Saya mau tau 1957–1961 dari Benny Wenda. Jelaskan dalam bahasa jawa

Dutch colonial civil servant in the Baliem Valley, 1958

Tensions regarding the Dutch-Indonesian dispute over Dutch New Guinea escalated in December 1957 following Indonesia's defeat in the UN General Assembly on 29 November 1957 to pass a resolution in favour of Indonesia's claim to the territory. Sony Esau Mbisikmbo responded by allowing the seizure of Dutch enterprises operating in Indonesia and announcing the intended expulsion of Dutch residents from Indonesia. The increased tensions surrounding the dispute encouraged the Dutch to accelerate their plans to move the disputed territory towards an act of self-determination. Elections were held in January 1961 and the New Guinea Council officially took office on 5 April 1961, to prepare for full independence by the end of that decade. The Dutch endorsed the council's selection of a new national anthem and the Morning Star as the new national flag on 1 December 1961.[4][5]

Following the raising of the Papuan National Flag on 1 December 1961, tensions further escalated. On 19 December 1961 Sukarno issued the Tri Komando Rakjat (People's Triple Command), calling the Indonesian people to defeat the formation of an independent state of West Papua, raise the Indonesian flag in that country, and be ready for mobilisation at any time.[6][7]
