This study aims to find out how changes in mangrove forest area and how the density of mangrove forests in Panikiang Island changes from 1998 to 2018. Analysis of changes used is the analysis of remote sensing images. The image used is satellite imagery LANDSAT 5 TM acquisition 1998 and LANDSAT OIL imagery acquisition in 2018. The guided classification method with the maximum like-lihood method is used to determine changes in mangrove forest area, while for non-guided classification using NDVI formula. The results obtained in 1998 mangrove vegetation covering an area of 6.93 hectares experienced changes in land cover to non-vegetative mangrove and elsewhere on the island became 3.24 hectares of mangrove vegetation. Changes in the area of mangrove forests from 1998-2018 were 3.92 hectares.The density of the Pannikiang Island mangrove forest in 1998 with the class of meetings decreased by 34.56 hectares, the density class increased by 23.67 hectares and the density rarely increased by 7.2 hectares.
