PEMODELAN MATEMATIKA ALIRAN UDARA PADA BRONKUS AKIBAT PENYAKIT ASMA BRONKIAL
Get PDFBronchial asthma is a disease of the narrowing of the airways located in the human bronchi. One of the factors causing this narrowing is Particulate Matter 2.5. Particulate Matter 2.5 is a kind of particle with dust that can cause narrowing of the airways. These particles are very small, ie less than 2.5 micrometer and can enter the lungs. Mathematical modeling is a way of solving problems that describe a mathematical solution in the real world. Mathematical modeling can form a mathematical model that describes the flow of air on the bronchi due to bronchial asthma according to actual conditions and important influences in them. In this study formed a mathematical model of bronchial air flow due to bronchial asthma. Mathematical models are obtained from the momentum and mass equations which are solved using the finite volume method.

ANALISIS BERPIKIR LITERASI MATEMATIKA SISWA DALAM MENYELESAIKAN SOAL MATEMATIKA PADA POKOK BAHASAN POLA BILANGAN BERDASARKAN KECERDASAN MAJEMUK
Get PDFAbstract 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.

KEKONGRUENAN DAN KESEBANGUNAN PADA PERANGKAT UPACARA ADAT KEBO-KEBOAN ALASMALANG
Get PDFAbstract. Ethnomatematics is a habit and customs in a community group and there is a mathematical concept without being realized by the community. This research was conducted in Alasmalang village, especially Krajan Singojuruh Banyuwangi hamlet. The purpose of this study is to describe the ethnomatematics of Alasmalang kebo-keboan traditional ceremony which will then be developed into a worksheet for students. This student worksheet is equipped with a collection of questions that enhance creativity and teamwork called Escape Sheet. This research includes the type of qualitative research with an ethnographic approach. This research takes the object in the form of traditional ceremonies for kebo-keboan and its speakers, namely the Chair of Customary Institutions and Buldrah. Data collection is done with 3 methods, namely observation, documentation and interviews. The results of data collection were analyzed and presented descriptively. The results of the research that have been presented show the existence of mathematical concepts such as 2d figure,, similarity and congruence. In addition, the results also show the possibility of ethnomatematics that has been found to be developed into a collection of questions in the form of Escape Sheet.

ANALISIS PROSES BERPIKIR KOMBINATORIK SISWA DALAM MENYELESAIKAN PERMASALAHAN SPLTV DITINJAU DARI GAYA BELAJAR AUDITORIAL
Get PDFThis study aims to determine the student combinatorial thinking process in solving SPLTV problems. The research subjects were 5 auditory students in class X BIC 1 MAN 1 Jember. Data collection methods used are tests and interviews. Based on data analysis, the results of the study indicate that auditory students are able to use the concept and competence to provide combinatorial reasoning. At the stage of investigation the case students able to explain information, at the stage of calculating all cases, being able to write information using symbols but not being able to write down what was asked about the problem using symbols. At the systematic stage of generating a case, being able to make a plan so as to find a solution. At the stage of changing the problem into other combinatorial, able to find solutions more than one method or more than one method but there are students who have not been able to find solutions more than one method or more than one method, able to describe the reason or cause of the solution obtained.

ANALISIS KEMAMPUAN BERPIKIR TINGKAT TINGGI SISWA SEKOLAH MENENGAH PERTAMA DI JEMBER DALAM MENYELESAIKAN SOAL PELUANG PADA PEMBELAJARAN BERBASIS LESSON STUDY LEARNING COMMUNITY BERDASARKAN KECERDASAN EMOSIONAL
Get PDFHigh order thinking skill is the ability to complete the tasks where there is no algorithm that have been taught, that need justification or explanation and probably have more than one solution probability. High thinking skill ability is the ability that consists of analysis, evaluation and creation. Emotional intelligence is the individual intelligence in recognizing self-emotion, motivate yourself, control others emotion and foster relationships with others. Lesson study learning community is the collaborative learning from Japan. The aim of this research is to describe the process of student’s high order thinking skill in solving probability problem on LSLC based learning on emotional intelligence. The subject of this research started from giving emotional intelligence questionnaire, next the learning activity based on LSLC where the students work collaboratively on high order thinking questions on the students’ worksheet that consists of 3 questions covering question number 1 is question of analyzing, question number 2 is question of evaluating and question number 3 is question of creating, it was obtained the subject of 1 student with low emotional intelligence, 1 student with moderate emotional intelligence and 1 student with high emotional intelligence. From those three subjects, it was obtained 1 student with high emotional intelligence that has high order thinking skill, while 1 student with moderate emotional intelligence and 1 student with low emotional intellegence that did not have high order thinking skill.
