presiden indonesia yang terlupakan

Mr. Sjafruddin Prawiranegara

filling the power vacuum, Sjafrudin proposed the formation of an emergency government to continue the government of Indonesia.
In fact, at that time Soekarno - Hatta sent a telegram reads, "We, the President of the Republic of Indonesia reported that on Sunday 19 December 1948 at 6 am the Dutch had begun an attack on the capital city of Jogjakarta.
If under no circumstances the government can perform its obligations again, we authorize Mr. Sjafruddin Prawiranegara, Minister of Prosperity of the Republic of Indonesia to establish an Emergency Government in Sumatra.
But at that time the telegram was not up to Bukittinggi. However, at the same time Sjafruddin Prawiranegara has taken a similar initiative.
At a meeting in a house near the Sianok Bukittinggi Gorge on December 19, 1948, he proposed the formation of an emergency government.
Governor of Sumatra T.M. Hasan agreed to the proposal "in order to save the Republic of Indonesia which is in danger, meaning the emptiness of the head of government, which is an international requirement to be recognized as a state.
December 22, 1948, at Halaban, about 15 km from Payakumbuh, the PDRI was "proclaimed". Sjafruddin sits as chairman / president concurrently Minister of Defense, Information and Foreign Affairs, ad. interim.
The cabin helped by Mr. T.M. Hasan, Mr. S.M. Rasjid, Mr. Lukman Hakim, Ir. Mananti Sitompul, Ir. Indracahya, and Marjono Danubroto. General Sudirman remained as Commander of the Armed Forces.
Sjafruddin handed over his mandate to President Soekarno on 13 July 1949 in Yogyakarta. Thus, the end of the history of the PDRI for more or less eight months continued the existence of the Republic of Indonesia.

Mr. assaat

In the Round Table Conference Agreement (KMB) signed in the Netherlands, December 27, 1949 it was decided that the Netherlands submit sovereignty to the United States of Indonesia (RIS). RIS consists of 16 countries, one of which is the Republic of Indonesia. Other countries such as the Pasundan State, the State of East Indonesia, and others. Because Soekarno and Moh. Hatta has been designated as President and Prime Minister of the RIS, hence means a hollow leadership in the Republic of Indonesia.
Assaat is a Stakeholder While the President of the Republic of Indonesia. Assaat's role is very important. If there was no RI at that time, there would be a vacuum in the history of Indonesia that RI had disappeared and then reappeared. However, by acknowledging the existence of RI in the RIS which is only a few months, it appears that the history of the Republic of Indonesia since 1945 has never been interrupted until now. We know that then RIS merged into the Unitary State of the Republic of Indonesia on August 15, 1950. That means, Assaat has held the position of President of RI about nine months.
