Abstract
This study aims to determine the benefits of the Mendeley application for students in
writing scientific papers for library and information science students using the ISO/IEC
9126-2 Usability measurement method based on the four characteristics as indicators,
namely Understandability, Learnability, Operability, and Attractiveness. This study used an
experimental method, namely pre-experimental designs. Pre-Experimental Designs This
research is a design that includes pre-test, treatment and post-test. The population in this
study were library and information science students class of 2020. The number of samples
in the study were 47 people. The sampling technique is basic accidental examining
(inadvertent inspecting), namely distributing questionnaires to respondents using Google
structure via the WhatsApp application. The results of the pre-test showed that the
understanding level of the Mendeley application reached 2.66%, the operability level of the
Mendeley application reached 2.15%, the learnability level of the Mendeley application
reached 1.51 %, and the attractiveness of Mendeley applications is 3.11%. The results of the
post test showed that the understanding level of the Mendeley application reached 7.11%,
the operability level of the Mendeley application reached 10.4%, the learnability level of the
Mendeley application reached 3.45 %, and the attractiveness of the Mendeley application is
7.55%. From the pre test results, the post test results increase in the utilization and
operation of the Mendeley application. Based on these results it is concluded that the
Mendeley application has been utilized by users properly.
