Abstract

This study aims to analyse the mathematical creative thinking abilities of junior high school students on the subject of curved-sided shapes: spheres. Creative thinking abilities were analysed based on four indicators, namely fluency, flexibility, originality, and elaboration. This study used a qualitative descriptive method with ninth-grade students at Sidoarjo State Junior High School as the subjects. The instrument used was an essay test consisting of four questions designed to explore students' creative thinking abilities. The results showed that the percentage of achievement for the fluency indicator was 80%, flexibility 70%, originality 70%, and elaboration 55%. These findings indicate that students have begun to develop good creative thinking skills, but there is still room for improvement, especially in the areas of flexibility and elaboration. These results can serve as a basis for teachers in designing learning activities that encourage the optimal development of students' creativity.

Abstract

Abstract. The travelling salesman problem is one of the classic optimisation problems that is widely applied in real life, such as in the distribution of goods, transportation route planning, and even the movement of industrial robots. This study aims to implement algorithms for solving the travelling salesman problem using two different programming languages, namely Pascal and C++, and to compare their performance in terms of effectiveness, memory efficiency, and execution speed. The methods used include weighted graph modelling, shortest path calculation, and the application of the Branch and Bound algorithm. The test results show that both programming languages produce identical optimal routes, namely 1 – 5 – 6 – 7 – 10 – 9 – 8 – 4 – 2 – 3 – 1 with a minimum total distance of 196. The Pascal programme has the advantage of a simple syntax structure and low memory usage (±356 KB), while C++ excels in execution speed (0.09466 seconds) despite having a larger output file size (±1.26 MiB). This difference in performance indicates that Pascal is more suitable for educational purposes and small-scale applications, while C++ is superior for complex applications and modern system integration needs. Thus, the TSP algorithm can be implemented effectively using either Pascal or C++, and the choice of programming language should be tailored to the context of the requirements.

Abstract

This study aims to implement PowerPoint-based image media to improve students' mathematical problem-solving skills. The subjects of this study were 30 students in class VII-2 of SMP Negeri 1 Tilongkabila, consisting of 12 boys and 18 girls. The research instrument was the results of the students' scores on a mathematical problem-solving test on data and diagrams. The data analysis techniques in this study were teacher observation, student observation, and mathematical problem-solving ability tests. This study used the action research method, with research procedures including planning, action, observation, and reflection. The research consisted of two cycles. The results of the research in cycle I showed that the results of observations of teacher activities only reached 66.67%, and student activities 58.33% with good criteria, and the level of students' mathematical problem-solving skills that were complete was only 14 students or 46.67%, while there were 16 students or 58.33% who were not yet complete. Because the success indicator of at least 80% was not achieved, the research continued to cycle II. In cycle II, the results of observations of teacher activities were 94.45% and student activities were 88.89% with good and very good criteria, and the level of students' mathematical problem-solving skills was 26 students or 86.67%. It is concluded that the implementation of PowerPoint-based image media can improve students' mathematical problem-solving skills.

Abstract

Penelitian ini bertujuan untuk mengembangkan pemahaman mendalam mengenai pemodelan dan analisis kurva parametrik melalui pendekatan teoritis dan visual menggunakan perangkat lunak GeoGebra. Kurva parametrik merupakan representasi matematis yang menggambarkan lintasan dalam bidang dua dimensi atau tiga dimensi dengan memanfaatkan satu atau lebih parameter bebas. Studi ini dimulai dengan kajian teoritis yang menguraikan dasar-dasar persamaan parametrik, termasuk bentuk umum kurva, sifat diferensialnya, serta konsep turunan pertama dan kedua untuk menentukan karakteristik seperti titik stasioner, kelengkungan, dan arah garis singgung. Selanjutnya, GeoGebra diimplementasikan sebagai alat bantu visual interaktif yang memungkinkan pengguna memodelkan kurva parametrik secara dinamis dengan manipulasi parameter secara real-time. Penggunaan GeoGebra memungkinkan analisis numerik yang akurat dan visualisasi grafik yang intuitif, sehingga mempermudah identifikasi titik ekstrem, simetri, serta perubahan bentuk kurva akibat variasi parameter. Metode penelitian mengintegrasikan kajian literatur, pengembangan model matematis, dan eksperimen visualisasi dengan GeoGebra untuk menghasilkan representasi kurva yang komprehensif. Hasil penelitian menunjukkan bahwa penggunaan GeoGebra secara signifikan meningkatkan efektivitas pembelajaran dan pemahaman konsep-konsep kalkulus diferensial serta geometri analitik terkait kurva parametrik. Selain itu, visualisasi dinamis membantu dalam menguji hipotesis matematis dan memperjelas hubungan antara parameter dan bentuk kurva. Studi ini juga menyoroti potensi aplikasi kurva parametrik dalam berbagai bidang seperti teknik, desain grafis, dan simulasi komputer. Kesimpulannya, integrasi pemodelan matematis dan visualisasi interaktif menggunakan GeoGebra merupakan metode yang efektif untuk mendalami analisis kurva parametrik sekaligus mendukung pengembangan metode pembelajaran matematika yang lebih inovatif dan aplikatif.

Abstract

The Fourth Industrial Revolution has significantly transformed various aspects of life, including education. The rapid advancement of digital technology requires society, including parents, to adapt, particularly with the implementation of online school enrollment systems. However, this situation creates challenges for parents unfamiliar with technology, leading to a digital divide. This study examines the factors influencing parents’ digital readiness at SMAN 2 Kabanjahe using the Technology Readiness Index (TRI), which evaluates individual attitudes toward technology through four dimensions: optimism, innovativeness, discomfort, and insecurity. A quantitative approach was employed with data collected from 80 parents via online questionnaires and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) in Smart-PLS 4.0. The results show an R² value of 0.615, indicating that 61.5% of the variance in digital readiness is explained by the model. Optimism has a significant positive effect, while discomfort has a significant negative effect. Conversely, innovativeness and insecurity do not significantly influence digital readiness. These findings highlight the applicability of the TRI model in assessing digital readiness, particularly in the educational context.
