Abstract

This study aims to improve the mathematics learning outcomes of ninth-grade students (Class IX G) at SMP Negeri 2 Mataram in the 2023/2024 academic year through the implementation of the Problem-Based Learning (PBL) model. The subjects of this study were 39 students from Class IX G. This research employed a Classroom Action Research (CAR) design, conducted over two cycles. Each cycle consisted of four stages: planning, action, observation, and reflection. Data were collected through learning outcome evaluation tests administered at the end of each cycle and analyzed using a quantitative descriptive approach. The results of the analysis showed an improvement in students’ learning outcomes on the topic of curved-surface solid geometry after the application of the PBL model. This improvement was evidenced by an increase in the percentage of students who achieved the minimum mastery criteria (KKM), from 76.51% in the first cycle with an average score of 76.51 to 87.18% in the second cycle with an average score of 83. These findings indicate that the implementation of Problem-Based Learning effectively enhances both the average learning outcomes and the proportion of students who meet the mastery criteria.

Abstract

Metric dimension is an important concept in graph theory that is widely used in various fields, including navigation, network localization, and network design. The concept of metric dimension is the concept of determining the least marker vertex so that each vertex in the graph is distinguished from each other. The purpose of this research is to determine the metric dimension of the pinwheel subdivision graph ????1+????????3. The type of research used is pure research. By using graph structure and vertex distance analysis, this paper shows the value of the metric dimension of the subdivision graph ????(????,????), specifically on the pinwheel graph ????=????1+????????3 for 2≤????≤4. The results show that the metric dimension of the pinwheel subdivision graph ????1+????????3 is one less than the metric dimension of the pinwheel graph before subdivision, ????????????(????(????,????))=????????????(????)−1.

Abstract

This study aims to describe the ability to solve mathematical problems on two-variable linear equation system material based on the locus of control in grade VIII students. This study used qualitative methods to obtain a sample of 72 students using purposive sampling. Data collection techniques use locus of control questionnaire instruments and problem-solving ability test questions. The results of this study showed that students with a strong external locus of control were only able to reach a step of understanding the problem. Meanwhile, students with a balanced internal and external locus of control can reach two steps namely, understanding the problems and devising a strategy. This happens because, students with a strong external locus of control, as well as students with a balanced internal and external locus of control, are less trying and less active in seeking information related to the problems at hand, and are easily influenced by others. Meanwhile, students with a strong internal locus of control can reach three steps namely, understanding the problems, devising a strategy, and carrying out the strategy. This happens because students have a strong internal locus of control easily satisfied with the results they get with the effort they make.

Abstract

Metode numerik digunakan untuk memecahkan persoalan matematika dalam bentuk pengintegralan dinamakan dengan integrasi numerik. Integrasi numerik salah satunya adalah metode simpson yang dibagi menjadi dua yaitu simpson dan simpson . Dengan pesatnya perkembangan ilmu pengetahuan dan teknologi memberikan perangkat software membantu memecahkan permasalahan yang membutuhkan waktu pengerjaan yang cukup lama dapat dilakukan dengan cepat.  Program software berbasis pascal merupakan salah satu perangkat lunak (software) yang kreatif untuk menyelesaikan permasalahan matematika dengan cepat. Tujuan dari penelitian ini adalah untuk mengetahui efisiensi integral numerik metode simpson  dan simpson  menggunakan program software berbasis pascal. Setelah membuat source code dan diimplementasikan kepada fungsi eksponensial, fungsi polinomial dan fungsi trigonometri akan mendapatkan nilai hampiran, galat relatif, dan waktu pengerjaan pada iterasi  dan eksak yang berbeda. Berdasarkan hasil penelitian dan pembahasan diperoleh bahwa metode simpson  lebih efisien digunakan untuk mencari nilai hampiran dari integral fungsi eksponensial, polinomial dan trigonometri dengan rentang . Waktu eksekusi program software pascal pada metode simpson  lebih kecil dibandingkan dengan waktu eksekusi pada metode simpson  yaitu pada integral fungsi eksponensial sebesar  mili detik, pada integral fungsi polinomial sebesar  mili detik dan integral fungsi trigonometri  mili detik sedangkan pada metode simpson  waktu eksekusi yang diperlukan terhadap fungsi eksponensial sebesar  mili detik, integral fungsi polinomial sebesar  mili detik dan integral fungsi trigonometri sebesar  mili detik.

Abstract

The learning process of elementary schools in Suntalangu village has not fully integrated digital technology in the learning process, so innovative technology-based learning has not run optimally. Some of the reasons for this are that schools do not have libraries and laboratories, so students and teachers have limited access to adequate learning resources. Based on this, to improve the quality of mathematics learning in Elementary Schools (SD) Gugus Suntalangu can be done using website-based digital media. Specifically, this media is expected to help visualize the material, increase student interaction, and improve understanding of concepts. Another goal is to improve teachers' ability to integrate digital technology into the learning process and implement innovative digital-based learning approaches. The method of implementation is by holding technology adaptation training for teachers in the suntalangu cluster. The service activity was held at SDN 4 Suntalangu, East Lombok, on May 28, 2025, with 20 teachers from 14 elementary schools as participants. This service has succeeded in improving teachers' ability to use website-based digital media. This learning media has proven to be relevant and effective in helping teachers and students in elementary schools.

Abstract

The problem of scheduling learning activities at SMKN 4 Mataram is the same teachers are scheduled at the same time in two class or more. The coloring graph concept can be used to find out the causes of the scheduling problems at SMKN 4 Mataram. Based on result of the application coloring graph concept generated  to the chromatic number is 23 with slots number is 46 which is smaller than 55 or  time slots  at SMKN 4 Mataram. Because slots of chromatic number are smaller than the time slots at SMKN 4 Mataram, it is known that the causes of scheduling problems at SMKN 4 Mataram are wrong scheduling way. One of solution to this problem is to compile a schedule based on the coloring graph concept by mapping 419 subjects with 84 teachers and 55 time slots spread from Monday to Saturday. In applying the coloring graph concept, the Largest Degree Ordering (LDO) algorithm is used. It is because this algorithm is simpler than other algorithms.

Abstract

This research aims to develop a learning media based on Tailwind CSS and GeoGebra in the topic of Transformation Geometry for ninth-grade students at MTsN 2 Mataram. The background of this study is students’ difficulties in understanding transformation geometry concepts due to their abstract nature and the limitations of conventional learning media, which tend to be less interactive. The method used in this study was Research and Development (R&D) with ADDIE (Analysis, Design, Development, Implementation, Evaluation) as the development model. The research sample consisted of ninth-grade E class students of MTsN 2 Mataram. The developed learning media was evaluated for its feasibility by media experts and tested with students. The validation results showed that the developed learning media met the feasible criteria with a feasibility percentage of 74,6%. The practicality test through student questionnaires also indicated a very practical category with a practicality percentage of 93,65%. Therefore, the learning media based on Tailwind CSS and GeoGebra is considered feasible and practical to be used as a learning aid in teaching transformation geometry at schools.
