PT Industri Kereta Api (Persero), abbreviated as INKA, is a rolling stock manufacturer.^[1] It is completely owned by the Government of Indonesia.

Profile[]

INKA-made LRT Palembang rolling stock

INKA Ltd was established in 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. Its first Madiun Locomotive Plant was converted from a former PJKA steam locomotive overhaul facility. Under Suharto's presidency INKA was initiated as part of the national strategic industry, as the basis of a national rail production industry. As such, INKA focused on dominating the domestic market and to win competition in the ASEAN region and developing countries.

INKA has produced or refurbished every batch of KAI's passenger cars, excluding multiple units, since 1985. Its production of multiple units began in 1987 when it assembles Rheostatik EMUs from Japan. Since then, INKA utilises lightweight stainless steel car bodies and modern AC traction control with VVVF inverters (formerly GTO, now IGBT) for EMU production. INKA started producing diesel multiple units in 2007 with orders from Ministry of Transportation for regional and commuter trains. INKA has supplied various freight wagons to KAI, most notably the coal transport wagons supporting coal mining industry in Ombilin (West Sumatra) and South Sumatra.

In 2019 PT INKA (Persero) cooperated with PT Len Industri (Persero), PT Wijaya Karya (Persero) and PT Kereta Api Indonesia (Persero) to collaborate on business development by forming a consortium of Indonesian Railways Development Incorporated for Africa (IRDIA), targeting African countries.

In addition, INKA Ltd has, together with KAI, established cooperation with Swiss rolling stock manufacture, Stadler Rail established a joint venture to build a rolling stock factory in Banyuwangi, East Java. This cooperation was intended to assist Indonesian government in developing Indonesian transportation system.

Automotive industry[]

In 2008, INKA proposed GEA (short for Gulirkan Energi Alternatif) as a national car. A prototype was created in 2008.^[5] In 2009, GEA began using the machinery developed by , Rusnas, after previously using Chinese machinery. Carburetors are the only imported component in the 2009 prototype.

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:

Inobus ATC 320 (Articulated Car) (produced year 2011–2012) with Cummins Westport ISL-G 320 HP CNG engine, mated with Voith DIWA 864.3E automatic transmission.

39 units were operated in total, with 21 units operated by Perum DAMRI from 2011 to 2018 and 18 units operated by PT. Bianglala Metropolitan from 2013 to 2016. The main difference between the two is DAMRI operated units used Songz Air Conditioning whilst Bianglala operated units used Denso Air Conditioning.

Inobus SGL 290 (Single) with Doosan GL11K 290 HP (EPA 2010) CNG Engine, the same engine used in current Zhongtong buses, mated with Allison Transmission T350R automatic. A total of 36 units, should have been operated by Perum PPD.
Future fleet: Inobus ATC 340 (Articulated Car) with Doosan GL11K 340 HP Euro IV CNG Engine, the same engine used in current Zhongtong buses bus, mated with Voith DIWA 864.5 automatic transmission.^[6]
