A planetarium is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation. The position of the planetarium in an archipelagic country like Indonesia is very important, especially for people in rural areas to get equal rights in obtaining education and access to technology. With a planetarium that is easily accessible, it certainly allows the public to observe celestial objects together and gradually get scientific information to bring them closer to science, especially astronomy, using fun, interesting, and engaging activities. Through this process, the existence of a planetarium has become a potential tool for community building in various regions and even rural areas in Indonesia.
