Abstract

Mathematical representation translation plays an important role in the learning process, as it connects different forms of representation. This study aims to describe the translation of mathematical representations by students, specifically translating verbal representations into graphs, in solving contextual problems related to quadratic function graphs. The choice of this topic is based on the common difficulties students face in drawing graphs and understanding related problems. The subjects of this study were six ninth-grade students from MTsN 1 Kota Malang, grouped into three categories based on their mathematical proficiency: high, medium, and low. This research uses a qualitative approach, with tests and interviews as data collection instruments. The subjects were selected using purposive sampling. Data analysis was conducted through data triangulation involving data reduction, presentation, and conclusion drawing. The results show that, in the Unpacking the Source stage, students with high and medium proficiency were more accurate in graphing than students with low proficiency. At the Preliminary Coordination stage, high and medium proficiency students were able to perform calculations to determine the function formula, while low proficiency students struggled to identify the appropriate steps. At the Constructing the Target stage, high and medium proficiency students were able to plot the graph correctly according to the obtained coordinates, while low proficiency students had difficulty placing the coordinates. This study indicates that the translation of representations is closely related to students' conceptual understanding and problem-solving abilities.

Abstract

The rainbow connection number is a graph parameter that integrates edge colouring and graph connectivity. A connected graph is said to be rainbow connected if every pair of vertices is joined by a path whose edges have distinct colours, and the rainbow connection number represents the minimum number of colours required to satisfy this property. This study aims to provide a comprehensive and systematic analysis of research developments related to rainbow connection numbers in graphs. The method employed is a systematic literature review of reputable international journals and nationally accredited publications. The analysis covers fundamental definitions, known values for various classes of graphs, relationships with structural parameters such as diameter, minimum degree, and connectivity, as well as computational complexity and several important variants, including strong rainbow connection, rainbow vertex-connection, and total rainbow connection. The results indicate that the rainbow connection number is strongly influenced by graph structure, with diameter serving as a natural lower bound and connectivity contributing to tighter upper bounds. Furthermore, determining the exact value for general graphs is computationally intractable, motivating the use of approximation and heuristic approaches. This study also identifies research gaps, particularly in algorithmic development and the analysis of complex graph class, and highlights potential applications in communication networks and network security.

Abstract

This study investigates how effective rapid calculation training is in improving the basic math skills of Madrasah Ibtidaiyah (MI) teachers in West Sumatra. This research was conducted because teachers rarely use effective calculation strategies and there are no professional development programs specifically aimed at enhancing their basic math skills. A quantitative method was used with a single pretest-posttest group. The study involved 125 teachers from four Madrasah Ibtidaiyah located in West Sumatra, and 96 participants were selected using purposive sampling. Data were collected through rapid calculation tests administered before and after the training intervention. Paired-sample t-tests and the N-Gain index were used to analyze the collected data. The results showed a statistically significant improvement in participants' performance after the training, with a significance value of 0.000 (p < 0.05). In the posttest, the average score increased from 36.00 in the pretest to 67.27 in the posttest. In addition, the level of participant competence improvement is shown by an N-Gain value of 0.49. The results indicate that calculation training is effective in quickly improving the basic mathematics competence of MI teachers. These results also show that this type of training can serve as a feasible professional development program to enhance teachers' mathematics skills and improve the quality of mathematics learning in Madrasah Ibtidaiyah.

Abstract

This study aims to determine the effect of the Green Education–based Contextual Teaching and Learning (CTL) model on students’ mathematical literacy skills. The study is motivated by the low level of mathematical literacy among eleventh-grade students at SMA Negeri 2 Kerinci in relating mathematical concepts to real-life problems, particularly those associated with environmental issues. The research employed a quasi-experimental method with a randomized control only design. The population of this study consisted of all eleventh-grade students at SMA Negeri 2 Kerinci. The sample included class XIB as the experimental group, which received instruction using the Green Education–based CTL model, and class XIA as the control group, which received conventional instruction. The research instrument was a mathematical literacy test. The results revealed that there was a significant effect of the Green Education–based CTL model on students’ mathematical literacy skills. This is evidenced by the hypothesis testing results, which showed a significance value of 0.027 0.05, indicating that H₀ was rejected and H₁ was accepted. Therefore, students taught using the Green Education–based CTL model demonstrated better mathematical literacy skills than those taught through conventional learning. The implications of this study suggest that the Green Education–based CTL model can be used as an effective alternative learning model to improve students’ mathematical literacy skills, particularly in advanced statistics material.

Abstract

Pneumonia is a disease which is having similar symptoms like ISPA. It is probably that making many parents did not realize if their children severe Pneumonia. Because according to Indonesia ministry health, there was significant increasingly Pneumonia cases year by year from 2021 to 2024, in 2024 is a year with highest Pneumonia cases, almost 800.000 Pneumonia cases even BPJS report, budget for Pneumonia therapy is highest than other diseases. Then, we need to make a quick preventative action, one of them is optimal control with rapid test. Rapid test is needed in order to detect an individual severe Pneumonia. In order, the aim will success so we need to develop SEIR model with add a control of rapid test to the exposed class. The addition is needed because children have symptom acquiring a certainty Pneumonia infected or not so the therapy will be quick and correct. After that, we need to find the optimal control of rapid test and then to describe the effect of optimal control on the exposed, infected, and recovered classes. The parameters values need to input to the equations which was given a control and next, we have to calculate with used sweep method step forward-backward and with helped by MATLAB software obtain the final result. The result is with control the number individual infected Pneumonia decreasing since initial time till 100th days, meanwhile without control the number individual infected increase till 10th days and after that the plot becomes decrease till 40th days.
