Abstract

Catchment Area has a hydrological function for the sustainability of the PLTA Koto Panjang Reservoir. As the number and activity of the Koto Panjang catchment area population increases, it has experienced hydrological pressure and land degradation. The study was conducted to identify the condition of critical land in the Koto Panjang catchment area. The research was conducted in the water catchment area of PLTA Koto Panjang in June-August 2018 using an overlapping approach using Geographic Information System application. The analysis is done descriptively. The results showed that the area of 329,305 ha of Koto Panjang hydropower catchment area, 32.8% classified as critical, 42.3% classified as critical potential, 19.6% classified as rather critical, 1.1% classified as very critical, 0.3% classified as not critical 0.3%. The criteria for the condition of critical land in this catchment area can be used as a reference for determining the priority location for the management of the Koto Panjang Hydroelectric Reservoir.
