| dc.description.abstract | The mangrove ecosystem as one of the coastal and marine ecosystems has great
potential for the welfare of the community in terms of economic, social, and
environmental aspects. The condition of the mangrove forest in Lubuk Kertang
Village is experiencing increasing damage. Expansion of oil palm plantations
makes fishing villages vulnerable to flooding, reduces the ability of mangroves to
store carbon for a better climate and increases sedimentation in the soil around the
waters of mangrove forest areas. Ecologically, the conversion has caused a decline
in the ecological function of the area. This study aims to determine the impact of
changes in the mangrove ecosystem on mangrove environmental services in terms
of mitigating climate change and preventing sedimentation using Landsat satellite
imagery in the mangrove forest of Lubuk Kertang, Langkat. This research was
conducted from December 2021 to August 2022. Changes in environmental services
were analyzed with changes in land cover using the supervised method and
followed by the Normalized Difference Vegetation Index (NDVI), Land Surface
Temperature (LST), Bare Soil Index (BSI), Total Suspended Solid (TSS) using
Landsat images 5, 7, and 8. The analysis was carried out in 2002-2020. The results
of the supervised analysis showed changes in mangrove forests where at first the
forest condition was good, then it was damaged, then recovered. This is supported
by the analysis of plant density/NDVI which increases, then decreases, then
increases again. The impact of these changes on environmental services is felt
directly by the surrounding community, even on climate change, one of which is
caused by an increase in carbon emissions
