Abstract

Coronary heart disease is a disease caused by accumulation of cholesterol that forms plaques on artery walls for a considerable period of time. Over time, this disease can cause the heart muscle to weaken, and cause complications such as heart failure. One of ways to treat coronary heart disease is the stent installation (rings) or commonly called angioplasty. Angioplasty aims to make the blood vessels narrow to open so that blood flow flows better. The emergence of mathematical modeling as a new science is one alternative to solve these problems. With mathematical modeling, practitioners can make a form of a formula that describes the state of blood flow in the coronary arteries according to actual conditions without ignoring important factors in the system. In this study a mathematical model was built based on the above problems to determine the effectiveness of stent installation or angioplasty in the process that occurs in coronary arteries. Keywords: Coronary heart disease, Mathematical modeling, Stent

Abstract

Abstract This reseach was conducted to describe students mathematical literacy in solving mathematical questions on the subject of number patterns based on multiple intelligences. The instruments used were questionnaires, math tests, and interviews. The research subjects were six students consisting of two students with verbal linguistic intelligence, two students with mathematical logical intelligence and two students with naturalist intelligence. The results of this study are that students with verbal linguistic intelligence fulfill all indicators on the components of the literacy thinking process and can write answers in easily understood languages. Students with mathematical logical intelligence fulfill all indicators on the components of the literacy thinking process but there are stepping steps in writing answers. Whereas students with naturalist intelligence do not fulfill one of the indicators on the components of the first literacy process, namely students do not write mathematical situations using symbols. Students with verbal linguistic intelligence, students with mathematical logical intelligence and students with naturalist intelligence have different strategies in solving problems. Students with verbal linguistic intelligence tend to use detailed translation, students with mathematical logical intelligence are able to use mathematical operations well and students with naturalist intelligence tend to use images to solve problems. Keywords: Thinking in mathematical literacy, multiple intelligence, questionnaire
