In order to better understand the pros and cons of implementing an online curriculum at SMK Negeri 1 Kotamobagu, this study aims to explain the efficacy of online learning techniques for teaching Indonesian language courses. Moreover, explain what has to be changed to make e-learning more efficient. This study employs a descriptive qualitative methodology, which tries to zero in on practical issues by first collecting, describing, and then analyzing obtained data. The Indonesian Language Instructor of SMK Negeri 1 Kotamobagu provided the information used in this analysis. According to the findings, majority of the people who provided explanations for the study concluded that online schooling was less successful. It is true that traditional classroom instruction is superior than online learning due to factors such as students' increased access to course materials in a variety of visual formats (including learning films, soft copies, and photographs) (taking notes). While the benefits of online education are undeniable, there are some drawbacks. Because online learning occurs in the home, there are certain things that can be adjusted to make it more successful. First, students need to be better prepared to embrace the learning process.
