Abstract
The architectural model of a tree or tree building relates to the pattern of stem growth, branching and formation of thermine shoots. This architectural model affects water absorption through crown outflow and stem flow. The Ujung Pancu forest area of Aceh Besar Regency is the place where research was conducted on “Tree Architecture Models in the Lampageu Village Forest Area Ujung Pancu Aceh Besar Regency” in June 2023. This study aims to determine the models of tree architecture in the Ujung Pancu forest area on the amount of crown outflow and stem flow. Thus, each additional rainfall will increase the crown outflow on each tree architecture model. This data was obtained using the Transect (Line Transect) method and direct observation in the field (field survey), with a transect line made along 10x100 meters dividing the forest area with a transect size of 10 m to the right and to the left and a road length of 100 m. The results showed that the Ujung Pancu rainforest area of Aceh Besar Regency has a variety of plants. There are 7 tree architecture models from 15 species in the Ujung Pancu forest area, Aceh Besar Regency, namely, rauh, leuwenberg, scarrone, corner, koriba, massart, troll, with the dominant architectural models namely scarrone and rauh. The rauh and scarrone model has the characteristics of rhythmic growth (simultaneously), with branches that are orthotropic (growing towards the direction or), the first stem can grow indefinitely, vase-shaped canopy, where the lower canopy is narrow and the higher it will widen will affect surface flow, infiltration, interception and erosion
