Bidar Alam is a nagari (village) in Sangir Jujuan, South Solok Regency, in the Indonesian province of West Sumatra, with a population of over 3,000 people.

[1] In late 1948 and early 1949, the Emergency Government of the Republic of Indonesia (PDRI) moved inland to evade Dutch pursuit, initially from the city of Bukittinggi, then to Payakumbuh, before leaving urban settlements.

Supported by Indonesian Air Force personnel, PDRI established a mobile radio station at the town to communicate with the outside world.

[5] The relative safety at the village allowed PDRI to communicate with guerrilla fighters in Java and consolidate a provisional government.

[6] Compared to the other towns and villages which the PDRI had been based from, Bidar Alam hosted it the longest, for three and a half months.
