<![CDATA[This research aims to analyze in depth the mathematical literacy abilities possessed by students at SMP Negeri 11 Sungai Ambawang which are reviewed based on the initial abilities possessed by students with three categories of initial abilities, namely high, medium and low levels. This research is a descriptive qualitative research method in the form of a case study. In this research, the case that will be studied is how mathematical literacy skills are in solving HOTS-based algebra problems. Data collection tools in this research are tests and interview instruments. The subjects of this research were 24 students in class VIII A of SMPN 11 Sungai Ambawang. In this research, it was concluded that students with a high level of initial ability were able to fulfill three indicators of mathematical literacy, namely understanding and formulating, using and applying, and interpreting, while students with a medium level of initial ability were only able to fulfill two indicators, namely understanding and formulating, using and apply but cannot interpret. Meanwhile, students with low initial abilities are unable to meet the three indicators.]]>

<![CDATA[This research aims to determine whether there are differences in mathematical problem solving abilities through the contextual learning model assisted by Quizizz in terms of visual spatial intelligence. This research is a quantitative research type of True Experimental Design. The research subjects were class VIII students at SMPN 17 Pontianak with a total of 60 students. The samples in this study were class VIII B as an experimental class using the contextual learning model assisted by Quizzizz and class VIII A as a control class using a conventional learning model. Data was obtained from the mathematical problem-solving ability test given to students. The data analysis technique used a two-way anava test and an advanced test using a double comparison test with the Sheffe method. Based on the results of the analysis and discussion of the research data, the results were obtained that the ability to solve mathematical problems using the quizizz-assisted contextual learning model is better than the ability to solve mathematical problems using the conventional learning model. There is an interaction between the quizizz-assisted contextual learning model and students' spatial visual intelligence on mathematical problem solving]]>

<![CDATA[Combinatorial optimization is a fundamental area in operations research and computer science, focusing on identifying optimal solutions from a finite set of possibilities. This study explores the integration of branch and bound methods with heuristic algorithms to address optimization problems in graph theory and discrete mathematics. Python was employed for algorithm implementation due to its flexibility and comprehensive computational libraries, enabling efficient data analysis and visualization. Several benchmark problems were examined, including the Traveling Salesman Problem (TSP), Minimum Spanning Tree (MST), and Graph Coloring. Simulations were conducted using datasets of varying sizes (small, medium, and large) to evaluate performance across different scales. The results demonstrate that the hybrid approach achieves a balance between solution quality and computational efficiency, outperforming brute-force methods in terms of speed while maintaining near-optimal accuracy. Tabulated results and graphical comparisons highlight the reduction in computation time and improved scalability of the proposed method. The findings suggest that combining systematic search strategies with heuristics offers a practical and effective framework for solving complex combinatorial optimization problems. Recommendations for future research include testing scalability with larger datasets, incorporating advanced metaheuristics, and applying the approach to real-world domains such as logistics and network design.]]>

<![CDATA[This study aims to compare the effectiveness of Game Based Learning (GBL) model assisted by wordwall with Problem Based Learning (PBL) on the mathematical problem-solving ability of class X students of SMA Negeri 1 Sungai Raya on the material of arithmetic sequences and series. The research method used Quasi Experimental Design with Nonequivalent Control Group Design. The sample was selected through purposive sampling, namely class X8 as the experimental class (31 students) who implemented GBL assisted by wordwall and class X6 as the control class (31 students) who implemented PBL. The research instrument used was a problem-solving ability test on the material of arithmetic sequences and series. Data were analyzed using paired sample t-test and independent t-test. The results showed that both models were able to improve students' mathematical problem-solving ability. The experimental class increased from 58.60 to 84.94 with N-Gain 0.64 (medium category), while the control class increased from 59.03 to 71.93 with N-Gain 0.31 (medium category). The independent t-test shows tcount = 4.3255 > ttable = 2.0003 (α = 5%), so the mathematical problem-solving ability of students taught using GBL assisted by wordwall is better than PBL. Digital games create interesting and challenging learning, encouraging active student involvement.]]>
