Geography and Population density
(Source: Centre Bureau Statistic 2014)
the country stretches
1,760 km north to south
5,120 km east to west
1.9 million square kilometer
93,000 square km is water area
17,000 islands,
only 6,000 being occupied

7. IWRM is a process which
promotes the coordinated
development and
management of water, land
and related resources, in
order to maximize the
resultant economic and social
welfare in an equitable
manner without
compromising the
sustainability of vital
ecosystems.
(GWP, 2000)
Integrated Water Resources Management

8. according to Indonesia WR Law No. 7/2004
5 aspects
• Water Resources Conservation
• Water Resources Utilization
• Control of Water Destructive Power
• Water Resources Information System
• Community Participation
+ spatial planning and regional development
Law7/2004 has been ruled out by Court order No. 85/PUU-
XI/2013 18 February 2015, referred back to Law 11/1974
Water Resources Management aspects

9. • Since UU (Law) 7/2014 has been ruled out, for now the legal
basis referred back to UU 11/1974
• PERMEN PUPR 4/2015 (prevously Presidential Regulation
12/2012) – Basin Boundary (131 become 128 Basin In
Indonesia) – 6 cis become 3 basin
• PERMEN PUPR 10/2015 – Plan And Technical Plan Of Water
Management System And Water System (Pola and Rencana)
• PERMEN PUPR 34/2015 – River Basin Organisation
• PERMEN PUPR 17/2017 – Coordination team of Water
Resources Management (basin council)
PERMEN PUPR = Regulation of Minstry Public works and Housing
Legal Basis

16. Java Spatial model
•Java Spatial Model (integrated Spatial Plan and
IWRM)
•Impact on RTRW (Prov. Spatial Plan) and RDTR
(District Detail Spatial Plan)
•Impact of Land Use and Zoning
•Providing projection of land use in rural and urban
(with consequnces on water demand and emission
pollutant)
•Allocation of space from population and land use
in village level (conversion, land use change)
•Post processing to calculate water demand and
emission pollutant in water dsictrict
•Calculation of water demand in water distrcit,
connect (directly) to RIBASIM
