Indonesia, the largest archipelago country in the world, with a population of 267 million, Indonesia has everything to become a more developed country, but behind it all have the potential for considerable natural disasters.
Tsunamis, earthquakes and volcanoes have become a part of the lives of Indonesians. Various large volcanic eruptions, powerful tsunamis to very destructive earthquakes have occurred from ancient times to the present.
Ring of fire is a common term that we often hear, an area that grows 75% of all volcanoes in the world and this is also home to 90% of the major earthquakes that have occurred in the world.
The end of 2004 was marked by a very strong earthquake in Aceh and caused a devastating tsunami that took more than a quarter of a million lives and missing people from areas around India. The end of the year humanitarian tragedy received extraordinary responses from the people of Indonesia and the world, both in efforts to provide assistance to the people of Aceh and North Sumatra affected by the disaster and efforts to reduce the impact of tsunam disasters in the future, not only in the Aceh region but throughout Indonesia. The said business is the development of the Indonesian Tsunami Early Warning System or the Indonesian Tsunami Early Warning System, which is abbreviated inTEWS.
Head of the BIG Geodetic Geodesy Control Network (PJKGG), Dr. Antonius Bambang Wijanarto, shared a little story about the background and ups and downs of the management of inaTEWS by the Geospatial Information Agency.
"What lies behind the existence of InaTEWS?"
The location of Indonesia which is in the fault zone of fault deduction and plate meeting makes Indonesia vulnerable to disasters, and many echoes centered at sea that triggered a tsunami, For that several ministries of institutions such as BMKG, BNPB, BIG, BPPT to Research and Technology consider the need for a warning system tsunami in Indonesia.
"What is the Work Process of InaTEWS itself"?
BIG is not directly related to inaTEWS because its main competency is at BMKG and BNPB, but BIG helps provide active sensors, such as tidal sensors, which can validate the potential for a tsunami or not then the data is sent to the relevant K / L.
"What are the Management Challenges"?
Currently our demands must be kept online for 24 hours, but the new condition is now recording data every minute sent to the server every 5 minutes, now we have to improve it faster than that.
"Future plans and expectations for inaTEWS"?
Reflecting from last year as there were disasters on the hammer and the Sunda Strait, we (BIG) are currently being asked to install 100 new tide pensions, as well as 120 CORS pensions, specifically for early warnings in the next three years, with these additional additions we hope that workers - HR especially at BIG can be more professional in carrying out their duties.
Twenty new tidal pensions are recorded, which will be installed in mid-2019, which are planned to be installed including Aceh, West Sumatra, North Sumatra, Bengkulu, West Sulawesi and Maluku. Coordination between ministries of institutions was also carried out to determine the strategic points of the installation of the tool, Although no one can answer with certainty what the ideal needs of tidal and CORS facilities in Indonesia due to the vast territory, but various efforts continue to be done especially by BIG and the government in create a more effective disaster mitigation system efficiently so that it can reduce the impact of disasters that can approach us all the time.
