<p><em>The purpose of this research is to analyze the ability of interpret symbols in numerical methods. The extent of the interpretation at the level of procedure and calculation only, or its already at the level of understanding of the concepts represented by symbols with good and right way. This type of research is qualitative research. The data that obtained are analyzed in descriptive.</em> <em>The election of the subject based on purposive sampling technique, i.e. taking the subject with considerations/criteria 6 semester students who was taking the course numerical methods, critical and active in discussions. The subject is only drawn by 1 student, subsequently coded MN1.The material is focused in determining the approximate root of equation with the method of false position.</em> <em>The methods used to collect data in this research is the observation, tests and interviews. So, that the triangular used in this research is the triangular techniques. Conclusion based on the results of the research showed the new symbols to interpret NM1 limited calculation procedure only. NM1 considers, with the same symbol but different forms of counting operation, was a mistake.</em> <em>NM1 gives the wrong result of conclusion renders the procedure is only seen from the similarity to the symbol, not the views of the concept behind the use of the symbol.</em></p>Fauzi MulyatnaWahyu Kusumaningtyas

<p><em>Based on interviews with researchers sources said that the beginning of the intestine embroidery is an art of genuine crafts. Called the intestine embroidery because this technique is a technique of combining a strand of cloth resembling the intestine formed according to the pattern by means of embroidered using a thread. Intestinal embroidery techniques were originally used to create a cover of the women's customary wardrobe of Lampung or often referred to as bebe. But not many people in Lampung, especially people who live in Lampung are still many who do not know and recognize the intestine embroidery because most only know tapis only characteristic of Lampung, besides that there are other cultural results that is embroidered intestine. There are still many who do not know that the intestine motif there is a knowledge of mathematics. The researcher's problem formulation is whether there are mathematical elements contained in the intestine embroidery motif based on the concept of geometry. The purpose of this study is to determine whether there are elements of mathematics contained in the intestine motif based on the concept of geometry. Subjects in this study consisted of 4 people obtained by purposive sampling technique. From the results of data analysis conducted by using descriptive analysis and discussion as follows: (1) Intestinal embroidery motif contains the meaning of mathematics and culture or often called Etnomatematika. On the meaning of culture there is a link between the embroidery intestine with a culture that has been there before as the existence of cultural linkage between Hindu belief Buddhism and there are similarities of motifs and decorative patterns contained in the motif embroidery intestine with ornamental variety in Indonesia. (2) The relationship between the intestine with mathematical motifs there are elements of mathematics such as geometry elements in the form of geometry of dimension one and dimension two, and the geometry of transformation. The concept of one dimensional geometry is a line, while the two dimensions are elliptical and rhombic. The concept of transformation geometry includes reflection or reflection, in which case this reflection is most prevalent in a motif contained in the intestinal embroidery motif, dilation or diminution and enlargement, rotation or rotation and transcation is a shift.</em></p>Leni Zuni IsnawatiFredi Ganda Putra
