Abstract. Soil infiltration is the process of vertical entry of water into the soil through the soil surface. The process of soil infiltration can help meet the need for water and reduce the occurrence of soil erosion and flooding. Soil infiltration is influenced by several soil properties, namely soil texture, organic C, porosity, bulk density, permeability and aggregate stability. This research was conducted in Lhoksukon District, North Aceh Regency on residential land use, rice fields, mixed gardens and oil palm plantations by measuring the value of the soil infiltration rate in the field and assessing soil properties that affect the rate of infiltration. The results of this study indicate that the value of the soil infiltration rate in flood-prone areas in Lhoksukon District is classified as very slow, slow and rather slow. The value of very slow infiltration rate is at the points TR4-Oil Palm, R3-Mixed Gardens and SR3-Settlements, the value of the slow infiltration rate is at points TR2-Sawah, R1- Settlements and SR2-Paddy, and the value of the rate of infiltration is rather slow is at point TR1-Mixed Gardens, R3-Settlements, R2-Paddy, R4-Oil Palm and SR2-Mixed Gardens. The factors that affect the rate of infiltration in flood-prone areas in Lhoksukon District, North Aceh Regency are texture, C-organic and soil porosity.
