Qibla Direction in Various Coordinates in Indonesia using Spherical Trigonometry
Abstract
Qibla is something very important for Muslims. It is because the Qibla is one of the requirements for performing prayers. As a place that is quite far from the Kaaba, the direction of the Qibla in Indonesia can be determined using spherical trigonometry mathematical equations. This article presents qibla direction in various coordinates in indonesia using spherical trigonometry. The Qibla direction of various coordinates in Indonesia can be a guide in determining the Qibla direction. The direction is calculated using spherical trigonometry. For the results to point directly to the Kaaba, the north direction is very necessary. The true north can be determined using various instruments such as, theodolite, gnomon, or mizwala.
