Debris of (or from) KRI Nanggala recovered. The following is based on this report.
On April 24, 2021, the Indonesian Navy announced the finding of debris, including a part associated with torpedo tubes, a coolant pipe insulator, a bottle holding periscope grease, and prayer rugs.
Because the debris was found within 10nm of the
point of last contact and no other vessels were believed to be in the area, the
debris was believed to have come from KRI Nanggala, hence the submarine was
declared sunk.
Chief of Staff, Indonesian Navy, Admiral Yudo Margono stated that a sonar scan had shown Nanggala at a depth of just under 850m ie. fatally below its crush depth of about 500m.
On 25 April, after a more accurate sonar and
magnetometer scan by KRI Rigel (933) (an Indonesian Navy Hydro-Oceanographic Assistance Ship with more powerful sonar
equipment) the Indonesian Navy confirmed that all 53 of Nanggala’s crew were
lost.
Underwater scans have identified parts of the
submarine, including the rudder, external parts of the pressure hull, diving
plane, anchor, and other miscellaneous items such as the MK11 submarine escape
suit. The remotely operated vehicle (ROV) from Singapore Navy's MV Swift Rescue also made visual contact with the wreck and determined that KRI Nanggala had
split into three parts (broken up in fragments). Nanggala is located at a depth of 838m at coordinates
7°48′56″S 114°51′20″E Coordinates: 7°48′56″S 114°51′20″E."

Hi Pete
Indonesian People's Representative Council member Tubagus Hasanuddin alleged that the refit, performed by South Korea in 2012, may have failed and contributed to the incident [1]. But, no evidence was fund.

Member of Commission I DPR Maj. Gen. TNI (Ret.) TB Hasanuddin expressed his concern over the sinking of KRI Nanggala-402. The retired TNI officer suspected that KRI Nanggala-402 had retrofit failure.
For information, KRI Nanggala-402 has been retrofitted. For information, retrofitting is an activity of strengthening structures, adding components, to increasing capabilities.
"We express our deepest concern and condolences for the sinking of KRI Nanggala 402 which resulted in the death of 53 TNI martyrs," said TB Hasanuddin in a written statement on Sunday (25/4/2021).

“Daewoo Shipbuilding & Marine Engineering took over the submarine from Okpo Shipyard in Geoje-si, Gyeongnam in December 2009, and replaced the main equipment such as combat system, radar, sonar, etc. with a new type, and cut the hull and mounted it. It has carried out extensive performance improvement work, such as disassembling and servicing equipment.” (https://www.newswire.co.kr/newsRead.php?no=598586 )
A video apparently made by the KRI Nanggala's crew a few weeks prior to their unfortunate demise has surfaced:
