Abstract

This article aims to examine the role of digital learning media in supporting mathematics learning that is aligned with the spirit of the Merdeka Curriculum. The research was conducted using the Systematic Literature Review (SLR) method on twenty scientific articles that discuss the use of digital media in learning mathematics at various levels of education. The results of the study show that digital learning media such as the Canva application, Wordwall, digital comics, animated videos, and educational games can significantly improve concept understanding, learning motivation, and student engagement. Digital media also supports the differentiated and contextual learning approach that is the main characteristic of Merdeka Curriculum. This study concludes that digital media is not only effective in conveying abstract material visually and interactively, but also encourages the development of students' 21st century skills, such as critical thinking, independence, and creativity. The findings are expected to be a reference for teachers, researchers, and policy makers in designing innovative and adaptive mathematics learning strategies in the digital era.

Abstract

This study aims to analyze students' difficulties in understanding algebraic concepts in the implementation of the Merdeka Curriculum. This type of research uses a descriptive research method with a qualitative approach. Data collection techniques include interviews, questionnaires, and three written tests. Based on the results of interviews and questionnaires conducted by teachers with the school principal and mathematics teachers, the school has implemented the Merdeka Curriculum despite limitations in resources. The Merdeka Curriculum contributes to teachers in terms of teaching modules and freedom in creativity in learning, although training is still needed. The results of the student questionnaire indicate that the majority of students have difficulty understanding algebra, especially in identifying variables, but the majority of students feel that classroom learning is interactive and enjoyable. Most students feel helped by the example questions provided by the teacher. The written test results show that students have difficulty with the use of positive and negative signs, coefficients, constants, algebraic operations, and determining variable values. This indicates that the majority of students have not yet achieved mastery of the algebra material. It can be concluded that the implementation of the independent curriculum at SMP IT Az-Zahira Khatulistiwa supports teachers in the algebra learning process through the use of teaching modules, but students still struggle to understand algebraic concepts due to the limited use of educational media, which is constrained by the school's facilities.

Abstract

The purpose of this study is to examine how deep learning influences students’ mathematical critical thinking skills. In mastering mathematics—which requires reasoning, analysis, and systematic review—critical thinking is essential to address the challenges of the 21st century. This research employs a quasi-experimental design using a pretest-posttest control group model. The subjects of the study were eighth-grade junior high school students, divided into an experimental group and a control group. The main instruments used were a mathematical critical thinking skills test and a learning activity observation sheet. The findings indicate that students who participated in instruction based on a deep learning approach showed a significant improvement in critical thinking skills compared to those who received conventional instruction. Unlike students who underwent standard learning methods, those exposed to deep learning strategies experienced a notable enhancement in their critical thinking abilities. Based on these findings, the implementation of deep learning is recommended more broadly in mathematics classroom instruction.

Abstract

This study uses a qualitative method with a literature review approach to examine the effectiveness of the two-phase method in solving linear programming problems. The two-phase method is one of the techniques in linear programming used when the objective function does not have a feasible initial solution directly. Through the exploration and analysis of various scientific literature sources from 2019 onwards, this study finds that the two-phase method can systematically provide optimal solutions, especially in complex problems with multiple constraints. Previous research has shown that this method is effective in accelerating the identification of basic feasible solutions and minimizing unnecessary iterations compared to the standard simplex method. Additionally, the two-phase method offers better numerical stability and high reliability in both industrial and educational applications. However, its effectiveness largely depends on the understanding of the algorithm and the ability to design an appropriate mathematical model. The results of this study are expected to contribute theoretically to the development of efficient solution techniques for linear optimization problems.

Abstract

Efficient resource allocation is a major challenge in various sectors, especially when faced with limitations in quantity, time, and cost. This study aims to examine the application of linear programming as an optimization method in solving assignment problems, where a number of resources must be optimally allocated to a number of specific tasks. Through a literature study approach, this study examines various relevant previous study results, especially in the Indonesian context. The results of the study indicate that linear programming is able to improve operational efficiency, reduce costs, and produce a more balanced task distribution. However, this model has limitations in dealing with non-linear conditions and data uncertainty, so integration with other methods such as fuzzy logic or genetic algorithms is needed. This study is expected to broaden the understanding of the benefits of linear programming and encourage its wider application in quantitative-based decision making.

Abstract

Scheduling and resource allocation are two crucial aspects in various fields, including manufacturing, transportation, education, and information systems. The complexity of decision making is often increased by integer constraints, such as the number of workers, machines, or indivisible working hours. Therefore, the Integer Linear Programming (ILP) approach is one of the methods widely used in solving optimization problems involving discrete variables. This literature study aims to review previous studies that apply ILP in the context of scheduling and resource allocation optimization. This study reviews model approaches, solution techniques such as the branch and bound method and cutting plane, and their implementation in various real cases. The results of the study show that ILP is able to provide optimal or near-optimal solutions in scenarios with complex constraints and integer variables. This study also identifies challenges in implementing ILP models, such as the scale of the problem and high computational requirements, as well as opportunities for further research that includes hybridizing the ILP method with a heuristic approach. Thus, ILP remains a very relevant and effective tool in supporting optimization-based decision making in various sectors.

Abstract

Learning evaluation plays a central role in ensuring the success of the educational process, especially in mathematics learning at Vocational High Schools (SMK) that require integration between theory and practice. This study aims to comprehensively analyze the implementation of formative and summative evaluations at SMK N 6 Padang. Using a descriptive qualitative approach, data was obtained through observations, in-depth interviews, and document analysis. The results show that formative evaluations are carried out systematically through essay tests, contextual quizzes, discussions, and observations of student participation. This evaluation can monitor learning progress, encourage active engagement, and strengthen students' conceptual understanding. Meanwhile, summative evaluations are consistently applied using multiple-choice questions that encompass low-order thinking skills (LOTS) to high-order thinking skills (HOTS). in line with the learning objectives and curriculum. Both forms of evaluation have proven to be very effective, based on teacher observations and feedback. Although not all aspects were followed up explicitly, the assessment mechanisms applied reflect the principles of modern evaluation that are adaptive, fair, and competency-based. It can thus be concluded that the evaluation is running very effectively at 88.88%, and the evaluation implementation at SMK N 6 Padang not only succeeded in measuring student achievement but also became an instrument to strengthen the quality of learning relevant to the demands of industry and the developments in 21st-century education.
