Monitoring Tingkat Kekritisan Lahan Menggunakan Citra Sentinel 2a Di Kecamatan Banyakan, Kabupaten Kediri

Monitoring the Criticality Levels of Land Using Sentinel 2A Imagery in Banyakan Subdistrict, Kediri Regency

Abstrak

Banyakan Subdistrict, Kediri Regency, is experiencing pressure from the conversion of agricultural land into intensive infrastructure development, which potentially leads to land degradation. This study aims to analyze land cover and monitor land criticality levels in Banyakan Subdistrict for the years 2017 and 2024 using Sentinel-2A imagery. Land cover classification were analyzed using the maximum likelihood classification method. Land criticality was assessed by five parameters: land cover, slope gradient, erosion hazard level, land productivity, and land management. The results show that mixed gardens dominate the land cover classes. There was an increase of 97.22 hectares in open land, mainly due to airport construction. The largest increase in the potentially critical land class occurred in agricultural areas, reaching 466.91 hectares, accompanied by a reduction of 832.73 hectares in the moderately critical land class. These changes indicate that although some land conditions have improved, active land degradation is still ongoing.
