Abstract

In this article, an in-depth study of the secrets of creation of the Moon in the Quran is presented in relation to the calendar (taqwîm). As you know, the Moon has a regular path by which humans can know the number of the moon, because it rotates, starts from one point and returns to the same point. So, it can be taken a conclusion that with the condition of the Moon evolving towards the Earth with a regular trajectory, humans can calculate it so that it can be used for calendar purposes.Keywords: Al-Quran, calendar, month

Abstract

Among human needs that are not as important as other primary needs is the need for calendars or commonly called calendars or dates. Calendar is a system of organizing units of time, for the purpose of marking and calculating time in the long run. Ancient Egypt had deep-rooted beliefs in dating, that is, through the routines of the niles floods every year, which coincided with the emergence of sirirus stars in the east. The first dating system on this earth was the ancient Egyptian calendar system. The Egyptians first divided the day 24 hours, 12 hours for noon and 12 hours for night time.Keywords: Ancient Egypt, Calendar System, Season.

Abstract

The fact that the Koran is a divine word, has always been a magnet in itself for Muslims to always explore Gods guidance in it. Scholars and scientists from various disciplines in every age have read it from various aspects. However, the Koran always proves that he will not be discussed by humans, not bound by place and time. One feature of reading the Koran is the interpretation approach. Interpretation itself has many features, ranging from analytical, thematic interpretations, seen from the aspects of fiqh, language, science, and so on.Keyword: Text, Context, Verses of Reckoning, Muhammadiyah.

Abstract

Determination of prayer times using calculations and formulas. All times of prayer used in ordinary calculations generally use data when the position of the angle when the sun is in the zenith or when the sun is (entering) zuhur time. This value in the manual calculation is used for each calculation of prayer times at other times with the existing value argument not changing significantly, but in reality the sun position data (sun declination) will be different in value every time even though the data value only changes after 0, 1 point in a certain range, but this shows that the accuracy of declination data is needed on each count to get the value of prayer times which reaches the highest accuracy. Retrieving real time data on the position of the sun when entering criteria is also needed to obtain the truth in the basis of calculating high accuracy local prayer times. In addition, the use of time which is uni (same) must also be agreed upon so that the initial entry time can also be simultaneously. In the use of the application of the prayer time count and also in the book reference, it also has different values and criteria in the calculation, so that the user must also understand the parameters used in calculating prayer times so that he can use a calculation tool that is in accordance with the agreed criteria.

In this study, it was explained that the differences in the results of the calculation of prayer time schedules in North Sumatra were caused by several factors including differences in data used such as: coordinates, sun declination, equation of time, solar height, energy and factors caused by regional time correction, such as differences between Prayer time schedule in Labuhan Batu Selatan regency is calculated using the location of the place, with the prayer time schedule in Labusel Regency counted using Regional Time Correction with Medan City markaz (-5 minutes).Keywords: Differences, Prayer Times.

Abstract

The issue of the initial stipulation of the month (especially Ramadan, Shawwal and Zulhijah) in Indonesia to this day has not ended. One reason for the problem of defining the new moon. Admittedly in Indonesia there are a variety of views and opinions regarding the definition of the new moon which between one another seems contradictory. Nahdlatul Ulama defines the hilal to be visible (ruukyat), Muhammadiyah defines enough by reckoning, and the Ministry of Religion (Government) defines the possibility of being seen (let rukyat). Each of these views has advantages and disadvantages, and each of them has a syaris basic foundation and their respective knowledge.Keywords: Hilal, Beginning of The Month, Reckoning

Abstract

Determination of the beginning of the lunar month in Islam begins with the appearance of the new moon, which is an issue of ijtihad. Based on research shows that in rukyat there are many weaknesses so that this method needs to be elaborated with modern technology (in this case reckoning). Research and calculations carried out by experts on reckoning show that the data generated has always provided very accurate results without leaving significant differences. Basically, Reckoning is a scientific building, so it is strongly influenced by each epistemic discourse. Wujudul hilal carried by Muhammadiyah and imkanur rukyat by the Government has its own characteristics. So, the limit of equilibrium (read: balance) reckoning and imkanur rukyat lies in the extent to which the two communicate with each other, rather than taking distance.Keywords: Early Month, Reckoning, Rukyat, Matlak

Abstract

Kalender Islam Global berfungsi untuk mewujudkan kesatuan umat dengan kalender yang unifikatif secara global dan meminimalisasi terjadinya perbedaan antar negara dalam pelaksanaan ibadah berdasarkan penentuan awal bulan hijriyah. Kenyataannya bahwa peradaban Islam yang berusia hampir 1,5 milenium hingga hari ini belum memiliki suatu sistem kalender pemersatu yang akurat. Di dalam perkembangannya ada banyak kriteria kalender yang diusulkan dalam pertemuan tingkat dunia  untuk menjadi Kalender Hijriyah Internasional dan pada penelitian ini akan fokus pada aplikasi dua kriteria yaitu Kriteria Kalender Islam Global Muktamar Turki 2016 dan Rekomendasi Jakarta 2017 didalam penelitian ini menyimpulkan bahwa Kriteria Rekomendasi Jakarta 2017 tidak dapat mewujudkan kesatuan umat dengan kalender yang unifikatif secara global yaitu kalender dengan prinsip satu hari satu tanggal diseluruh dunia sebagaimana yang telah disepakati dalam Kongres Internasional Kesatuan Kalender 2016 di Istanbul Turki dan tidak dapat meminimalisasi terjadinya perbedaan antar negara dalam pelaksanaan ibadah berdasarkan penentuan awal bulan hijriyah.Keyword: Aplikasi, Kriteria, Kalender Islam Global.
