Analysis Land Use Changes In Mila Dam Using Software Arcswat

Mila Dam is a multifunctional dam to support the continuation of the 1,689 hectare Rababaka Komplek Irrigation Area (DI) in Woja District which supports the irrigation rababaka complex. The Rababaka Complex irrigation system is the first interconnection irrigation system in Sumbawa Island. Land use changes that occur in the Mila Dam catchment (DTA) obtained from the comparison of 2013 satellite imagery with 2018. In 2013 the available open land area was 15% or 273.4 Ha, while in 2018 the land area existing open land is 51% or 927.6 Ha. With the change in the area of open land in the Mila Dam catchment, of course this will affect the amount of land erosion that occurs and the amount of sedimentation entering the Mila Dam. The highest level of erosion hazard (TBE) in 2013 in the Mila Dam watershed is the level of Light with an area of 1230.95 ha or 77.99% of the total area, followed by medium TBE class with 250.12 ha or 15.85% of the watershed area. The highest level of Erosion Danger in 2018 in the Mila Dam watershed is the Medium level with an area of 724.74 ha or 45.92% of the total area, followed by the Lightweight TBE class with 546.33 ha or 34.61% of the watershed area. From the simulation results that have been modified in the sub-watershed with very severe and severe TBE, it can be seen that there was a change in Heavy Erosion Danger (TBE), which initially was 16.28% to 1.19% and the sediment transport yield decreased from 3048.85 tons / ha / year to 2517.58 ton / ha / year. From the simulation results that have been modified on sub-watershed with TBE Very Heavy, Heavy and Medium. It can be seen that there was a change in Heavy Erosion Hazard Level (TBE), which was originally at 16.28% to 0.65% and the results of sediment transport which declined from 3048.85 tons / ha / year to 1692.98 tons / ha / year. The following is a map of the Mila Dam Erosion Danger Level with the modified 2018 land Use conditions.
