Every September 30th, people in Indonesia are always reminded of the incident of the 30th-September Movement of the Indonesian Communist Party –PKI or better known as G-30 S PKI which is a black record of Indonesian history. On September 30, 1965, there were PKI rebellions in Jakarta and Yogyakarta and the kidnapping 10 officers of the Indonesian National Armed Forces . Seven of them were killed in Jakarta and three others in Yogyakarta.
The uprising on September 30, 1965 was not the first time for the PKI. Previously in 1948, the PKI had held a rebellion in Madiun. The aim of the rebellion was to replace the Republic of Indonesia with a communist state.
Shortly afterwards, the Commander of the Strategic Command of the Army (Kostrad) at the time, Major General Soeharto moved quickly, quelling the rebellion. The hunt for the G-30 S perpetrators was carried out quickly. The PKI was declared to be behind the violent takeover of power. They were hunted down and captured. Members of the organization who were considered sympathizers or related to the PKI were also arrested. Various community groups also destroyed PKI headquarters in various regions. They also attacked institutions, shops, offices and universities that were accused of being related to the PKI.
Some PKI leaders were tried at the Extraordinary Military Court, some were sentenced to death. PKI Chairman, DN Aidit who was accused of designing this movement together with PKI Special Bureau Chairman, Sam Kamaruzzaman fled to Central Java, but was later arrested, and killed. Then, the New Order government set 30 September as the Remembrance Day of the 30 September Movement and 1 October as the Pancasila Sanctity Day.
Indeed, the PKI G-30 S had long been crushed. The main culprits were arrested and tried. However, this does not mean that the Indonesian people are unaware of the communist threat. Communist ideology that does not recognize the existence of God is not appropriate for the Indonesian people with the Pancasila ideology which believes in God.
The Indonesian people do not want bloody tragedies like the PKI G-30 S to be repeated. However, even Chief of Indonesia Armed Forces, Marshal Hadi Tjahjanto acknowledges that communism is still a threat to the Indonesian people, so they must always be vigilant and anticipated for its existence because it could appear anytime and anywhere.
