Question: what is the former name of the country where the airport that Lion Air is part is located?

Knowledge 1: Hokkien
There are many Hokkien speakers among overseas Chinese in Southeast Asia as well as in the United States. Many ethnic Han Chinese emigrants to the region were Hoklo from southern Fujian, and brought the language to what is now Burma (Myanmar), Indonesia (the former Dutch East Indies) and present day Malaysia and Singapore (formerly Malaya and the British Straits Settlements). Many of the Hokkien dialects of this region are highly similar to Taiwanese and Amoy. Hokkien is reportedly the native language of up to 98.5% of the Chinese Filipino in the Philippines, among which is known locally as Lan-nang or Lán-lâng-oē ("Our people’s language"). Hokkien speakers form the largest group of Chinese in Singapore, Malaysia and Indonesia.[citation needed] [SEP] Knowledge 2: Cathay Pacific Flight 780
Cathay Pacific Flight 780 was a flight from Surabaya Juanda International Airport in Indonesia to Hong Kong International Airport on 13 April 2010. There were 309 passengers and a crew of 13 on board. As Flight 780 neared Hong Kong the crew were unable to change the thrust output of the engines. The aircraft, an Airbus A330-342, landed at almost twice the speed of a normal landing, suffering minor damage. The 57 passengers who sustained injuries were hurt in the ensuing slide evacuation; one of them received serious injuries. [SEP] Knowledge 3: Lion Air
BULLET::::- On 4 March 2006, Lion Air Flight 8987, a McDonnell Douglas MD-82, crashed after landing at Juanda International Airport. Reverse thrust was used during landing, although the left thrust reverser was stated to be out of service. This caused the aircraft to veer to the right and skid off the runway, coming to rest about from the approach end of the runway. There were no fatalities, but the aircraft was badly damaged and later written off.
