PEMODELAN MATEMATIKA ALIRAN UDARA PADA BRONKUS AKIBAT PENYAKIT BRONKITIS KRONIS
Get PDFChronic bronchitis is a disease that attacks the respiratory tract and is one of the dangerous diseases that can cause death in the world. This study builds a mathematical model of airflow velocity in the bronchi due to chronic bronchitis which is influenced by mucus thickness and initial velocity. The type of research used is simulation research to find a picture of a simple system that will be manipulated or controlled to get an effect similar to the actual situation. The mathematical model is built on the reduction of the momentum equation and the mass continuity equation which is solved using the finite volume method and the QUICK discretization technique. The volume method is used because the fluid flow studied is O2 gas which is classified as unstructured. So by using the volume method, it will be easier to discretize to determine the values ​​that will be sought in the discretization process

Get PDFThis development research produces online interactive learning media using GeoGebra-assisted linear programming Easyclass. The purpose of this study is to describe the process and results of developing interactive online learning media using GeoGebra-assisted Easyclass linear program material. Research using the 4-D Thiagarajan model. The study was conducted at MAN 2 Jember, followed by 24 students of class XI IPA 4. The results showed a correlation value of 0.917 so that the media was declared valid with a very high category. Practicality was analyzed based on a student response questionnaire showing a percentage of 99% so that it was declared practical with excellent criteria. The effectiveness was analyzed based on the test scores of student learning outcomes after using instructional media obtained a percentage of 88% of the number of students who scored more than 75 which were categorized very well. Based on the results of data analysis, online interactive learning media using Easyclass-assisted GeoGebra linear program material meets the criteria of validity, practicality and effectiveness so that the media can be used in carrying out learning activities.

ETNOMATEMATIKA PADA AKTIVITAS PEMBUATAN BATIK MOTIF TEMBAKAU DI RUMAH PRODUKSI BATIK NHORA PENGESTU AMBULU SEBAGAI BAHAN PAKET SOAL TES
Get PDFEthnomatematics is the science of mathematics practiced by a cultural group where the society has unconsciously applied the concept of mathematics. The purpose of this study is to describe ethnomatemics in the activity of making tobacco motifs and to produce test packages. This type of research is a qualitative research with an ethnographic approach. There are three subjects in this study, S1 as the maker of patterns / designs, color locking, and "nglorod", S2 as a dyeing and coloring, and S3 as the maker of batik cap. Data collection methods used are observation, interviews, and documentation. This research is focused on the tobacco making batik activity. The results of this study indicate the existence of ethnomatematics which includes activities: counting, measuring, and designing. Ethnomatematics in this study was made as a test package in the form of descriptive questions for even ninth grade students

KEMAMPUAN VISUAL SPASIAL SISWA DALAM MENYELESAIKAN SOAL PISA KONTEN SHAPE AND SPACE BERDASARKAN GAYA BELAJAR
Get PDFThis study aims to describe students' spatial-visual ability in solving PISA questions in shape and space content based on visual, auditory, and kinesthetic learning styles. This type of research used in this research is descriptive qualitative research. Subjects in the study were six students from Class X MIPA 3 SMA Negeri 2 Tanggul consisting of two students from each of the visual, auditory and kinesthetic learning styles. The data collection methods used were questionnaires, tests, and interviews. The instruments used in this study were learning style questionnaires, shape and space content PISA test questions, and interview guidelines. The results showed that the achievement of the characteristics of the sixth spatial-visual abilities of the subjects differed. Students with a visual learning style can meet the characteristics of pattern search, conceptualization, problem-solving, and imagination in full. Students with an auditory learning style can meet the characteristics of conceptualization, problem-solving, and imagination completely but are unable to meet the characteristics of pattern search. Students with kinesthetic learning styles meet the characteristics of problem solving and imagination but are unable to meet indicators on the characteristics of pattern search and conceptualization. This can be seen from the results of solving the questions given and interviews conducted on the research subjects.
