The need for online learning media is increasing during the pandemic to ensure the teaching and learning process continues to run well in vocational high schools. The variety of learning media used for a subject causes inefficient learning activity. Therefore, this research proposes a Learning Management System design using the Software Requirement Specification to meet all user needs in system development. The use of the Software Requirement Specification is necessary because of the complexity of the functions possessed by the developed Learning Management System. The Software Requirement Specification used in this development complies with IEEE standards. As a result, the LMS design created using SRS provides a complete picture of the required components and constraints according to user needs. The development of this LMS can facilitate the online teaching and learning process where students and teachers can carry out activities according to the conditions specified.
