Ethnomathematics is one of the approaches that integrates local wisdom with mathematics learning. This study aims to develop PBL-based LKPD with ethnomathematics nuances at the Maimun Palace. This research method is research and development (Research and Development). The development model used as the basis for this study is the ADDIE development model (Analysis, Design, Development, Implementation and Evaluation). The results of the study showed that the LKPD developed was included in the valid category, for the average overall result of the LKPD validation assessment from the three validators was 4.35. In the implementation, the response of students to the LKPD with an average score of 4.48 was categorized as very good and met the practicality of the LKPD, so it did not need to be revised again. The PBL-based LKPD with ethnomathematics nuances produced, along with its supporting instruments, have met the criteria of validity, practicality, and effectiveness.

In everyday life, decision making is an unavoidable activity, both in personal, organizational and societal contexts. 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. Social, economic opportunities, capital, and market conditions play a significant role in providing resources and external incentives that support career decision making.

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.
