Abstract

Abstract. The purpose of this research is to increase students’ activities and learning achievement score. This research implemented Student Teams Achievement Division methods by using Mind Mapping. This research type is a Classroom Actions Research (CAR) of two cycles, there are two classes in each cycles. In the first cycle the research taught rectangular topic, whereas in the second cycle is a square topic. The research methods are documentation, observation, test and interview. The data analysed in this research are students’ activities and students’ achievement score, teacher’s activities. The research show that the student activities attaine 60,38% in the first cycles and 76,95% in second cycles. The teacher activities attaine 75% in the first cycles and 91,66% in second cycles, and  the achievement score attaine 76,40% in the first cycles and 85,22% in second cycles. It can be concluded that the implementation of Student Teams Achievement Division learning model is able to improve student learning outcome.   Key Words: Student Teams Achievement Division, mind mapping, students’ test result, students’ activities.

Abstract

Abstract. Let G=(V,E) be a simple graph, a labeling is called an edge irregular total k-labelling of G if for any two different edges e and f of G there is, . The total edge irregularity strength denoted by tes G is the smallest positive integer k for which G has an edge irregular total k-labelling. In this paper, we will determine the total edge irregularity strengths of a Snail graph, the union isomorphic and non-isomorphic union of Snail graph, and shackle graph of Snail graph. We show that , for , , for and , , for where natural numbers, and , for and Key Words: Total edge irregular labeling, Total edge irregularity strength, Snail graph.

Abstract

Abstract. A G graph of order p and size q is called an (a,d)-edge antimagic total if there exist a bijection f:V(G)∪E(G)⟶{1,2,…,p+q} such that the edge-weights, w(uv)=f(u)+f(v)+f(uv), uv∈E(G), form an arithmetic sequence with first term a and common difference d. Such a graph G is called super if the smallest possible labels appear on the vertices. In this paper we study super (a, d)-edge-antimagic total properties of connected Tribun graph. The result shows that a connected Tribun graph admit a super(a,d)-edge antimagic total labeling ford=0,1,2 for n≥1. It can be concluded that the result of this research has covered all the feasible n,d. Key Words: (a,d)-edge antimagic vertex labeling, super(a,d)-edge antimagic total labeling, Tribun Graph.

Abstract

Abstract. Coffee beans are one of Indonesian main export commodities. It can be seen from the amount of coffee exported to other countries, especially Europe. However, the vast area of coffee plantation does not make the productivity of the coffee beans become maximum. There are several factors which influence this condition. One of them is the cropping pattern of coffee plant and the air circulation that affect the pollination process of coffee flower. In this research, an air condition models was designed to solve the problem by employing Volume Hingga method. The models were designed based on the level of plant roughness, distance between coffee plants, and the cropping pattern of coffee (Diamond Ladder Graph). The results of the research is the mathematical models that influenced the level of plant roughness and the cropping pattern of coffee with angle. The symbol of plant roughness in this model is . Coefficient is limited at 0 until 1 (0< <1). The high value of plant roughness coefficient shows the high level of plant roughness. Key Words: coffee plant, air circulation, level of plant roughness, Volume Hingga Method, Diamond Ladder Graph.

Abstract

Abstract. This study aims to describe the process of thinking student of mathematics education with high spatial intellegent in solving geometry problems based steps Polya problem solving. This research is a qualitative descriptive study. The subject of this study is a second semester students of Mathematics Education IKIP PGRI MADIUN with a high degree of spatial intelligence. Data collection techniques were used that method of written test and interview-based tasks. Data analysis was conducted based on data written test and interview-based tasks. Furthermore, to obtain valid data triangulation method of writing data from and interviews. This research resulted in the description of the thought processes of students with a high level of spatial intelligence in solving geometry problems. In understanding the problem using the thought process of assimilation, in a problem-solving plan to use the thinking process is less than perfect assimilation and accommodation. In implementing the plan of solving students with high spatial intelligence using the thought process of assimilation. While in checking the breakdown of students with high spatial intelligence the process of assimilation and accommodation. Keywords: thought processes, spatial intelligence, geometry problem solving.
