PT Industri Kereta Api (Persero), abbreviated as INKA, is an Indonesian state-owned rolling stock manufacturer.

[1] INKA Ltd was established in by the Indonesian government in May 1981 to serve as the national rail locomotive and rolling stock manufacturer for the Indonesian Railway Company (PT Kereta Api Indonesia (Persero)) in its revenue lines in the islands of Java and Sumatra and to manage the steam locomotive PJKA in Madiun which was planned to be converted into a railway infrastructure factory.

Various sensors such as cameras, radar, LiDAR, and GNSS are installed to detect objects in the vicinity, both in sunny and rainy weather conditions.

The information captured by these sensors is processed by artificial intelligence (AI) through embedded computing devices, which allows the tram to make decisions independently.

Since then, INKA has utilized lightweight stainless steel car bodies and modern AC traction control with VVVF inverters (formerly GTO, now IGBT) for EMU production.

INKA started producing multiple diesel units in 2007 with orders from the Ministry of Transportation for regional and commuter trains.

PT Inka also supplied compressed natural gas-powered (CNG) buses for TransJakarta, mainly known as the name brand Inobus (abbreviated as Innovation Bus).

Currently, there are three known product variants: In 2011, INKA produced Kancil, a 404 cc vehicle planned to replace auto rickshaws.

[12] In 2022, INKA announced that the two will continue the production of Red and White electric buses after reportedly signing a Cooperation Agreement.

The news was announced by ITS Vice Chancellor IV Bambang Pramujati who explained that the two entities will produce five electric buses.
