Abstract
Soil strength is the leading indicator to determine the ability of the soil to withstand changes when under pressure from the outside, for example, when tilling using mechanization tools. Soil compaction can inhibit root penetration and result in impaired nutrient absorption. This study determines how much soil compaction is in sugarcane land at Takalar factory (PG Takalar). The method used in this study was the measurement of soil permeability by direct sampling in the field with calculations based on Darcy's law. Determination of the compressive force gauge on the soil is by direct measurement in the field using a proving ring penetrometer. The results showed that the soil permeability of sugarcane land at PG Takalar was 1.72 cm/hour in the raised beds area and 1.05 cm/hour on the tractor wheel track. The compressive force required by the cone penetrometer to penetrate the soil layer in the bed area is 4.9 MPa at a depth of 0-25 cm and 5.8 MPa at a depth of >25 cm. The compressive force required on the tractor wheel track is 5.8 MPa at a 0-25 cm depth. The cone penetrometer cannot penetrate the soil at a depth of >25 cm. The permeability value and the required compressive force indicate that the soil is compacting.
