Abstract

One of the methods in measuring Qibla Direction is using a compass. The compass itself consists of various types and has different levels of accuracy. Therefore this trial was conducted to determine the level of accuracy between the Brunton compass and the Suunto compass in measuring Qibla direction. This research method uses the field research method or field research using the Brunton Compass, Suunto Compass, Theodolite, Arc Roller, Solar Azimuth Data, Magnetic Deviation Data for Medan City and other supporting data/instruments. The results of this study indicate that the Brunton compass has higher accuracy than the Suunto compass which was tested using a theodolite.

Abstract

Waktu salat Subuh dimulai ketika terbit fajar shadiq dan berakhir sampai terbit Matahari. Di Indonesia banyak ahli falak yang menetapkan kriteria ketinggian Matahari untuk menentukan awal waktu salat Subuh dengan ketinggian yang bervariatif, mulai dari -18 derajat sampai -20 derajat di bawah ufuk bahkan pada ketinggian -13 derajat di bawah ufuk. Kementerian Agama RI menetapkan ketinggian Matahari untuk waktu salat Subuh pada -20 derajat di bawah ufuk. Dengan adanya perbedaan dalam menetapkan ketinggian Matahari di bawah ufuk, para ahli falak maupun astronomi banyak melakukan pengamatan ulang terhadap kemunculan fajar shadiq. Salah satunya melakukan pengamatan fajar shadiq menggunakan All Sky Camera dengan metode moving average dan pendekatan Gradien. Penelitian ini merupakan penelitian kuantitatif dengan pendekatan (field Research) melalui observasi untuk mendapatkan data dilapangan secara langsung. Berdasarkan penelitian yang dilakukan didapatkan kemunculan fajar shadiq pada saat ketinggian Matahari pada -15 derajat di bawah ufuk.

Abstract

For a long time, Muslims were facing problems related to the determination of the Tarwiyah and the Arafat fasting day. In this case, whether Muslims should follow the Saudi Arabian calendar or the local one. In this study, Muslims differ in opinion, some argue that they should follow the Saudi Arabia calendar and others say that enough to follow the national calendar. The absence of unified calendar resulted in many problems faced by Muslims in assigning their holidays such as Ramadan, Shawwal, and Dhulhijah. To achieve Muslim unification in conducting various religious rituals, Muslims must have a unification dating system in order to realize togetherness in determining the worshipping time. This research is literature research. Thus the data that used in the form of books, journals, and other references. The results concluded that the determination of Tarwiyah and f Arafat Day until now still provides dispute among Muslims, there are those who argue specifically in determining the Dhulhijah beginning must be oriented to the Saudi Arabia kingdom’s determination. While others argue that assigning the worshipping time does not have to follow Saudi Arabia, just adhering to the nation’s determination
