<![CDATA[Science, Technology, Engineering and Mathematics (STEM) education is seen as a way to create quality and competitive human resources entering the Industrial Revolution 4.0 era of the 21st century. The Ministry of Education and Culture of the Republic of Indonesia initiated its own STEM education trend since 2018. However, the STEM education movement in Indonesia is still rare, so STEM education needs to be developed. This service activity is based on the partner's problem, namely that the science teachers at this vocational school do not really know about STEM education, and so far there has never been anything held regarding the introduction of STEM education and how to integrate STEM in lessons. This service activity is carried out through the introduction of STEM education and integrating STEM education in science lessons to improve teacher professionalism. As an evaluation material for the success of implementing this service, participants were given a pretest and post-test regarding the participants' understanding and insight regarding STEM and its integration in learning.
