100 Rupiah Djepang Japanese Rupiah

This note was issued not by a national authority but by a regional defense council — one of dozens of ad hoc bodies that emerged across Sumatra during the Indonesian National Revolution, when the Dutch were attempting to reassert colonial control and central Republican institutions had limited reach beyond Java. Palembang, as a major oil-producing center, was a particular flashpoint; the city had seen heavy fighting in early 1947.

The "Djepang" designation in the name refers to the Japanese-occupation rupiah still circulating as the dominant paper currency in the region — this note was denominated and valued relative to that wartime scrip, not the Republican rupiah being established elsewhere. Local printings of this type are typically crude, produced under duress with whatever materials were at hand.
