Objectives of System Design

1. Natural disaster spreading which is rapid,
   precise and cost effective.
2. Stage of system design aims to find the optimal
   form of the application to be built by
   considering a variety of factors, problems and
   needs that exist in the system.
3. Improve the preparedness of the community to
   reduce the potential loss.

Technology Developments inEarly Warning System
for Tsunami

• Early warning (early warning system) tsunami
  which serves as a warning or emergency alarm if
  at any time the tsunami came unexpectedly.
• Need technology such as SMS Gateway in
  Aceh-Indonesia, DART (Deep-ocean Assessment and
  Reporting of Tsunamis) systems in Hawaii and many
  others like in Japan, etc.

SMS Gateway

• The instruments of system
• Ranet (Radio Internet)
• Ranet is a technology that serves
  ascollaboration tools related to
  meteorologicalInternational and similar services
  that workto improve and control the area
  perdalamanof the community access to weather,
  climate and informationrelated.

5

• SMS Gateway
• is a platform that provide a mechanism for EUA
  (application require the use of SMS) deliver and
  receive SMS from mobile devices (HP, PDA phone,
  etc.)
• HTML
• is stands for Hypertext MarkupLanguage. HTML is
  used to create the page web.

6

• d) Web Server
• is Web servers are the backbone of the www.Web
  server uses a protocol called the HTTP (Hyper
  Text Transfer Protocol).
• e) PHP (Hypertext Preprocessor)
• It is the language of form scripts placedthe
  server and processed in server.
• f) Database
• is a collection of information stored in the
  computer in a systematic so it can be checked
  using a program computer to obtain information
  from the database them.

All of the information/data from tsunameter,
seismic and accelerometer, tide gauge and GPS
Server interface
15

• RANET with satellite (worldspace) communication
  line.
• BMKG has developed a system dissemination of
  information and early warning earthquake RANET
  the tsunami with technology use of WorldSpace
  satellite communication channels earthquakes to
  link data from the server RANET to server 5 in 1
  SMS gateway.
• The system then deploy SMS, fax and alarm warning
  to registered customers on server 5 in 1 when the
  earthquake and tsunami.

16

• RANET with internet communication line is
  modification based on satellite line.
• The server receive earthquakes information every
  30 second from BMKG then sending the message
  through SMS automaticly that has registred on
  BMKG website (www.bmkg.go.id).
