Abstract :
The research focuses on the effect of land use
changes on water availability as an effort to conserve
water resources in the Upper Brantas watershed. The
purpose to be achieved by the author include analyzing
the condition of land use changes to the forest area,
analyzing the availability (discharge) of water, and how to
conserve land in the Upper Branras watershed with a
social and community approach, so as to added the
economic value. While the limitations in this study are
limited to the scope of the upstream Brantas watershed
up to the Sengguruh Dam, which has a sub-watershed
system including the Sumber Brantas Sub-watershed,
Bango Sub-watershed, Amprong Sub-watershed, and
Upper Brantas Sub-watershed. The analytical method is
the mainstay discharge calculation using the Mock
method while land use changes are processed with the
help of ArcGIS software. From the results of this study it
was found that there was a change in land use from 2017
to 2019 where secondary dry land forest decreased by
1,357.27 ha, while industrial plantation forests decreased
by 465.79 ha, a significant addition occurred in the use of
paddy fields, namely area of 4,319.19 ha. From the results
of the hydrological analysis, it was found that the
availability of water (effective discharge) had a
downward trend where in 2017 it was 9.92 m3/s while in
2019 it was 6.70 m3/s. From this it can be concluded that
changes in land use in 2017-2019 have an impact on the
response of the upstream Brantas watershed which can
be seen in the decrease in effective discharge in the same
year. Therefore, this needs to be a special concern for the
government and stakeholders in the Upper Brantas
watershed area to take conservation actions so that they
can maintain and even improve the quality of the area. In
carrying out the conservation of the Brantas watershed
area, it is necessary to increase the awareness of the
surrounding community to participate in maintaining the
quality of the environment in this area, where by
implementing the concept of environmental conservation
programs that can improve the community's economy
either through the agricultural or plantation sectors as
well as from other sectors. Where the program with the
concept of the community for the Upper Brantas
watershed is expected to be able to create good and
sustainable environmental conservation.
