Ilmu Falak
Undergraduate Course, UIN Jurai Siwo Lampung, 2026
Course Overview
Undergraduate course on Ilmu Falak (Islamic Astronomy) and its application to Islamic religious practices.
The course examines the astronomical foundations of qibla direction, prayer times, Hijri calendar determination, hisab and rukyat, crescent visibility, solar and lunar phenomena, celestial coordinates, and observational astronomy.
It also introduces contemporary developments in astronomical instrumentation, digital imaging, and the use of astronomical evidence in Islamic legal reasoning. Through conceptual study, calculation, observation, and practicum activities, students develop an integrated understanding of classical Ilmu Falak and contemporary astronomical methods.

Islamic Astronomy Learning Workflow
1
Astronomical Foundations Earth–Moon–Sun system, celestial sphere, coordinates, apparent motions, horizon, equator, and ecliptic. →
2
Astronomical Calculation Qibla azimuth, prayer times, lunar position, conjunction, elongation, altitude, and related calculations. →
3
Observation Field observation of qibla direction, prayer-time phenomena, crescent visibility, eclipses, and other celestial events. →
4
Digital Imaging Use of telescopes, cameras, CCD/CMOS sensors, astronomical photography, and image documentation. →
5
Quantitative Analysis Image processing, photometric analysis, contrast, sky brightness, and observational data evaluation. →
6
Astronomical Interpretation Evaluate astronomical evidence, visibility criteria, observational uncertainty, and scientific implications. →
7
Islamic Legal Application Relate astronomical evidence to hisab–rukyat, Hijri calendar determination, religious practice, and Islamic legal reasoning. Course Learning Outcomes
By the end of the course, students are expected to be able to:
- Explain the fundamental concepts, scope, historical development, and position of Ilmu Falak within Islamic studies.
- Apply basic astronomical concepts and celestial coordinate systems to problems in Islamic astronomy.
- Calculate and verify qibla direction using spherical astronomy and relevant observational instruments.
- Explain and calculate the astronomical foundations of Islamic prayer times.
- Analyze the principles of Hijri calendar determination, including hisab, rukyat, conjunction, elongation, crescent altitude, and lunar visibility.
- Conduct basic astronomical observations and document crescent, solar, and lunar phenomena systematically.
- Evaluate contemporary crescent-visibility criteria and problems related to Hijri calendar unification.
- Integrate astronomical evidence with Islamic legal reasoning in contemporary Ilmu Falak.
