Prof. Nur Islami
University of Riau, Indonesia

Nur Islami received his B.Sc. from Universitas Riau and his M.Eng from Institut Teknologi Bandung (ITB), Indonesia, and Ph.D. degrees from University of Malaya, Malaysia. He worked in Caltex Pacific Indonesia (an Oil Company) in 1997-2000. He joined Universitas Riau, Indonesia as Lecturer from 2000 until now. He was as Visiting Senior Lecturer in University of Malaya (70 QS World Ranking), Malaysia from 2006 to 2015. During this period (2006-2015) he also was an instructor and consultant for the environment and exploration company that was related to the geophysics. He received the Professor since 2020 in the field of Geophysics from Universitas Riau, Indonesia. Now, Prof Nur Islami, Ph.D is the Vice President of Physics Society of Indonesia Riau. He is a reviewer in several Scopus-Indexed Journals and also associate editor of Arabian Journal of Geoscience. His research is correlated with the geophysical method for the environment and earth resources exploration. Prof Nur Islami has many publications in the reputed Scopus-indexed journals. 


Speech title "An valuable approach to study groundwater contamination in a shallow aquifer system"

Abstract-Groundwater is sometimes contaminated by the presence of heavy metals in the aquifer system. In this research, a study to map the possibility of areas contaminated by heavy metals using the integration of geoelectrical resistivity, geochemical and soil analysis methods is presented. Chemical analysis was carried out on soil samples obtained from two new wells and from selected sites. Chemical analysis of water and soil results from the two new wells was used as a calibration in resistivity interpretation. Correlation between concentration of the Fe in the soil and the concentration of Fe in the groundwater samples showed a positive linear trend; However, the concentration of Al in the soil has nothing to do with Al content in groundwater. Finally, the possibility of high-heavy metal zones in the aquifer system is easily described by the geoelectrical resistivity distribution presented in the form of a deep wedge extending from the Boundary Range Composite Batholith in the north to the northwest of the study area.
