Abstract

The observatory is a building containing permanently-installed optical equipment used to view and examine celestial bodies or events related to space. The position of Al-Afaq observatory is very important, especially for the Islamic (Falak) science faculty of the Sharia UIN Mataram to improve the skills of students and the community in West Nusa Tenggara, especially for school students from the kindergarten to higher education that has only seen the celestial bodies through photographs, but with the presence of this observatory, they can see the celestial objects in real. The availability of this observatory is a major requirement for the advancement of Science, especially astronomical fiqh that seeks to understand the verses of kauniyah in the Qur’an. So that we can understand the Divine secrets that exist in the Word of God

Abstract

The visibility of the new Moon is significantly influenced by the Sun’s position at Sunset, often referred to as elongation or the angular distance between the Sun and Moon. The criteria currently agreed upon by the Indonesian government for determining the start of the lunar month are the NEW-MABIMS criteria, which require a minimum Moon height of 3° and a minimum crescent elongation of 6,4°. This thesis aims to (1) determine the influence of elongation and lunar illumination fraction on the visibility of the new Moon, and (2) identify the elongation value and lunar illumination fraction that impact the new Moon’s visibility at Loang Baloq Beach. This research employs a field research method using a mixed-methods approach. Data collection methods include observation and documentation. The result of this thesis indicates that (1) both elongation and lunar position fraction affect the visibility of the new Moon.  Multiple linear regression analysis, a correlation value of 68,41%, categorized as strong, a coefficient value of 41,96%, categorized as moderate and R2 46,8% also categorized as moderate. This suggests a significant influence of elongation and lunar illumination fraction on the visibility of the crescent Moon, though other factors also contribute. (2) the smallest crescent observed was at the elongation of 8° 11’ 24.00” with an illumination fraction of 0,69%. This record serves as the minimum elongation and illumination fraction values impacting new Moon visibility at Loang Baloq Beach over the last three years. In general, the greater the elongation, the larger the illumination fraction, indicating that as the Sun’s distance from the Moon increases, the visibility of the illuminated portion of the Moon also increases.
