Abstract

Natar District is one of the districts in South Lampung Regency which has an area of 213.77 km2 or around 21,377 HA. In the agricultural sector, most of the land in Natar District is dominated by maize and paddy fields. This study aims to determine changes in land use in 2002, 2009 and 2019 in Natar District, South Lampung Regency. This study uses imagery from Landsat 7 and 8 processed in the NDVI (Normalized Difference Vegetation Index) method with the formula "NDVI = (NIR-RED) / (NIR + RED)". After processing the data, field observations were made to 30 sample points which were spread evenly throughout the Natar District. In this study, the results showed that land conversion to open land increased every year, on the other hand the area of land with low to moderate vegetation density decreased every year. In field observations, it was found that various land uses ranging from settlements, markets, and various uses for agricultural and plantation land. Open land in Natar District in 2019 increased by 32.7% from 2002, on the other hand, low and moderate vegetation land has decreased by 32.5% and 12.5% respectively since 2002. The government must tighten environmental regulations regarding land which can be converted or not. If population growth becomes uncontrolled, the conversion of agricultural land functions increases, it will be impossible for Indonesia to realize national food security
