50 000 Rupiah

Perum Peruri — the state security printing works — has handled Indonesian banknote production since its founding, and this series was among the notes produced at the Karawang facility after it absorbed capacity from the older Jakarta operation. Mujirun's engraving credit is relatively rare for Indonesian notes of this period; named engravers appear infrequently in Peruri's production records, making the attribution on this issue worth noting.

The 2005 series introduced revised security threading and watermark specifications responding to a wave of sophisticated counterfeits that had troubled the previous 50,000 Rupiah type in the early 2000s.
