Abstract

Qibla direction application on android phones generally utilizes a compass sensor (magnetic orientation) as a reference to determine the direction and detect qibla direction. The accuracy of the compass sensor in determining the direction of qibla is still doubtful, because the compass sensor is easily affected by the surrounding magnetic field, and the north direction shown by the compass sensor is not the geographical North direction but the north direction of the Earth's magnetic field. It certainly has a very influential effect on the accuracy of compass sensors in determining the direction of Qibla. The north direction produced by the compass sensor can be converted into the geographical north by adding a magnetic declination correction value. This study aims to analyze the effect of magnetic declination correction on the accuracy of compass sensors on android phones in determining qibla direction. The type of research used is a type of field research with a quantitative approach. In this study, observation was done by comparing the qibla direction of the android compass sensor with the qibla direction of a theodolite. The study showed that qibla direction measurement using android compass sensor with magnetic declination correction of angle difference (deviation) of 03° 55' 0.055" or 437.6815289 km, against qibla direction of the theodolite.

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.
