The time-span of completing the minor thesis in Indonesian undergraduate programs has been one of the significant issues in higher education accreditation and quality insurance. Therefore, it is important to assess the possible determinants such as gender, research approach, and type of research, which might effect the students' completion period of minor thesis ("Skripsi"). This study used quantitative approach and involved 719 university students. The data was collected from the Faculty database from 2014 to 2017 and Mann Whitney U test and Crosstab analysis were applied to analyze the data. The result of this study showed that gender and research approach did not significantly contribute to the students' minor thesis completion period. Additionally, students who chose independent research, as their type of research, were able to finish their "Skripsi" faster than those who conducted joint research.
