Abstract
The era of regional autonomy has triggered the development of Dumai City towards a better
direction. As a coastal area in Riau Province, it is estimated that it will threaten one of the
potential coastal ecosystems, Dumai City is a mangrove forest. This study aims to analyze
deforestation of mangrove ecosystems in Dumai City, Riau. Analysis of deforestation using ArcGIS
and NDVI clasic version 4.5 software for imagery in 2005, 2010 and 2015. The causes of
deforestation were carried out through interviews with the community.
In 2005 there was 649.64 ha of mangrove area, but 46.79% of deforestation had occurred in the
Dumai City mangrove forest so that in 2010 the remaining area was 345.06 ha. The main factors
driving the deforestation of mangrove forests in Dumai City stem from the conversion of land into
industrial estates, the construction of ports, roads, plantations, agriculture, and settlements. In
addition, it is also caused by the use of mangrove wood for household needs, charcoal wood and
building materials. The utilization of mangrove wood can be proven from the magnitude of the
percentage of logged-over stumps which is more dominant (amounting to 67.32%) compared to
natural dead stumps
