This study aims to describe the use of reference grammatical cohesion markers in the novel "Khotbah di Atas Bukit" (Sermon on the Hill) by Kuntowijoyo. The data used are sentences that have reference grammatical cohesion. The data collecting technique used involved conversation observation technique. A distributional method is used to analyse the data. The results of the study revealed that the reference grammatical cohesion markers consisted of 158 personal pronouns, 56 demonstrative pronouns, and 11 comparative pronouns. Most of the reference grammatical cohesion markers were personal pronouns. The results of the study can be implemented in Indonesian language learning in high school. Therefore, as a result, teachers should be able to create learning scenarios to be implemented in the classroom.
