Presentation by Mr. Irfan Sudono, MT Research Center for Water Resources – Ministry of Public Works and Housing (Indonesia) at the Seminar Hydro Software to support policy development and real-time decision making, during the Deltares Software Days South-East Asia 2019. Wednesday, 27 November 2019, Bangkok.

Challenges in Indonesia
1. Population increases, lifestyle changes, the need for water increases
2. Urbanization (ground water extraction, deforestation, increasing water demand
3. Environmental damage, (causing DF, erosion, sedimentation, and pollution)
4. Climate Change
Report from the IPCC (Intergovernmental Panel on Climate Change) in 2013.Confirming that
in the future at the beginning of the 21st century (2016-2035) and the end of the 21st
century (2081-2100), on a global scale the climate projection will get worse
1. The incidence of heavy rain (both in terms of frequency, intensity, or amount) will
increase with the category "very likely"
2. While the intensity and duration of drought are in the category of "medium
To tackle Indonesia’s challenges on Water Resources Management, it is essential that all existing water
data is available for the stakeholders.
Currently the data, are spread over the institutes and organisations that are involved in integrated
PusAir and BMKG took the initiative to set-up a joint Pusat Studi Hydroinformatics (PSH, or Water
Centre of Excellence) which it should form the platform that connects most of the activities and
disseminates the results to the stakeholders.
The PSH is supported by a dedicated server system, running the software, tools, databases and
interfaces that are produced within the whole JCP program.
Delft-FEWS hydrological model and data integration platform used as the platform software to
accommodate all functionalities required for the SI-PSH.

WEBSITE of PSH
❖ Stakeholders/users can see the data and information on web portal but can’t download the data.
❖ Only certain users and administrator can download data.
❖ For users who need the data or more information, they can contact the officer directly or can fill out a
data request form.
✓ The address: The PSH website still under development (on localhost) and is expected to be online and
publicly accessible later this year (2019).
✓ The planning: to facilitate water resources data and information on R&D results.
✓ Another function is to facilitate data from SI-PSH.
