Understanding the effect of revolution and rotation of the earth on prayer times using accurate times

Abstract: Prayer time is closely related to the position of the Sun toward the Earth. The position of the Sun against the Earth is affected by the revolution and rotation of the Earth.

Kemiringan maksimum sumbu rotasi bumi terhadap bidang ekliptika adalah sebesar 23,5° (Raisal & Rakhmadi, 2020). Dinamika kemiringan sumbu rotasi ini menyebabkan terjadinya gerak semu matahari .…”

Untuk menghitung waktu salat subuh sesuai dengan ketinggian matahari, digunakan rumus yang diturunkan dari persamaan Segitiga Bola(Karttunen, H., Kröger, P., Oja, H., Poutanen, 2016).…”
