Prediction of the Indonesia Independence Day
Ronggowarsito lived during the Dutch colonial period. He witnessed for himself how the Javanese people suffered, especially when the Cultivation Program was implemented after the Diponegoro War. In this apprehensive atmosphere, Ranggawarsita predicted the coming of independence, namely later in the year of Wiku Sapta Ngesthi Janma.
The sentence consisting of four words is contained in Serat Jaka Lodhang, and is a Suryasengkala sentence which, if interpreted, will result in the number 7-7-8-1. Suryasengkala’s reading is reversed from back to front, namely 1877 Saka, which coincides with 1945 AD, the year of the independence of the Republic of Indonesia.
