Abstract

Triangle and rectangle are material taught at the junior high school level. However, there are still many students who make mistakes in solving geometry problems. This can be a reference to find out what are difficulties experienced by students. The purpose of this study is to find out the types and causes of student errors in solving geometry problems. This research uses a qualitative approach. The subjects in this study were 3 students of class VII A MTs Surya Buana Malang. The results showed that the types of errors made by students were concept errors, procedural errors, and errors in understanding the questions. Concept errors made by students were errors in the types of triangle, properties of quadrilateral shapes, definitions of quadrilateral, concepts of operations on number, concepts of circumference, area of triangle and area of rectangle. Procedural errors made by students were mistakes in giving unit of perimeter or area, calculation, and understanding the problem. The causes of the error were students not being able to distinguish between angle and line segment, not being able to distinguish types of triangle based on angle and side, not being able to understand the concept of number operations, lacking accuracy, not understanding the difference in area and number of angle in triangle, lack of variation in questions given by the teacher, and lack of understanding about perimeter and area of the quadrilateral. AbstrakSegitiga dan segiempat merupakan materi yang diajarkan pada tingkat SMP.

Abstract

Graph labeling is one of the topics in graph theory which helps a lot in solved everyday problems. Study on labeling on graphs, especially the Super Edge-Magic Total Labelling is still ongoing, although for some classes of graph have been known to have Super Edge-Magic Total Labelling, but many problems that have not been resolved, one of them is the conjecture stated in the paper Enomoto et al (1998: 108 ) that all tree graphs have (super) edge-magic total labeling. Motivated by this conjecture, this study examined the total labeling of the super magical side of Graph T (2, n, n + 6) which is one of the tree graphs. The results of this study is show that Graph T (2, n, n + 6) is a graph that can be labelled by the Super Edge-Magic Total Labeling (SEMT), with the magic value of graph T (2, n, n + 6) for n is even number is k = 5n +23, and for n is even number the magic value is k = 5n +24.
