ABSTRACT: Forest encroachment
and both of its complexity and implication is a problem that faced not only an
area/region but also all forest areas in the country, so that the encroachment has been a national
scale problem that supposed to have serious attention especially to overcome it. Natural disaster
such as flood, landslide that always happened in rainy season and often cause
hundreds of unguilty victim. The research was to find out the result of
interpretation and the width of protected forest encroachment, South Dolo
Subdistrict Sigi Dictrict. The research applied supervised classification and
NDVI (Normalized Difference Vegetation Index) analysis. The analysis used in
the research was managing image digitally that used for image correcting, image
band compositing, image cutting, image sharpening and clarifying. Based on the
research it was found that the clarification result of land covering consisted
of primary forest, secondary forest, opened lang, plantation and settlement.
The map of land covering for the research had the accuracy level of 86%, meant
that the map for the research fulfilled the standart of carefulness
interpretation and very good for seeing the class of land covering type in
protected forest of South Dolo
Subdistrict Sigi District. The area of Protected Forest in South Dolo
Subdistrict had density level with interval vegetation Index (NDVI) from -0,58
to 0.07 with 966,50 width or 100 %
percentage. The result of scoring count showed that the result of NDVI with
rare criteria was -0,58- 0,07 and the land use that consisted of forest with
width of 26.947,79 ha (93,04 %) and
encroachment rate of 180 and in the category of fair encroachment level, good
managed land in width of 3.92,99 ha (1,35%)
encroachment rate 240 with high encroachment level, and bad managed land
with widht of 1.625,72ha (5,61 %) and
encroachment rate of 300 was in the level of high encroachment, therefore the
total width was 28.966,50 ha (100%).
