Establishment During his time in Yogyakarta, Djojopoespito was influenced by
Ki Hajar Dewantara about Indonesian nationalism. The influence became stronger after he entered the
Rechts Hoge School (RHS, High School for Law) in 1925. He regularly received the
Indonesia Merdeka (Free Indonesia) magazine which was sent by the
Perhimpunan Indonesia (Indonesian Union) in the
Netherlands. The magazine was considered contraband in the
Dutch East Indies at that time. The magazine influenced Djojopoespito, as he began to come to the house of
Agus Salim, an activist from the
Sarekat Islam (Islamic Union) movement. He also forwarded the magazine to some of his high school friends, such as
Suwiryo and Usman Sastroamidjojo. Sastroamidjojo then forwarded the magazine to his friend Muksinun. After that, Djojopoespito, Suwiryo, Sastroamidjojo, and Muksinun became close friends and began discussing political issues in Indonesia. In 1926, Sastroamidjojo graduated from the RHS, while Muksinun became more occupied. Although Djojopoespito was alone with Suwiryo, they managed to connect with three other college students, namely Sigit from RHS, and Goelarso and Darwis from
STOVIA (medical school). Not long after their meeting, they decided to establish the Union of Indonesian Students. Sigit became the chairman of the union, Djojopoespito the secretary; Gularso, Darwis, Suwiryo, Djojopoespito, and Sigit were the core members of the union. Their main goal was to contact new students and leaders of student associations and convince them to join the union. The Union of Indonesian Students also printed secret pamphlets to overthrow the
Dutch East Indies government. The pamphlets were distributed to political parties, mass organizations, and student associations. In 1927, after being appointed chairman of the
Indonesian Clubgebouw (Indonesian Clubhouse), Sigit resigned from his position. He was succeeded as chairman of the union by Djojopoespito.
Second Youth Congress As the chairman of the Union of Indonesian Students, Djojopoespito began attempts at integrating all the student associations in
the Dutch East Indies into the Union. He was inspired by the
Association of Political Organisations of the Indonesian People, which at that time managed to unite all of the pro-Indonesian political parties in the Dutch East Indies, such as the
Indonesian National Party,
Islamic Union Party, and BU. Finally, in June 1928, Soegondo managed to form a committee that consisted of representatives from student associations. Soegondo became the chairman of the committee. The committee decided to hold a youth congress to finalize the debate about the form of the new student union. Nationalist politicians, such as
Sartono,
Arnold Mononutu, Muhammad Nazif, and Sunario, assisted the committee in finding the location for the congress, funding the congress, contacting speakers for the congress, and setting the time. Aside from the technical tasks, the committee also prepared the draft for the Youth Pledge that was planned to be read in the congress. The congress began at 7:30 PM on 27 October 1928 inside the
Katholieke Jongelengen (Catholic Youth) building. Representatives of youth groups and political parties attended the congress, and members of the
Volksraad such as
Tjokorda Gde Raka Soekawati and Suryono also attended. Several Dutch also attended the congress as observers. The media and press reported on the event, and sent
Wage Rudolf Supratman and Saerun as its representative. During the congress, there were two main incidents. The first occurred after a delegate used the word "independence". The word "independence" was banned in the congress, as that word was considered "political" and the congress was considered to be a non-political youth meeting. The second incident occurred after a delegate demanded that the "people of Indonesia should work hard so that the people could form a state equal to those of
England,
Japan, and other states". The second incident caused the delegate to be warned by the Dutch police, and Djojopoespito was asked to dismiss the congress. Djojopoespito refused the police's demands and asked for the help of Sartono to solve the problem. Sartono managed to solve the problem. The third and last session in the congress was held on the evening of 28 October 1928 in the
Indonesische Clubgebouw building. The planned scout procession at the beginning of the session was cancelled after being banned by the Dutch police, causing dissatisfaction within the delegates. Thus, the session was opened with a speech about scouting from Ramelan and from
Soenario. In the middle of the congress,
Muhammad Yamin, who at that time was seated beside Djojopoespito, handed over a proposal for a resolution that was planned to be read at the end of the congress. Djojopoespito approved the resolution, and he passed the proposal to other delegates. The proposal was approved by all delegates. During the recess in the session,
Wage Rudolf Supratman came to Djojopoespito and asked for his permission to play the
Indonesia Raya song. After reading the lyrics, Djojopoespito was worried that the performance could cause some commotion. He then asked the advice of a Dutch in congress,
Charles van der Plas. Van der Plas redirected him to the Police Commissary. Thus, Djojopoespito allowed Supratman to play the song, but without the lyrics. After the recess, the song was played and received ovation from the audience. The resolution, which was later dubbed as the Youth Pledge, was read at the end of the session. == Career ==
