The Continuity of Astrolabe as a Multipurpose Astrofiqh Instrument

摘要

Astrolabe is a device invented during the Greek age and is known as a multifunctional analogue computer used by astronomers and navigators. This research focuses on the historical development of astrolabe through the times beginning from pre-Islamic to the peak of astronomical knowledge in the golden age of the Muslim civilization. The research objective is to study the civilizations, whether Muslim or non-Muslim. This research uses a qualitative approach through the methods of historical study and content analysis, specifically of works by Western and Muslim scholars in the field of astronomy. Research findings argue that the astrolabe is a multipurpose analogue instrument in astronomical computation and observation for civilization after civilization and is the basis for development of digital astronomy after the advent of Islam. Among the functions of the astrolabe is to obtain the precise timing of sunrise and sunset, determine Qibla direction, compute prayer (solah) time schedule and determine the beginning of Hijri months.
