Abstract

Kota Gresik merupaka daerah dengan banyak lahan
kosong yang potensial untuk didirikan perumahan. Ada banyak
pengembang kawasan di daerah Gresik salah satunya adalah
Perumahan Kepatihan yang terletak di Kecamatan Menganti.
Sering terjadi banjir di Kota Gresik setiap tahun pada saat musim
hujan termasuk Kecamatan Menganti salah satunya. Oleh karena
itu perlu adanya perencanaan sistem drainase untuk kawasan
perumahan Kepatihan agar tidak terjadi Banjir
Dalam perencanaan sistem drainase, perlu dilakukan
beberapa analisis. Data-data yang dikumpulkan meliputi data
hidrologi, data peta dan data hidrolika. Data hidrologi berupa
data curah hujan dan jumlah stasiun hujan yang berpengaruh.
Data peta berupa topografi dan site plan. Data hidrolika berupa
koefisien pengaliran. Setelah data terkumpul dilakukan analisis
hidrologi digunakan untuk mencari debit banjir rencana
selanjutnya dilakukan analisis hidrolika digunakan untuk mencari
dimensi saluran dan kebutuhan kolam tampung.
Berdasarkan hasil analisis yang dilakukan, didapatkan
curah hujan rencana periode ulang 5 dan 20 tahun masing-masing
ii
108,97 mm dan 126,63 mm. Dimensi saluran bermacam-macam
dengan minimum ukuran 30x30 cm hingga maksimum 100x100 cm.
Kolam tampung direncakan dengan total volume 13.955,4 m³
====================================================================================================================
The city of Gresik is an area with a lot of vacant land that
has the potential to build residential. There are many developers
in the Gresik, one of which is the Kepatihan Residential which is
located in Menganti District. Floods often occur in Gresik City
every year during the rainy season, including Menganti District,
one of them. Therefore, it is necessary to plan a drainage system
for the Kepatihan housing area so that flooding does not occur.
In planning the drainage system, it is necessary to do some
analysis. The data collected includes hydrological data, map data
and hydraulics data. Hydrological data in the form of rainfall data
and the number of influential rain stations. Map data in the form
of topography and site plan. The hydraulic data is in the form of
flow coefficient. After the data is collected, a hydrological analysis
is used to find the planned flood discharge, then a hydraulic
analysis is used to find the dimensions of the channel and the need
for the reservoir.
Based on the results of the analysis, it was found that the
planned rainfall for the 5 and 20 year return periods was 108.97
mm and 126.63 mm, respectively. Channel dimensions vary with a
iv
minimum size of 30x30 cm to a maximum of 100x100 cm. The
reservoir is planned with a total volume of 13,955.4 m³
