Instructional media play a vital role in improving the quality of a learning process, especially in helping the students to learn. Local-potential instructional media are expected to be able to motivate university students to learn preservation methods of invertebrates. However, the quality of the media should be number one priority. This study aimed to examine the quality of instructional media developed in the form of fluid-preserved or wet specimens which were stored in alcohol and formalin. This study used a descriptive approach to data analysis. A comparative analysis of experimental results was performed in this study. The media were evaluated based on the following aspects: compliance with the curriculum standard, quality of the materials, language use, presentation, intelligibility, and benefits of the media. The data were collected using a documentation method and analyzed using a qualitative data analysis technique. The result of the analysis showed that the media complied with the Indonesian National Qualification Framework (KKNI) curriculum standard competencies. In addition, the media also obtained high scores in the quality of the materials, language use, presentation, intelligibility, and benefits (95.78%, 98%, 96.20%, 95.40%, and 97.60%, respectively). Overall, the invertebrate preservation media analyzed in this study have been qualified as proper media to support learning in the classroom.
