LEVEL OF MANGROVE DENSITY WITH USING NORMALIZED DIFFERENCE VEGETATION INDEX METHOD IN SORONG CITY AND ITS SURROUNDING AREA, WEST PAPUA PROVINCE OF INDONESIA

Abstract

The mangrove forest is a coastal ecosystem having high economic value for supporting fisheries activities. Monitoring to detect a change in mangrove condition has to be done continuously. One of way is the application of remote sensing technology with Citra Landsat 8 OLI which had been used in many types of research to monitor the condition of mangrove forest. This study was carried out to reveal changes in the density of mangrove vegetation in Sorong City. The method used was the Normalized Different Vegetation Index (NDVI) values with the measuring of mangrove vegetation started from 2012 to 2018 period. The result of this study was the high dense level was in increasing 568.08 ha, the medium dense level was in increasing 12.03 ha, and the low, dense level was in decreasing 153.09 ha. This showed that the high dense level was better than both the medium and the low level. According to KEPMLH No. 201 Year 2004 that condition of mangrove density level in Sorong City and its surrounding area, West Papua Province was included a good category.
