Sundial Dalam Sejarah Dan Konsep Aplikasinya Elly Uzlifatul Jannah; Elva Imeldatur Rohmah
Al-Marshad: Jurnal Astronomi Islam dan Ilmu-Ilmu Berkaitan Vol 5, No 2 (2019)
Publisher : University of Muhammadiyah Sumatera Utara

Sundial is a device used as a hint of local pseudo-time using the sun, thus producing the shadows of the gnomon. Sundial is the oldest hour and was first used around 3500 BCE. Sundial consists of several types, namely horizontal, vertical, and equatorial Sundial. Each sundial has its own rules in its creation and the concept of its application. The working principle of this clock is by showing the location based on the sun by looking at the shadows of the sun. As one of the timepiece tools, the sundial not only serves as a tool to know the timing only. It has several other functions, such as the season determinant and the direction of Qibla. However, the entire function of the sundial can only function with the help of the sun as its appointment. By application and the theory, sundial has an excess compared to the math clock. This is because the routine of worship and human social activity is absolutely determined by the time of the Sun standard, not the clock. Because the clock is just the average calculation of the sun's circulation averages around the earth, so the clock can not show the actual time. The sundial can also be used as a time-to-date verifier, as well as a prayer time guideline without time correction, such as digital clock or analog clock.

This writing deals with Islamic International Calendar from the perspective of shariah objectives. Representing one of the most important parts of the Islamic Legal Theory (Uṣūl al-Fiqh), shariah maqasid are discussed widely in the modern times, both concerning their doctrines as well as their application in dealing with other matters of shariah. After clarifying the meaning of shariah objectives and Islamic International Calendar including its concept, principles, qualifications, and parameters, the writer proceed to examine some questions such as is there any objective in shariah doctrines regarding calendar, if the answer is positive what kind of calendars is in line with shariah objebtives and does phisical seeing of the moon represent one of shariah maqāṣid? The writer comes to several conclusions one of which is that, in general, Islamic International Calendar has a close relation to Islamic law objectives.

Publisher : University of Muhammadiyah Sumatera Utara

The Global Islamic Calendar doesn't yet exist because it cannot be applied in some Muslim countries in the world. The criteria for Global Islamic Calendar still debated because it’s difficult to apply throughout the world. The development of information technology encouraged astronomers to digitize the site-based global Islamic calendar. Some websites that we have researched have not yet used the integrated calendar criteria set in Turkey Congress 2016. Therefore it is necessary to maping a website that presents a global Islamic calendar so that it can be used as a reference recommendation for Muslim community.

Publisher : University of Muhammadiyah Sumatera Utara

Now, astronomical observations including hilal observations are easier and simpler because of instruments equiped with computer-based technology. One of them is a telescope that is equipped by a automatical motor drive and computerized. Telescope control is now easier to do with applications based on open source operating systems, one of them is KStars application. With Meade LX-600 telescope owned by the departement of Ilmu Falak, Islamic Studies and Law Faculty UIN Sunan Ampel Surabaya, a control system was built using the KStars application based on open source, which has the advantage of no need to install additional drivers for connectivity with cables.

Pemanfaatan Metode Moving Average dalam Menentukan Awal Waktu Salat Subuh Menggunakan Sky Quality Meter (SQM) Abu Yazid Raisal; Yudhiakto Pramudya; Okimustava ,; Muchlas ,

Publisher : University of Muhammadiyah Sumatera Utara

The beginning of prayer time is important for Muslims because Islam advocates for prayer at the beginning of time. The beginning of Zuhr, Asar and Maghrib prayer times can be done by looking position of the Sun directly. However, the position of the sun cannot be directly observed to determine the beginning of the Fajr and Isha prayer times, because the Sun is below the horizon. The beginning of the Fajr prayer time can be determined by measuring sky brightness using the Sky Quality Meter (SQM). Many factors can affect SQM in collecting light so that the data is not separated from noise. The use of the moving average method reduces noise, making it easier to determine the beginning of the Fajr prayer time using SQM.

