Abstract

Geometry is one of the material in mathematics that is studied by students. In measuring students' geometry abilities, one of the efforts can use van Hiele's theory. This research is a descriptive study with the subject of the research is grade IX D students of SMP Negeri 2 Jember. The purpose of this study is to describe the characteristics ofthinking geometry students'at the level of visualization, analysis, and informal deduction. Research subjects were 5 students with 2 students at the visualization level, 2 students at the analysis level, and 1 student at the level informal deduction. The results of this study indicate that (1) Visualization subjects can identify, classify, compare and determine the types ofshapes quadrilateralbased on their visual appearance and can draw with labeling simple. (2) The subject of analysis can identify, analyze, classify, define and compare quadrilateral shapes according to the relationship between their properties. (3) The subject of informal deduction can define and compareshapes quadrilateralby looking at the relationship between quadrilateral shapes

Abstract

One of the main activities of block ice production is the process of freezing ice blocks in the brine tank. Brine Tank is a tank that functions to freeze ice blocks. Brine Tank contains salt water. Mathematical modeling is a formulation of mathematical models that describe how to get a solution to a mathematical problem in a natural event. Mathematical modeling can form mathematical models that describe the process of ice freezing in brine tanks in accordance with actual conditions without ignoring important factors in the system. The mathematical model in the process of ice freezing in the Brine Tank is obtained from the momentum equation and the energy equation which is solved using the finite volume method. In this study a mathematical model was built to determine the effectiveness of time in the ice freezing process in the brane tank.

Abstract

This study aims to determine the geometry skills of class X students in solving quadrilateral questions based on van Hiele's level. The research subjects were 6 students of grade X MIPA 4 in SMA Negeri 1 Jember. Students are given van Hiele level classification test questions, geometry skills test questions, and followed by interviews. This type of research is a qualitative descriptive study. The results obtained are students at the rigor level have visual skills, verbal skills, and logic skills. Students at the deduction level have visual and drawing skills. Students at the informal deduction level have visual skills, logic skills, and applied skills. Female students who are at the analysis level have visual skills, verbal skills, logic skills, and applied skills. Male students at the analysis level have visual skills. Students at the visualization level have visual skills.

Abstract

Ethnomatematics is mathematics which found in the culture of the community where the community has unknowingly applied the concept of mathematics in the culture. The purpose of this research was to describe ethnomatematics in the petilasan prabu Tawang Alun building and produce student worksheets. This type of research is qualitative research with an ethnographic approach. There are four subjects of this research, namely one building administrator and three building carving experts. Data collection methods used are observation, interviews, documentation, and triangulation. This research focused on the stage, body, legs, stairs, and carvings on the petilasan prabu Tawang Alun building. The results of this study indicate the presence of ethnomatematics in the petilasan prabu Tawang Alun building. Geometry concepts or elements found include: flat shapes (triangles, squares, rectangles, circles, trapezoid), space structures (beams), congruent, and geometrical transformations (translation, reflection, and dilation. Ethnomatematics in this research will be made worksheets are intended for class IX in even semester with geometrical transformations material.

Abstract

This study aims to describe the mathematical literacy of field-dependent (FD) students and field-independent students (FI) in solving PISA questions on Change and Relationship content in terms of the achievement of mathematical literacy levels. The PISA issue of Change and Relationship content is related to curriculum material, namely functions and algebra. This research is a qualitative descriptive study. The subjects in this study were students of class X MIPA 6 of SMA Negeri 1 Jember with 29 students consisting of 6 field-dependent (FD) students and 23 field-independent (FI) students. The results showed that the level of mathematics dependent literacy of field-dependent students was at level 2 (66.67% or as many as 4 students) and level 5 (33.33% or as many as 2 students) and the level of mathematics literacy of independent field students was at level 2 (13 % or as many as 3 students), level 5 (69.56% or as many as 16 students) and level 6 (17.4% or as many as 4 students).
