Abstract

Performing prayers is an obligation for Muslims wherever they are. The time and direction of the Qibla where they are located on the surface of the earth can certainly be observed and determined normally using both projections and solar shadows. But an obstacle occurs when a Muslim will pray while he is in outer space near the earth such as on the international space station, or other space stations that exist today or in the future, so studies are needed to get a solution to this condition. Ijtihad ulama expressed several opinions such as using a benchmark time from the last location where the Muslim astronaut departed or using the prayer schedule used in Mecca. While facing the Qibla direction, there are four optional references such as facing the Kaaba on Earth in the relative movement of the spacecraft, following the projection of the Kaaba, facing towards the Earth, and facing in all directions based on belief.

Abstract

This article investigates research and publications related to Islamic astronomy, with a focus on Indonesia—the country with the largest Muslim population globally. The study examines scholarly works from Google Scholar over the past nine years (2015-2024), using filters for “astronomi islam” and “Islamic astronomy” using Publish or Perish application. The most frequently researched topics include the Islamic calendar, the new moon, and the Qibla. Surprisingly, despite the growth of Islamic astronomy in Indonesia, the number of studies on these topics has not increased substantially. To advance research, consider exploring automation and robotic systems, creating DIY tools, and leveraging image processing technology, machine learning, and deep learning.

Abstract

According to Surah Al-Baqarah, facing the qibla is a religious requirement in performing salah (prayer). Therefore, the objective of this research is to understand the methods used to determine the qibla direction of Masjid Al-Mujahidin in Parepare and analyze the calibration of its qibla direction. This research employs a qualitative approach with field research methodology. Data analysis is conducted using a descriptive approach to provide an overview of the research object and test hypotheses.  The results of the research indicate that: 1. The method used to determine the qibla direction of Masjid Al-Mujahidin in Parepare is a combination of a compass and observations of the sun's shadow. 2. Calibration of the mosque's qibla direction reveals a deviation of one and a half degrees. Although this deviation is considered small, it can still be tolerated in certain circumstances or within certain parameters.

Abstract

A binary star is a star system that has been studied by astronomers around the world since the 17th century. From the beginning, binary star research used simple methods and tools. However, since the 20th century, computers and programming languages such as Python have been used to study binary stars and their light curves. The development of the Lightcurve Python module is very helpful for people and ordinary people to understand how to use the Lightcurve Analyser in an easy to understand language. There are many tutorials on how to use the Python light curve module on Youtube channels, which can be used for references such as Planet Hunters

Abstract

Determining the beginning of prayer time on the Mount Prau hiking trail is very important for Muslims, especially when performing the five daily prayers. Calculation of the beginning of prayer time is important even though prayers can be performed within a certain time range. This study aims to apply spherical trigonometric calculations and to determine the results of the beginning of prayer time on the Mount Prau hiking trail. This research uses spherical trigonometry hisab method with the required data are latitude of place, longitude of place, solar declination and equation of time. The calculation results show the exact prayer time, such as dawn between 04.24 to 04.29 WIB, zuhur between 11.39 to 11.44 WIB, asar between 15.01 to 15.05 WIB, maghrib between 17.32 to 17.36 WIB and isya between 18.46 to 18.51 WIB. This information is useful for climbers of Mount Prau so that they can carry out worship on time.

Abstract

Determining the beginning of the Hijri month is very important for Muslims, especially in Indonesia. One way to determine the beginning of the month is by observing the new moon or moon sighting. In the process of hilal (crescent) sighting, there are theoretically obstacles related to the validity of the sighting results. By implementing an observation system that has the function of displaying and storing observations through a developed application, it is hoped that it can help to increase the validity of the new moon observation. This study answers two problem formulations, specifically: (1) Can an OpenCV-based new moon observation application be built? (2) Can the multiview function be implemented with OpenCV? By using the Phyton programming language, the OpenCV library, and other additional libraries, an OpenCV-based new moon observation application has been successfully created, and at the same time the Multiview function has been implemented. The used application works well, especially the multiview function and the function to save the observations in the specified image format.

