This week (21-25 January 2019), Dean of FMIPA UB, Drs. Adi Susilo, M.Sc., Ph.D. with researchers and MalangTIMES conducted an exploration called the Malang Ancient Expedition. This expedition is focused on knowing the potential that exists in Malang City by revealing the ‘history of science’, Malang Regency and Batu City. In addition, this activity was also supported due to a lack of literacy regarding the state of origin of the existing poor regions.

The activity starts from Malang City, the Team gets information that Malang City was once a mountain slope. Because of getting lava from Mount Arjuna and Wilerang, the area of ​​Malang City is a plateau. This is corroborated by evidence of the sand found when digging thirteen meters deep.

The Batu and Pujon City areas – almost the same as Malang City – became highlands because of volcanic eruptions. Apart from Mount Arjuna and Wilerang, this area gets lava from Mount Panderman, Gunung Kawi and Gunung Butak. In addition, the presence of hot water sources proves that the Batu City and Pujon areas are close to volcanic lava.

The southern part of Malang Regency was once a volcano mountain inside the ocean. This area is often found in coral and fish fossils. Unlike the areas of Malang City, Pujon, and Batu City which were only 5 million years old, the mountains in the southern Malang area have a fairly old age, 19-20 million years ago.
