Abstract
Menurut masterplan Kampus Institut Teknologi Sepuluh
Nopember (ITS) akan memiliki jumlah civitas akademik 25.000
orang dengan kebutuhan air minum sebesar 17 l/detik, sedangkan
tinggi hujan rata-rata di wilayah Kampus ITS seluas 187 ha
tersebut adalah 2.065 mm per tahun. Dengan demikian Kampus
ITS memiliki potensi dalam pemanfaatan air hujan untuk
memenuhi kebutuhan air minum. Dalam rangka pemenuhan
kebutuhan air minum secara mandiri dan mengurangi anggaran
biaya penyediaan air minum maka diperlukan perencanaan unit
bangunan pengolahan air minum Kampus ITS. Aspek yang ditinjau
dalam perencanaan ini adalah aspek teknis dan finansial.
Berdasarkan penelitian pendahuluan didapatkan air baku
yang berasal dari limpasan air hujan memenuhi standar kualitas air
baku kelas 2. Lokasi IPAM direncanakan berada pada lahan
seluas 1.927 m2 di Jalan Teknik Mesin Kampus ITS dan akan
dibangun 3 unit IPAM di lokasi tersebut. Sedangkan lokasi kolam
penampungan air baku memiliki luas 4.458 m2 dengan kedalaman
4-5 m yang berada 442 m dari lokasi IPAM. Pemanfaatan kolam
penampungan air hanya sebesar 50% dari kapasitas yang dapat
ditampung. Hal ini dikarenakan kolam penampungan juga di
manfaatkan sebagai tempat wisata dan fasilitas penunjang
kegiatan mahasiswa Kampus ITS.
Pembangunan IPAM Kampus ITS akan dilakukan dengan 3
tahap pembangunan. Pada tahap 1 memiliki kapasitas produksi
sebesar 6,5 L/detik. Unit-unit yang digunakan dalam IPAM Kampus
ITS adalah intake, koagulasi, flokulasi, sedimentasi, filtrasi,
desinfeksi, reservoir dan rumah pompa. Berdasarkan perhitungan finansial, pembangunan IPAM Kampus ITS akan membutuhkan
biaya sebesar Rp. 1.736.606.095 dengan biaya produksi dan O&M
sebesar Rp.1.976/m3. Hal ini lebih murah dibandingkan dengan
penyediaan air minum dari PDAM Surabaya sehingga dapat
mengurangi pengeluaran Kampus ITS dalam hal penyediaan air
berish. Namun demikian, pemanfaatan kolam dan drainase
sebagai penampungan air limpasan hujan yang digunakan
sebagai air baku pada kondisi eksisting tidak dapat memenuhi
kebutuhan air ITS. Sehingga diperlukan kajian lebih lanjut tentang
sistem drainase dan kolam penampungan air Kampus ITS.
===========================================================
According to its masterplan, ITS with the total
academicians of nearly 25,000 people, have the water demands of
17 L/s, while the rainfall intensity around this university which have
total area of 187 ha is 2,065 mm per year. Therefore, ITS have the
potential to utilize rainfall in order to supply it’s own water demand.
In order to meet the water demand independently and reduce the
water demand budgets, therefore the design of water treatment
plant in ITS is needed. There are two aspect that will be reviewed
in this design, which are technical and financial aspect.
In the preliminary research, raw water that comes from
rainwater runoff has water quality of 2. The water treatment plant
planned to be built in the location with total area 1,927 m2 in Jalan
Teknik Mesin ITS and there are 3 water treatment unit will be
established in that place. While the location of reservoir has total
area of 4.458 m2 and has depth around 4-5 m, where it is located
at 442 m from the water treatment plant. Utilization of reservoir only
50% from it’s capacity. The reason of this matter is because
reservoir also utilize as the entertainment area and supporting
facility for ITS student’s activity.
The construction of ITS water treatment plant will be done
in 3 steps. The first step has water capacity of 6.5 L/s. Water
treatment plant in ITS consist of intake, coagulation, flocculation,
sedimentation, filtration, disinfection, reservoir and pump house.
Based on financial calculation, construction of ITS water treatment
plant is Rp1,736,606,095 pond and O&M cost is Rp 1,976/m3. This
financial calculation show that this design is cheaper compare to
water supply cost of PDAM Surabaya, therefore it can reduce the
cost of water supply in this campus. Unfortunately, utilization of
pond and drainage that function as the reservoir of rainwater runoff that can be used as the raw water, in the existing condition not able
to provide ITS water demand. Therefore, there is a need to have
more review regarding drainage system and water pond in ITS.
