Abstract

This study discusses a comparison of the determination of 1 Shawwal in Thailand and Indonesia, focusing on the methodology used, the role of religious authorities, and the social implications that arise. This research is a literature review with a qualitative approach. Data was collected through literary studies and documentation, then the data was analyzed in a comparative descriptive manner. The results of the study show that although the rukyat and hisab methods are used in both countries, the implementation is different. In Indonesia, the decision to determine 1 Shawwal is carried out through an isbat session involving various Islamic organizations, while in Thailand, the Sheikhul Islam Office has full authority in the determination. These differences affect social dynamics, with Indonesia experiencing differences in celebration times between mass organizations, while in Thailand, centralized decisions result in uniformity. These findings provide insight into how the methodology and structure of religious authority affect the religious practices and social relations of Muslims in both countries

Abstract

This article is the result of research related to the Calculation of Refractive Correction in Determining the Height of the Sun at the Beginning of the Asar Prayer Time" This research is a Research and Development approach research, by producing a product in the form of a refractive calculation for the height of the Sun at the beginning of the Asar prayer time. The primary data source used is the article Impact of Atmospheric Refraction on Asr Time by Abdurrahman Ozlen, the book Mechanics of Celestial Bodies. The method of data collection in this study is documentation. The data analysis method used in this study is qualitative descriptive analysis, which is obtained from the results of the refractive correction calculation in determining the height of the Sun at the beginning of the Asr prayer time. The results of this study conclude. First, the calculation of the refractive correction in determining the height of the Sun at the beginning of the Asar prayer time is to calculate the angle of the Sun's height that appears at the time of the Sun reaches the culmination point, then calculate the height of the Sun visible at the beginning of the Asar time, calculate the height of the true Sun at the beginning of the Asar time which has been corrected by refraction, and finally is to calculate the entry of the beginning of the Asar prayer time

Abstract

This research is motivated by the existing differences in determining the beginning of the lunar month, particularly regarding the timing and location of crescent moon (hilal) observation. The study aims to examine Abdurrahman Özlem’s thoughts on the determination of the beginning of the lunar month and to analyze them from both astronomical and Islamic jurisprudential (fiqh) perspectives. The method used is library research with a descriptive qualitative approach. The primary data consists of Abdurrahman Özlem’s ideas, while secondary data includes books, journals, articles, and other related sources. Data collection was carried out through literature documentation and digital interviews via email. The results of the study show that Abdurrahman Özlem employs the concept of the International Lunar Month Line (ILML) dynamically based on zonal visibility of the crescent moon according to URCUN criteria. In the calculation method (hisab), Özlem uses a minimum elongation criterion of 8° and a minimum altitude of 5°, with the visual observation (rukyat) serving as a verification of the calculation. Astronomically, the ILML divides Earth's regions based on the potential visibility of the crescent moon. From the fiqh perspective, Özlem considers hisab equivalent to rukyat bil ‘ilmi, that is, crescent observation based on scientific calculations. This opinion is supported by several Islamic scholars who allow the use of astronomical calculations in determining the beginning of the lunar month.

Abstract

This article aims to explain the process of constructing a horizontal sundial with criteria suitable for use in tropical latitudes or regions near the imaginary equator line, specifically in the Surabaya area; and to describe the results of measuring the sundial's criteria through testing based on the local digital time. This research is a type of R&D study using a qualitative approach. The techniques employed include observation, documentation, and experimentation. The primary data source used by the researcher is the gnomon’s shadow exposed to sunlight, while secondary data sources include books, scientific papers, latitude-longitude data, and websites containing information on horizontal sundials. The study found four minimum size measurements based on the technique of adapting the horizontal sundial to subtropical latitudes, with the smallest minimum diameter being 89.974 cm. By using this minimum precision standard, the horizontal sundial’s accuracy increases compared to using sundials with a diameter smaller than the stated size. The larger the horizontal sundial size in tropical latitudes, the greater the impact on its accuracy. Conversely, smaller horizontal sundials in tropical latitudes result in decreased accuracy, with the 89.974 cm diameter serving as a minimum reference for the Surabaya latitude.

Abstract

The methods for determining the qibla direction have developed significantly over time, with many easy and practical instruments now available. These include qibla azimuth calculations, raṣd al-qiblah (qibla observation), compasses, theodolites, mizwala, Google Earth, qiblalocator, and various smartphone-based applications. This study focuses on analyzing the methods for determining the qibla direction and the level of accuracy of the qibla orientation of mosques in Prayungan Village, Sawoo, Ponorogo, based on the theories of local raṣd al-qiblah and Google Earth. This research is a field study using qualitative methods. Data collection techniques include observation and interviews. The author selected four mosques as research samples. The results reveal that two of the four sampled mosques did not use methods from the science of astronomy. Their qibla direction determination relied on village access roads and compasses with unknown levels of accuracy. Meanwhile, the other two mosques used methods based on astronomical studies, namely global raṣd al-qiblah and the theodolite. This significantly influenced the accuracy tests conducted using the local raṣd al-qiblah method and Google Earth. Two out of four mosques, including one that used the global raṣd al-qiblah method, still showed deviations in their qibla direction, while the other two mosques showed no deviation
