Analysis of Spatial distribution of Peatland Depth in Keub Village

Peat is an ecosystem that is formed due to biomass production that exceeds the decomposition process. The area of peat land in Aceh Province reaches 338,164 ha. Improper use of peatlands results in peatland degradation so that the thickness and depth of the peat soil decreases. This research aims to determine the map of changes in the distribution of peat depth classes and determine changes in the peat ecosystem classification map in Keub Village by comparing the peat depth map published by the Ministry of Environment and Forestry in 2019 with interpolation results using the inverse distance weight method. The results of this research showed that there was a change in the peat depth class and the area of distribution of the peat depth class between the peat depth class map published by the Ministry of Environment and Forestry and the interpolation results in Keub Village. Based on a comparison of the KLHK peat depth map with the interpolated map, it was also found that there was a change in the area of protected functional areas in the form of an increase in the number of areas.
