BPPT Helps Search For KRI Nanggala-402 With A Magnetometer, Here's How It Works

DOCUMENTATION BETWEEN/KRI NANGGALA-402

JAKARTA - The Agency for the Assessment and Application of Technology (BPPT) is assisting in the search for the submarine of the Indonesian Navy KRI Nanggala-402 which has lost contact in Bali waters.

To assist in the search for the ship, BPPT's magnetometer was loaned. This tool has been installed at KN SAR Arjuna belonging to the National Search and Rescue Agency (Basarnas) to detect magnetic intensity anomalies in the search process for submarines in marine waters.

"The magnetometer is used to capture anomalous magnetic intensity which is quite strong," said Head of the BPPT Marine Survey Technology Center, Djoko Nugroho, quoted by Antara, Friday, April 23.

In addition, there is also a BPPT expert who is directly on the ship to operate the magnetometer.

"The important thing is that the sensor or magnetometer device is indeed after being captured, after the data is collected, it is processed immediately so that it becomes information. I think it requires special expertise," he said.

Djoko said that if a magnetic anomaly is found, a scan must be immediately carried out using a Multibeam Echosounder (MBES) sonar transmitter.

"Scanning with the Multibeam Echosounder equipment with a high level of accuracy such as the one in KR Baruna Jaya and the Side Scan Sonar will strengthen the search," he said.

The magnetometer device can detect magnetic anomalies or anomalies under normal conditions through magnetic intensity capture.

The ship carrying the device will be able to detect an increase in magnetic intensity at a certain point in the ocean, so it is hoped that the magnetic intensity of the submarine can be captured even if the ship is indeed sitting on the ocean floor.

From the point where the magnetic intensity appears, it is necessary to immediately collect data with the Multibeam Echosounder and Side Scan Sonar to obtain a picture of the possible objects that generate the magnetic intensity.
