Pemodelan Matematika Aliran Darah Pada Arteri Perifer Akibat Pemasangan Stent
Full text linkPeripheral arterial disease is a disease that occurs due to narrowing of peripheral arteries caused by plaque buildup. If left too long, this disease can cause pain in the limbs and even have to be amputated. One way to treat PAP is by performing stenting or better known as angioplasty. Angioplasty is performed with the aim of opening the narrowed blood vessels so that blood flow can be normal again. Mathematical modeling is a science that can be used to simulate problems in the real world into mathematical models. Mathematical modeling can form a model that describes the state of blood flow in the peripheral arteries in accordance with the conditions and important factors in it. In this study a mathematical model of blood flow was built in the peripheral arteries to determine the effectiveness of stent placement obtained from the momentum equation and solved using the finite element method
UPAYA MENINGKATKAN HASIL BELAJAR IPA PADA KONSEP SISTEM PENCERNAAN MAKANAN MELALUI MODEL PEMBELAJARAN KOOPERATIF TIPE STAD PADA SISWA KELAS VIIIC SMPN 2 JEMBER TAHUN AJARAN 2019/2020
Full text linkAbstract: A cooperative model learning strategy of STAD (Student Teams Achievement Divisions) is a learning model through a cooperatives learning approach that emphasizes on activities and interactions between students to motivate and assist with learning materials to achieve maximum achievement. The purpose of this research was an increase the result of the 8th grade students science study of SMPN 2 Jember. This research method was a qualitative approach. This kind of research was class action research. The class action in this study was done with 2 cycles. The results were by taking a research subject of 8th grade students of SMPN 2 Jember. From tests for study results on cycle one gets an average of 68,75% become 75,50% while on cycle two is average 75,50% become 87,25%. From the rise in average value, the use of STAD (Student Teams Achievement Divisions) cooperative learning methods increases the students learning result to science lessons

IDENTIFIKASI GEOMETRI BIDANG PADA POLA MOTIF KAIN TENUN SOLOK BANYUWANGI
Full text linkAbstract: A culture is born from the local community so as to produce works that become the characteristic of the culture. This culture is rooted and develops over time. One result of cultural work is Banyuwangi solok weaving. Education appreciates local culture in order to participate in preserving through the teaching and learning process. Weaving Solok Banyuwangi can be included as a medium for student learning in schools. Mathematics is one branch of science that studies symbols with logical reasoning. So there are estimates of the mathematical elements found in the Banyuwangi solok weaving motif. Mathematical elements found in Banyuwangi solok weaving include points, lines, triangles, quadrilaterals, hexagon, folding symmetry, rotary symmetry, congruence and similarity.

PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE STAD TERHADAP HASIL BELAJAR FISIKA DI SMK NEGERI 5 JEMBER
Full text linkCooperative learning is a learning model that involves students to be able to actively participate in the learning process through the formation of small groups. One type of cooperative learning model is the Student Team Achievement Division (STAD) type. This study aimed to determine the effect of the STAD type cooperative learning model on physics learning outcomes of grade X students at SMK 5 Jember. This research is included in experimental research. The research design used was a post test only design. Data analysis technique used independent sample t-test (parametric test) and one way anova. The results showed that the significant value of the independent sample t-test was 0,000 (α<0,05) which means that the average physics scores of the experimental class students were greater than control class students. Thus, the STAD type cooperative learning model has a significant effect on learning outcomes in physics at SMK 5 Jember.

MENINGKATKAN HASIL BELAJAR MATEMATIKA SISWA MELALUI MODEL KOOPERATIF TWO STAY TWO STRAY (TSTS) TAHUN PELAJARAN 2019/2020
Full text linkAbstract: The success of a lesson can be measured by the achievement of student learning outcomes. Based on the preliminary test, it was found that 22 students (73.3%) were still under the KKM or who scored below 70. To improve learning outcomes, in this study the Two Stay Two Stray (TSTS) cooperative model was used. This type of research is classified as Classroom Action Research (PTK) with the implementation stages referring to the Kemmis and Taggart models. This research was planned in two cycles, including planning, action, observation and reflection. The subjects of this study were students of class VIIB Bangsalsari Junior High School 2019/2020, totaling 30 students. The test and observation method was used for data collection techniques, while the data analysis technique used comparative descriptive analysis (comparison) by comparing the results of pre-cycle, cycle 1 and cycle 2 and was calculated using a simple statistical formula. The results showed that the students' average score in the pre-cycle, cycle I and cycle II was 57.03; 71.97; and 85.57. Completeness of learning outcomes increased from 26.67% (8 of 30 children); 66.67% (20 of 30 children) and 90.00% (27 of 30 children). It can be concluded that the learning outcomes of class VIIB students of SMPN 3 Bangsalsari for the 2019/2020 academic year through the TSTS cooperative model can improve.

PENGARUH MICROWAVE ASSISTED PADA KURVA HISTERISIS MULTI DOMAIN BAHAN FEROMAGNETIK NIFE
Full text linkBahan alloy NiFe merupakan salah satu bahan feromagnetik yang memilki tekstur kuat dengan nilai anisotropi magnetik dan medan koersivitas besar. Kurva histerisis bahan NiFe ini menghasilkan medan koersivitas yang besar dalam golongan hard magnet. Penelitian ini mengkaji pengaruh dari microwave assisted pada kurva histerisis bahan NiFe dalam bentuk ellipsoid. Pengaruh microwave assisted membantu untuk mengecilkan medan koersivitas sehingga mengalami pembalikan magnetisasi semakin cepat untuk kembali pada posisi awal. Hasil simulasi pada ukuran 50 nm struktur multi domain dengan memberikan frekuensi 20 GHz dan amplitudo 100 mT diperoleh medan koersivitas sebesar 80 mT sedangkan pada frekuensi 200 GHz dan amplitudo 1000 mT diperoleh medan koersivitas sebesar 55 mT. Pengaruh dari microwave assisted yang dipengaruhi terjadi perubahan medan koersivitas yang semakin kecil.
