JAKARTA - The Agency for the Assessment and Application of Technology (BPPT) recommended the evacuation and search of the Sriwijaya Air SJ 182 aircraft to the Southeast East.

"From the results of computer simulations, the debris and pieces of the body will be carried to the Southeast East. So that the evacuation area will be directed to the area," said Head of the Center for Port Infrastructure Technology and Coastal Dynamics (BTIPDP), BPPT Widjo Kongko. January.

The recommendation is based on the results of the hydrodynamic simulation and particle distribution of the Sriwijaya Air SJ 182 aircraft carried out by BTIPDP BPPT.

Based on the results of the BPPT rapid assessment, the results of the calibrated hydrodynamic modeling show that the dominant current is towards the Southeast with a speed of less than 0.2 meters per second.

From the results of the "particle tracking" modeling, the direction of movement of the shale is estimated to be dominant to the east and southeast.

In the next two days up to 12 Jan 2021, debris is estimated to be east-southeast and has the potential to head to the northern coastal area of Tangerang Regency.

For a more accurate debris movement modeling, Widjo said that field data was needed in the form of the position and time when debris and or bodies were found during the search or evacuation.

On January 9, 2021 at 14:40 WIB, the Sriwijaya Air SJ 182 plane lost contact around Lancang Island, Seribu Islands.

BPPT, especially BTIPDP, was given the task of carrying out a Rapid Assessment of Hydrodynamic Simulation and the Distribution of Particles of the Sriwijaya Air SJ 182 Aircraft in the vicinity of the accident area.

This study was conducted to determine hydrodynamic conditions, particularly conditions of current speed and direction around the scene of the incident in the next few days.

In addition, the study can also estimate the area of particle movement due to hydrodynamic processes (tidal currents) and due to wind in the area.
