Penelitian ini membahas penggunaan citra satelit Landsat 5 multispektral untuk menganalisis perubahan lahan akibat kejadian longsor di Paya Ateuk Aceh Selatan pada Mei 2008. Citra satelit yang digunakan adalah citra perekaman tahun 2007 dan 2009. Analisis dilakukan dengan menggunakan metode Change Vector Analisis (CVA) dan image differencing dengan analisis komponen utama kehijauan, kecerahan, kebasahan dan komponen indeks vegetasi Normalized Diference Vegetation Indeks (NDVI), Bare Soil Indeks (BI) dan Normalized Diference Water Indeks (NDWI). Aplikasi kedua metode tersebut mampu mendeteksi perubahan lahan akibat longsor di Paya Ateuk Aceh Selatan. Metode CVA mampu melakukan stratifikasi berbagai jenis perubahan tutupan lahan akibat tanah longsor. Dengan menggunakan klasifikasi multispektral komponen NDVI, dapat diketahui daerah yang mengalami perubahan lahan menjadi lahan terbuka akibat longsor tahun 2008 di lokasi penelitian.

Satellite image used in this study were recorded in 2007 and 2009. The analysis use Change Vector Analysis (CVA) and image differencing methods. The image differencing method using data extracted by principal component analysis greenness, brightness, wetness and vegetation index component Normalized Difference Vegetation Index (NDVI), Bare Soil Index (BI) and Normalized Difference Water Index (NDWI). The two method is able to detect labd cover changes due to the landslide in Paya Ateuk South Aceh. CVA method is able to stratify the different types of land cover changes due to landslide. By using multispectral classification NDVI component, it can be seen the area that changed into open land due to landslide in 2008 in the study area.
