Abstract The aim of this research is to establish an infiltration rate model for land uses including smallholder rubber plantations, rice fields, and shrubs. The infiltration rate data was analyzed using the Horton equation model. Every ten minutes, the water level drops. The results of the research show that the infiltration rate model on smallholder rubber plantation land is is f = 7.2 + (10 – 7.2) e 2.64t , whereas on small oil palm plantation land it is It is f = 7.98 + (10 – 7.98) e −2.68 t on smallholder latex plantation land; f = 9.13 + (10 – 9.13) e −5.20 t on rice fields; and f = 4 + (10 – 4) e −2.96 t on bush land. In smallholder rubber plantations, the infiltration rate is classified as moderate at 2.06 cm/hour; in rice fields and smallholder plantations, it is relatively slow, namely 0.87 cm/hour and 1.87 cm/hour, respectively. The infiltration rate in bush land is relatively fast, namely 6.56 cm/hour. With an infiltration rate of 1.87 cm/hour on smallholder oil palm plantations and 0.87 cm/hour.
