Abstract

Uma Lengge is a traditional building located in the Wawo Bima district. Uma Lengge illustrates the robustness of traditional buildings that have beautiful and neat images by reflecting geometric shapes. The purpose of this research is to describe the traditional building of Uma Lengge as a source of implementation of ethnomathematics-based mathematics learning. The method used in this research is exploratory-descriptive and involves traditional building craftsmen like Uma Lengge as the main data source. Data analysis techniques used include data reduction, data presentation, and verification. The results showed that there were mathematical concepts in the form of measurement and the application of traditional arithmetic for the Bima community. In addition, there are geometrical concepts of plane and space, as well as mathematical concepts in the process of making Uma Lengge. This proves that Uma Lengge can be a source of applying ethnomathematics-based mathematics learning because good mathematics learning should have a relationship with the realities of people's lives, one of which is culture.

Abstract

The development of digitalization technology in the world of education emphasizes the need for progressive learning innovation, not only focusing on procedural memorization, but it is important to integrate geometric concepts with cultural values ​​and STEM approaches. As for alternatives that answer these needs, the purpose of this study is to develop an Ethno-STEM based e-module that focuses on the Uma Lengge building as a geometry learning context to improve the mathematical representation abilities of junior high school students. In the development of this e-module, the ADDIE development model is used, which is Analysis, Design, Development, Implementation, Evaluation. In the data collection process by conducting observations, as well as using tests, andquestionnaires. The feasibility test obtained an e-module with a valid category in the material and design aspects, in addition, responses by students regarding the practicality of the module are in the practical category for use in learning, while the effectiveness test of the e-module showed an increase in students' representation abilities in the post-test results with a moderate to high increase, which indicates a significant difference from the pre-test results. So the Ethno-STEM based e-module focusing on the Uma Lengge building with the context of geometry material is effectively used to improve the mathematical representation abilities of junior high school students.
