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

Abstract. The problem based learning model or known as Problem Based Instruction (PBI) always presents problems in real life context. This learning model has brought the students to get involved in the process of finding and investigating. The steps in this learning model were directing the students to the problems, organizing the students to learn, helping independent and group investigation, developing and presenting artifact and exhibits, and also analyzing and evaluating of problem solving. This research applied two cycles covering planning, action, observing, and reflection. The Approach used in this research was qualitative approach. This research was a Class room Action Research Design (CAR). This research design was adopted from Hopkin’s, which each cycle has four phases or steps, those are planning, action, observing, and reflection, and then continued to the following cycle. Data collection method used in this research was test, observation, documentation, and interview. Acording to the observation, the students individual activity from the first up to the fourth meeting is 69,87%, 72,22%, 74,3% and 79,72%, and the students group activity from the first up to the fourth meeting is 75,27%, 76,13%, 80,83% and 91,1%. The percentage of the students who achieved the target was 82.5%, with 7 students were failed in the first cycle. In the second cycle, the percentage of the students who achieved the target was 95% with 2 students were failed. Key Words : Problem Based Instruction, Achievements

Abstract: In 2013, there were changes of curriculum in Indonesia. The name of new curriculum is 2013 curriculum. The difference of 2013 curriculum is the student book has been provided by The Goverment. Analysis on student book is needed for reviewing the suitability of student book by 2013 curriculum formulation. Analysis was done based on four criteria, that are competence, material, scientific approach and authentic assessment. Research instrument was form of questions that consist of : 11 competence questions, 11 material questions, 10 scientific approach questions, and 8 authentic assessment questions. Analysis result showed the persentage of competence suitability is 80,49% (good categories), for the persentage of material suitability is 81,06% (good categories), for the persentage of scientific approach suitability is 95,83% (very well categories), and the persentage of authentic assessment suitability is 88,80% (very well categories). Keywords: analysis, 2013 curriculum, student book.

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. Era industrialisasi yang berkembang sangat cepat membutuhkan sumber daya energi yang cukup besar, dimana sebagian besar sumber daya energi tersebut semakin berkurang dari waktu ke waktu. Untuk itu dibutuhkan suatu sumber daya energi alternatif yang diharapkan bisa menggantikan sumber daya utama yang semakin berkurang tersebut. Salah satu energi alternatif untuk pemanasan ataupun pembakaran adalah menggunakan oven berbantuan surya yang berguna tetapi memiilki dampak yang ramah terhadap lingkungan. Dari penelitian yang sudah dilakukan dengan menggunakan metode volume hingga dan diselesaikan dengan teknik diskritisasi QUICK maka didapatkan bahwa energi surya dapat dimanfaatkan dengan maksimal jika oven berbentuk kubus dan diberi sekat-sekat, hal ini juga berpengaruh terhadap temperatur awal yang masuk, semakin besar energi surya yang terserap maka proses pemanasan akan berlangsung dengan baik. Sedangkan penyebaran temperatur cukup merata dengan temperatur tertinggi pada oven surya berbentuk kubus adalah terletak pada tengah kubus. Key Words :Modelling, Oven Surya, Finite Volume Method

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. In this research will also related with high order thinking skills with six aspects as indicators. Those aspects are Remembering, Understanding, Applying, Analysing, Evaluating, and Creating. The results of this research are four theorems about super ℋ-decomposition antimagic total coloring on Prism Graph and subdivision of Prism graph and related with high order thinking skills. Keywords: Super -Decomposition Antimagic Total Coloring, Prism Graph and Subdivision of Prism Graph, High Order Thinking Skills
