Abstract
Bujang Valley which is also known as Kedah Tua is believed to be the
earliest entrepot and religious center in the Malaysia. Its role can be proved by the
discovery of archaeological evidence such as the discovery site of Hindu-Buddhist
temples, broken ceramics and many other artefacts related with the trade. The aim of
this study is to identify the buried structure area that has great archaeological
potential at Sungai Batu by using remote sensing and geophysical methods at four
different areas which are SB2ZZ, SB1, SB2 and SB3. Two main characters that can
be observed on the surface are mound area and exposed clay bricks. Remote sensing
was applied to the whole study area by using Landsat5 and Landsat8 data to retrieve
land surface temperature (LST). Then, the LST data were verified by using three
geophysical methods which are 2-D resistivity imaging, magnetic and ground
penetrating radar (GPR) methods. An unmanned aerial vehicle (UAVs) was also
used to capture the aerial photos of the SB2 area to produce the digital surface model
(DSM). SB2ZZ, SB1 and SB2 areas show the results of high resistivity and magnetic
values which are ≥5000 Ωm and ≥50 nT respectively. The high resistivity and
magnetic values indicate the interesting anomaly which is clay bricks due to the
effect of heat at high temperature. Thus, the results of two geophysical methods show
the potential of buried structures leading to an excavation at SB2ZZ area.
