Abstract

Changes in land cover contribute significantly to alterations in temperature and the environment. Human activity is the primary driver of these land cover changes. Detecting land cover change is essential to determine the magnitude of the shifts occurring on the land surface. In practice, detection can be conducted through direct observation or by utilizing remote sensing. Remote sensing produces multitemporal imagery as a primary data source. This multitemporal imagery can be processed and analyzed using various methods to identify the changes that have occurred in land cover. With technological advancements, implementing machine learning for this task can help optimize resources for land cover change detection. Machine learning models built with the Random Forest algorithm yield accurate detection within the target areas. The Random Forest algorithm is an appropriate choice due to its capability to process complex and imbalanced data using decision tree methods. The model in this study achieved an accuracy of 0.9641, or 96.41%, with model evaluation performed using a confusion matrix. Land cover change detection using machine learning produces results with high accuracy. Consequently, policies regarding land cover change can be formulated by considering climate change mitigation and efforts to preserve the environment for the well-being of all living things
