The type of this research is qualitative with the ethnographic approach and two subject research. Calculating activity appears when determining the length and width of a body with a certain size, determining the height of the filter location, determining the size of the length for the base and lid, making the net cover, determining the volume of parts, determining wages, and making certain diameters. Measuring activity arises when measuring the location of the filter's height, measuring the length and width of the casing, measuring the length of the radius of the base and lid, and measuring the length of the wire. Designing activity arises when the craftsman makes a ruler, makes a filter hole, makes the nets close, and emerge mathematical concept about two-dimentional figure and three-dimentional figure. Making student teaching materials in the form of a package of test questions with the topic of ethnomatematics on craftsmen in the making of dandang with material to construct curved side spaces.

Get PDFAbstract. The purpose of this research is to analyze student’s errors based on Watson's criteria reviewed from gender. From the results, it can be known the types of student errors, the percentage, and the causes of student’s errors that occur. The research is descriptive qualitative. Data collection was done by test and interview. The test are given to the students to find out the types of errors that occur when they complete it. The interview with subjects is done to find out the reason why they did error in completing the test. Subject in this research are 10 students in class VIII C of Junior High School 8 Jember. Five male students and female students. Based on the result of this research, the male students are disposed to do an error omitted data with 13,33%, 13,33% response level conflict, and 16,67% above other. The female students are disposed to do an error omitted conclusion with 24,14%.

ETNOMATEMATIKA PEMBUATAN KERAJINAN TANGAN ANYAMAN BAMBU MASYARAKAT OSING DI DESA GINTANGAN BANYUWANGI SEBAGAI BAHAN AJAR GEOMETRI
Get PDFEthnomatematics is the application of mathematics in cultural life. The purpose of this study was to describe ethnomatematics of making woven bamboo handicrafts in the village of Gintangan Banyuwangi. The things obtained in this study were changed in the form of geometric teaching materials, namely the Test Problem Package with the topic of Ethnomatematics. This type of research is qualitative with an ethnographic approach. Data collection methods used are observation and interviews. The subjects of the study were 2 people, namely a foreman making woven bamboo crafts, kukusan, ereg, tenong, and nyiru and a maker of bamboo woven kukusan, ereg, tenong, and nyiru. Ethnomatematics emerged when the woven craftsmen carried out activities to measure, calculate and design. When the process of measuring the thickness of the bamboo sharpener comes the measurement concept using meters (m). During the process of calculating the drying time of bamboo and the amount of bamboo sharpener a comparative concept of value appears. During the design process, the concept of quadrilateral and number sequences emerged. The results of the study are geometry teaching materials in the form of a test test package. The question test package is intended for class VIII middle school students. This Question Test Package consists of 4 C5 and 1 C6 questions Keywords: Ethnomatematics, Bamboo Woven Crafts, Geometr
PEMODELAN MATEMATIKA PENYEBARAN POLUTAN UDARA DI KAWASAN PLTU MENGGUNAKAN METODE VOLUME HINGGA
Get PDFThe existence of a Steam Power Plant greatly helps human electricity needs.The other side, the existence of the power plant activity has a negative impact on the environment. The use of coal fuel produces an air pollutant. The spread of air pollutants is influenced by interrelated variables. The existence of mathematical modeling as an applied science helps represent a problem from real world situations into mathematical language to find solutions to these problems. Mathematical modeling helps build a mathematical formula that describes the spread of air pollutants with actual conditions without ignoring important factors in the system. The analytical exact solution to the problem of spreading air pollutants is very difficult. Therefore, a numerical method approach is used in the form of a volume up method. In this research a mathematical model was built on the distribution of air pollutants based on momentum and mass quantity equations.
