Kajian Penerapan Model Soil and Water Assesment Tool (SWAT) Untuk Pengelolaan Sub DAS Tapung Kiri

---

Some watershed management activities carried out in upstream areas such
as land management activities that encourage erosion, in turn will have an impact
in downstream areas. The Tapung Kiri Sub-watershed is a sub-watershed of the
Siak watershed located in the upstream part of which is a buffer zone for the
central and downstream areas of the Siak watershed. This study aims to establish
scenarios for improving water management and sedimentation in Tapung Kiri
Sub-watershed.
In this study, the simulation used Soil and Water Assesment Tool (SWAT)
model. To assess the predictive power of the hydrological model the Nash-
Sutcliffe efficiency coefficient (NSE) is used. To see the accuracy of the model
output patterns with the results of field observations used deterministic coefficient
(R2). The model has a good performance in predicting river water discharge, in
the calibration process the model shows an R2 of 0.63 and an NSE of 0.62 while
the model validation process shows an R2 of 0.76 and an NSE of 0.71. In the use
of the SWAT model the user can conduct land use management simulations,
namely by first making a land use change scenario. In this research, three
scenarios of land use patterns in Tapung Kiri Sub-watershed are used. Scenario I
uses land use patterns according to the spatial pattern of Riau Province RTRW.
Scenario II uses land use patterns according to the Spatial Plan pattern of Riau
Province RTRW but on agricultural land is modified to agroforestry. Scenario III
uses land use patterns according to the Spatial Plan pattern of Riau Province
RTRW but on plantation land it is modified to become agroforestry.
The best recommendation is scenario III, in addition to be able to reduce
surface flow, it is also able to significantly increase base flow. It also means that
by modifying plantation land into agroforestry in the spatial plan, besides being
able to reduce the risk of flooding it also has a significant effect on increasing
water availability in the dry season. Scenarios I, II, III have a significant
influence on the decline in sedimentation results in the Tapung Kiri Subwatershed
compared to the existing conditions in 2018. The best recommendation
is also in the condition of scenario III.
