| Summary: | The lack of access to piped drinking water in Semarang City has resulted in
community dependence on groundwater or springs, which has the potential to
accelerate extreme land subsidence. To increase access to piped clean water in
Semarang City, which currently still reaches 60% service, the Semarang City
Government built Pudak Payung IPA to meet the clean water needs of Pudak
Payung Village and Gedawang Village. The potential increase in the amount of
water production needs to be balanced with a decrease in the level of water loss,
which is currently 47.58%. For this reason, it is necessary to design a water
distribution network to fulfil the RPJMN target of 100% by 2038, 14,440
networks and the establishment of an isolated system or DMA (District Metered
Area) to reduce the level of water loss in Semarang City to 20%. In achieving
these objectives, a quantitative analysis method is used, which is an approach in
which the process of data collection, field observation, data analysis, and
modelling is carried out with data certainty, calculation, and numerical. The
design of the planned distribution line must meet several technical and nontechnical criteria such as residual pressure, speed, and water quality, so that the
results of the distribution network are able to meet the maximum demand of the
service area in 2038 of 219,47L/s which is divided into 6 DMAs. From the results
of alternative selection using the SAW (Simple Additive Weighting) method,
through various parameters both technical and non-technical, alternative route 3
was chosen as the best distribution route. In addition, based on financial aspects
using the Net Present Value (NPV) and Benefit Cost Ratio (BCR) methods, the
design of the distribution network and the formation of the Pudak Payung IPA
DMA are economically feasible. |
