| Abstrak/Abstract |
Since 2014, Universitas Gadjah Mada (UGM) has
established Drinking Water Supply System (DWSS). DWSS
established in UGM is in line with Indonesian Government’s target to
fulfil needs for 100% drinking water access in 2019. In order to
improve the system’s sustainability, planning and monitoring through
mapping and 3D modeling of DWSS network distribution are needed.
DWSS is expected to not only be well distributed but also to be easily
monitored and accessed by student and staff in UGM.
The purpose of this paper is to present the utilization of 3D GIS
to map water dispenser location and to model the distribution of
pipeline network. It also focuses to assess the appropriateness of the
planned water supply for fulfilling the need of drinking water in each
faculty. In addition to that, the map of water dispenser finder is also
developed to support campus community in finding the nearest
drinking water facility. Data acquisition of water location has been
done by using Handheld GPS, while data processing and
presentation of DWSS in 3D format are done by using AutoCad 2009,
ArcGIS for Desktop 10.3.1 (ArcScene and ArcMap), while Sketch Up,
ArcGIS Online, and CityEngine Web Viewer are used to model and
visualize the 3D map.
This project produces Geographic Information System of DWSS
in UGM. The 3D GIS of DWSS encompasses the map of distribution
of water dispensers, the 3D model of network distribution of drinking
water supply, and analysis of planned water supply in order to assess
the drinking water needs in each faculty. The map of distribution of
water dispensers is a map depicting distributed water dispenser in
UGM. 3D map of network distribution of DWSS is built by combining
multiple datasets including UGM’s Digital Terrain Model (DTM),
3D model of campus building, 3D model of pipeline network, 3D
model of water dispensers and reservoirs. 3D network distribution
modeling of DWSS is presented offline by using ArcScene 10.3.1
software and presented online by using CityEngine Web Viewer.
From GIS analysis, it is found that the planned water supply has not
answered the need of drinking water in each faculty. It can be seen
that need of drinking water has reached 218.870 litres per day,
whereas the planned supply is only 3.889,30 liters per day. |
