Before 21 October 1987, the former village of Loa Janan Ilir (lit. 'Lower Loa Janan') was part of
Loa Janan in Kutai Regency. From that date, it was transferred to
Samarinda Seberang, along with Loa Bakung and Loa Buah to
Samarinda Ulu (both then became part of
Sungai Kunjang in 1996). On 22 February 2006, Loa Janan Ilir ceased to exist as a village and split into three, namely Simpang Tiga (parent), Sengkotek, and Tani Aman. At the same time, Rapak Dalam was separated from Baqa (the two villages now belong into two separate districts). Loa Janan Ilir was reestablished as a district on 14 December 2010, by creating from southern parts (5 villages) of Samarinda Seberang. == Governance ==
