Abstract

The community often faces problems and problems related to the worship of Muslims, Muslims are also required to carry out obligations that are important factors in the Islamic religion, especially the obligation of prayer that leads to the Kakbah. So far, the measurement of the direction of the Qibla in most methods always uses the Sun, the Sun is one of the celestial bodies that can be used as a reference to measure the direction of the Qibla either in the shadow of the Sun or the azimuth of the Sun. In this case, the author wants to test using the azimuth of the full moon, because there are still many who do not know that the measurement of the direction of the Qibla can not only be with the Sun but can also use the Moon. To find out the extent of the accuracy of the results of measuring the direction of the Qibla with the azimuth of the Moon, the authors formulated several research questions. 1 what is the technique of measuring the direction of the qibla using the azimuth of the full moon? 2 what is the accuracy of qibla direction using the azimuth of the full moon? To answer the research question, the author uses a qualitative research method with an astronomical approach, the primary data used are in the form of trial results of measuring the direction of the Qibla during the full Moon, namely the night of the 14th, and 16th which is marked with a lunar illumination value above 95 percent, and night 15 which is marked with a Lunar illumination value of 100 percent. on the first day obtained a value difference of 00° 03' 50", on the second day obtained a difference in value of 0° 02' 20 and on the third day obtained a difference in value of 0° 02' 12 The collected data were analyzed by descriptive analysis method. The results of the study can be concluded that the technique of measuring the direction of the Qibla using the azimuth of the full Moon is the same as the technique of measuring the direction of the Qibla by using the azimuth of the Sun. Meanwhile, the accuracy is still very accurate, where the results of the trial measurement of the direction of the Qibla by using the azimuth of the full Moon only have an average difference of 00 ° 02ʼ 12 " arc from the results of measuring the direction of the Qibla using the Azimuth of the Sun.

Abstract

Masyarakat sering menghadapi persoalan dan permasalahan yang berkaitan dengan peribadatan umat Islam, umat Islam juga dituntut untuk malaksanakan kewajiban-kewajiban yang menjadi faktor penting dalam agama Islam terutama kewajiban salat lima waktu yang telah ditentukan waktunya. Matahari merupakan benda langit yang bisa dijadikan acuan untuk menentukan awal waktu salat. Selama ini masyarakat menentukan waktu-waktu salat itu dengan cara melihat bayang-bayang matahari, piringan matahari dan syafaq (twilight). Selama ini masarakat juga hanya melihat keindahan warna langit barat tanpa mengetahui apa saja yang mempengaruhi perbedaan warna langit pada setiap harinya. Dalam hal ini penulis ingin meneliti astronomical twilight, karena penulis sendiri sangat tertarik dan penasaran dengan langit senja astronomical twilight. Untuk mengetahui pengaruh warna dan keakurasian astronomical twilight, tujuan penelitian ini adalah untuk mengetahui apa saja yang mempengaruhi astronomical twilight dalam menentukan awal waktu salat Isya, untuk mengetahui bagaimana keakuratan astronomical twilight dalam menentukan awal waktu salat Isya. Dalam penelitian ini penulis menggunakan metode penelitian kualitatif dengan pendekatan astronomi, data primer yang digunakan berupa hasil dokumentasi foto langit barat pada tanggal 18, 20, 21, 22 dan 23 Mei 2022 dan hasil wawancara kepala BMKG Lhokseumawe. Data yang dikumpulkan lalu dianalisis dengan metode deskriptif analisis. Hasil penelitian dapat disimpulkan bahwa terjadinya perbedaan warna setiap harinya sangat dipengaruhi oleh suhu udara, di Lhokseumawe langit sudah benar-benar gelap (astronomical twilight) rata-rata pada pukul 19:33. Sedangkan keakurasiannya di Lhokseumawe astronomical twilight pada tanggal 18, 20, 21, 22, dan 23 Mei 2022 belum bisa dijadikan sebagai patokan awal waktu salat Isya.

Abstract

In the performance of prayer services, a person is required to face towards the Qibla as a valid condition of prayer. The understanding of facing the Qibla must be understood properly and optimally so that efforts to face the Qibla can be done properly and precisely. but for people who are far from Mecca and cannot see the Kaaba directly, the majority of scholars only require facing towards the Kaaba. However, when reviewed, the scholars actually have an agreement that for the person who can see the Kaaba, and the person who cannot see the Kaaba but in fact he can have faith to know the direction to the Kaaba. This research tried to find the opinion of jungka Gajah scholars about the law of observing the qibla for those far from the Kaaba and the limits of tolerance for the direction of qibla for people far from the Kaaba. This research tried to find the opinion of jungka Gajah scholars about the law of observing the qibla for those far from the Kaaba and the limits of tolerance for the direction of qibla for people far from the Kaaba. This research is empirical research using a qualitative approach. With data obtained from interviews with religious leaders Jungka Gajah North Aceh. The data obtained using interview techniques and literature studies, then descriptive analysis with stages of reduction and verification. The results of the research obtained showed: Religious leader Jungka Gajah said that the law confronts the direction of the Qibla when the legal prayer is mandatory, if the person can see the kaaba directly, it is mandatory to face the 'ainul Kaaba when praying. And for the person who cannot see the kaaba then the person must have faith in determining the correct direction of the Qibla. And can make the mosque as a benchmark for the direction of the Qibla, if the mosque has been calculated the direction of the Qibla by people who are experts in the field. The direction of the Qibla that can still be tolerated is that if the shift is below 2 degrees, it can still be forgiven. Because the shift of 2 degrees when people perform prayers cannot be clearly seen with the naked eye the shift in the body of the person who performs the prayer.

Abstract

The initial determination of the lunar month in Indonesia is carried out by the Ministry of Religion of the Republic of Indonesia as a government representative, with the criteria currently used being a minimum of 2o height of the new moon, 3o of elongation and 8 hours of the new moon's age. Astronomers doubt the results of the sighting without visuals from the new moon, especially when the new moon is too low, while jurists hold on to the testimony of the explorer even though there are no visual results. One of the supporting factors for the visibility of the new moon is the weather. Therefore the author formulates the problem, namely how to determine the beginning of the lunar month according to the Indonesian Ministry of Religion and analysis according to fiqh and astronomy with the study of the Decree of the Minister of Religion (KMA) regarding the determination of the beginning of Ramadan, Shawwal and Zulhijah 1435 H/ 2014 M – 1440 H/ 2019 M. This research includes a qualitative research library. The primary data source for this research is the Decree of the Minister of Religion of the Republic of Indonesia (1 Ramadan, Shawwal and Dzulhijjah) in 1381 H -1440 H / 1962 AD - 2019 AD issued by the Directorate General of Islamic Community Guidance, Ministry of Religion of the Republic of Indonesia, while secondary data sources were obtained from documents , reports, manuscripts and technical instructions that support primary data. The determination of the beginning of the lunar month carried out by the Ministry of Religion of the Republic of Indonesia is one of the government's ijtihad carried out to unite Muslims in Indonesia, the determination through an isbat meeting based on the results of reckoning and verification of the rukyatul hilal which is carried out throughout Indonesia. In fiqh terms, the determination made by the government is in accordance with fiqh principles, including hukm al-hakim ilzan wa yarfa'u al khilaf, tasharruf al-imam 'ala raiyatih manuthun bi al mashlahah, and yattabi' al mashlahah ar raajihah. Astronomically, weather factors such as air temperature, air humidity, rainfall, wind speed and direction support the sighting of the new moon during the sighting.
