| Abstrak Soil is a natural resource that cannot be easily replaced. If the soil is degraded or damaged, it will be difficult to renew because it requires a long recovery time. It is necessary to pay attention to the physical properties of the soil and know its characteristics to protect the soil, especially from damage that might occur when the soil is used. The aim of this research is to determine the physical condition of the soil in the former gold mining area in Malomba Village, Dondo District, Toli-Toli Regency. This research was carried out for 2 months. Starting from May to July. Soil sampling was carried out in Malomba Village, Dondo District, Toli-Toli Regency. The method used was a survey method, sampling was carried out purposively (intentionally) at three slope points, namely: Peak, Ridge and Valley. The parameters observed are, Texture, Permeability, Bulk Density, Porosity and C-Organic. The results of this research show that the physical condition of the soil texture at the research site has various texture classes, peaks 22.4%, ridges 9.7%, valleys 2.3%. Permeability at the peak is 0.13 cm/hour, the back is 3.28 cm/hour, the valley is 0.19 cm/hour. Bulk density with a peak percentage of 1.54 gr/cm3, back 1.55 gr/cm3, valley 1.46 gr/cm3. Porosity with a peak percentage of 41.90%, back 44.98%, 41.46% while valleys with a percentage of 41.46%. in C-Organic, namely at the peak 2.03%, back 1.37%, for the valley 0.66%.
