
