Abstract
This article examines two-dimensional maps that illustrate soil physical properties in Lebong Regency, Bengkulu Province, Indonesia, as a case study. The map displays the distribution of soil properties at various research points, which were selected to represent the different soil layers in the area. The properties discussed include shear wave velocity, plasticity index, saturated unit weight, bulk unit weight, dry unit weight, water content and degree of saturation. The study employed the Kriging interpolation method to analyse data from 457 research points, estimating soil property values between them. The results showed that the highest shear wave velocity values were found in the clay layer of the Central Lebong District, while the highest plasticity index was found in the clay layer of the Lebong Sakti sub-district. The North Lebong sub-district also had the highest bulk and dry unit weight in the clay layer. In contrast, the Pelabai sub-district showed the highest values for saturated bulk density, water content and degree of saturation in the clay layer. This two-dimensional map of soil properties, with its potential to significantly impact infrastructure planning in Lebong Regency, is a crucial tool for geotechnical engineers and consultants. It can help them design safer and more suitable structures based on the soil characteristics of each sub-district, thereby enhancing the safety and efficiency of the region’s infrastructure.
