ANALISIS PERUBAHAN TUTUPAN LAHAN DI KAWASAN HUTAN PRODUKSI TERBATAS KECAMATAN OGODEIDE KABUPATEN TOLITOLI

Abstract

The evolution of changes in a region's land coverage can be analyzed using remote sensing data from
multitemporal satellite images. One method for promptly determining the conversion of land function
is using remote sensing technology. The coverage of forest land varies from year to year due to
biophysical elements in forests and human activities. The purpose of this research is to discover and
observe changing of land coverage in Ogodeide district at limited forest production region over the
period of 5 years from 2017 to 2022. The research was carried out over a three-month period, from
October to December 2022. The research was conducted in the limited forest production area at
Ogodeide district, Tolitoli regency, utilizing the supervised classification method (Supervised
Classification), a field survey, and accuracy testing with field data. The classification result of Landsat
8 year 2017 image in the limited forest production region yielded a total area of 713,71 ha and consisted
of four land coverage classes, namely, forests (239,05 ha), open land (159,93 ha), plantations (194,61
ha), and shrubs (120,12 ha). In 2022, a total area of 713,71 ha was gained, with each area encompassing
180,75 ha of forest, 170,24 ha of open land, 304,41 ha of plantations, and 58,32 ha of shrubs. Based
on the results, it can be concluded that all land coverage classifications have changed from 2017 to
2022. The forest's land coverage has decreased by 58,3 hectares. The amount of open land has increased
by 10.31 hectares. With an area of 109.8 ha, the plantation's land cover has been expanded. In addition,
bush land coverage has been reduced by 61.8 ha. The accuracy and thoroughness level of the image
management outcomes of the supervised classification approach reached 92.18% for the accuracy test
results.
