Abstract

This research analyzes a continually evolving culture deeply ingrained in every region of Indonesia. Jember Regency, located in East Java, boasts a rich tapestry of cultures encompassing customs, food, language, games, and more. This research uses qualitative. The research focused on batik, specifically analyzing the geometric transformations within Labako batik motifs. These transformations include translation, reflection, rotation, and dilation. A total of eight motifs were identified from four Labako batik cloths, featuring elements like water hyacinth plants, bamboo, tomato and tobacco leaves, winged beans, and coffee and cocoa fruits and leaves. This research seeks to identify geometric concepts within each motif for use as teaching materials, indirectly promoting batik preservation and supporting Labako batik craftsmen. It is also hoped that this research can be used as a reference for future studies.

Abstract

  This study aims to explain students' cognitive abilities or we know it as the word commognitive which is a thinking process that is communicated both verbally and in writing. In solving contextual-based mathematical problems related to the concept of integers, of course it will be easy to solve the problem. This study is qualitative description. This study uses pretest, posttest, and interviews. The results obtained are that high-ability students fulfill the four stages of problem solving with commognitive components. At the stage of understanding the problem with the commognitive word use component, the subject is able to write down all the information that is known and the subject can determine what is asked in the question correctly. At the stage of making a plan with the commognitive word use component, visual mediator, narrative, the subject is able to mention the appropriate formula, the subject uses visual media according to the structure being asked, and students can describe the formula and use of visual media used correctly. While low-ability subjects fulfill three of the four stages of problem solving with the commognitive component. At the stage of understanding the problem, the subject is unable to write down all the information that is known correctly, but the subject can determine what is asked in the question correctly. at the stage of making a plan with the commognitive word use component, visual mediator, narrative the subject was unable to mention the formula that corresponds to the question, the subject did not use visual media and the student was unable to describe the formula correctly. At the stage of implementing the plan with commognitive the subject was unable to solve the question correctly and at the last stage of looking back with the commognitive component the subject was unable to determine the results of the question and the student was unable to explain again how to work on the question.

Abstract

This study aims to develop learning media in the form of mathematical playing cards on the material of distance and volume units and to determine the level of feasibility and practicality of the developed media. This study uses the research-and-development (R&D) method with the ADDIE development model, which includes the stages of analysis, design, development, implementation, and evaluation. However, the scope of the study is limited to the formative evaluation stage, namely the results of expert validation and teacher responses, without continuing with experimental effectiveness testing. The research subjects included media experts, material experts, and eighth-grade mathematics teachers of SMP Negeri 3 Ambulu. Data collection techniques were carried out through observation, interviews, and validation questionnaires. The data obtained were analyzed descriptively and quantitatively using a feasibility percentage. The results showed that the mathematical playing card media obtained an average value of 88% from media expert validation with a very feasible category. Material expert validation showed an average value of 85% with a feasible to very feasible category, which indicates that the material and questions presented were in accordance with the basic competencies and learning objectives. In addition, teacher responses to the use of the media showed an average value of 90% with a very practical category. Based on these results, it can be concluded that the developed mathematical playing cards media meets the criteria of validity and practicality, so it is suitable for use as a learning medium for the material of distance and volume units for class VIII students of SMP Negeri 3 Ambulu. This media is expected to be an innovative alternative in mathematics learning and can be further developed through further research to test its effectiveness in improving student learning outcomes.
