PERENCANAAN REHABILITASI KOLAM DETENSI MELATI JAKARTA PUSAT
ABSTRACT: Drainage system with
polder and pump is the most effective and efficient system for handling the
floods that was occurred in the area which has a slooping topography such as
Jakarta. As the state’s capital and metropolitan city, Jakarta has been developing
rapidly, which made the existing green land as water infiltration area and
settlement become unbalanced. This is a
major cause of flooding in Jakarta. From the result of rainfall data
processing in Kemayoran station, rainfall intensity can be analyzed by using
Jakarta’s hyetograph diagram approach for Ciliwung’s watershed based on
analysis that was conducted by Netherland Engineering Consultant. Qplan is
obtained by modeling it with additional program, the SWMM 5.0 for a period of
100 years, due to Jakarta as a business and government center. Large catchment
area and downtown are the reason that SWMM 5.0 is suitable to use for modeling.
Thus Qplan is obtained in the amount of 11 m3. Reservoir’s volume in the amount
of 75888 m3 is obtained by using Qplan, at the existing condition detention
pond area is 49000 m2, so depth of pond is 5 m with 8 pumps and 4 m3/sec
capacity is obtained.