Astronomy is a study of the sky. In the development of astronomy and the development of times in the field of science, many astronomical instruments were found, which were useful in research in the field of astronomy. One of the most popular and cannot be taken from astronomy is the telescope. The beginning of the discovery of the telescope originated from its discovery, and at that time a discovery was made that could be used in observing distant objects known with optical telescopes. The more advanced the development of technology, the telescope was found with a new model that uses elekromagnektik waves obtained from radio waves, this telescope is known as a radio telescope.

Effect of Geographical Environment on Success Rate of Rukyat Hilal at Observatorium CASA Assalam Machzumy .
Al-Marshad: Jurnal Astronomi Islam dan Ilmu-Ilmu Berkaitan Vol 5, No 2 (2019)
Publisher : University of Muhammadiyah Sumatera Utara

Rukyat hilal at the beginning of the month of Qamariah, especially the beginning of Ramadan, and Shawwal is a study of celestial spells which often attract attention because of the frequent differences. This dilator is behind the uncertainty of the rukyat results due to the lack of observable rukyat results. This is partly due to the location of the rukyat which is not yet safe enough from various natural disturbances, such as the geographical environment of the observatory. CASA Assalam Observatory is one of the locations designated by the government as a place to report rukyat results. CASA Assalam Observatory located in the middle of Surakarta city, with a height of 144 mdpl, and is 69 km from the sea. But from 5 years of observation of the new moon, only one time succeeded in destroying the hilal. The research method uses descriptive analytical methods, collecting data by means of documentation and direct observation. The results of this study found that one of the causes of the low success rate of rukyatul hilal in the observatory was because the observatory environment located in urban areas was disturbed by the number of buildings, air pollution and light pollution.

Standar Operasional Prosedur (SOP) Kalibrasi Arah Kiblat Masjid di Era Digital I . Ismail
Al-Marshad: Jurnal Astronomi Islam dan Ilmu-Ilmu Berkaitan Vol 5, No 1 (2019)
Publisher : University of Muhammadiyah Sumatera Utara

This paper tries to explain the ideal standard in conducting calibration in Qibla direction by referring to social problems in the digital era. In the digital era, a reference in carrying out the Qibla direction calibration tasks must be truly socially and scientifically accountable, both in using guidelines or standard operating procedure (SOP), as well as calibration minutes made as a placeholder's grip on Qibla direction calibration. . New problems can occur after the calibration of the Qibla direction is carried out, such as the rejection of the results of the calibration of the Qibla direction by a number of mosque worshipers which can lead to religious splits, most of these rejections come from the social and scientific dimensions that have not been fully fulfilled when the calibration was carried out. To avoid or minimize the occurrence of Muslim comflications after calibrating the direction of the mosque's Qibla, these two elements must be truly considered, namely the element of social and scientific elements

Perhitungan Waktu (Time Calculation) Fenomena Tanpa Bayangan di Kota Sambas Kalimantan Barat Reza Akbar
Al-Marshad: Jurnal Astronomi Islam dan Ilmu-Ilmu Berkaitan Vol 5, No 2 (2019)
Publisher : University of Muhammadiyah Sumatera Utara

The shadow less phenomenon in a city is actually already known by the people in Indonesia. In the City of Sambas, the shadow less phenomenon has not been as popular as in the City of Pontianak. The public perception in general is that phenomenon does not occur in this city, but only in certain cities. This research is a kind of qualitative library research by utilizing secondary data derived from five-year ephemeris data, which are 2019, 2020, 2021, 2022, and 2023. The data collection technique uses documentation techniques derived from ephemeris data which is taken from the Winhisab software. Based on this study, the shadow less phenomenon in the City of Sambas occurs twice a year, in March and September. In March, this phenomenon occurred on the 23rd to 24th or after the vernal equinox. Whereas in September, this phenomenon occurred on the 19th to 20th or before the autumnal equinox. In addition, based on the solar transit time calculation using the mid-WIB time, we get that in September, the time of the shadow less phenomenon in the City of Sambas occurred earlier than March.
