Some 50 divers have joined the underwater search off the north coast of Jakarta, after a passenger plane crashed into the Java Sea on Saturday.
The military, navy and national police have all mobilized resources to help the search.
The first victim of the crash was identified on Monday.
"I asked this 'well-collaborated' joint team to concentrate on finding victims, because the victims' families have been waiting. Hopefully this can be completed quickly"
Indonesia's Transport Ministry has also ramped up its efforts to search for the black boxes of the crashed plane.
Since no distress signals were issued before the incident,. finding the flight recorders is critical in analyzing the cause of the crash.
Authorities were able to locate two black boxes on Sunday, but the search is not easy.
"There is a lot of silt on the bottom of the sea where the plane crashed, so the visibility is relatively poor, only about three-or-four meters. The black boxes are still being searched for"
Rescuers have retrieved human body parts and their personal belongings.
They've also found one of the jet's turbines, parts of the plane's tail and wheel, and an evacuation slide.
South Korea has sent a high-tech survey vessel to help the operation.
The Sriwijaya Air-operated Boeing 737-500 disappeared from radar on Saturday, just four minutes after it took off from Jakarta.
It had 12 crew and 50 passengers on board, all Indonesians.
It's the third major plane crash in the country in just over six years.
