Abstract

Atherosclerosis is a leading cause of coronary heart disease. This study analyses how elliptically shaped stenoses alter blood-flow velocity in coronary arteries. The governing equations are discretised with the finite-volume method, coupling pressure and velocity through the SIMPLE (Semi-Implicit Method for Pressure-Linked Equations) algorithm and accelerating convergence with the Successive Over-Relaxation (SOR) technique. A weighted Gauss–Seidel iteration whose over-relaxation factor ( in this work) damps low-frequency error modes, cutting the number of iterations needed for residuals to fall below 10⁻⁴ by roughly 40 % compared with the standard Gauss–Seidel scheme. Simulations of 30 %, 50 %, and 70 % constrictions were carried out in MATLAB R2013a and ANSYS Fluent. Quantitative and qualitative cross-validation of the two software packages confirmed consistent velocity and pressure fields, though minor discrepancies arose from differing numerical schemes and model assumptions, underscoring the need for experimental verification. The highest centre-line velocity occurred at 70 % stenosis—0.72075 m/s in MATLAB versus 0.90 m/s in Fluent—while the lowest was recorded at 30 %. Velocity–pressure profiles showed that increasing inlet velocity or degree of narrowing elevates velocity but decreases pressure, with the largest drop (11492.4 Pa in MATLAB; 11747.32 Pa in Fluent) again at 70% stenosis. Study limitations include modelling blood as a Newtonian fluid and idealising arterial geometry; future work should incorporate non-Newtonian rheology and patient-specific shapes to enhance physiological accuracy.

Hasil analisis korelasi menunjukkan terdapat hubungan yang positif antara kepercayaan diri dan kemampuan pemecahan masalah matematis. Kesimpulan dari penelitian ini adalah semakin tinggi tingkat kepercayaan diri siswa, maka semakin baik kemampuan mereka dalam menyelesaikan soal-soal matematika secara problematis. Implikasi dari temuan ini menunjukkan pentingnya strategi pembelajaran yang tidak hanya fokus pada aspek kognitif, tetapi juga afektif siswa, seperti penguatan rasa percaya diri guna mendukung keberhasilan akademik, khususnya dalam pembelajaran matematika. Abstract Mathematical problem-solving ability is one of the essential competencies students must possess, and self-confidence is believed to significantly contribute to its achievement. This study aims to determine the correlation between self-confidence and junior high school students’ mathematical problem-solving ability. The research employed a quantitative method with a correlational design. The subjects were 87 eighth-grade students at SMP Negeri 12 Jember during the even semester of the 2023/2024 academic year. Data were collected through a self-confidence questionnaire and a mathematical problem-solving test. Based on descriptive analysis, the average self-confidence score was 96.08, with the majority (74.71%) falling into the average category. The results of the correlation analysis showed a positive relationship between self-confidence and mathematical problem-solving ability. The conclusion of this study indicates that the higher the level of students’ self-confidence, the better their ability to solve mathematical problems. The implications of these findings highlight the importance of learning strategies that focus not only on cognitive aspects but also on students’ affective domains, such as enhancing self-confidence to support academic success, particularly in mathematics learning.

Abstract

The phenomenon of students not being used to solving higher order thinking questions often occurred in one of the Islamic Senior High School in Sidoarjo. Therefore, this research aims to describe the profile of students' problem-solving in overcoming HOTS questions based on the self-efficacy. The research subjects were three selected students of XI-IPA class who were categorized into low, moderate, or high self-efficacy based on self-efficacy questionnaires and had good communication skills. The data were collected through tests, triangulated by interviews and analyzed using Polya's problem-solving indicators (unerstanding the problem, devising a plan, carrying the plan, and looking back). The results show that: 1) Students with low self-efficacy able to solve an “analyze” problem eventhough without looking back and solve the “evaluate” problem through all of the stages. Eventhough, he need help to work on the “creative” problem; 2) Students with moderate self-efficacy able to solve an “analyze” problem through all stages. However, while working on evaluate and creative problem, he could only complete the stages of understanding the problem, devise an incomplete plan and never try to carry out the plan; 3) Students with high self-efficacy can solve the problem on analyze, evaluate, and create in a complete stage. Teachers must become accustomed to asking HOTS questions to students in order to increase student self-efficacy and problem-solving abilities.

Abstract

Proses berpikir kreatif siswa dapat diketahui dengan cara memberikan siswa masalah open-ended. Penyelesaian soal open-ended memerlukan kemampuan pemecahan masalah yang berpengaruh terhadap upaya seseorang untuk dapat menyelesaikan masalah yang dihadapi. Kemampuan seseorang untuk menghadapi tantangan atau kesulitan biasa disebut dengan Adversity Quotient (AQ). Tujuan dari penelitian ini adalah untuk mendeskripsikan proses berpikir kreatif siswa climber, camper, dan quitter dalam pemecahan masalah open-ended. Jenis penelitian ini adalah deskriptif kualitatif. Pengumpulan data dilakukan dengan memberi angket ARP, tes open-ended, dan wawancara. Berdasarkan hasil analisis data disimpulkan bahwa siswa climber melakukan keempat tahapan proses berpikir kreatif yaitu tahap persiapan, tahap inkubasi, tahap eliminasi, dan tahap verifikasi. Siswa camper hanya melakukan tiga tahapan proses berpikir kreatif yaitu tahap persiapan, tahap inkubasi, dan tahap eliminasi. Siswa quitter hanya melakukan dua tahapan proses berpikir kreatif yaitu tahap persiapan dan tahap inkubasi, sedangkan tahap eliminasi tidak dapat terpenuhi karena hanya dilakukan pada salah satu dari yang ditanyakan pada soal.
