The Covid-19 pandemic (corona virus disease-2019) is an acute problem that has a multidimensional impact on all sectors of life, one of which is the education sector. Based on the Decree of the Ministry of Education and Culture (Kemdikbud) through Circular Number 4 of 2020, it decided to postpone all school activities and switch to online learning or distance learning (PJJ). Changes in the learning scheme are considered to have a negative impact on the learning process, especially student learning outcomes. Vocational High School (SMK) students also experience this problem more, which in their learning process prioritizes practice in mastering vocational skills and abilities. As a result, many students experience a decrease in the value of learning outcomes and mastery of the abilities they learn due to minimal or even no direct practical learning experienced by SMK students. Therefore, a solution is needed to support the learning process for vocational students during the Covid-19 pandemic, one of which is through designing a vocational assistance management system (SIMAK SMK) based on an android application. In the development process, research procedures were carried out through literature studies and field studies, then producing media by making flowcharts, then making media according to the design that had been made. The final stage is media evaluation which is validated by educational evaluation experts and educational technology validation experts to see the feasibility of the media and make reports.
