Problems that often occur in the Koto Panjang Hydroelectric Reservoir in generating electricity are, fluctuations in water flow between the dry season and the rainy season which affect the water level of the reservoir. Within 8 years the land cover undergoes major changes, where the extent of open land or deforestation can accelerate the inflow into the reservoir and have an impact on the high level of erosion which subsequently causes siltation which can reduce the volume of reservoirs. The research objectives are to; analyze the magnitude of changes in land use from various types of land cover in different time frames, index of land cover by vegetation along with the suitability of actual land use for the Regional Spatial Plan (RTRW), analyze the influence of hydrological characteristics of land use changes using the SWAT model, analyze the magnitude pressure and value of population dependence on agricultural land, and get a suitable land use model to be developed in maintaining sustainable water availability. Land use changes that occur from land cover in the Koto Panjang Hydroelectric Reservoir in the period between 2011 and 2014 is a decrease in the area of primary and secondary dryland forests which has decreased, resulting in an increase in the type of non-forest use. The vegetation cover index (IPL) in 2011 and 2014 shows that the quality of the vegetation is in good condition, the suitability of land use (MPA) for regional functions is classified as moderate. The simulations on existing land use in 2011 and 2014 with rainfall (PREC) produce WYLD, the value of C and the value of KRS are still classified as good. In the condition of land use in 2014 (existing) with the existing PREC produced WYLD, the value of C, and the value of KRS was also still classified as a good classification. Population pressure (TP) on agricultural land in general is still classified as good because TP 1. Application of the best land use model (scenario III) with PREC in 2014 producing WYLD, C value, and KRS value better than existing land use (2014), land use that is best applied to agricultural cultivation areas is simple and complex agroforestry patterns simultaneously with the development of low fill species among tall plants. Land optimization with a linear Quantitative Methods (QM) program for Windows 4 produces coffee infill types in simple agroforestry patterns and gambier for complex agroforestry patterns that can increase the social and economic value of the community.

Keywords: SWAT Model, Agroforestry, Quantitative methods, Land optimization.
