Abstract

This research aims to develop a mathematics learning medium in the form of an Indonesian culture-based e-comic integrated with the educational values ​​of Imam Syafi'i on the topic of Two-Variable Linear Equation Systems (SPLDV) to improve the mathematical problem-solving skills of students at SMP IT Al Maidani. The urgency of this research is based on the low mathematical problem-solving abilities of junior high school students, as well as the lack of contextual, engaging, and Islamic character-infused learning media. The development model used was the 4D model (Define, Design, Develop, Disseminate). The research subjects consisted of 30 students in the first trial and 32 students in the second trial. Validation was conducted by media experts, material experts, religious experts, and cultural experts. The validation results indicated that the developed learning medium was valid with an average score of 4.3 (media experts), 4.2 (material experts), 4.4 (religious experts), and 4.5 (cultural experts). The first trial resulted in an increase in the average score from 76.9 (pretest) to 83.73 (posttest), with an N-Gain of 0.32 (moderate category). Based on the reflection results of the first trial, revisions were made, including improvements to the interface, the addition of sample verification questions, and additional contextual exercises. After revisions, the second trial showed a significant increase, with an average score from 77.4 to 94.25 and an N-Gain of 0.78 (high category). A total of 87.5% of students achieved classical learning completion. The results of the study demonstrate that the developed e-comic media is valid, practical, and effective in improving students' mathematical problem-solving skills and instilling Islamic character values ​​aligned with the educational values ​​of Imam Syafi'i.

Abstract

Students often have difficulty understanding the concept of transformation geometry because it is abstract and has little to do with the real context. One of the causes is less meaningful and non-contextual learning. Therefore, one of the efforts that can be made is based on local wisdom. On the other hand, e-learning as an educational innovation has been widely used, but its application has not been optimal, especially to explain visual and abstract concepts such as transformation geometry. Therefore, an e-learning approach is needed that integrates contextual problems based on local wisdom to improve student understanding. This study aims to discuss the effect of e-learning learning based on local wisdom problems on improving students' understanding of transformation geometry. The research was conducted at Al-Azhar High School Medan, the subject of class XII research was 146 students who were selected by random sampling to select samples. The type of research used was quasi-experimental with a pretest-postest control group design. Data collection used a transformation geometry understanding ability test, including indicators of translation, dilation, reflection and rotation. The significance value of the Independent Sample t Test 0.00 < 0.05 means that there is a significant difference in the increase (gain) of experimental students with the control class. Through these results, it can be concluded that e-learning based on local wisdom problems has an effect on improving students' understanding of transformation geometry. The results of the dilatation indicator gain were 0.51, translation 0.54, reflection 0.47, rotation 0.44 with each category moderate.

Abstract

This study aims to explore and describe the mathematical concepts embedded within the Gedogan Karo weaving loom at the Jamin Gintings National Hero Museum. The primary focus is to identify the application of ethnomathematics in the tool's structure and the process of weaving traditional Karo cloth (Uis Karo). The methodology employed in this research is qualitative with an ethnographic approach. Data were collected through direct observation of artifacts in the museum, technical documentation, and a literature study regarding the weaving techniques of the Karo people to dissect the underlying mathematical elements. The results and discussion indicate an integration of formal mathematical concepts across four main aspects: (1) Geometry, through the formation of parallel lines in the warp threads and perpendicular relationships in the weft threads; (2) Geometric Transformation, evident in the symmetry, reflection, and translation patterns of the Uis Karo motifs; (3) Binary Logic, in the thread-lifting technique that resembles computer algorithm systems; and (4) Trigonometry, in the thread tension mechanism which depends on the leaning angle of the weaver's body. The conclusion of this study is that the Gedogan Karo loom is a manifestation of local wisdom that intuitively applies complex mathematical principles. The author suggests that these ethnomathematical exploration results be integrated into the formal mathematics education curriculum as contextual learning material. This is crucial for increasing students' interest in mathematics while simultaneously strengthening efforts to preserve Karo cultural heritage in the modern era.
