Bank Indonesia issued Regulation Number 11/8/PBI/2009 to amend the specifications of the 2005 issue 50,000 Rupiah banknotes, primarily updating the year of issuance to 2009 and enhancing security features. The regulation details specific design elements for the obverse and reverse sides, including the depiction of Hero I Gusti Ngurah Rai and Lake Beratan, alongside technical requirements for paper material and ultraviolet-reactive inks. Additionally, Article 5A explicitly declares that previously issued 50,000 Rupiah banknotes remain legal tender and have not been revoked from circulation.
