Optimization of Essential Skills in 21st In Students Through STEM Integrated Research Based Learning

: The problem of the research is the low basic skills possessed by students, so that students have the potential to find it difficult to find work in accordance with their field. With the enactment of economic changes globally, the world of work, both nationally and internationally, provides requirements for prospective workers who will enter the workforce concerned to have essential skills in the 21st century. STEM implementation in research based learning aims to instill, grow and develop the basic skills needed in essential skills in the 21st century. This research will be conducted using experimental research methods with the data analysis technique used is the analysis of covariance (anacova) 1 way with 2 covariances. The sample of this research is 124 students majoring in mechanical engineering, Faculty of Engineering, State University of Malang. The result of the study is that there is a significant difference between the STEM integrated research based learning group and the conventional group controlled by the variable learning skills and the ability to innovate.
