Astronomy in Islam (Ilmu Falak) is a branch of science that studies the position of celestial bodies related to the implementation of Islamic worship, especially in determining the qibla direction and prayer times. In this simple study, an analysis was conducted on several mosques, namely Masjid Al-Huda, Masjid Bahrul Ulum, Masjid Besar Al-Muslimun Kepatihan, and Masjid several Besar Al-Falah Ngunut. The analysis was carried out by comparing the qibla azimuth with the direction of the building or prayer rows, as well as evaluating the suitability of prayer times used by the mosques with digital standard times and official prayer schedules. The method used in this study was field observation assisted by digital applications and online prayer schedule sources. The results showed differences in qibla direction deviation and prayer times in each mosque. The largest qibla deviation was found at Masjid Bahrul Ulum, while the smallest deviation was found at Masjid Besar Al-Muslimun Kepatihan. Meanwhile, the prayer time differences ranged from 1 minute to 1 minute 30 seconds. From these results, it can be understood that accuracy in determining the qibla direction and prayer times is very important to support the proper implementation of worship. In addition, the development of digital technology greatly assists the process of falak analysis in modern society.
