Instituted on 30 March 2015, this medal is divided into three ranks – gold (PSI I), silver (PSI II) and bronze (PSI III) respectively. The PSI I is reserved for royalty. The PSI II and PSI III are for civil servants and individuals who have demonstrated at least twenty years of distinguished service and loyalty to the Sultan.
On the obverse, the bust of Sultan Ibrahim is encircled with a wreath of gambier vines and pepper berries. This references the key role these crops played in the early development and modernisation of Johor. On the back is the Sultan’s cipher rendered in Arabic.
