Abstract

Sebagai tempat pengamatan astronomi, Observatorium Ilmu Falak Universitas Muhammadiyah Sumatera Utara (OIF UMSU) membutuhkan kualitas langit malam yang bebas dari polusi cahaya. Atas dasar hal tersebut, penelitian ini melakukan analisa pengaruh polusi cahaya pada kualitas langit astronomis di OIF UMSU (3°34’56’’ LU dan 98°43’18’’ BT). Pengamatan kualitas langit malam dilakukan oleh OIF UMSU dari Februari 2018-Maret 2020 dengan Sky Quality Meter (SQM) fotometer pada arah zenit. Dari 588 hari pengamatan, Kami memperoleh rata-rata kecerlangan langit malam dan kecerlangan langit malam maksimum adalah 16,73 mpdbp dan 18,43 mpdbp. Nilai tersebut memberikan batas magnitudo pengamatan mata telanjang (NELM) masing-masing sebesar 2,86 dan 4,32. Untuk meninjau kontribusi cahaya artifisial pada kualitas langit malam di OIF UMSU, kami meninjau emisi cahaya malam hari dari pengamatan satelit Suomi National Polar-Orbiting Partnership (S-NPP) dengan sensor Visible Infrared Imaging Radiometer Suite (VIIRS) dalam rentang tahun 2018-2020. Emisi cahaya malam hari di Kota Medan menunjukkan peningkatan sebesar 5,51-5,93%/tahun. Hubungan antara kecerlangan langit malam yang menggunakan SQM dan data VIIRS memiliki korelasi lemah dengan R2 = 0.03. Berbagai faktor mempengaruhi lemahnya korelasi tersebut, antara lain nilai kecerlangan langit malam yang dipengaruhi faktor cuaca dan cahaya bulan serta pengamatan kecerlangan langit malam yang hanya berada di satu titik lokasi. Kata kunci: polusi cahaya,kecerlangan langit malam, Sky Quality Meter, VIIRS Day/Night band

Abstract

Crescent observation as one of the practices carried out within the scope of falak science has an escalation in methods to adapt the development of science and technology. The development of crescent observation method has an impact on the observation time. In the past, observing crescent only focused when the sun had set, but now observing crescent can be done since the sun is still above the horizon. OIF UMSU as an institution engaged in the field of falak science also conducts crescent observations every month from noon. On November 25, 2022, OIF Barus Team managed to capture the new moon crescent at noon at 13:49 WIB with an elongation of 18°25'. This observation could maximizing existing instruments to obtain crescent images with smaller elongation.

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

Abstract

This study examines the development and role of falak (Islamic astronomy) manuscripts in Southeast Asia within the context of Islamic historiography and the transmission of knowledge from the Middle East. Scholars from the archipelago studied falak in the Middle East before developing it in their homeland, producing repetitive works to facilitate public understanding. However, limited documentation and a lack of in-depth research hinder a comprehensive understanding of the scholars’ roles in the history of falak. This study explored alternative sources, such as local manuscripts, travel notes, and oral traditions, using a multidisciplinary approach that includes philology, history, and the sociology of knowledge. The method used in this research is the philological method, a scholarly approach used to analyze, assess, and interpret ancient or historical texts, particularly in the context of manuscript studies. One of the research locations is the PEDIR Museum (Banda Aceh), the Manuscript Collection of Tarmidzi Abdul Hamid (Banda Aceh), and the Falak Center of Syaikh Tahir in Penang, Malaysia. The results show that falak science in Southeast Asia developed through networks of scholars connected to the Haramain and Egypt. The dissemination of falak manuscripts occurred through trade, missionary activity, and intellectual exchange, while adaptation to local culture preserved its relevance. The influence of the falak manuscripts in Southeast Asia includes strengthening religious authority, establishing local hisab-rukyat traditions, and playing a strategic role in harmonizing the Islamic calendar. This research confirms that the falak manuscripts are an intellectual heritage that reflects the synergy between science and the religious needs of Southeast Asian Muslim communities, while also serving as an important source for the study of the history of Islamic science in the region.

Abstract

This study aims to investigate the effectiveness of VBA-based PowerPoint as an interactive learning medium to increase interest in learning astronomy. The research design used was a Pre-Experimental Design with a one-group pretest-posttest design. The subjects of this study were 20 second-semester students majoring in Astronomy at the University of Muhammadiyah Sumatera Utara. Research data were collected using a questionnaire designed with a Likert scale. The questionnaire consisted of 18 statements, comprising both positive and negative statements. The data analysis technique used was the Paired Sample T-Test. The results of the study indicated that interactive learning media, based on PowerPoint and utilizing VBA, can increase students' interest in learning basic astronomy. The results of the Paired Sample T-Test showed that the significance value (2-tailed) obtained was 0.000. This result indicates a significant difference in learning interest before and after using the interactive PowerPoint-based VBA learning media. This suggests that the use of interactive PowerPoint-based VBA learning media is effective in enhancing learning interest in basic astronomy education. This finding implies that teachers can adopt PowerPoint enhanced with VBA as a cost-effective and easily accessible tool to stimulate learning interest in complex subjects

Abstract

This research departs from the need to strengthen the scientific basis of the criteria of the Unified Global Hijri Calendar (KHGT), especially the criteria for the height of the hilal 5° and elongation of 8° guided by Muhammadiyah. So far, official documents on the origin of these criteria have not been widely publicized, raising questions among astronomers, astronomers, and religious institutions. The main objective of the study was to explain the mathematical analysis behind the selection of the 5° + 8° parameters. The research method was carried out with a theoretical approach using basic astronomical equations to analyze the moon's height, elongation, and azimuth difference, as well as assess its correlation with the possible visibility of the hilal. The results of this study show that the minimum hilal height of 5° and the minimum elongation of 8° have a strong scientific foundation, and do not appear arbitrarily, but are closely related to Bruin's theoretical analysis in 1977 which mapped the relationship between the height of the Moon, ARCV, the depression of the Sun, the width of the moon while the elongation parameter of 8° has a strong correlation with the theory of the visibility limit of the hilal proposed by André Danjon in 1936 the determination of 8° elongation in the KHGT can be It is understood as a form of scientific refinement that combines the theoretical limits of Danjon with an approach to optimal visibility of Bruin's analysis.
