Abstract
Jakarta got its water from Mt. Salak in Bogor, land it is not directly adjacent. From Mt. Salak to Jakarta, the water has to pass a few other regencies like Bogor, Depok, and South Tangerang. That means whatever changes happen in those areas will affect how the water reaches Jakarta. Therefore, a system is needed to track how the land changes in those areas, and one of them is through satellite images, Landsat 8. The images taken will give a rough visual of the land, but as data, it has to be in numbers. A method called Gradient Boosting Regression helped with that. This method can build a model that classifies every pixel of the images and, in this research, green, partial green, and impervious. This model has an accuracy of 99.3349% for the training data and 99.1658% for the validation data and took 13.91376 seconds to complete. From this model, there is a trend where the green area keeps decreasing through the years, and the district with the highest area of land-use change from green to impervious is Sukamakmur in Bogor.
