Abstract

TM. Ali Muda is a North Sumatran astronomy figure who came from Aceh. His work and contribution in the field of astronomy is beyond doubt. His thinking in the matter of determining the beginning of the month is to combine calculations and field observations. However, the tendency of his calculation (hisab) is also quite dominant which is shown by his analysis in various issues of celestial jurisprudence. Meanwhile, in the matter of matlak and Eid al-adha, the hajj-related services whose implementation is only in Mecca, according to him, are obliged to hold on to the matlak of Mecca, while those whose implementation is not only in Mecca are obliged to hold on to their respective matlak

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°.
