This research is qualitative descriptive research. The subject of this research is the elementary school teacher of SDIT Ulil Albab Kebumen. Data collection techniques were conducted with document analysis, interviews, and observations. The data analysis technique used is the interactive analysis by Miles and Huberman that begins with data collection, data reduction, data display, and conclusion drawing. The results showed that online learning was a challenge for elementary school teachers in the Covid-19 pandemic. Online learning has been implemented by utilizing online learning platforms such as Quizizz, TVRI broadcast, YouTube, Whatsapp Group, etc. However, SDIT Ulil Albab teachers are not yet fully prepared in implementing online learning so that online learning has not been implemented optimally. There are several obstacles in the implementation of online like limited internet access, some teachers have not been accustomed to facilitating the online learning of students, declining student motivation, and elementary school students who still need mentoring in using technology learning. The solution to overcome these obstacles is to involve all parties from teachers, schools, and parents to create ideal online learning. Ideal online learning can advance the quality of education in Indonesia in facing the 5.0 era.
