as
from
an
extreme seawater temperature (~20C
warmer than average temperature). In the absence of
these symbiotic microalgae, the reef builder Scleractinian corals may not be existent and
dominate the reef any longer. The increasing CO2 emission in fact not only trigger global
warming and cause the reef to die from bleaching, but also affect ocean acidification that
eventually make coral to grow slower. Furthermore, due to the global growing economy and
development in thepastcentury,coastalcommunitieshave putevenbiggerpressures to the

through
destructive
fishing,
coral
mining,

and

Then, are we going to lose our valuable coral reefs? Indonesia as the center of the Coral

TheNetherlandsisalowlyingcountryprotectedbyanelaboratesystemofdikes.Withoutthese
dikes about 40% of the Netherlands would be flooded. The safety of these dikes is a major
concern for the coastal authorities. By law, these dikes must be monitored every five years
(2001, 2006, 2011, etc.) to assess the required level of protection. This check is based on

particularly
because
of
the

Precededbyseveral indepthstudiesthat includedvisits,observationsand intensivedialogues

researchgroupswithverypromising research capacitiesaswellasexcellent innovative ideas.
Yet, many of those researchers are not connected to each other and often have no
collaborations. Some time even same projects are redundantly executed by different groups.
Thus,thefirststeptowardhavingaresearchmap inCoastalZoneManagement istocreatea
structured
and
standardized

in
the
area.
This
idea
was
the
basic
of
our
application to APNCapable project. The proposal entitled Integrating IndonesianCapacityfor
CoastalZoneManagement was granted last year (2008) under Project Reference CBA2008
08NSYAndonowati.
Thedesignof theexpert database, and thecollectionofdata,started inSeptember 2008.A
questionnaire was designed and made online available on the APNproject website
www.labmathindonesia.or.id/apn. During the course of the project, however, the idea of
creatingthis
inventory
has
been
developed.
The
main
concern
is
how

Essential principles of fluiddynamics for surface water waves are thebasis of the Variational
BoussinesqModel (VBM) that is indevelopment incollaborationbetweenLabMathIndonesia
and the University of Twente. This model has exact energy conservation, incorporates
approximatedispersionpropertiesandcandealwithsteepbottomvariations,withcalculations
thatcan

horizontal

only.
In this lecture we present some results of simulations performed with a numerical Finite
Element implementation on an unstructured grid of the VBM. Geophysical problems are
characterized by the presence of length and time scales that can be orders of magnitude
different,whichcreatesspecificneedforattentionforreliablesimulations.

West Java is an important province in Indonesia since it close to the capital city of Jakarta and
playsanimportantroleintheeconomicalactivitiesinthecountry.Theprovincehastwoseas,the
Java Seaon the northern part and the IndianOceanon thesouthernpart. Unlike the southern
coast, thenorthern coast of West Java is characterized by the presence ofbroad deltaic plains
builtoutintotherelativelylowwaveenergymicrotidalenvironmentoftheJavaSeabysiltladen
rivers.Thesedeltasareformedbymud,sandandothersedimentsresultingfromsiltation inthe
mouth of the rivers. The length of coastline on the northern coast is about 365 km and highly
dynamic due to erosion process. It is important to study ocean and coastal characteristics to
supportourknowledge in thedynamic of coastal area,especially if it is referred to the climate
changes. The characteristics can be analyzed through comprehensive studies covering
measurements and numerical simulations of oceanographic parameters. Simulation on the
oceanographic

and

during
the
periodof19982008ontheNorthernCoastofWestJavaProvince,Indonesiawasinvestigatedin

Thispaperpresentsdocumentationofrecentregionalenvironmentalsettingsanddiscussionof
current measures of local adaptation practices in Seribu islands, southwest of Java sea,
Indonesia,focusingonPramuka,Panggang,KaryaandSemakDauncays.Socioeconomicprofile
of the studied site in terms of demography and Gross Domestic Product, as well as land use
practices are also considered. The discussion is related to increasing risks of erosion and
inundation.Recent regionalenvironmentalsettingsare representedbytheprevailingregional

to overtopping of water during high spring tide and erosion due to wave attack. Local
inhabitants seem to possess sufficient awareness to the currently progressing environmental
changes. It seems that their role as key player of subsistence economy prevents effective
applicationofsustainableconservationstrategy.

contributors to the conservation and adaptation measures in Seribu islands. Still, local
anthropogenic adaptation practices lead to the demotion of local natural environmental
