Abstract

Astronomical phenomenon occur for only a limited amount of time. Observing these phenomenon requires competent promoters and appropriate instruments. The field of view is one of the things that needs to be clearly known so that the observation can take place properly. In this study, joint observations were made between IAIN Lhokseumawe Falak Science Study Programme and OIF UMSU in Medan and Barus. The instruments used in these observations are different, resulting in a variety of fields of view and calculations are needed to get a description of the results. This study aims to calculate the field of view and visibility of the observed phenomenon, the conjunction of the Moon - Jupiter. The results obtained are for the instrument used by IAIN Lhokseumawe Falak Science Study Program at Malikussaleh Observatory has a field of view of 2°7'46.13‘ × 1°25'22.25’, the instrument used by UMSU Medan Falak Science Observatory has a field of view of 1°8'26.96‘ × 0°54'45.57’, and the instrument used by the OIF UMSU Barus team has a field of view of 1°0'43.74’ × 0°41'1.98. Using this combination of instruments cannot observe the conjunction phenomenon, because the elongation of the Moon - Jupiter at the time of the observation is >4°, so to be able to get the visibility of the phenomenon in 1 image requires an instrument that produces a field of view of ~5°.

Abstract

Muhammadiyah as a tajdid (renewal) movement will continue to improve the system in determining the beginning of hijri month through studies, discussions seminars, and research so that the methods and criteria used are truly following the Qur’an, hadith and the Muslims needs in the world. This research purpose to analyze, explore, and discover the transformation and changes in methods made by Muhammadiyah to determine the new month. The research method in this study is a literature study, by conducting a study and book analysis, journals, Suara Muhammadiyah magazines, and related references that have a close relationship with the studies. Based on the study, it shows that Muhammadiyah has made several transformations in its ijtihad to determine the beginning of the new hijri month, starting from the hisab imkanur rukyat sytem, then replaced with the hisab ijtima’ qabl al-ghurub, and the last one was perfected with the hisab wujudul hilal.

Abstract

Astronomi lahir dari kebutuhan masyarakat dalam pencarian penanda waktu dan arah. Namun, masyarakat sendiri belum banyak yang mengenal fenomena astronomi dan cenderung lupa bahkan tidak mengetahui tentang fenomena tersebut. Upaya mengenalkan astronomi kepada masyarakat merupakan salah satu solusi yang dilakukan oleh peneliti yang bekerjasama dengan OIF UMSU masih sebatas di sekolah dilakukan dengan memanfaatkan Program OIF Goes to School di Kota Medan. Program yang dilakukan adalah Sosialisasi dan mengedukasi masyarakat tentang fenomena astronomi, pengamatan matahari dengan teleskop dan kacamata matahari, serta instrumen Astronomi lainnya yang dibawa saat kegiatan berlangsung. Dari program yang dilakukan, masyarakat memberi respon melalui kuisioner dengan skala likert. Respon masyarakat sangat baik, dengan nilai rata-rata sebesar 3,71. Sebanyak 96% responden menyatakan perlu selalu diadakan kegiatan ini kembali.
