In 1992, KRI Ki Hajar Dewantara, along with KRI Yos Sudarso and KRI Teluk Banten intercepted the Portuguese ship Lusitania Expresso in East Timor. Col. Widodo, deputy assistant of the Indonesian Navy´s Eastern Fleet, told Radio Republik Indonesia from aboard the Indonesian warship KRI Yos Sudarso that the ferry entered Indonesian waters at 5:28 a.m. local time on March 11, 1992. At 6:07, the Lusitania Expresso had traveled two to three nautical miles (3.7 to 5.6 km; 2.3 to 3.5 mi) into Indonesian territory and Captain Luis Dos Santos (Lusitania Expresso's captain) was ordered to leave immediately. Col. Widodo said the Portuguese ship captain obeyed the order and turned his ship around and headed back to sea.[2]
