Abstract

Pencarian solusi numerik dari sebuah model matematika adalah salah satu jenis penelitian yang diminati banyak peneliti khususnya di bidang fluida. Simulasi numerik sangat dibutuhkan dalam menggambarkan distribusi kecepatan dan temperatur dari aliran fluida yang melewati permukaan sebuah silinder eliptik. Dalam penelitian ini aliran fluida bersifat tak tunak dengan karakteriktik kental dan elastis. Model matematika yang didapat, didiskritkan dan disimulasikan dengan software Matlab. Berdasarkan hasil simulasi, diperoleh grafik berupa profil distribusi kecepatan dan temperatur fluida dari aliran fluida. Dari grafik yang diperoleh dapat disimpulkan bahwa nilai  sangat berpengaruh pada distribusi kecepatan dan temperatur aliran fluida, yaitu semakin besar nilai , maka kecepatan fluida yang mengalir semakin lambat dan temperatur yang dihasilkan semakin tinggi. Hal tersebut diakibatkan karena adanya gesekan antara fluida dengan permukaan silinder eliptik.

Abstract

Fluida merupakan salah satu topik penelitian di bidang matematika terapan yang banyak digunakan khususnya dalam proses industri. Pada industri minyak lepas pantai, dibutuhkan peran matematika dalam perhitungan distribusi fluida pada permukaan alat yang bekerja untuk dikembangkan lebih lanjut pada bidang teknologinya. Dalam penelitian ini, distribusi panas yang mengalir pada permukaan benda dipengaruhi oleh variasi nilai sumbu mayor. Nilai distribusi fluida disimulasikan ke dalam bentuk profil distribusi panas yang didapatkan dari model matematika dan diselesaikan secara numerik dengan Skema Beda Hingga. Semakin besar nilai sumbu mayor yang diberikan, maka distribusi panas yang dihasilkan semakin kecil. Hal tersebut disebabkan, distribusi panas pada permukaan benda dipengaruhi oleh besarnya luas penampang benda.

Abstract

The learning model during the Covid-19 pandemic has reduced students' mathematical communication because students are very dependent on gadget facilities. In this study, researchers used a learning model, namely Cooperative Auditory Intellectually Repetition (AIR). This study aims to determine the effect of Cooperative AIR learning model on students' mathematical communication on the material of System of Linear Equations of Three Variables (SPLTV) at SMAN 1 Driyorejo Gresik. This learning model is a quantitative research with data collection techniques that apply the test process using normality test, homogeneity test, and continued with hypothesis testing. The test instrument used was a post-test on students' mathematical communication as many as two questions. Based on the calculation result of students' mathematical communication test, it was found that students' mathematical communication using Cooperative AIR learning model was better than students' mathematical communication using Cooperative Jigsaw learning model with  or  rejected, so it can be concluded that there is an effect of Cooperative AIR learning model on mathematical communication of class X students at SMAN 1 Driyorejo Gresik on SPLTV material.

Abstract

Derivatives of functions are one of the teaching materials of the Calculus Course for the Electrical Engineering Study Program at PGRI Adi Buana University, Surabaya. This material is very important to study, especially for engineering students as a basis for mastering calculation concepts in subsequent courses. However, students still experience difficulties in mastering the concepts of the material and solving the questions given. The purpose of this research is to determine the level of difficulty students have in mastering the concept of derivative functions and to determine the causes of these difficulties. This research uses a descriptive qualitative method, where the researcher describes and explains in detail the problem of students' difficulties in studying derivatives of functions in the Calculus course. Data was taken from the results of the Quiz for students in the Electrical Engineering Study Program for the 2024/2025 academic year. The research results showed that 69% of students made Principle Errors (KP) and 32% made Calculation Errors (KH). So, it can be concluded that most students cannot remember existing rules, formulas or theorems and identify material concepts. Furthermore, it is hoped that the results of this research can be used as a basis for improving Calculus I learning, so that learning is more interesting and students are more enthusiastic in participating in the learning.

Abstract

The transformation geometry course is a mandatory course that studies the basic concepts of transformation geometry, including translation, reflection, rotation, dilation, and transformation composition. Transformation geometry courses cannot be separated from the activity of deductively deriving concepts, theorems and algorithms, so more skills are needed so that students can understand this course easily. Therefore, the transformation geometry course requires good and effective teaching materials which can encourage students to actively interact with each other and be able to understand the material effectively, namely in the form of textbooks. The method stages carried out in this research are needs analysis, preparation of textbooks, expert validation, revision of textbooks, trials and giving questionnaires and evaluation. The results of the student response questionnaire revealed that 80% of students stated that they strongly agreed with the use of this Transformational Geometry textbook and the results of student understanding were good, so the textbook developed was valid, practical and effective.

Abstract

Vortex-Induced Vibration (VIV) mitigation is a critical issue in engineering systems involving bluff bodies subjected to fluid flow. This study presents a numerical investigation of viscoelastic fluid flow over an elliptical cylinder as a passive control strategy to suppress vortex shedding. The governing continuity, momentum, and energy equations for an incompressible viscoelastic fluid are formulated and solved using an implicit finite difference method. The viscoelastic behavior of the fluid is incorporated through a nonlinear constitutive model, and the resulting system of equations is transformed into a dimensionless form to facilitate analysis. The study focuses on the effects of key parameters, including the viscoelastic parameter K, the Prandtl number P r, and the geometric aspect ratio a/b of the elliptical cylinder. Numerical simulations are performed using MATLAB to evaluate the resulting velocity and temperature distributions within the boundary layer region. The results indicate that increasing the viscoelastic parameter significantly reduces the peak velocity near the wall and weakens the velocity gradient, leading to a decrease in shear stress. In addition, higher viscoelasticity contributes to a thicker momentum and thermal boundary layer, which reduces the rate of heat transfer from the surface. Furthermore, variations in the Prandtl number and aspect ratio are found to influence the localization of thermal and momentum transport. Higher values of P r result in thinner thermal boundary layers and enhanced temperature gradients near the surface, while changes in a/b primarily affect the near-wall flow structure. Overall, the combined effects of viscoelasticity and geometric modification demonstrate a strong potential for attenuating vortex shedding and reducing the likelihood and intensity of VIV. These findings provide valuable insights for the design of engineering systems involving non-Newtonian fluids and flow-induced vibrations.
