Abstract
Water quality will decrease as the distant distances away from the reservoar
so Minister of Health Regulation No. 736/Menkes/SK/IV/2010 is issued by the
government as the quality standard for drinking in Indonesia of 0.2 mg / l at the farthest point of the distribution network to avoid contamination of
microorganisms. The results of the evaluation of the quality of the production water cannot guarantee the quality of the customer's water, especially the customers who are away from the water treatment plant.
This study used STELLA, a dynamic model programming, to provide a
simple and systematic description of the variables that affected the water supply
company in Indonesia (PDAM) distribution network to be simulated into 3 (three)
main scenarios, they were moderate scenario, pessimistic scenario, and optimistic scenario that will be the reference in the selection strategy based on environmental aspects and financial aspects.
This research showed that the dynamic model of PDAM distribution
network is influenced by many factors that influenced each other in causal
relationship such as pipeline leakage, water flow production, water flow
distribution, distribution distance, water velocity, major headloss, pipe crosssectional area, pipe diameter, pH, chlorine residual, Escherichia coli, and water flow. Simulation results showed that in pessimistic scenario with 50% of pipe
leakage and optimistic scenario with 20% of pipe leakage indicated that the higher pipe leakage rate the closer disinfection post distance should be built from the
water treatment plant. Strategy could be applied based on environmental aspect,
that is quality improvement and production water flow as well as improvement of
water quality in customer while based on financial feasibility aspect with Net
Present Value (NPV) obtained Rp. 186.017.856.110,-, 5.66 of Benefit Cost Ratio (BCR), 7.51% of Internal Rate Return (IRR) and Payback Period (PP) was a year
and 3 months then the development of IPAM Ngagel II distribution network is
feasible to be implemented.

K
ualitas air akan
menurun
seiring semakin
jauhnya jarak distribusi dari
instalasi pengolahan
sehingga
diberlakukan
Permenkes No. 736 tahun 2010
yang
mensyaratkan
adanya
kadar sisa klor sebesar 0,2 mg/l
pada
titik terjauh dari
jaringan distribusi
untuk meng
hin
dari
adanya
kontaminasi mikroorganisme
.
H
asil
evaluasi kualitas air produksi tidak dapat menjamin kualitas air pelanggan
khususnya pelanggan yang berada jauh dari instalasi pengolahan air.
Penelitian ini menggunakan model dinamis STELLA untuk
memberika
n
gambaran sederhana dan sistematis mengenai
variabel

variabel
yang
mempengaruhi
jaringan distribusi
PDA
M
untuk kemudian disimulasikan ke
dalam
3 (tiga) skenario utama, yaitu skenario moderat, skenario pesimis, dan skenario
optimis yang akan menjadi acuan
dalam pemilihan strategi berdasarkan aspek
lingkungan dan aspek finansial.
Penelitian ini menunjukkan bahwa
m
odel dinamis jaringan distribusi PDAM
dipengaruhi oleh banyak faktor yang saling mempengaruhi dalam hubungan
sebab
-
akibat
seperti
kebocoran pipa
, debit air produksi, debit air distribusi, jarak
distribusi, kecepatan air,
headloss mayor
, luas penampang pipa, diameter pipa
,
pH
, sisa klor,
Escherichia coli
, dan debit air.
Hasil simulasi pada skenario pesimis
dengan kebocoran pipa sebesar 50% dan sken
ario optimis dengan kebocoran pipa
20% menunjukkan bahwa semakin tinggi tingkat kebocoran pipa maka semakin
dekat jarak pos desinfeksi yang harus dibangun dari instalasi pengolahan air.
S
trategi yang dapat diterapkan
berdasarkan aspek lingkungan
,
yaitu
pen
ingkatan
kualitas dan debit air produksi
serta
peningkatan kualitas air di pelanggan
sedangkan jika ditinjau
b
erdasarkan aspek kelayakan

dengan
Net Present

(NPV) diperoleh Rp.

Benefit Cost Ratio

sebesar

,
Internal Rate Return
(IRR) sebesar
7,51
%, dan
Payback Periode

adalah
1 tahun 3

maka
pengembangan jaringan IPAM Ngagel II layak untuk
dilaksanakan.
