NILAI KETAKTERATURAN TOTAL SISI DARI GRAF TANGGA PERMATA
Get PDFAbstract. Let graph G = (V,E) has V vertices and E edges. For every two different edges of graph G has total irregularity strength labelling ofG ifωt(e) ≠ωt(f) where graph G = (V,E) has V vertices and E edges. The weight edge ofxy of a graph G is ðœ”(xy) =ðœ†x) +ðœ†xy) + ðœ†y) where ðœ†x) is the label vertex x and ðœ†y) is the label vertex y and ðœ†xy) is the label edge of the xy. The minimum value on the biggest labels make a graph G, has irregular labeling which is defined as total edge irregularity strength and denoted by tes(G). In this article, The total edge irregularity strength of diamond ladder graph and
the union of diamond ladder graphs (isomorphic) are determined. The diamond ladder graph, denoted by Dln, is a graph consisting ofn diamond (n ≥2) .
Key Words : Total edge irregularity strength, Diamond Ladder Graph (Dln

PENERAPAN PEMBELAJARAN KOOPERATIF TIPE STUDENT TEAMS ACHIEVEMENT DIVISION (STAD) DENGAN AUTHENTIC ASSESSMENT UNTUK MENINGKATKAN AKTIVITAS DAN HASIL BELAJAR PADA MATERI LUAS PERMUKAAN DAN VOLUME LIMAS SISWA KELAS VIIID MTsN ARJASA JEMBER
Get PDFAbstract. The Using of unsuitable learning model will result unoptimal learning. To avoid this, the teacher should be careful enough in selecting and using learning models, especially involve students actively. The result of information obtained from interviews with mathematic teacher, the assessment carried out based on one test only. This research was conducted to improve the grade VIII D student’s learning achievement and their active participation through the implication of Student Team Achievement Division (STAD) method of cooperative learning type with authentic assessment on the surface area and volume of the pyramid at MTsN 1 Arjasa in the 2012/2013 academic year. The research design was Classroom Action Research (CAR), and the data collecting methods were observation, test, interview, and documentation. From the actions implemented in each cycle, it was proved that the students’ score improved from 66,65 in Cycle 1, to 78,94 in Cycle II. Thus, the average percentage of the second cycle was 83,33% and it fulfilled the research criteria, it showed that the implication of STAD can improve the students’ learning achievment and their active participation.

ANALISIS ALIRAN UDARA PADA JEMBATAN SURAMADU DENGAN MENGGUNAKAN METODE VOLUME HINGGA
Get PDFAbstract.This study was aimed to determine the air flow on the Suramadu bridge during extreme conditions. Computational Fluid Dynamics (CFD) is the science study of the flow fluida where air flow is one of them. The wind velocity data that will be examined in this study derived from the previous research. The other data, namely density, viscosity, gravity and pressure obtained from Wikipedia etc. The results of this study in the form of the mathematical model for air flow in the Suramadu bridge obtained using the vinite volume methods. The model was discretized by using upwind Quadratic Interpolation Convective Kinematics (QUICK) to obtain a matrix of size n x n that will be solved by using iterative cojugate gradient methods using MATLAB and Fluent programs. The resulth show that air velocity of Suramadu bridge is extreamly high. It dengerous for any vehicles through the bridge.

Get PDFAbstract.Strategy of Inquiry learning are series of learning activity that emphasize on critical and analitycal thinking process to look for and find its own answer from the problems asked. This strategy can improve the students mind in learning and students achievement in the classroom. Steps of inquiryare orientation, formulating problem, formulating hypothesis, collecting data, testing hypothesis, and formulating conclusion. The result showed that teacher and students gave good responses toward teaching learning activity by using inquiry. Those good responses were proved by the improvement of studends learning activities. Students competence in material Circumference and Area of circle reached 74,42%. Beside that, there is good effect of the students though after teaching and learning process. All of them showed that inquirycan help students to look for and find the answer of problems are studied.
