Abstrak - Grammatical cohesive devices are significant components in writing that contribute to the texts organization and comprehensiveness. Therefore, it is necessary for students to comprehend these rules. This study was carried out to determine the varieties of grammatical cohesion that students often use and coherence in the background of under graduate thesis. This qualitative research applies a discourse analysis as the research method. The objects of this research are 21 research backgrounds in thesis produced by undergraduate students of the English Language Education Study program in 2020/2021 academic years that taken from etheses.iainkediri.ac.id. In analyzing the data, the researcher used Halliday and Hasan theory about Cohesive devices especially the one which is focused on grammatical cohesive device.The findings demonstrated that the implementation of grammatical cohesion devices in their writing quite varied. The conjunction device is the most commonly used type by students, accounting for 83% of all devices used; reference devices account for 16% of all devices used. As for other devices that are rarely used and not used at all are substitution devices and ellipsis devices with a total of 1% for substitution devices and 0% for ellipsis devices. In addition, there are some mistakes in using the grammatical cohesion devices. In the use of grammatical cohesion devices there are 15% use of inappropriate references and 8% use of inappropriate conjunctions. The findings show that students are more accustomed to using references and conjunctions than substitutions and ellipsis. From the results of the study, it can be noticed that the students able to develop texts is good, this can be seen from the results of observations that show the least errors in the use of grammatical cohesive devices. In addition, their writings has connectivity in the text so that it can be easily understood by readers. From observations, they have used almost all grammatical cohesion devices except the ellipsis devices; this may be due to a lack of understanding about this device.
