Research and Innovation Agency (
BRIN
) reveals the results of the latest research on the dynamics of tropical Earth through the soil layers of Java Island.According to him, the dynamics of tropical Earth affect life
ancient humans
in Southeast Asia.
In the Internationale de Sciences Préhistoriques et Protohistoriques (UISPP) Inter-Congress Conference 2025, the theme was “Asian Prehistory Today: Bridging Science, Heritage, and Development”.

The research is entitled ”
Paleoenvironment Reconstruction of the Lower Kaliglagah Formation in the Palaeontological Site Bumiayu, Brebes, Central Java
” it depicts an environmental transition between shallow seas and fluvial swamps around 2.4 million years ago, when the Earth experienced global cooling.
“Bumiayu records glacial oscillations that repeated phases when sea levels dropped drastically and Java Island was connected to mainland Asia,” said Head of the BRIN Archaeometric Research Center, Sofwan Noerwidi, as reported on the BRIN website, Thursday (6/11).
According to him, the results of this research have succeeded in providing a concrete portrait of how climate change can shape the landscape and influence the distribution of ancient fauna.
He emphasized integrated methods of stratigraphy and isotope analysis, allowing researchers to study the history of tropical environments with new levels of accuracy.
Ni Luh Gde Dyah Mega Hafsari, researcher at the BRIN Research Center for Environmental Archaeology, Maritime and Sustainable Culture, through a presentation ”
Digging Java’s Middle Pleistocene: Chronostratigraphic, Palaeoenvironmental, and Palaeoanthropological Data from the New Sogen Locality
“, revealing that vegetation changes and volcanic activity overlapped with early hominins.
Through chronostratigraphy and geochemistry, data is collected to expand scientific understanding.
“The chronostratigraphic and geochemical data collected expands understanding of the relationship between climate change, then fauna migration, and possible distribution routes of ancient humans in the eastern region of Java,” he said.
Taufiqurrahman Setiawan, researcher at the BRIN Archaeometric Research Center also discussed the study ”
Regional Responses to Shared Traditions: The Hoabinhian Techno-Complex and the Case of Gua Mabitce, Western Coast of Aceh
.”
He talked about the Hoabinhian stone tool tradition in Aceh showing how humans continued to adapt to the humid tropical environment after the end of the Ice Age.
In describing the relationship between geology, climate and past cultures, the synergy of these three studies shows the integration of BRIN’s research.Indonesian scientists are rereading the history of the earth stored in the soil layers from Bumiayu to Sogen.
They discovered how humans, animals and nature once collaborated to overcome extreme change.
BRIN is committed to building sustainable archaeological science by encouraging cross-country research collaborations to understand the dynamics of tropical environments and their impact on human evolution.
Through the UISPP 2025 forum, a multidisciplinary approach is realized that combines archaeometry, geology and biogeochronology in building Indonesian archaeological science.
