E-Learning has been massively used in higher education, one of which is in Universitas Indonesia. The e-learning system in Universitas Indonesia is called Student Centered E-Learning Environment Universitas Indonesia (SCELE UI). This research determines the effect of usability on the intention to use SCELE UI in a sustainable way. The Expectation Confirmation Model (ECM) is used as a basis of the research model. Perceived Usability, Learnability, Presentation, Navigation and Error variables are added to the model. The Partial Least Square is used to analyze and test the model. Of the 12 proposed hypotheses, 10 hypotheses were accepted and 2 hypotheses were rejected. This research gives theoretical and practical contributions. On the theoretical side, this research successfully proposes and examines the integration of usability and ECM in the context of sustain e-learning usage intention. This research reveals the indirect effect of Perceived Usability on continued usage intention of the e-learning system. On the practical side, this research also provides insights for developers and universities that can help them to effectively foster the improvement of their system that can ensure sustained usage by their students.

电子学习已被大量用于高等教育，其中之一是在印度尼西亚大学。Universitas Indonesia 的电子学习系统被称为以学生为中心的电子学习环境 Universitas Indonesia (SCELE UI)。这项研究确定了可用性对以可持续方式使用 SCELE UI 的意图的影响。预期确认模型 (ECM) 用作研究模型的基础。感知可用性、可学习性、演示、导航和错误变量被添加到模型中。偏最小二乘用于分析和测试模型。在提出的 12 个假设中，有 10 个假设被接受，2 个假设被拒绝。本研究做出了理论和实践贡献。在理论方面，本研究成功地提出并检验了在维持电子学习使用意图的背景下可用性和 ECM 的整合。本研究揭示了感知可用性对电子学习系统持续使用意愿的间接影响。在实践方面，这项研究还为开发人员和大学提供了见解，可以帮助他们有效地促进系统的改进，以确保学生的持续使用。
