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.

Engineering is a science that studies the skills of creating tools and processing methods to perform various human tasks. Education is the conscious effort to prepare students for future tasks through teaching, learning and/or training. Character is a set of qualities that are always admired as a sign of a person's goodness, virtue and moral maturity. The purpose of this research is to conduct a literature review, ie. to find out the importance of technology in the development of a student's character. The method used is the Systematic Literature Review (SLR) strategy. SLR is a research method that aims to systematically identify, examine and interpret information obtained from journals at certain stages. The research results show that the integration of technology into education not only supports the learning process, but also plays an important role in the development of the student's character. Technology-based education encourages students to think critically, collaborate and adapt to the rapid changes of the digital age. Therefore, technology is an important tool to develop students who are academically intelligent in accordance with the values of Pancasila, but also with strong character and noble morals.
