This workshop has several main objectives, namely:

  1. Improving lecturers' understanding of the concept of instrument validity and reliability and the importance of both concepts in research.
  2. Training lecturers in conducting instrument validity and reliability tests using SPSS software.
  3. Facilitating lecturers in developing quality research instruments to support research activities at FMIPA UNUD.
  4. Supporting the improvement of research quality at FMIPA UNUD through the use of valid and reliable instruments.


Two speakers for this workshop came from the Mathematics Study Program, namely Dr. Made Ayu Dwi Octavanny, S.Si. and Anggun Yuliarum Qur'any, S.Si., M.Si., where they both gave an explanation of the concept of instrument validity and reliability. They explained that validity is related to the extent to which an instrument measures what should be measured, while reliability shows the consistency of measurement results. After the presentation, participants were trained to conduct validity and reliability tests using SPSS software. Participants showed high enthusiasm during the workshop, as seen from their activeness in the discussion. Ratna Sari Widiastuti, S.Si., M.Sc., as the moderator played an active role in guiding the discussion and answering various questions from participants.


By holding this workshop, it is expected to provide a significant contribution in improving the quality of the implementation of the tridharma of higher education at FMIPA UNUD.
