One Hijri month comprises 29 or 30 days. There are two methods in calculating the beginning of the islamic lunar month, that is the hisab method and the rukyat method. From both approaches, the term mathla' (area boundaries based on the reach of the new Moon) originates. Mathla' is divided into mathla' ikhtilaf (local mathla') and mathla' ittihad (global mathla'). From the two mathla', there are diverse opinions regarding the use of mathla'. Therefore, the government is present and seeks to avoid this imbalance through imkan ar rukyat. This research involves qualitative research, categorized as library research, described descriptively with systematic, correct explanations and relevant sources. The dialogue on the two mathla' is reaping the pros and downsides among numerous madhhab imams and Muslim personalities. The three madhhab priests believe that global mathla' is the reference for the people, except for the Shafi'i priest. Figures such as Hasbi Ash shiddieqy consider that global mathla 'as a basis for attaining the unity of the ummah. In contrast to Thomas Djamaluddin, Basit Wahid and Yusuf al-Qaradhawi who prefer local mathla' as a reference. This study also examines the application connected to mathla', namely the Islamic Calendar at Turkey's International Hijri Calendar Unity Conference (IHCUC) congress. What has implications or effects if the new moon on one continent has appeared is not necessarily the same on other continents. This happens because the geographical position of the area is different. It gives a favourable critique to establish a shared opinion for the benefit of the people.","PeriodicalId":444196,"journal":{"name":"Al-Hilal: Journal of Islamic Astronomy","volume":"100 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134555054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The observations had two goals: determining the most efficient filter for observing the Penumbral Lunar Eclipse (PLE) and determining the influence of TLE phenomena on sky brightness. The acquired picture data is analyzed using the photometric approach. Six sample points are utilized to calculate the magnitude of the PLE. According to the findings, the blue filter is the generally ideal filter for detecting PLE. Tycho crater had the greatest magnitude of -18.1 while mare Imbrium had the highest magnitude of -17.2. When determining the intensity of the crater and mare, this value is impacted by various parameters, including the duration of the integration period and the aperture radius. As a result, this number still has to be adjusted to the full moon's intensity. The results of SQM measurements of the sky's brightness form a light curve pattern that declines during the umbra phase and continues to diminish until the Moon departs the Earth's penumbra. This shows that the value of sky brightness increases or the sky becomes significantly darker during the total phase, while the Moon's skyglow diminishes during TLE.","PeriodicalId":444196,"journal":{"name":"Al-Hilal: Journal of Islamic Astronomy","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121972392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, zodiacal light is referred to as false dawn (fajar kadzib) or false dusk. Zodiacal light is emitted by the dust leftovers of asteroids, comets, and other extraterrestrial objects colliding along the planet Mercury's orbit to Mars. This remaining material orbits the Sun in the same direction as the four planets. When the Sun illuminates the leftover dust, it appears as a zodiacal light in the hemisphere that experiences dawn or dusk. By using linear fittings we detect the presence of zodiacal light on the light curve of the night skybrightness. The Observations were made using a digital camera and SQM. From a number of observational data obtained at six locations, it shows that there is an identical linear pattern. From this linear model, it can be seen that the zodiacal light has been observed since the sun's position at -60 degrees below the horizon. Recognizing the presence of the zodiacal light is very important to know the time of the appearance of true dawn which is the beginning of the time for the dawn prayer.","PeriodicalId":444196,"journal":{"name":"Al-Hilal: Journal of Islamic Astronomy","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116689489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accuracy of the compass sensor in determining the direction of qibla is still doubtful, because the compass sensor is easily affected by the surrounding magnetic field, and the north direction shown by the compass sensor is not the geographical North direction but the north direction of the Earth's magnetic field. It certainly has a very influential effect on the accuracy of compass sensors in determining the direction of Qibla. The north direction produced by the compass sensor can be converted into the geographical north by adding a magnetic declination correction value. This study aims to analyze the effect of magnetic declination correction on the accuracy of compass sensors on android phones in determining qibla direction. The type of research used is a type of field research with a quantitative approach. In this study, observation was done by comparing the qibla direction of the android compass sensor with the qibla direction of a theodolite.

Especially in the prayer worship. Al-Quran and Hadith have explained about the direction of qibla during the lifetime of the Prophet. The Problems begun when Muslims spread all the world as it is today. Muslims who are far from Mecca can not see the Ka’bah, so it is difficult to determine the \"ainul Ka'bah\". But now the rapid development of technology makes it easy for Muslims to determine the direction of the Qibla appropriately. In this case, however, the ulama' do ijtihad with their fatwa regarding how precisely facing the Qibla is permissible for those who cannot see the Ka'bah. This study aims to explain how 'Indonesian' ulama in this case the Indonesian Ulama Council (MUI) and 'Egyptian' ulama (Dar al-Ifta 'al-Misriyyah) resolve the problem and explain what lies behind the views of both. This study is a comparative normative study using a qualitative approach. The study data was taken from the MUI fatwas and Dar al-Ifta 'al-Misriyyah. The results of the study showed that the MUI fatwa initially decided the direction of the qibla of Indonesian Muslims to face westward, but then a new fatwa emerged afterwards which decided the qibla of Indonesian Muslims to face northwest with varying positions according to the location of their respective regions. In contrast to the MUI fatwa, the fatwa from Dar al-Ifta 'al-Misriyyah shows that for those who cannot see the Kaaba it is permissible to deviate slightly from the actual qibla direction with a 45 degree limit in the right or left direction.","PeriodicalId":444196,"journal":{"name":"Al-Hilal: Journal of Islamic Astronomy","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123744444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
