Abstract

This study investigated the effect of Problem-Based Learning (PBL) on students’ mathematical problem-solving skills in Systems of Linear Equations in Two Variables (SPLDV), a contextual algebra topic that has received limited empirical attention in Indonesian junior high schools. Using a posttest-only control group design, the study involved 63 Grade VIII students of State Junior High School 2 Ngoro. The experimental group learned through PBL, while the control group received conventional instruction. The experimental group achieved a significantly higher posttest mean (78.12) than the control group (p < 0.05). The effect size (Hedges’ g = 1.14) indicated a very high effect, suggesting that PBL is particularly effective for improving students’ problem-solving skills in contextual SPLDV learning.

Abstract

Exponential functions pose conceptual challenges for secondary students due to their abstract nature. This quasi-experimental study investigated the effect of GeoGebra-based instruction on Grade 10 students’ conceptual understanding in two Indonesian senior high schools (N = 132). A validated four-item essay test (r > 0.219; Cronbach’s Alpha = 0.71) was administered before and after instruction. Mann–Whitney U analysis showed a significant difference in posttest conceptual understanding between the GeoGebra and conventional groups (p < .001), with a moderate-to-large effect size (r = 0.44). These results provide classroom-based empirical evidence that dynamic visualization through GeoGebra strengthens students’ conceptual understanding and supports its structured integration in conceptually demanding mathematics topics.

Abstract

This research aims to determine the creative thinking ability of students in arranging and solving contextual problems on arithmetic sequence. This research is a descriptive quantitative study through a Lesson Study framework with a subject of 18 students of the Mathematics Education study program at the Islamic University of Lamongan. The instruments in this study include attitude assessment sheets used to measure student activity in participating in learning and Student Worksheets used to measure students' creative thinking ability in arranging and solving contextual problems on arithmetic sequences. The results of the analysis show that the average score of student activities during learning is 85.13% while the average score of students' creative thinking ability is 71.875% in the Enough category.

Abstract

This research examines the influence of nanoparticles in the distribution of drugs in healthy blood flow on linear, angular velocity and blood temperature. Construction and simplification of a blood flow model based on boundary layer equations, dimensionless variables, stream functions, and similarity variables. The initial step is to establish a dimensional blood flow model. Using dimensionless variables, the equation is simplified into a dimensionless equation. A similarity equation is generated by converting the non-dimensional equation. The nanoparticles used are . At the linear velocity and temperature of blood flow  is in the highest position. At the angular velocity of blood flow, the position of blood flow with   nanoparticles is in the uppermost position. This research is used to estimate the velocity and temperature of blood flow with the influence of nanoparticles as drug distribution.

Abstract

The purpose of this study is to develop collaborative learning-based learning resources and their impact on students' capacity for critical thought. This study used a combination of methods, namely development research (R&D) with Thiagarajan 4D model and experimental research. Data was collected through observations, questionnaires, tests, and interviews. The validity coefficients for the Teaching Module, worksheet, and test were 3.80, 3.80, and 3.70, respectively. Observations showed that 96% of the learning tools met practical criteria. The tools were effective, with 93% of student activities rated very good, 96% of students giving positive responses, and 85% achieving learning completion. A t-test (sig = 0.007) confirmed the collaborative learning tool based on LSLC significantly enhanced students' critical thinking skills.

Abstract

This research examines whether the multiplication abilities of third-grade students in Pamekasan improve before, during, and after using JAMED media for mathematics instruction. The study aims to assess the students' multiplication skills across these three stages, analyzing any observed improvements. The research employs a single subject experimental method with an A-B-A design, using action tests for data collection. The subject is a third-grade student with the initials AW. Findings show that the student’s multiplication ability was very low in the initial baseline (A1), improved to a sufficient level during the intervention (B), and reached a high level in the final baseline (A2). This indicates a significant positive impact of JAMED media on the student's multiplication skills.

Abstract

This study discusses the role of mathematical literacy as the main competency that cadets need to have in the field of maritime education. Through a systematic literature review (SLR), the mathematical literacy competencies needed by cadets in the maritime field are navigation, problem solving, use of modern technology, operational management, critical and logical thinking, and accurate data-based decision making. This systematic review provides an illustration of literacy mastery Mathematics not only supports cadets' understanding of basic maritime concepts, but also improves cadets' abilities in dealing with challenges or unexpected situations on board ships and while at anchor. Therefore, developing mathematical literacy must be a priority in cadet education and training programs to produce graduates who are competent and ready to face the complexity of the global maritime industry.

Abstract

This study employs the Hungarian Algorithm to optimize the sandblasting project scheduling at PT. Prima Saka Engineering. Five workers (P1-P5) with different specializations were assigned five tasks: surface preparation (T1), exterior sandblasting (T2), interior sandblasting (T3), primer application (T4), and final quality inspection (T5). The goal was to reduce overall completion time, with each worker being assigned to only one task. The methodical steps comprised matrix building, reduction, and optimality testing. The Hungarian Algorithm generated an optimal assignment with a minimal total time of 1,128 hours, saving 222 hours (16.4%) compared to the previous 1,350-hour method. This study demonstrates that the Hungarian Algorithm provides a mathematically optimal and practically applicable framework for strategic resource allocation and project management.
