Abstract
The University of Sumatera Utara (USU) campus is one of the green campuses with a reasonably high diversity of tree species. The ability of stands on the USU Campus to pass water (soil permeability) must be considered for flood prevention. Soil permeability studies in field surveys were carried out by taking soil samples—determination of soil samples for soil permeability properties based on the constant head method. Soil chemical analysis was carried out for soil organic fraction content and physical properties in soil fraction and texture. The analysis showed that saga stands (SS) showed the highest permeability among mahogany stands (MS), cape stands (CS), glodokan tiang stands (GTS), and oil palm stands (OPS).
