The research method used is the classification of Van Zuidam, 1985 and Classification of the Shape of the Earth (BMB). Analysis of the Van Zuidam classification produces morphometrics with slopes of 4° - 14.6°, morphography with parallel and dendritic flow patterns, morphogenetic with Fluvial, Structural, Denudational landforms. Analysis of the classification of the Earth's surface produces landscapes in the form of river plains and lakes, mountainous volcanic landscapes, and folded mountainous landforms.
