One factor that influences the water balance on earth is the presence of the rain factors. The Hydrological cycle is a process of water that is evaporated and if the atmosphere allows, water will fall as rain. Interception is an important factor in the hydrological cycle. With the process of interception, rain water that reaches the ground surface becomes reduced. The amount of interception is influenced by land use in a sub-watershed. This research was conducted in the Krueng Jreu sub-watershed, located in Aceh Besar District with an area of 23,189.53 Ha. Land use at this location is generally intended for plantations, wetland agriculture, protected forests, and rural settlements. Most of the citizen around the research location, work as farmers, such as farmers of rice, corn, peanuts, oil palm, and others. In comparison to all types of plants, corn is one of the dominant plants developed in this area. The purpose of this research is to find out the value of interception in maize plants. The value of interception in maize plants aged 1-3 months was analyzed by making a Mini Hydrological Watershed model to obtain a regression equation, where this equation is used to see the interception of maize intercepts on rainwater rainfall observations of 19 variants of observational data from 3 months of research. The amount of interception in maize plants obtained based on the Mini Hydrology Watershed model with logarithmatic regression is 17.62 mm from 205.950 mm of total rainfall. © Published under licence by IOP Publishing Ltd.
