Abstract

Effective astronomy education requires hands-on experience with modern technological tools and observational practices. This community service project aimed to enhance the pedagogical competencies of science teachers from the Science Teacher Working Group (MGMP IPA) of Grobogan District through comprehensive training in astronomy modeling and observation techniques. The training, conducted on July 17, 2025, at the Planetarium and Observatory of Universitas Islam Negeri Walisongo Semarang, integrated theoretical knowledge with practical applications using professional software and instruments. Participants engaged in interactive seminars featuring astronomical modeling through web-based simulations and specialized software including Stellarium, SpaceEngine, and Cartes du Ciel. The program also included immersive planetarium experiences with 4K dome visualization and hands-on telescope observation sessions. Feedback from 32 participating teachers indicated high satisfaction levels and increased confidence in implementing astronomy education in their classrooms. The collaboration between the educational institution and the teacher working group proved effective in bridging the gap between theoretical astronomy knowledge and practical teaching methodologies. This initiative highlights the critical role of planetariums and observatories in supporting STEM education and suggests the need for continued professional development programs for science educators.

Abstract

The determination of the Islamic lunar month through ru’yat al-hilāl remains contested in Indonesia, particularly when individual testimony conflicts with established visibility criteria (imkān al-ru’yah). This study examines the concept of ḥadīd al-baṣar in the thought of Ibn Ḥajar al-Haytamī and its implications for moon sighting testimony in Indonesia. Using qualitative library research and Fazlur Rahman’s double movement theory, this study reconstructs the historical background of Ibn Ḥajar’s view and contextualizes it within contemporary practice. The findings show that his concept was shaped by Shāfi’ī legal methodology, early astronomical knowledge, and the absence of optical instruments. Testimony based on ḥadīd al-baṣar cannot serve as a general legal basis but may be personally binding. In Indonesia, such testimony is not institutionally accepted when it contradicts official visibility criteria.
