Tourism more or less disappeared during World War II, Indonesian National Revolution and in the early years of the Sukarno era. On 1 July 1947, the government of Republic of Indonesia tried to revive tourism sector in Indonesia by establishing HONET ("Hotel National &amp; Tourism") led by R. Tjitpo Ruslan. This new national tourism authority took over many of the colonial heritage hotels in Java and renamed them all "Hotel Merdeka". After Dutch–Indonesian Round Table Conference in 1949, this tourism authority changed its name to NV HORNET. In 1952 the President formed the Inter-Departement 4 on Tourism Affairs which is responsible for reestablishing Indonesia as the world's tourism destination.
