Abstract
Permasalahan banjir merupakan salah satu permasalahan umum
yang sering terjadi di sebagian wilayah Indonesia, misalnya di
PT.HANIL JAYA STEEL. Perkembangan industri baja terjadi
karena adanya kebutuhan konsumsi baja fabrikasi yang pesat,
yang membutuhkan berbagai infrastruktur baru seperti
pengaturan drainase dan lain-lain. Lahan yang semula rendah dan
kosong ditimbun untuk dibangun berbagai infrastruktur dan
kawasan PT.HANIL JAYA STEEL menjadi semakin
berkembang. Perkembangan PT.HANIL JAYA STEEL ternyata
diikuti oleh munculnya genangan banjir dibeberapa tempat, hal
ini terjadi karena perkembangan kawasan tidak diikuti oleh
pembangunan sistem drainase nya yang memadai. Saluran
drainase yang kurang memenuhi syarat sehingga pada saat elevasi
air Sungai yang berada disekitar kawasan pabrik tidak dapat
berfungsi lagi. Akibatnya setiap musim hujan PT.HANIL JAYA
STEEL selalu tergenang banjir. Untuk mengatasi genangan banjir
penampang saluran pada sistem drainase PT.HANIL JAYA
STEEL harus diredimensi.
Untuk menormalisasi jaringan saluran drainase telah dihitung
Kapasitas maksimum saluran (Full bank capacity), dan debit
banjir rencana. Saluran drainase tersier direncanakan dengan
debit banjir periode ulang 2 tahun, saluran sekunder dengan periode ulang 5 tahun dan saluran drainase primer direncanakan
dengan debit banjir periode ulang 10 tahun.
Perbandingan antara besarnya kapasitas maksimum saluran
dengan debit banjir rencana, menunjukkan bahwa sistem drainase
PT.HANIL JAYA STEEL terjadi luapan banjir. Hal ini
menunjukkan bahwa sebagian besar penampang saluran eksisting
terlalu kecil sehingga harus diredimensi berdasarkan debit banjir
rencana. Untuk merencanakan dimensi saluran menggunakan
rumus Manning.
Selain itu, penanggulangan banjir harus dilakukan secara
komprehensif dengan mempertimbangkan beberapa studi
kelayakan seperti aspek teknis, sosial, ekonomi, hukum,
kelembagaan dan lingkungan. Oleh karena itu, kerjasama dan
perencanaan penanggulangan banjir PT.HANIL JAYA STEEL
sangat di perlukan dalam penanggulangan banjir dengan cara redimensi
saluran eksisting

The problem of flooding is one of the common problems that
often occur in parts of Indonesia, such as in PT.HANIL JAYA
STEEL. The development of the steel industry occurs because of
the need for rapid fabrication of steel consumption, which
requires a variety of new infrastructure such as drainage
arrangements and others. The land which was originally low and
empty stockpiled for built infrastructure and neighborhood JAYA
STEEL PT.HANIL be growing. PT.HANIL development JAYA
STEEL turns followed by the rise of floodwaters in some places,
this is because the development of the region is not followed by
the construction of its adequate drainage system. Drainage less
qualified so that when the river water elevation is around the area
of the factory can not work anymore. As a result, every rainy
season PT.HANIL JAYA STEEL always flooded. To cope with
the floodwaters cross section of the channels on the drainage
system must diredimensi PT.HANIL JAYA STEEL.
To normalize the drainage channel network has calculated the
maximum capacity of the channel (Full bank capacity), and the
flood discharge plan. Tertiary drainage channels planned to
discharge flood return period of 2 years, the secondary channel
with a return period of 5 years and the primary drainage channel is planned to discharge flood return period of 10 years.
The comparison between the magnitude of the maximum capacity
of the channel with the flood discharge plan, shows that the
drainage system PT.HANIL JAYA STEEL outburst flood occurs.
This indicates that most of the existing channel cross section is
too small and should be diredimensi by flood discharge plan. To
plan the dimensions of the channel using the formula of Manning.
In addition, flood prevention should be done in a comprehensive
manner by considering several feasibility studies as technical
aspects, social, economic, legal, institutional and environmental.
Therefore, cooperation and planning for flood prevention
PT.HANIL JAYA STEEL is in need in flood prevention by way
of re-dimension the existing channel
