ANALISIS KECEPATAN ALIRAN HIDROGEN PEROKSIDA (H2O2) PADA STERILISASI SALURAN AKAR GIGI MENGGUNAKAN METODE NUMERIK VOLUME HINGGA
Get PDFAbstract. 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.

NILAI KETAKTERATURAN TOTAL SISI DARI GRAF TUNAS KELAPA
Get PDFAbstract. A total edge irregular labeling on a graph G which has |E| edges and |V| vertices is an assignment of positive integer number as labels to both vertices and edges so that the weights calculated at every edges are distinct. The weight of an edge xy in G is defined as the sum of the label of xy and the labels of two vertices x and y, that is w(xy) = ï¬(x)+ ï¬(xy)+ ï¬(y). The total edge irregularity strength of G, denoted by tes(G), is the smallest positive integer k for which G has an edge-irregular total k-labelling. In this paper, we determine the exact value of the total edge (vertex) irregularity strength of Coconut Sprout Graph (CRn,m) and the union of isomorphic and non-isomorphic Coconut Sprout Graph.
Key Words : total edge irregular labeling, total edge irregularity strength, coconut sprout graph

ANALISIS NUMERIK PROFIL SEDIMENTASI PASIR PADA PERTEMUAN DUA SUNGAI BERBANTUAN SOFTWARE FLUENT
Get PDFAbstract.Sand is one material that is very useful for human life that is often used to build a house that will be used as a human habitation. But not all areas of the river containing sand stored below the surface of the water, it depends on various factors such as the speed of the river flow, pressure, and position of the area of the river (curves, straight or it could be a meeting between the two rivers). In this study constructed a model of the shape of sand sedimentation analysis of the problems and solve the problem by using the volume up (finite volume method). The model is constructed based on the pressure and flow rate of the river, which is expected to know about the profile picture of sand sedimentation on a wide range of pressure and flow velocity pattern of the river. Based on the results of the simulation it was concluded that if both channels of the river has a flow rate of pressure and speed the same then the area of sand sedimentation areas potentially occur before the second meeting of the river, whereas if it has a level of pressure and velocity will be different after the confluence area with ideal conditions ie pressure and velocity of the river branch is higher than the main river.
