<![CDATA[The determination of prayer times initially only used the direct observation method (rukyat) namely observing the shadow of an object, then the determination of prayer times developed with the advent of the calculation method (hisab). The purpose of this study is to make a simulation of the calculation of prayer times using a spreadsheet. A simulation of the calculation of prayer times using a spreadsheet has been made. The prayer times generated by the spreadsheet are not much different from the prayer times obtained from the Accurate Times application. The simulation that has been made can show the effect of the Earth's revolution at prayer times at various latitudes.]]>

<![CDATA[Astronomy learning is often considered difficult by most students of the Astronomy study program at the Universitas Muhammadiyah Sumatera Utara., so effective learning media in the form of digital comics is needed. This type of research is research and development (R&D), which follows the ADDIE (Analyze, Design, Development, Implementation, Evaluation) development procedure. This research is only limited to the development stage. Comics are developed using Canva because they are easy to use on all devices and provide many features that make it easy for users to create graphic designs. The validation results from media and material experts on the comics developed each have an average value of 91% and 92% or are included in the very good criteria. These results indicate that digital astronomy comics can be used in learning. This research is limited to the development stage, so its effectiveness in learning cannot be known. The effectiveness and practicality of this digital astronomy comic can be known through the implementation stage.]]>

<![CDATA[This research aims to improve students' literacy and numeracy skills in Namanjahe Village through the utilization of print and social media. The approach used is participatory action research, where researchers are directly involved in activities to address the educational challenges faced by students. Based on interviews and observations, several issues were identified, such as low literacy rates, limited use of educational technology, and a pragmatic mindset that hinders mathematical thinking. The action plan includes introducing print media and social media in classroom activities, demonstrating how to use blogs, creating engaging learning environments, and participating in religious education activities at TPQ Al-Hidayah. The results of the program show that the use of diverse media can stimulate student interest and help improve their literacy and numeracy skills. However, consistent support and follow-up are still needed to ensure long-term impacts on student learning outcomes.]]>

<![CDATA[Observatorium Ilmu Falak Universitas Muhammadiyah Sumatera Utara (OIF UMSU) adalah fasilitas astronomi penting yang menunjang pengembangan ilmu astronomi dan kegiatan penelitian terkait fenomena langit. Salah satu komponen krusial dalam operasional observatorium adalah pengendalian lingkungan di dalam kubah observatorium, terutama suhu dan kelembaban. Kondisi lingkungan ini sangat berpengaruh terhadap kualitas pengamatan, kelangsungan instrumen, serta kenyamanan para peneliti dan pengamat. Oleh karena itu, diperlukan suatu sistem monitoring yang handal untuk menjaga kondisi lingkungan dalam rentang yang optimal. Tujuan dari penelitian ini adalah merancang dan mengimplementasikan sistem monitoring suhu dan kelembaban dengan mikrokontroler Arduino pada kubah OIF UMSU. Sistem ini diharapkan dapat memberikan informasi akurat mengenai kondisi lingkungan di dalam kubah secara real time. dan memudahkan tindakan preventif dan korektif terhadap kondisi yang tidak sesuai. Sistem yang dikembangkan menggunakan sensor DHT11 mampu mengukur suhu dan kelembaban dengan presisi tinggi; Sistem pemantauan suhu dan kelembaban kubah berbasis Arduino UNO mengukur suhu rata-rata 21 ° C dan kelembaban rata-rata 61%.]]>

<![CDATA[This study aims to enhance children's religious awareness through the teaching of fiqh (Islamic jurisprudence) on wudhu (ablution) and prayer in Desa Baru, Asahan Regency. The main issue addressed is the low level of understanding among children regarding the correct procedures of wudhu and prayer, which impacts the quality of their daily worship. This research employs a qualitative approach with a case study method. Data was collected through direct observation, in-depth interviews, and documentation during the educational program implemented within the KKN activities. The research findings indicate a significant improvement in children's understanding and practice of worship after participating in the fiqh wudhu and prayer learning program. Children who previously had limited knowledge of essential aspects of wudhu and prayer became more disciplined in performing their religious duties. Additionally, there was an increase in their motivation to learn more about religion, and positive behavioral changes were observed, particularly in maintaining cleanliness before prayer and punctuality in performing prayers. In conclusion, this fiqh learning program had a positive impact on enhancing children's religious awareness in Desa Baru.]]>

<![CDATA[Light pollution is a worldwide problem that affects fewer stars that can be seen at night. This study aims to measure the brightness of the sky in the zenith direction to minimize the effect of light pollution in observing celestial bodies. The research used the observation method of sky brightness level with SQM. Measurement of sky brightness was carried out in two places, namely in Medan and Serdang Bedagai. The SQM is mounted in a zenith direction and set to retrieve data every two seconds. Observations were made on November 10-13, 2018, during the new moon phase. The average value of sky brightness obtained in Medan is 18.05 mpsas and the NELM value is 4.00. Based on the Bortle scale, Medan is included in the ninth class area, namely the inner-city sky. Meanwhile, the average value of sky brightness obtained in Serdang Bedagai is 19.69 mpsas and the NELM value is 5.26. Based on the Bortle scale, Serdang Bedagai belongs to the sixth class area, namely bright suburban sky.]]>
