The results of the research stated the total carrying capacity value of Sub watershed Batang Kumu is 117.5. The condition of support capacity of Sub watershed Batang Kumu Sub-District Rambah Hilir Rokan Hulu regency is in the category of bad or in other words Sub watershed Batang Kumu that deserves to maintain its supporting capacity where socioeconomic and institutional assets / value and investment of buildings function as they should. While land conditions, water systems and regional development policies are performance parameters of Sub watershed Batang Kumu which has an influence in increasing the risk of ineligion to the sustainability of watershed ecosystems especially the percentage of critical land, the percentage of vegetation closures and erosion index that shows a very high classification level followed by sub criteria of flooding with high classification and protected areas with very poor classification
