Algebraic thinking plays an essential role in increasing mathematics problem-solving abilities. In this study, the pre-service mathematics teacher’s (PMTs) ability of algebraic thinking is explored based on a systematic-intuitive cognitive style. This study aims to reveal students' algebraic thinking abilities regarding systematic-intuitive cognitive style. Three components of algebraic thinking were analyzed: arithmetic generalization, functional thinking, and generalization and justification. The research approach is qualitative with a case study method. The subjects were 31 PMTs at one of the private universities in Surakarta District, Central Java, Indonesia. Data collection methods were algebraic thinking tests, the Cognitive Style Inventory (CSI) questionnaires, and interview protocol. Four subjects, two PMTs for each cognitive style category were interviewed to reveal their algebraic thinking abilities. The results showed that all subjects were able to solve the functional thinking problem correctly. However, for the generalization arithmetics and justification problems, the PMTs abilities are varied. In addition, the finding also showed the different strategies of systematic and intuitive subjects in solving the problems related to algebraic thinking components. PMTs with a systematic cognitive style solve problems systematically and represent the pattern verbally in the form of a table or word, whereas the PMTs with an intuitive cognitive style solve the problem briefly and visually using pictures pattern. In conclusion, there is a relationship between algebraic thinking ability and cognitive style.

AJW is a consumer goods distribution company for Indofood products and non-Indofood products. PT. AJW moves throughout Karo district. The number of tourist attractions in Karo makes the demand for goods higher such as Pop noodles, Indomie, chitato and others. Thus, having an impact on the distribution of goods Based on the author's observations at PT. AJW Kabanjahe has no standard provisions in determining the route, the delivery of goods is still carried out based on requests from consumers so that it ignores the distance traveled and time. A way that can solve this distribution problem is the Capacitated Vehicle Routing Problem (CVRP). CVRP is a problem in determining the optimal route by looking at the problem that each vehicle has a capacity limit. To solve CVRP problems, a good heuristic algorithm is used is the sweep algorithm and local search route improvement. This study uses the sweep algorithm to solve the CVRP problem, and the routes obtained by the sweep algorithm will be improved with local search. The sweep algorithm is a simple method of calculation, even for calculating large problems. The sweep algorithm will be combined with local search. Local search is an algorithm used to get shorter routes. The combination of the two algorithms is perfect for solving CVRP problems. After research, a distance of 39.96 km was obtained compared to the company's route of 103.5 km. So the percentage of mileage savings is 61.39%. This shows that sweep algorithms can minimize distance while saving company expenses

This study aims to address the lack of interactive learning media specifically designed to enhance students' critical mathematical thinking skills in the topic of function composition. Based on previous research highlighting the potential of viral media in mathematics learning, this study develops and tests an innovative learning medium called GABUT. This medium integrates game elements and interactive learning using QR codes and various levels of problem difficulty. The methodology employed is Research and Development (R&D) with the 4D development model: Define, Design, Develop, and Disseminate. In the Define stage, needs analysis was conducted through interviews and questionnaires. The Design stage involved the initial prototype design of the GABUT media. During the Develop stage, the prototype was tested and evaluated through pre-tests, post-tests, and statistical t-test analysis. The Disseminate stage involved implementing the media in several schools over 12 weeks. The results indicate that GABUT media effectively enhances students' critical mathematical thinking skills, with an average test score improvement of 25% (standard deviation = 5.6, p-value < 0.05). Additionally, 85% of students reported feeling more motivated and engaged in learning mathematics after using this media. Challenges encountered included students' initial adaptation to the new media and issues with "zonk" questions. Improvements were made through initial orientation sessions and revisions to the "zonk" questions. This study makes a significant contribution to mathematics education by providing an innovative and effective learning medium that not only improves students' conceptual understanding of mathematics but also motivates them and increases their participation in the learning process.
