Singapore and Indonesia officially launched the Indonesia-Singapore (INDOSIN) Defence Alumni initiative on Tuesday, July 14, in Jakarta. The program, known as Persahabatan Alumni Pertahanan (PERSAHAN), aims to formalize and maintain professional and personal ties between generations of military officers from the Singapore Armed Forces (SAF) and the Indonesian National Defence Forces (TNI).
Establishing the PERSAHAN Initiative
Singapore Minister for Defence Chan Chun Sing and his Indonesian counterpart, Sjafrie Sjamsoeddin, presided over the launch in Jakarta. During the event, the two ministers signed the initiating directive and unveiled the official logo for the program. According to Singapore’s Ministry of Defence (MINDEF), the initiative serves to connect officers who have participated in training programs and courses hosted by either nation.

The name PERSAHAN is derived from Indonesian terms meaning “friendship” and “defence alumni.” By creating a structured network, the initiative seeks to strengthen people-to-people ties between the two countries, extending these connections beyond the active service years of the participating officers.

The strategic direction of the alumni group will be managed by the chiefs of the defence forces of Singapore and Indonesia, who serve as co-presidents.
