The Jaya Ancol Circuit was the first automotive circuit in Indonesia. Constructed in 1969 and closed in 1992, it was situated in the Ancol area of North Jakarta. ^[1]

During the circuit's construction, it secured significant sponsorships. Companies including Astra and PT Indocement contributed Rp. 30 million to the construction of the circut. Tinton Soeprapto, a racer and the father of national racers Ananda Mikola and Moreno Soeprapto, was appointed as the mascot of the circut by Ali Sadikin, then governor of Jakarta. This was aimed to attract more international racers to the circuit. The circuit underwent several renovations during its lifetime.

In October 1969, the Jaya Ancol Race I event took place on what was then a residential road with uneven bends. The circuit width ranged from 7 to 10.5 m (23 to 34 ft) wide and had a length of 3.590 km (2.231 mi). In October 1970, the Jaya Ancol Race II was held, with the circuit length extended to 3.950 km (2.454 mi) meters and the number of corners increased to 12.^[2]

In 1971, the Ancol circuit underwent a complete renovation costing approximately 400 million rupiah. The funds were used for hot mix asphalting and the construction of the paddock, pit, and control tower. The paddock included three rooms measuring 150 m × 12 m, 75 m × 12 m, and 51 m × 5 m, accommodating up to 100 cars or 150 racing motorbikes along with their equipment. The pit area had space for 30 racing cars or 50 racing motorbikes, with room for two pit crews per vehicle. The control tower had three floors: the top floor housed the scoreboard and TV and was used by journalists and police; the first floor contained the race control room and facilities for doctors and flag marshals; the second floor was dedicated to timekeeping and served as the office for the competition committee.

The circuit layout, similar to an urban circuit, featured a dominant straight line combined with broken corners. Due to developmental delays in Jakarta in the 1970s, the circuit consisted of simple asphalt roads in a meadow. The lack of construction around the circuit allowed the racer's paddock to be located underneath a tree. After the 1971 renovations, the circuit adopted an L shape, similar to the Salzburgring and Lakeside Circuit.

The track was 4.470 km (2.778 mi) long, with a straight line passing the Duta Toradja restaurant along 1.070 km (0.665 mi). The road width was increased to 9 and 12 m (30 and 39 ft), with a minimum of 10 m (33 ft) and a maximum of 18 m (59 ft) after considering security. International events held at the circuit included the Ancol Grand Prix and Ancol 7-hour endurance race. PT. Astra, with Tom's Japan, developed the Toyota Starlet KP47 and Toyota Corolla KE30 specifically for this circuit.^{[citation needed]}

In 1976, the first Indonesian Grand Prix was held at the Ancol circuit.

The Jaya Ancol Circuit was originally managed by BPP Ancol, once held by Herman Sarens Soediro, and Tinton Soeprapto assumed management in 1983. Governor Soeprapto sent an order to the Chairman of the Indonesian Motor Association (IMI), then held by Hutomo Mandala Putra.

The Ancol circuit, originally 40 ha (99 acres), gradually decreased in size to 12 ha (30 acres). Due to noise and pollution complaints from residents of adjacent elite housing and damage to facilities, the Jaya Ancol Circuit closed in 1992. It was replaced by the Sentul Circuit in Bogor, 40 km (25 mi) south of Jakarta.

The remains of the circuit are now used as an access road for Jaya Ancol theme park, and the southern loop is occupied by a highway interchange. The new Jakarta International e-Prix Circuit is adjacent to the former site of the north loop.
