Abstract

The bronchial airways are an important part of the respiratory system, it is not uncommon for the bronchi to experience disturbances, one of the disorders due to coronavirus diseases (Covid-19). Coronavirus diseases (Covid-19) are what cause narrowing of the bronchial tubes so that they will interfere with the speed of air flow. This airflow speed will be modeled with mathematical language. The mathematical model of air flow velocity in this study is formed based on equations of momentum equations which are then solved by the finite element method. Speed ​​analysis Air flow was simulated using MATLAB and FLUENT software. The problems studied are the effect of the narrowing diameter, initial velocity, and viscosity on the air flow velocity. Based on the research results show that the smaller the narrowing diameter and the viscosity of the incoming air, the greater the airflow velocity, while for the greater the initial velocity, the greater the resulting airflow velocity. Keywords: Coronavirus Diseases 2019 (Covid-19), bronchial, lungs, airways, finite element method.

Abstract

The research is about classroom action research in class XI MIPA 2 SMA Negeri 3 Bondowoso in the 2019/2020 school year. Data collection methods in this research are observation, documentation, and tests. The data obtained are student interest in learning, teacher activities and student learning activities during the learning process and learning outcomes in cycle I and cycle II. Student learning activity data obtained from observations. Student learning activities were analyzed descriptively. While the completeness of students' mathematics learning outcomes was obtained from the postest results. Classical student learning activities have increased in each activity indicator observed from cycle I to cycle II. This can be seen from students who do activity indicators, the percentage increases from cycle I and cycle II, from 73% to 93%. The increase in completeness of student learning outcomes occurred in each cycle, namely 31.5% in cycle I to 89.6% in cycle II. Based on the results above, it shows that the Reciprocal Teaching Strategy with Audiovisual Media can be used as an alternative to learning that can make students more active and can understand mathematical concepts in order to improve learning activities and student learning outcomes.

Abstract

Single ventricle is a heart defect in which one of the ventricle does not developed and bother the blood flow. One of the solutions is fontan surgery. The result of Fontan surgery allows the blood flowing in veins that initially lead to the heart change into the arteries. Because of these changes, there are possibility of swelling and velocity change of blood flowing. This research constructed a mathematical model of blood flowing velocity in arteries and veins due to a single ventricle heart defect that was formed from the momentum and mass equation, which was influenced by the diameter of venous vessel and blood viscosity. The analysis of the blood flow velocity in arteries and veins due to single ventricle heart defect was simulated by MATLAB and FLUENT software. The factors observed were the effect of venous diameter and blood viscosity on the velocity of blood flow in the veins. The result indicated that the greater diameter of the vein, the smaller the flow velocity in the vein. The greater blood viscosity resulted the smaller flow velocity in arteries and veins.

Abstract

One of the goals of learning mathematics is learning to communicate (mathematical communication). Mathematical communication skills are useful in gaining a better understanding of mathematics and a longer memory of learning mathematics. There are differences in communicating ideas, one of which is caused by differences in personality types. The personality types referred to in this study are extrovert and introvert personality types. This type of research is a qualitative descriptive study which aims to describe the profile of the extrovert and introvert students’ mathematical communication skills in solving the Three-Variable Linear Equation System question. This research was conducted in MAN 2 Jember and the research subject were all students of class X IPA 1. The data collection method used questionnaires and tests. The instruments used were personality type questionnaires, written test question, oral test question, and assessment rubrics. Based on the result of the analysis and discussion, it can be concluded that in general extrovert students and introvert students have similiarities and differences in written mathematical communication skills, namely extrovert students and introvert students alike can write down the information known from the questions, the type of methods to be used to solve the question, and use mathematical symbols. The differences is that introvert students can written down the steps for completion and conclusions, but not for extrovert students, this is because extrovert students end a job even though they have not found a solution. In analyzing a job, introvert students tend to take a long time, are more thorough, rushed, and give up easily in completing work. In general, it can be concluded that extrovert and introvert students can explain mathematical models from known information, state the type of methods to be used to solve problems, and used mathematical symbols. The difference is that extrovert students can explain the completion steps but not introvert students, this is because introvert students are hesitant and pessimistic, so they say cannot explain the completion steps even they not tried it.
