Jakarta Planetarium and Observatory (Indonesian: Planetarium dan Observatorium Jakarta) is a public planetarium and an observatory, part of the Taman Ismail Marzuki art and science complex in Jakarta, Indonesia. The planetarium is the oldest of the three planetaria in Indonesia. The second planetarium is located in Surabaya, East Java. The third planetarium is located in Kutai, East Kalimantan.
Construction of the planetarium was an initiative of President Sukarno when in the early 1960s he envisaged a monumental large-scaled planetarium project. However, by the next half of the 1960s, the design was made more modest. The construction of Jakarta Planetarium and Observatory began in 1964 as part of the construction of the Taman Ismail Marzuki art complex. The construction was funded by the Indonesian government and the Indonesian Batik Cooperatives Association (Gabungan Koperasi Batik Indonesia or GKBI).
The 22 meter dome of the planetarium was completed in 1968. On November 10, 1968, the building was officially inaugurated by the Governor of Jakarta Ali Sadikin together with the Taman Ismail Marzuki art complex. The planetarium was opened to public on March 1, 1969; the day was made the official birthday of the planetarium. The planetarium made use of the Carl Zeiss Universal planetarium projector
In 1975, a coudé telescope that was already a property of the institution since the 1964s was installed in a two-floored building not far from the planetarium. In 1982, the coudé telescope was moved closer to the present observatory because the land where the telescope stands earlier belongs to another owner.
In 1984, Jakarta Planetarium became officially the Jakarta Planetarium and Observatory. In 1991, the building was extended and facilities such as class rooms, were added. In 1994, a 31 cm star telescope was acquired to replace the older telescope.
Major renovation and technological upgrade of the planetarium was done in 1996. The previous Universal Projector was replaced with the computerized Universarium VIII Projector. The material for the domed screen was replaced and the diameter of the dome was reduced from 23 meter to 22 meter. The floor was elevated and terraced. The previous central-facing seating configuration was reorganized into a south facing configuration, and the amount of seats was reduced from 500 to 320.
