Abstract

Research of surface topography characteristics and elements of sand from the flash flood in North Luwu Regency was motivated by the abundance of sand due to the natural disaster that occurred in mid-2020 in South Sulawesi, Indonesia. The aim ware to determine the surface topography and elements of the sand, so that it can be used as a reference for its use. The test method used was SEM-EDX. The results obtained show that the surface of the sand is coarse and not hollow, while the elements contained in the sand based on Weight (%) and Atomic (%) respectively are O (49.90% and 61.00%), Si (25.14% and 17.51%), K (9.39% and 4.70%), Al (8.37% and 6.07%), C (6.05% and 9.86%), Na (0.94% and 0.80%), Fe (0.21% and 0, 07%). The conclusion obtained was that the sand from the flash flood in North Luwu Regency includes silica sand.
