Warukin Airport — Tanta-Tabalong, Indonesia

Warukin Airport, coded TJG, is a small airfield located in Tabalong Regency, South Kalimantan, on the Indonesian portion of Borneo. The airport primarily supports limited domestic flights connecting the region to larger hubs like Banjarmasin, serving local residents and businesses tied to the area's coal mining and agricultural industries. Surrounded by tropical forest and river systems typical of Kalimantan, Warukin remains a modest facility without extensive passenger infrastructure. Its role is largely functional, providing air access to a part of Borneo that otherwise depends heavily on road and river transport. TJG reflects the broader pattern of small regional airports scattered across Indonesia's outer islands.
