Kopaja

Koperasi Angkutan Jakarta or Kopaja (Jakarta Transport Cooperative) is a cooperative established in 1971 to provide public transport services in Jakarta. There were reportedly over 1,400 minibuses in the Kopaja fleet in mid-2012, more than half of which were estimated to be over 20 years old.

Kopaja buses have a rated capacity of 20-30 seats like the similar MetroMini service. Kopaja buses are green and white. But despite the nominal capacity of 20-30 passengers, Kopaja buses are often heavily overloaded. Safety is often compromised by this practice of overloading. In addition, the drivers are often reckless and do not pay attention to traffic signs and other traffic. Further, Kopaja diesel vehicles are often badly maintained and contribute significant amounts of pollution in Jakarta. In late 2012, in response to criticisms the chairman of the Kopaja organisation admitted that around 70% of the Kopaja buses were not road worthy but said that improvements would need support from the Jakarta government.
