Using Sentinel image to study land cover change from 2015 to 2019 in Probolinggo and Pasuruan regencies

Land Use Land Cover (LULC) changes represent human influences on the natural ecosystem. The LULC change can potentially propagate severe hydro-meteorological disasters (such as landslides, floods, or drought). This study aims to analyse such changes in the Pasuruan and Probololinggo Regency in East Java, a region of ±3320.3 km2. The changes are analysed by comparing two maps derived from Sentinel-2 Images. Three subsets are explored to understand the LULC changes. Regional development from 2015 to 2019 has increased built-up areas by 97.03% (171.43 km2) and forest plantation areas by 294.09% (658.75 km2). Conversely, the development has reduced paddy fields by 58.25% (443.98 km2) and water bodies by 17.60% (0.45 km2).
