Abstract. An  (a, d)-edge-antimagic  total   labeling  of G  is a  one-to-one  mapping taking the vertices and edges onto {1, 2, 3, . . . , p + q} Such that the edge-weights w(uv)  = (u)+(v)+(uv), uv ∈ E(G)  form an arithmetic sequence {a, a+d, a+2d, . . . , a+ (q − 1)d}, where first term  a > 0 and  common  difference d ≥ 0.  Such a graph G is called super if the smallest possible labels appear on the vertices.  In this paper we will study a super edge-antimagic total labelings properties of connective Swn graph.   The result shows that a connected Silkworm graph admit a super (a, d)-edge antimagic total labeling for d = 0, 1, 2. It can be concluded that the result of this research has covered all the feasible n, d.   Key Words: (a, d)-edge-antimagic total labeling, super (a, d)-edge-antimagic total labeling, Silkworm graph.

Abstract

  Abstract. There are many students who have difficulty in solving math problems. The difficulties caused students mistake in solving problems. The of student’s mistakes consist of the use of computation errors, errors due to a lack of basic knowledge, reduction errors, and another errors. Therefore, the aplication of cooperative learning model with Mind Mapping technic is important to overcome the student’s mistakes in solving the Fraction problems at seven grade SMP Negeri 14 Jember odd semester academic year 2013/2014. This research type is a Classroom Action Research (CAR). The data analysed in this research are student’s activity, student’s mistakes, and effectiveness. The research show that student’s activity attain 66,48% in the first cycle and 71,62% in second cycle, student’s mistakes attain 50,72% in the first cycle and 34,28% in second cycle, and effectiveness attain 33,64% in the first and 60,67% in the second . It can be concluded that the application of cooperative learning model with Mind Mapping technic is effective to overcome student’s mistakes in solving Fraction. Key Words: Cooperative learning model with Mind Mapping technic, fraction, student’s activity, student’s mistakes, effectiveness

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. 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.
