<![CDATA[Abstract This study aims to examine the extent to which the Project-based Learning (PjBL) model impacts mathematics learning outcomes on the topic of length units for third-grade students at SDN 2 Bendanpete. The research employs a quantitative experimental method through a Pre-Experimental Design approach, specifically using a One-Group Pretest-Posttest Design. The data analysis techniques include prerequisite tests through normality testing and hypothesis testing using the Paired Sample T-Test. Data were collected through multiple-choice tests administered before (pretest) and after (posttest) the implementation of the Project-based Learning (PjBL) model. Instrument validation results indicated that 15 items were valid, and reliability testing showed a high reliability score with Cronbach’s α = 0.860. Data analysis through the t-test, resulting in a value of (-19.0), demonstrated a significant improvement in student learning outcomes, with the average posttest score (81.1) considerably higher than the average pretest score (51.4). These findings suggest that the application of the PjBL model effectively enhances student achievement in the topic of length measurement. It is expected that the outcomes of this research will provide new insights into the use of innovative instructional models to improve student learning achievement. Keywords: Project-based Learning; Learning Outcomes; Mathematics]]>

<![CDATA[The impact of boycotts against global brands has directly influenced the marketing approaches of fast-food companies such as KFC and McDonald’s. This study aims to identify the most effective marketing strategies that both companies can adopt in response to these challenges. The research utilizes a two-player game theory model with a mixed strategy approach, analyzed through matrix algebra—specifically involving calculations of cofactors, adjoints, and determinants. Data were collected via questionnaires distributed to 100 students at the University of Mataram, focusing on four key strategic variables: communication, promotion, innovation, and service. The response matrices were simplified using row and column dominance elimination before further analysis. The results show that KFC’s optimal strategy consists of a combination of 60% innovation and 40% promotion. In contrast, McDonald’s performs best with a balanced strategy, applying 50% promotion and 50% innovation. A game value of –12 indicates that McDonald’s holds a relative advantage in minimizing potential losses during the boycott period. This study contributes valuable insights into quantitative marketing strategy analysis using a mathematical framework.]]>

<![CDATA[This study was conducted with the aim of describing the forms of conceptual errors made by Mathematics Education study program students in solving set and function problems in real numbers, and analyzing the causes of errors made. The research method used was qualitative with descriptive method. The research subjects consisted of five students who were randomly selected, with the condition that they had taken related courses but still showed errors in working on problems. Data were collected through a questionnaire test designed to reveal students' conceptual understanding and analyzed using Kastolan's error classification. The results showed that procedural error was the most dominant type of error, with a percentage of 60%. Conceptual errors and technical errors each had a percentage of 20%. This finding shows that students still have difficulty in following the steps of solving problems coherently, understanding basic concepts, and performing calculation operations carefully. Therefore, improvement is needed in learning strategies that emphasize concept understanding, procedural accuracy, and technical accuracy]]>

<![CDATA[This study aims to analyze the effectiveness of the KOPSINU teaching aid in the Make a Match learning model for improving students' numeracy literacy. The research is based on the low numeracy literacy of Indonesian students, which is caused by less interactive learning methods and minimal use of teaching aids. A quantitative approach with a quasi-experimental posttest-only control group design was used. The subjects consisted of 60 seventh-grade students at SMP Islam Sultan Agung 4 Semarang, divided into experimental and control groups. The research instrument was a numeracy literacy test covering aspects of mathematization, symbolization, reasoning, and argumentation. The t-test results showed a significant difference between the two groups, with the experimental group scoring higher on the posttest. These findings indicate that the use of KOPSINU significantly enhances students' numeracy literacy by creating a more interactive, engaging, and motivating learning environment that helps students actively understand mathematical concepts.]]>

<![CDATA[Mumps is a contagious viral disease transmitted through respiratory droplets and close contact. It can cause symptoms like fever and salivary gland swelling. Despite the MMR vaccine, which offers partial protection, outbreaks persist, especially in college-aged individuals. Epidemiological models can aid in identifying effective prevention strategies for controlling mumps transmission. This paper proposes a mathematical model for mumps spread, considering quarantined individuals and complications. A global stability analysis of the mumps transmission model was performed, considering mortality and quarantine subpopulation. The Disease Free Equilibrium and Endemic Equilibrium Point are globally stable, confirmed by Lyapunov functions. Sensitivity analysis of the basic reproduction number shows that reducing birth rates and contact between infected and susceptible individuals effectively minimizes the infected population. However, increasing the natural death rate can reduce the total population, which may lower infections, but poses potential social and economic challenges for decision-makers.]]>
