Abstract

The research aims are to know the vegetation density level using vegetation index method of NDVI, SAVI, ARVI, DVI and RVI and to know the highest accuracy of vegetation index methods to determine the vegetation density in protected forest Mount Ungaran. The sampling method use purposive random sampling, with 82 sampel points. This research uses descrpitive research method. The first variable is vegetation density and the second ones is distribution and area produced by vegetation index transformations. The result of this research shows that the distribution and the area of classification results for each vegetation index transformation are different. There was little differenceof wide in the transformation of NDVI and SAVI is an area of 900 m2, equevalent to one pixel on the Landsat-8 imagery. Meanwhile classification generated by the transformation of ARVI, a lot of generating area is included dense classification, and the classification generated by the transformation of DVI and RVI is more a lot included rare classification. The confusion matrix shows NDVI transformation has the best accuracy with an overall accuracy percentage of 75,61%.

Abstract

This study aimed to find out the spatial impact of the establishment of temple industrial area on the land use in Ngaliyan. Quantitative approach with spatial data processing, weighting and descriptive methods was used in this research. The establishment of industrial areas would make either positive impacts or negativer ones; it would require certain amountof land, so that land – use changes occurred, guava orchards transformed into industrial area. By knowing this industrial area development, some impacts could be decreased and its RTRW system( administrative division) could be obeyed. The research results showed that the most significant land use in 2005 until 2015 was for industrial arears of 5.59 ha, and for the residential areas increased to 2.75 ha. As for the carrying capasity in Ngaliyan, it had a medium one so that it had a moderate interpretation as well; and the impacts of the land – use changes underwent some condition changes due to the development of industrial areas around the templen in the amount of -1,33 %.
