There were two methods as well as direct and indirect. Direct analysis was intended to see degradation level of mangrove forest based on analysis in the field and then analyzed again the degradation rate, which refered to the Decree of the Minister of Environment of Indonesia, Number 201/2004 on the Criteria and Guidelines for Determining Damage of Mangrove Forests. The indirect method was to perform the analysis of degradation level of mangrove forests based on NDVI (Normalized Difference Vegetation Index) using Landsat 8 satellite image. This research was expected to give figures of the current mangrove forest in Percut Sei Tuan District and the degradation level. The results showed that mangrove forest in Percut Sei Tuan District in damage category with 4.161% of crown closure and there was 168.7 ha in damage category based on NDVI value.Keywords : mangrove degradation level, NDVI, standard criteria, Percut Sei Tuan
