Environmental management efforts due to landslides in Lunyuk Rea Sumbawa

Abstract

Indonesia is located in the movement of tectonic plates that collide with each other, namely the Eurasian plate, the Pacific plate, and the India-Australia plate, causing many changes in geological configurations that can cause disasters. Landslide disaster often occur in Lunyuk Rea Village which causes a decrease in environmental quality. This study aims to determine how the environmental management efforts due to landslides for environmental preservation. This study uses a survey method with a quantitative analysis approach based on topographic conditions in the field, spatial identification using remote sensing imagery, and digital elevation models as well as qualitative analysis by dividing land use classification, rock types, soil types, rainfall intensity. The results of the analysis of the level of environmental damage in Lunyuk Rea Village are included in the moderately damaged and heavily damaged categories. The environmental management strategy in Lunyuk Rea Village is to apply vegetative, mechanical, chemical, and normative methods.
