<![CDATA[The purpose of this study was to determine the mathematical concepts through ethnomatematics activities of rice farmers in the community in Blang Jrun village, North Aceh. This research is a type of qualitative research with an ethnographic approach. The subjects of this study were 8 people who work as farmers in Blang Jruen Village, North Aceh Regency. Data collection methods used were interviews, documentation and observation. The results showed that community farmers in Blang Jruen Village indirectly used ethnomatematics activities in rice farming. Ethnomatematic activities used include counting, counting and measuring activities. The most common activity in rice farmers is counting activity. In counting activities many mathematical concepts emerge by the farmers. Like addition; reduction; multiplication; division; worth comparison; and the comparison turned value. Whereas the spelling activity only appears in the mention of the vast rice fields. Measuring activity arises when estimating the distance between one crop and another and estimating the size of rice fields and yields. Conclusion, there are a lot of ethnomatematics activities in farming activities carried out by the Blang Jruen Village community in North Aceh Regency. Ethnomatematics activities include counting, counting and measuring activities. These concepts can be used as inspiration and contextual learning reference material. Keywords: Ethnomatematics Activities, Mathematical Concepts, Rice Farmers]]>

<![CDATA[The purpose of this study was to determine the role of tesselation in translational and reflection material in developing students' mathematical communication based on a scientific approach. The research method uses design research type validation study involving 30 students of class VII SMP 9 Palembang. The research process produces learning trajectory which contains a series of learning processes in two activities, namely scientific on translational material and scientific on reflection material. Every scientific activity consists of observing, asking, reasoning, trying, and forming networks. The results of the study showed that by providing learning material through a scientific approach, the role of tesselations could help students to carry out mathematical communication so that they could identify translational and reflection material. Therefore, students can understand the concepts of translation and reflection and solve problems related to the material. In conclusion, learning using tessellation with a scientific approach effectively helps students understand the concepts of translation and reflection. Through activities such as observing, asking, reasoning, trying, and forming networks Keywords: Mathematical Communication, Scientific Approach, Tessellation]]>
