| Summary: | Merapi eruption disaster in 2012 is the biggest eruption during the last 100 years.
Natural phenomena caused the significant landuse changing around Yogyakarta and Jateng.
The landuse changing post merapi eruption should be identified. To analyze the changing,
landsat 7 ETM+ imagery can be used.The landuse changing post 2010 merapi eruption can
be identified by using Landsat 7 ETM+ mode SLC-off.
Landsat 7 ETM+ mode SLC-off with path 120 and row 65 year 2009 and 2012 are
involved in this research. Broken sensor which cause the Remote Sensing Imagery that
produced by Landsat 7 ETM+ satellite is resolved with gapfilling process. By doing this, the
information contained in the image can be extracted. Through the imagery pre-processing
completed with gapfilling, image compossit, radiometric correction, geometric correction,
and imagery cropping, this research project is done. There were several stages to process.
These were the stages: choosing the training area, statistic calculating for the training area,
and detecting the changes.
This project using minimun distance digital classification. Overall accuracy for
Landsat 7 ETM+ year 2009 image is 88,9% and for year 2012 image is 89,6%. Change
detection analisys is proved that there are landuse changing on 2208,463 kms project area.
Urban area is increasing 70,124 kms, agriculture field is increasing 481,930 kms, water
landuse is increasing 23,292 kms, the width of volcanic material is decreasing 6,276 kms,
forest is decreasing 199,856 kms, farm is decreasing 82,905 kms, sand area is decreasing
27,736 kms, road is decreasing 1,776 kms, and for open area is decreasing 268,148 kms.
