context: 10 pieces of boards returned to Jenebora out of 1,000 pieces requested by the Sultan of Kutai as donations for building materials for the construction of the New Kutai Lama Palace. The ten back boards are called by the people of Kutai Balikpapan Tu. So that the area along Balikpapan Bay, precisely in Jenebora, is called Balikpapan. [10] The Pasir Balik tribe (a native of Balikpapan) is a descendant of grandfather and grandmother named Kayun Kuleng and Papan Ayun. So the area along the Balikpapan Bay is called Kuleng-Papan or its meaning Balikpapan (in Paser language, Kuleng means Balik). In another legend also mentioned the origin of Balikpapan, namely from a princess who was released by her father a king who did not want her daughter to fall into enemy hands. The princess who was still a toddler was tied on a number of pieces of the board in a lying state. Because the current carried and hit by the waves, the board is reversed. When the board washed ashore found by a fisherman and so behind it turned out there was a daughter who was still in a bound state. It is said that the princess was named Putri Petung who came from the Sand Kingdom. So the area where it was discovered was called Balikpapan. The anniversary of the city of Balikpapan is the date February 10, 1897. Determination of this date is the result of the Balikpapan History Seminar on December 1, 1984. This February 10, 1897 was the date of the first oil drilling in Balikpapan conducted by the Mathilda company as a realization of the terms of cooperation between J.H. Menten with Mr. Adams of Firm Samuel and Co. [11]
