- Land cover and vegetation density are important information needed in watershed management activities (planning, utilization, supervision and control). Remote sensing technology has been widely used to produce information on land cover and vegetation density due to the availability of multitemporal, multispectral data with high spatial resolution. The purpose of this research is to determine land cover and vegetation density using sentinel 2A imagery in the Salubi sub-watershed. The research was conducted in the Salubi sub-watershed, Central Sulawesi Province. Research activities include digital image analysis using unsupervised classification techniques and NDVI (Normalized Vegetation Index), field measurements and accuracy tests (confussion matriks). The results show that the land cover consisted of 45.61% forest (643.09 Ha), 36.66% (516.81 Ha) mixed dryland agriculture, 10.72% paddy fields (151.11 Ha), shrubs 2.8 % (36.41 Ha), water bodies 1.62% (22.84 Ha), bare land 0.99 % (13.95 Ha), settlement 0.98 % (13.87 Ha), grassland 0.84 % (11.79 Ha), with an accuracy of 90 % (overall accuracy) and 89.54 % (kappa accuracy). Vegetation density consists of high 79.48% (1,120.61 Ha), medium 15.52% (218.86 Ha), low 4.15% (58.53 Ha), non-vegetation 0.84% (11.87 Ha)
