Abstract

Mathematics plays a very important role in various aspects of human life. Furthermore, learning mathematics can enhance logical, critical, systematic thinking, and problem-solving abilities, which are highly beneficial in daily life. This research aims to analyze the reasoning and problem-solving abilities of students at Mts Nurul Huda Mangaran in Situbondo through the completion of PISA 2012 questions, which the students had not encountered previously. The research approach used is qualitative, allowing the researcher to directly communicate with the respondents to assess the mathematical abilities of the students. Based on the data analysis conducted on 21 respondents, it is evident that the majority of students cannot answer these questions correctly. The challenge they face is difficulty in interpreting the issues presented in the questions. In questions related to inductive reasoning, students are capable of providing answers. However, for deductive reasoning questions, students still struggle to solve the problems presented in the questions.

Abstract

There is a deadly cardiovascular disease that can cause swelling of the Abdominal Aorta. This disease is known as Abdominal Aortic Aneurysm (AAA). AAA is believed to be a degenerative process caused by genetic factors, gender, body weight, and age. Changes in collagen and elastin in the aortic wall are the cause of the degeneration process. Therefore, it will cause dilatation of the aortic wall. Swelling of the aortic blood vessels will affect the blood flow velocity in the aortic blood vessels. This research aims to analyze the velocity of blood flow in the Abdominal Aortic Aneurysm based on swelling diameter, proximal neck length, and aneurysm channel length using Computational Fluids Dynamics (CFD). The blood flow velocity was modeled using mathematical language based on mass continuity equations and momentum equations.  Then the finite volume method was one method to solve the mathematical model. MATLAB and ANSYS FLUENT software were used to simulate the velocity of blood flow analysis. The results of the research were shown that the larger the diameter and swelling channel length, the smaller the velocity of blood flow produced. Then, the greater the length of the proximal neck, the faster the resulting blood flow will be.

Abstract

PISA (Program for International Student Assessment) is an international assessment designed to measure students' literacy abilities in various disciplines, including science. This research aims to analyze the scientific literacy abilities of students at MTS Nurul Huda Situbondo in solving PISA Science questions. The research method used is data analysis from the results of the PISA Science test given to students. The data described includes test results based on problem-solving and reasoning assessment rubrics. The research results show that most students need help solving these questions, such as understanding questions well, misinterpreting images, applying scientific knowledge, and relating them to real life. The results of the analysis also show that there is significant variation in abilities among students. The results of the Kruskal Wallis-H test show a p-value <0.05, which means there is a substantial difference between the 3 dependent variables. Some students demonstrate scientific literacy in analyzing and solving PISA science questions, while others still need further assistance. The research results will provide insight into the challenges in solving PISA Science questions by students and improving science education at MTS Nurul Huda Situbondo. Understanding and overcoming these obstacles can prepare students to compete globally, especially in science.
