Abstract

Abstract. The air flow velocity is one of many factor which should be considered in building a skyscraper. This is because the air flow velocity can affect the comfort of house room. The method which is used to solve the air flow analysis is a finite volume withusing Quadratic Upwind Interpolation Convective Kinematics (QUICK) discretization technique. Finite volume method is used to obtain a mathematical model of air flow velocity and QUICK is used to discretize it such that it will yield a linier equation system in a matrix of size (mn)×(mn). To simulate the air flow analysis is used Matlab and Fluent softwares. The result show that if the barrier is higher the air flow velocity will be decreased and if the distance of barrier is longerthe air flow velocity will be increased. It can be conclude that this analysis can be applied to have a comfort house room. Key Words : air flow velocity,mathematic model, finite volume method,QUICK

Abstract

Abstrak. Model sistem kekebalan tubuh terhadap infeksi Mycobacterium tuberculosis telah dikembangkan dan dikemas dalam bentuk sistem persamaan diferensial biasa non linier order satu. Model tersebut sangat komplek sehingga memerlukan metode numeric untuk menyelesaikannya. Salah satu metode numerik yang yang efektif adalah metode Runge-Kutta. Penelitian ini akan merumuskan formula metode Runge-Kutta order sembilan, dan menentukan sifat dari metode tersebut sebelum merumuskannya, serta menganalisis konvergensi dan efektivitas dari metode Runge-Kutta order sembilan bila dibandingkan dengan metode Adam Bashforth-Moulton order sembilan. Metode dikatakan efektif dan efisien bila error yang terjadi pada metode dalam menyelesaikan model semakin kecil (menuju nol) dan waktu yang dibutuhkan metode untuk menyelesaikan model matematika semakin sedikit. Hasil penelitian menunjukkan bahwa metode Runge-Kutta order sembilan lebih efisien dan efektif dibandingkan metode Adam Bashforth-Moulton order sembilan dalam menyelesaikan model sistem kekebalan tubuh terhadap infeksi Mycobacterium tuberculosis. Kata kunci : Metode Runge-Kutta order sembilan, konvergensi, efektivitas, model sistem kekebalan tubuh terhadap infeksi Mycobacterium tuberculosis.

Abstract

All graphs in this paper are unorientated, simple, connected, and planar graphs. Super ℋ-decomposition antimagic total labeling on a graph is a bijective function that fulfills for every two neighboring isomorphic subgraphs (just share vertex elements and minimumly share one vertex) and , , where for each , , is a subgraph of graph that contains vertexs and edges , , , . Next, it is called coloring if many of different weights is at its minimum. In this paper, we will find the existence of chromatic numbers of super ℋ-decomposition antimagic total coloring on Prism Graph and subdivision graph of Prism graph.

Abstract. For a simple undirected connected graph G(V,E) with vertex set V and edge set E a labeling  : V  E → {1, 2, 3, ..., k} is called a total k-labeling. A total k-labeling is defined to be an edge irregular total k-labeling of the graph G if for every two different edges uv and xy of G there is t(uv) ≠ t(xy). The minimum k for which the graph G has an edge irregular total k-labeling is called the total edge irregularity strength of the graph G, denoted by tes(G). In this paper, we determine the total edge irregularity strength of volcano graph tes(Gbm,n) and the total edge irregularity strength of s copies volcano graph tes(sGbm,n). Key Words : edge irregular total labeling, total edge irregularity strength, volcano graph

Abstract

Abstract. Materials to produce fertilizer are NH3 Liquid and CO2 gas. Required CO2 gas should be free from condensation, so CO2 gas is refrigerated in intercooler. In this research, we analyse of mathematic model for heat transfer in fluid with finite volume method. We will review how the CO2 gas cooling process from mathematics model point of view. We will model the equations for CO2 gas cooling process which includes momentum dan energy. After that this model will be discretizatied. For numerical solution, we will use Matlab and Fluent to simulate CO2 gas cooling process. The simulation result using Matlab and Fluent forms will be presented descriptively in charts, tables, and images to show how the distribution process of heat transfer. The result show for error is 0,0087. In conclusion the model accurate for solving heat transfer process in CO2 gas. Key Words : Mathematics Models, Heat transfer, Finite Volume Methode,

Abstract. The rainbow connection of the graph of G = (V, E) if for each pair of points u and v in G there is a path with points u and v as the end points on each side obtaining different colors, the path is called the rainbow path. The rainbow-connected number graph G is the smallest positive integer such that G has a rainbow connection staining denoted rc(G). While the graph is said to be a rainbow 2-connected staining on G if for each pair of points u and v on the sides there are 2 different paths, with u and v being the end points of each side obtaining different colors and 2 passages can not intersect each other, denoted rc2 (G). Let G be the graph connected with so that , with d is degrees. Let G be a rainbow so that where κ is the number of paths of rainbow connecting every two distinct points in G. The results of this research are new theorem about the rainbow connection and 2-rainbow connected. Keywords : rainbow connection, 2-rainbow connected, rainbow path

Abstract

Abstract.The use of ICT in Indonesianeducation especially in the field of mathematics is less optimal. It would require the development of materials that use e-learning to facilitate students in learning. The device was developed by a model of learning missourimathematics project (MMP). The developments of material methods are using the method of Thiagarajan, Semmel and Semmel. Based on the results of the expert appraisal, validity coefficient of lesson plans,worksheets,student books, THB and e-learning in a row is 0.94; 0.96; 0.90; 0.93 and 0.92 which means the device is already valid. Observations of teachers in managing the learning ability, the percentage of student activity, student questionnaire responses, student self-assessment questionnaires and tests learning outcomes showed that the device is practical and effective. Key Words :Missouri Mathematics Project,Learning device, E-learning, Moodle.