Abstract

Recent technological advancement, artificial intelligence (AI), allows for the integration of human intelligence algorithms and application machines. As AI develops, it will be able to assist people in a variety of areas, including business, health, education, and others. The advantages of AI in establishing the start of the Hijri month are one of the benefits that we will discuss in this paper. Muslims, especially Indonesian Muslims, are now highly interested in learning about the Hijri calendar, especially as the months of Ramadan and Shawwal begin. Community organizations have repeatedly criticized the government's determination of the month's beginning in recent years with some argumentation provided. In order to address this issue, we will attempt to apply AI to pinpoint the start of Islamic Calendar especially in these months. This paper shows that in Fiqh and Astronomical Perspectives, Artificial Intelligence cannot be used as the main instrument in determining the beginning of the Islamic Calendar in Indonesia.

Abstract

Matlak in the determination of the beginning of the Kamariah month of the Majelis Pengkajian Tauhid Tasawuf Indonesia (MPTT-I) is often different from other methods. The conventional rukyat system and the limited scope of matlak are the causes of the dynamics, even in conditions of high hilal visibility differences still occur, the community is confused by this situation. This research is a qualitative research with a scientific approach. Data sources were obtained based on interviews, observation and documentation, with descriptive analysis. The results of this study indicate that; 1) The method of determining the beginning of the Kamariah Month of the Majelis Pengkajian Tauhid Tasawuf Indonesia (MPTT-I) uses conventional rukyatul hilal, with a limit of 32 minutes of sunrise-sunset distance, 2) The implementation of matlak in determining the beginning of the Kamariah Month of the Majelis Pengkajian Tauhid Tasawuf Indonesia (MPTT-I) on the Potential Differences in Fasting and Feast Days in Indonesia is very significant, the application of this matlak has an impact on the impossibility of unification. With the consequence that it will be absolutely different from some methods such as imkanurrukyat with existing criteria.

Abstract

The determination of the start time for Zuhr prayer in its calculation does not refer to the actual natural phenomena but is based on the Sun's transit at the meridian, plus a specific margin of safety (ihtiyath) that differs from the ihtiyath values used for other prayer times. This study demonstrates the duration of the Sun's decline throughout the year to validate the use of this specific ihtiyath for Zuhr. The calculation of the Sun's decline duration uses data on solar declination and semi-diameter, which are then simulated for the entire year of 2025. The simulation results show that the duration of the Sun's decline ranges from 63.64 to 70.85 seconds. When rounding up the duration of the decline and adding an ihtiyath value of 2 minutes (similar to the ihtiyath for other prayer times), the conclusion from this study suggests that the ihtiyath for Zuhr should be 4 minutes. However, it would be better if the calculation of the start time for Zuhr prayer used corrections based on solar declination and semi-diameter data to indicate the actual phenomenon of the start time for Zuhr prayer and to avoid misconceptions by using a uniform ihtiyath for all prayer times.

Abstract

The problem related to the direction of the qibla is becoming more and more inclusive in the current era, considering that the suitability of the direction of the qibla is one of the prerequisites that must be met so that prayer can be considered valid according to sharia. In this Modern Era, there are Qibla directional instruments, both manual and digital-based such as Google Earth and Qibla compasses. In addition, there is also another innovation tool, namely X-Blind Qibla based on a modified compass with the addition of a buzzer. The author tries to examine the accuracy of the X-Blind Qibla with the standardization used, namely the Google Earth calibrator, based on a sample of mosques that have two typologies, namely the mosque that is right to the Qibla and the mosque that leads to the West. The research methodology stated in studying this problem is a qualitative method or field research. Based on the results of the study, it was found that the X-Blind Qibla deviated with an average value in the range of 1° 16' from the measurement results through Google Earth. The factors that affect the deviation are due to the effect of a large magnetic field, so that it has an impact on the movement of the compass magnetic needle. The value of the deviation is still understandable, if the reference in facing the qibla is the state of Saudi Arabia. This means that this tool can be applied in the practice of worship individually, even though it has not yet reached a high level of accuracy.
