Koperasi Angkutan Jakarta or Kopaja 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. Despite these problems the Kopaja bus service, like other low-cost bus transport options such as the small local Angkot vans, is a key part of the Jakarta transport network. There are numerous routes which crisscross the city and link into the Transjakarta Bus Rapid Transit system. Fares, at Rp 2,000 per ride for most services, are cheap. Efforts to upgrade the service by introducing newer air-conditioned Kopaja buses in 2012 have so far attracted limited custom because passengers are reluctant to pay the higher Rp 5,000 price for the higher-quality buses. Other attempts are made from time to time by the Jakarta Government to improve services; in late 2015, for example, it was announced that the Government would provide new, larger buses on one of the Kopaja routes and tighten up fare arrangements on the route. It is not uncommon for buskers, often children, to jump aboard the Kopaja minibuses. However apart from hoping for a small contribution they rarely cause any trouble at all to passengers.
Routes
Kopaja buses are numbered and travel along designated routes. The numbers are sometimes a little hard to spot since they are posted in a somewhat random fashion on the buses, usually on the front and back windows and sometimes on the side windows as well. There are also designated bus stops but the bus stops are rarely used. Rather, passengers just wave down the slowly travelling passing buses and later just indicate the spot where they wish to alight. Conductors hanging out of the front or rear doors of the Kopaja, who are often shouting the destination as the buses travel along, facilitate these arrangements. The route that a Kopaja bus is following is usually listed on the front window of the bus. But somewhat confusingly, most buses have large garish names plastered across the front window as well such as Mawar, Bunga, Ikhlas, Firdaus and even Sexy. These names, which often tend to obscure other details such as the route number and name, are merely decorations and do not provide information of any particular kind to commuters.
