This research presents the effects of reputation systems on trust, trust in buying interest, and reputation systems on Bukalapak customers' buying interests. A total of 120 respondents participated and the data were analyzed using structural equation modeling with Amos 20 software. The results show that the reputation system has a higher direct impact compared to the impacts mediated by trust. Therefore, in an effort to increase the buying interest, the sellers should increase their reputation in the reputation system represented in the list of feedback, review, and the badge level in Bukalapak. To marketplace providers, in this case, Bukalapak, there is still a need to increase the customers' trust. Although it is significant, however, it has low impacts both directly and indirectly.
