This study aims to analyze errors in the use of Enhanced Spelling (EYD) in writing explanatory texts by grade 6 elementary school (SD) students. Explanatory text is an important type of text in learning Indonesian, but students often make mistakes in using EYD when writing this text. This research uses descriptive qualitative methods with content analysis and interview techniques. Data were obtained from explanatory texts written by 6th grade elementary school students and the results of interviews with the principal, homeroom teacher, and 15 students. The research results show that students still make many mistakes in using EYD, especially in the use of capital letters, punctuation and writing words. This error is caused by students' lack of understanding about EYD, lack of practice in writing explanatory texts, lack of teacher attention to EYD teaching, and lack of support from the home environment. This research recommends that teachers pay more attention to EYD teaching, provide regular explanatory text writing practice to students, increase collaboration with parents, and create a learning environment that is conducive to the development of students' writing skills.
