This research focuses on the effort to describe the difficulties experienced by students in the learning process on the subject of building a flat side room in mathematics learning. This research was conducted in connection with the difficulty of students in learning mathematics on the matter of building a flat side room. Therefore, it takes an effort to to find out the causes of difficulties experienced by students in the process of learning mathematics. One way that can be done is to identify the causes of student learning difficulties experienced by mathematics students during the process of learning mathematics took place in the classroom. This research will be conducted on the students of class VIII SMP Negeri 12 Bandung

In general, mathematics learning is monotonous, as a result the teaching process is teacher-centered, so students are less active in learning mathematics. So, a mathematical approach is needed, namely the Open-Ended approach. This research is a descriptive research with a qualitative approach. The subjects of this study were 30 students of grade VIII – A MTs Darul Irsyadiyah. Through the results of the Open-ended question test, the SPLDV material given to students of grade VIII-A MTs Darul Irsyadiyah amounted to 30 students obtained by students with critical thinking level group 4 (TBK 4) with a percentage of 10%, students of critical thinking level 3 (TBK 3) percentage of 13%, students of critical thinking level group 1 (TBK 1) with a percentage of 14%. Based on the results of interviews with open-ended syntax conducted on each group of TBK, it was concluded that students of grade VIII-A MTs Darul Irsyadiyah were only able to think critically on two or three indicators, this showed that students were not fully developed to develop critical thinking skills in solving open-ended problems of the Two Variable Linear Equation System (SPLDV) material.

This study investigates the three-dimensional geometric concepts and the underlying philosophical meanings embodied in the architecture of the Great Mosque of Al-Abror, Padangsidimpuan, employing a qualitative approach with ethnographic methods. The research is motivated by a notable gap in ethnomathematics scholarship, which has predominantly focused on identifying geometric forms without thoroughly integrating the associated philosophical and Islamic cultural values. Data were collected through direct observation, interviews with mosque administrators, and visual documentation, complemented by an extensive literature review. Data analysis was conducted using Miles and Huberman’s interactive model, encompassing data reduction, data display, and reflective conclusion drawing. The findings reveal that the mosque’s architecture incorporates a variety of three-dimensional geometric forms, including cubes, rectangular prisms, pyramids, cylinders, and spheres, which serve not only structural functions but also convey rich symbolic meanings, such as unity, steadfast faith, balance, and order in alignment with Islamic teachings. This integration of geometric analysis and philosophical interpretation offers a more contextualized understanding of mathematics and simultaneously fosters the internalization of cultural and religious values among learners. The novelty of this research lies in its comprehensive integration of geometric exploration with philosophical interpretation in the study of mosque architecture. Future research is encouraged to broaden the scope to other historical structures, develop technology-enhanced learning media, and evaluate their effectiveness in improving students’ academic performance and cultural appreciation.

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberdayakan warga Desa Silau Dunia melalui penanaman apotek hidup sebagai upaya peningkatan kesehatan, pemanfaatan lahan pekarangan, serta penguatan kemandirian herbal masyarakat. Program dilaksanakan melalui tiga tahapan, yaitu survei, sosialisasi, dan demonstrasi penanaman tanaman obat. Pada tahap sosialisasi, masyarakat diberikan pemahaman mengenai manfaat, jenis, dan teknik budidaya tanaman herbal, sedangkan tahap demonstrasi dilakukan melalui praktik langsung penanaman bibit jahe, kunyit, kencur, lidah buaya, sereh, dan temulawak. Hasil kegiatan menunjukkan tingginya antusiasme masyarakat, khususnya ibu-ibu PKK, dalam mengikuti seluruh rangkaian program. Program ini berhasil meningkatkan literasi masyarakat mengenai tanaman obat, memberikan keterampilan budidaya herbal, serta mendorong pemanfaatan pekarangan rumah sebagai ruang hijau produktif. Secara keseluruhan, kegiatan ini memberikan dampak positif terhadap kesehatan, lingkungan, dan potensi ekonomi rumah tangga di Desa Silau Dunia.
