Abstract

Abstract. The sterilization of tooth root canal is one of phases at treatment of endodontic or pulp treatment or commonly called tooth root canal treatment. This treatment is necessary because over the years many doctors assumed cavities tooth that cause pain and can not cure, should be pulled out. Endodontic treatment is the appropriate treatment for patient. Endodontic treatment is one of the measures to maintain the tooth in the mouth as long as possible when the pulp tissue has been infected. This research construct a model of tooth root canal and solve sterilization problem by using the finite volume method. Model of simulation process is solved using MATLAB and FLUENT software. The model which is constructed based on direction syringe spray and impeller pressure. Based on the result of the research, if angle of syringe spray is getting greater then the velocity is getting lower, if the angle of syringe spray is getting smaller then the velocity is getting higher. If the value of impeller pressure is more than 6 Pa then velocity is higher, if the value of impeller pressure is less than 6 Pa then velocity is negative value, whereas if the value of impeller pressure is 6 Pa then velocity is moderate value and the change of domain length of tooth root canal is not to great, so the spreading of velocity is evenly. Key Words : Treatment of endodontically, Sterilization of Root Canals, Angle of Syringe Spray, Impeller Pressure, Finite Volume Method.

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. A Wind turbine is a wind energy converters tool into electrical energy. To optimize the electrical energy converted, it needs for further research on wind turbine process. In this research, the analysis part of wind turbine is rotor, which is the contacted part to the wind. Type of wind turbine that will be analyzed in this study is HAWT (Horizontal Axis Wind Turbine) type because this model is the most often used type and can produce great electrical energy. This research construct a model of the air flow field form of wind turbine rotor and solve these problems by using the finite volume method. Model simulation process will be done by using MATLAB and FLUENT software. The analysis was performed with the variation initial velocity level of wind. It is 3 m/s, 5 m/s, and 7 m/s. The simulation results showed that the velocity of rotation wind turbine rotor blade higher when the initial wind velocity increases. Beside that, the result is when the initial wind velocity of 7 m/s and 5 m/s, the velocity of rotation wind turbine rotor blade tend to be more stable. With 5 m/s of wind velocity to wind turbine rotor, The difference between an average direct calculation and a SOR iterative calculation is obtained the value of relative error less than 0.1%. it is 0.079%. So the finite volume method of numerical methods is effective to solve this problem. Key Words : Electrical Energy, Finite Volume Method, Velocity, Wind Turbine,.

Abstract

Abstract. Coffee bean is one of the superior agricultural products in Indonesia. One of the factors that affect the productivity is the cropping pattern of coffee plants. A well organized cropping pattern will make a well organized air circulation which affects the productivity of coffee beans. In this research, a model of air circulation is built based on prism graph for the cropping pattern and solved by using Finite Volume Method (FVM). The model simulation process is done by using MATLAB and FLUENT software. The model is built according to the slope of stem and the temperature of coffee plantation. The temporary result of the research shows that prism graph cropping pattern results good air circulation and also gives good effect to the air circulation around the coffee plantation. The same thing happens to the effect of the slope of stem, the more upright the coffee plant is, the better air circulation and vice versa. Key Words : Coffee plants, air circulation, prism graph, Finite Volume Method (FVM)

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
