Make your own cardboard planisphere

Adapted from Dominic Ford

Astronomi dan Masyarakat di Negara Brunei Darussalam

Hazarry bin Haji Ali Ahmad
Persatuan Astronomi Negara Brunei Darussalam
*Presenting author’s email: hazarry@bruneiastronomy.org

Astronomi merupakan suatu bidang yang multidisiplin iaitu gabungan sains, matematik, agama dan pelbagai lagi. Bagaimanapun di Negara Brunei Darussalam pendedahan bidang tersebut terhadap orang ramai masih lagi kurang. Justeru itu, Persatuan Astronomi Negara Brunei Darussalam (PABD) memainkan peranan sebagai agensi bebas dan persatuan bukan Kerajaan untuk memajukan bidang ini terutamanya astronomi Islam (falak syarie) melalui pelbagai inisiatif dan mempelbagai program bagi menarik minat masyarakat. Sejak penubuhan PABD pada tahun 2003, beberapa faktor yang menyumbang serta cabaran pada perkembangan bidang astronomi dalam kalangan masyarakat di Negara Brunei Darussalam telah dikenalpasti.

Abstract

There are various methods used to determine the arrival of Ramadan (fasting) and Syawal in South East Asia. Malaysia and Indonesia use the rukyah (sighting of the moon) and hisab (mathematical calculations), Singapore uses the hisab while Brunei only uses the rukyah method. These differences are due to the different basis for using a certain method to determine the arrival of Ramadan and Syawal. The basis here refers to religious references and forms of istidlal (inferences). The question is, what religious references are used to substantiate the adoption of the rukyah method in Brunei? What is their form of istidlal based on the religious references? To answer all these questions this study has two objectives. Firstly, it intends to determine the religious references that act as the basis for using the rukyah method in Brunei. Secondly, to analyse the different forms of istidlal based on the religious references. In order to achieve these objectives, this qualitative study used library research and expert interview methods for collecting data. All the data were analysed using the content analysis method. Lastly, this study concluded that religious references from the al-Qur’an and Hadith used as a basis for applying the rukyah method in Brunei is similar to the religious references used as a basis for applying rukyah and hisab in other South East Asian countries. The only difference is the various forms of istidlal.

New Criterion for Lunar Crescent Visibility

By MOHAMMAD SH. ODEH, Arab Union for Astronomy and Space Sciences (AUASS), P.O. Box 141568, Amman 11814, Jordan (e-mail: modeh@auass.org) Β (Received 12 May 2005; accepted 19 September 2005)

Abstract. A new criterion for lunar crescent visibility has been established using 737 observations, almost half of them obtained by the Islamic Crescent Observation Project (ICOP). This criterion is based on two variables, viz. the topocentric arc of vision and the topocentric crescent width. The new model is able to predict the visibility of the lunar crescent both for naked eye and optically aided observations. From the database we found a Danjon limit of 6.4 degrees.

Introduction The lunar crescent visibility has been studied by many astronomers since the Babylonian era, with as a result currently more than 12 different criteria for lunar crescent visibility, based on a number of sightings in different lunar conditions. Many of these criteria were developed by Islamic astronomers, since a number of Islamic religiouseventsaredirectlyrelatedtolunarcrescentsighting.Forexample,thenew Lunar (Hijric) month begins on the next day of sighting the new crescent at west after sunset.
