To write linguistic markers cohesively writers must use cohesion to join ideas between sentences to create texture. However, unrelated sentences will be difficult for the readers to understand. Therefore, the purpose of this research study is intended to analyze cohesive device used and to identify cohesive errors that the students had in their essays. This study was descriptive –qualitative research method. The sources of the data are the linguistic markers that link a text cohesive, including cohesive errors. There are 29 students’ essays collected to be analyzed. The results of the research study revealed that there were four types of cohesive devices used: Reference (45,38%); Lexical Cohesion 39,33%, Conjunction 14,90%, and Substitution 0,37%. Dealing with the cohesive errors, the most frequency of errors was reference with the percentage 55, 85%, conjunction 16, 48%, lexical cohesion 2, 76%.
