Abstract
The Sidutan and Reak Watersheds have 37.77 km2 and 23.66 km2 basin areas, both of which are still protected forests. Along with the increase in human activities, the community's raw water needs in both watersheds can also influence the magnitude of the infiltration rate and runoff, where infiltration and runoff coefficient will affect the River Regime Coefficient (RRC). River Regime Coefficient is the magnitude of the ratio between the maximum and minimum daily discharge in a year in the river. Whereas to get runoff coefficient every year a single hydrograph and rain per hour are needed in a year. The relationship between river regime coefficients and runoff coefficients can produce a correlation equation is a linear equation. In the analysis, the runoff coefficient value in the following year in each river channel is enough to replace the value of the river regime coefficient with a linear equation. The analysis shows that the value of the River Regime Coefficient (RRC) with Runoff Coefficient in the Sidutan Watershed yields the equation Y = -2E-05x2 + 0.0048x -0.0539 with a coefficient of determination R2 = 0.6796. River Regime Coefficient (RRC) values obtained from 2011 to 2016 were 67.69; 43.99; 188.92; 53.78; 45.01 where the value is included in the low and too high classification range. The results of the analysis indicate the watershed is in bad condition. From the analysis of runoff coefficient (C) each watershed is 0.188; 0.101; 0.229; 0.163; 0.148, shows that the level of runoff coefficient (C) of the watershed is still in good condition. From the results of the analysis of the River Regime for the Reak River Basin, the equation Y = 0.0003x2 - 0.011x + 0.1618 with a coefficient of determination R2 = 0.7855. Where the RRC Value obtained in 2011 until 2016 respectively 27.46; 29.80; 31.06; 16.96; 14,11. The results of the analysis are included in the very low classification range and to a low degree. From the results of the analysis, the Reak River Basin is still in good condition.
