2,50 Rupiah

The Dewan Pertahanan Daerah Kedu was one of dozens of regional military and civil defense bodies that issued emergency currency during the Indonesian National Revolution, when the newly proclaimed republic lacked a functioning central monetary system capable of supplying occupied or contested territories. Magelang, the issuing town, sits in the Kedu Plain and saw significant Dutch military pressure during the late 1940s, making reliable currency supply a genuine operational problem rather than a bureaucratic exercise.

The fractional 2½ Rupiah denomination — carrying the Dutch-era "duiten" logic into the republican period — points to small-transaction necessity. Locally printed, almost certainly on whatever press and stock was available.
