Abstract

PT. Pertamina (Persero) is one of the providers of refueling services in Indonesia. The role of Fuel Oil (BBM) is very important in people's lives, so to meet fuel needs, this company has built a Public Fuel Filling Station (SPBU). Petrol stations are a means to distribute fuel oil. As one of the companies that provide fuel in Indonesia, this company must pay attention to the quality of service. One of the strategic petrol stations in Mataram City is the petrol station 54.832.12 Jl. Gajah Mada Pagesangan, Mataram City. The large number of pertalite refueling during peak times in the morning and evening at this petrol station resulted in queues, so a study was carried out on the optimal condition of petrol station services based on the number of noozles using the Monte Carlo simulation method, by modifying the generation of random numbers using the Linear Congruent Method (LCM) random number generation. The simulation is carried out based on the arrival time and service time taken every 3 minutes 100 times. By conducting simulations 500 times and as many as 10 activities, optimal conditions were analyzed based on the number of noozles. The results obtained show that as many as 4 noozles are needed on the pertalite motorcycle dispenser to get optimal conditions because the average remaining queue is close to 1, which is 1.51 vehicles, and the Pertalite Car dispenser is enough with 1 noozle, the average remaining queue is close to 1, which is 1.62 vehicles.

Abstract

This study aims to determine the influence of reflective thinking and self-confidence on the mathematical problem-solving ability of grade VIII students of SMPN 9 Mataram for the 2024/2025 academic year. This research is a quantitative research with an ex-post facto (comparative causal) research method. The population of this study is 163 students in grade VIII of SMPN 9 Mataram for the 2024/2025 academic year. The sample used was 55 people who were determined using the cluster random sampling technique. The instrument in this study used a reflective thinking test in the form of description questions, self-confidence questionnaires and problem-solving ability tests in the form of description questions. The results of the study showed that there was a positive and significant relationship between reflective thinking and self confidence on the mathematical problem-solving ability of grade VIII students of SMPN 9 Mataram with a contribution of 49,9%. The results of this research are expected to be an input for teachers to develop learning that encourages students to think reflectively and build confidence in solving math problems. For students, it is important to continue to practice reflective thinking skills and increase self-confidence to support the achievement of optimal learning outcomes.

Abstract

Duality in linear programming is an essential concept in optimization-based decision making. However, many undergraduate students still struggle to understand and solve duality problems, especially when converting primal to dual models and interpreting their results. This study aimed to explore the learning strategies used by fifth-semester students in solving duality problems. A qualitative case study approach was employed, involving 36 students from a mathematics education program. Data were collected through classroom observations, open-ended tasks, reflective writing, and interviews, and analyzed thematically. The findings revealed that most students (52.8%) used procedural repetition strategies, while others adopted conceptual elaboration (30.6%) and organizational strategies (16.6%). Students who used elaboration and organizational strategies demonstrated deeper conceptual understanding and greater problem-solving flexibility. These results suggest that procedural approaches still dominate, and instructional efforts should focus on fostering more reflective and meaningful learning strategies among students.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis faktor-faktor internal yang memengaruhi literasi matematika siswa di Indonesia melalui pendekatan Systematic Literature Review (SLR). Literasi matematika menjadi kompetensi penting dalam menghadapi tantangan abad ke-21, namun berbagai hasil studi menunjukkan bahwa capaian siswa Indonesia dalam literasi matematika masih tergolong rendah, sebagaimana tercermin dalam hasil asesmen nasional dan studi internasional seperti PISA. Dalam kajian ini, peneliti menelaah 20 artikel ilmiah yang diterbitkan antara tahun 2020 hingga 2025, yang diperoleh melalui pencarian sistematis pada basis data Google Scholar. Hasil analisis menunjukkan bahwa faktor internal yang dominan meliputi motivasi belajar, self-efficacy, minat terhadap matematika, gaya belajar, serta kemampuan metakognitif. Faktor-faktor tersebut berkontribusi secara signifikan terhadap pencapaian literasi matematika siswa. Temuan ini memberikan implikasi penting bagi pendidik dan pemangku kebijakan untuk merancang strategi pembelajaran yang responsif terhadap kondisi internal siswa guna meningkatkan literasi matematika secara lebih optimal.

Abstract

This study was motivated by the low level of students' understanding of mathematical concepts, which is partly due to the limited use of innovative learning media. The purpose of this research is to determine the effect of GeoGebra integration on students' conceptual understanding of three-dimensional geometry in grade XI at SMAN 1 Pringgasela in the 2024/2025 academic year. This research employed a mixed-methods approach with a concurrent embedded design, emphasizing the quantitative aspect. The sample consisted of two classes: the experimental class, which used the Problem-Based Learning model assisted by GeoGebra, and the control class, which used conventional learning. The posttest results showed that the average score of the experimental class was 82.71, while the control class scored 53.94. The t-test showed a significance value (2-tailed) of 0.000, which is ≤ 0.05, indicating a significant difference between the two groups. Furthermore, the effect size value of 2.32 falls into the large category, indicating that GeoGebra integration had a significant impact on improving students’ conceptual understanding. Thus, the use of GeoGebra has proven effective in enhancing the quality of mathematics learning, particularly in three-dimensional geometry topics.

Abstract

The purpose of this research is to describe the problem-solving abilities of students in linear equation systems of two variables (SPLDV) material with visual, auditory, and kinesthetic learning styles. This type of research is qualitative with a descriptive method. The instruments used in this research are learning style questionnaires, problem-solving ability tests, and interview guidelines. Subjects were taken from each learning style, with 2 students from each style being interviewed to deepen the data. The results of the study show that students with visual learning styles are able to meet all indicators of problem-solving abilities, namely understanding the problem, making a problem-solving plan, implementing the plan, and re-examining the solution obtained. Students with kinesthetic learning styles are only able to meet three indicators of problem-solving abilities, namely understanding the problem, making a problem-solving plan, and implementing the plan. Students with auditory learning styles are only able to meet one indicator, namely understanding the problem. This shows that the problem-solving abilities of students with visual and auditory learning styles are better compared to students with kinesthetic learning styles.

Abstract

This research aims to describe the mathematical problem-solving abilities related to sequences and series among XI grade students at SMAN 1 Sakra, considering gender differences. The research follows a qualitative descriptive approach, utilizing interview-based test questions as instruments. These questions will be analyzed based on Polya’s problem-solving indicators. From a total of 70 students, six were selected—three male and three female students—to represent different levels of mathematical problem-solving abilities: high, moderate, and low. The findings reveal that high-ability male students understand problems, plan and execute solutions (though with operational errors), and perform checks without writing conclusions. Moderate-ability male students partially meet the problem-solving criteria. Low-ability male students do not meet all the indicators. Among high-ability female students, understanding, planning, execution, and checking occur, but conclusions are missing. Moderate-ability female students also fall short in completeness and checking indicators. Low-ability female students only meet the understanding phase.
