THE CHANGE OF MANGROVE COVERAGE IN SEGARA ANAKAN LAGOON OF CILACAP – CENTRAL JAVA
Abstract: Mangrove ecosystem
play san important role in coastal area. In several region mangrove coverage
had decreased caused by various factors such as landuse change, erosion and
sedimentation. Mangrove ecosystem in Segara Anakan Lagoon had decreased and
damaged as well. The current work aimed to analyze the change of mangrove
coverage in Segara Anakan Lagoon. A remote sensing analysis was conducted to
deployeight years of satellite imagery data from 2002 to 2009. Analysis method
included NDVI algorythm map processing which was associated with vegetation
coverage in the area of interest. The results show that mangrove coverage in
Segara Anakan Lagoon had decreased from 9,163.19 ha in 2002 to 8,433 ha in
2003, 7,764 ha in 2004, 7,252.72 ha in 2005 and 6,213.80 ha in 2006
respectvely. Further decrease occured in 2007 to 5,767.16 ha, 4,987 ha in 2008
and finally to 4,267.13 ha in 2009. Mangrove coverage is decreased
approximately 677 ha each year. This decrease might be caused by several
factors such as conversion of mangrove coverage to other utilization such as
farming, housing and ponds, and high sedimentation rate from Citanduy river.
These results suggest that management of mangrove area is needed to support
coastal resources sustainability in Cilacap. Therefore, replantation and conservation
of mangrove area could be applied for management purposes.
