Abstract
Research Based Learning (RBL) is a learning method that uses contextual learning, authentic learning, problem solving, cooperative learning, hands on and minds on learning and inquiry learning. The STEM approach in learning is expected to provide meaning to students through the systematic integration of research-based knowledge, concepts and skills. STEM design begin with the identification of social problems. The social issue of typhoid fever cases caused by Salmonella typhi bacteria with a high mortality rate in the world is a public health problem. The existence of Pheretima javanica which is abundant in the environment can be utilized by conducting antibacterial activity testing and analysis of bioactive compounds by students on the form of the extract. This research is a development research carried out with the aim of developing a product and also a qualitative descriptive research which serves to provide an overview of the object. The steps in carrying out these tests were identified as part of learning that hone creative thinking skills. Learning outcomes contribute to the effort to find alternative drugs that are effective and do not cause resistance. In addition, students also produce scientific articles as learning products. This paper has implications for STEM integrated research-based learning.
