A Watershed is an ecosystem whose first component consists of natural resources vegetation, land, water, and human resources. Tabunio watershed covering an area of 62,558.56 hectares consists of 10 sub-watersheds. The Normalized Difference Vegetation Index (NDVI) is used in vegetation density analysis. Vulnerability of environmental damage is the condition of a region that has the potential for environmental damage due to human activities and or activities that have the potential to cause environmental impacts.The purpose of vegetation density analysis is carried out for the evaluation of environmental vulnerability dynamics in Tabunio watershed, i.e: 1). Knowing changes in land cover; 2. Knowing the classification of vegetation density; 3. Determine efforts to increase vegetation density. The benefits of this analysis are to obtain directives that can have a positive impact on the control of flood suppliers' vulnerability and environmental vulnerability by determining forest and land rehabilitation techniques.Based on the results of mapping and analysis obtained: 1) changes in land cover in 2005-2020 are dominant in forest land cover, open land, settlements, plantations, swamp farming, shrubs, and mining; 2) Vegetation density in the upstream sub-watershed is dominated by the classification of dense and very tight vegetation density; 3) The green revolution of the upstream watershed is dominated for ecological purposes with dense and very close vegetation, the central part of the watershed is dominated for ecological, economic and social with tight vegetation, downstream green revolution watershed dominated for economic and social interests with dense and sparse vegetation

The research location is in Asam-Asam PT Arutmin Indonesia, located in District Jorong, Tanah Laut, Kalimantan Selatan. This study aims to determine the relationship of visual rock with PAF and NAF rock properties based on the distribution pattern, volume, and utilization. Visual identification that shows the strong correlation of PAF on the grain size of silt, color dark gray lithology, and lithologic silt. a strong correlation was also found on NAF rock with a grain size of clay, fine sand, very fine sand. In the color white rock medium, medium gray, light gray. obtained a volume of PAF: 208 309 329 BCM, NAF = 200 764 182 BCM volume, so the volume of NAF to be taken can coat 3,5 meters disposal.
