Abstract

Abstract
Mangrove forests are one of the coastal ecosystems that have significant ecological and
economical value. This ecosystem is known for its role in protecting coastal environment
against waves and storms as well as supporting the life of numerous marine organisms.
However, the increase of human population and the need to expand settlements and industrial
areas makes many mangrove ecosystems vulnerable. Objectives of this research were to
measure the change of mangrove’s area of Sidoarjo district using satellite imagery data
from different period and to classify the area based on their vegetation density. To measure
the density of mangrove vegetation NDVI index were employed. Results of Landsat ETM-7
(acquisition 2002) and ALOS (acquisition 2010) analysis showed that mangrove’s area of
Sidoarjo district has declined intensively. Illegal logging and land use changing were
suggested to be the main cause of the destruction of mangrove forest in this area. In order to
prevent further destruction of the mangrove’s area, local authorities have implemented UU
No.27 where heavy penalties are implied for illegal logging.
