Using Learning Management System (LMS) is ubiquitous in higher education now, but sometimes teachers do not understand its barriers before implementing it. This research aims to explore the obstacles to using LMS-Edmodo on EFL speaking tasks based on the students' perceptions. It involved ten business college students from a private university in Yogyakarta, Indonesia, and employed a qualitative descriptive approach that applied several instruments such as observation, documentation, and interview. The data were collected by a screen capture tool to find the students' tasks on Edmodo that contained barriers indications and collaborated with an interview before they were transcribed and coded by using three stages of qualitative analysis, which were data reduction, data display, and conclusion drawing and verification. Based on the students' perceptions, the barriers to using Edmodo on EFL speaking tasks are requiring high speed of Internet connection, needing other supports for technologically backward students, lack of virtual teachers support and needing f2f meeting. Therefore, providing speaking tasks as long as paying attention to the students' characteristics can use LMS-Edmodo.
