Abstract

The purpose of this study was to assess the coastline changes in north coast of
Semarang-Demak. The research method was used satellite image interpretation
of Landsat Image in 1998 and Allos Image in 2006, and field cross-checking. By
overlaying the two satellite images through a geographic information system to
determine the changes that can occured on the north coast of Semarang-Demak.
Based on research results showed that the accuracy obtained by 93% and could
be valid from 28 observation points that form the shoreline and land use.
Shoreline that occurred between 1999 and 2006 experienced more abrasion
process if compared with accretion. The Advice of this study was to accelerate
determination of the shoreline changes preferably used remote sensing images, in
order to involved community in preventing any abrasion. The methods could be
done through greening coastal areas, for example by mangroves planting on the
beach.
