Each individual or group is often faced with various alternative choices, where each choice has certain consequences. In your career, decision making is very important. In making a decision there are definitely factors that influence it. In this research, the author used the Systematic Literature Review (SLR) method This research uses a Systematic Literature Review (SLR) approach with data sources originating from previous journal literature.  Data collection was carried out by documenting all articles and journals that were relevant to this research. From 20 similar articles, researchers took 10 articles to analyze and summarize. The results of this research show that the factors that influence career decision making are internal factors which include self-efficacy, motivation, interests, skills and personal perceptions, which are the psychological and emotional basis for individuals in determining their career direction, as well as external factors such as family support, the environment.

This study examines ethnomathematics in traditional tools of the Malay ethnic group at the North Sumatra Provincial Museum, encompassing ceremonial and livelihood tools. The research employs a qualitative approach using ethnographic methods to explore the mathematical concepts embedded in these objects. Ceremonial tools such as bentan, tiered trays, incense burners, and glass holders were analyzed based on geometric concepts such as circles, cylinders, ratios, and sequences, while livelihood tools such as goat hoofs, horns, sickle, and one-sided fish traps represent spatial geometry, symmetry, and volume concepts. The findings reveal that these traditional objects not only serve practical purposes but also contain mathematical and philosophical values reflecting Malay culture. These tools can be utilized as context-based mathematics learning media, helping students understand mathematics through the lens of local culture. This study emphasizes the significant role of ethnomathematics in integrating education with cultural preservation while strengthening local identity in the era of globalization.

Real analysis is a course that requires formal proof of a formal definition. Almost all students have difficulty learning real analysis. These problems require the provision of learning models that can serve students who learn real analysis. The purpose of this study is to provide an overview or description of the Model to improve the quality of real analysis lectures. The method used in this study is Systematic Literature Review. The results of the study concluded that models to improve the quality of real analysis lectures are very diverse. Learning models such as the use of Flow Proof and Extended Triad Level ++ Learning Models, to the application of learning modules such as Project-Based Learning Modules can be effectively and efficiently used to improve the quality of real analysis lectures.
