This study aims to evaluate a Food Microbiology handout by analyzing its validity, practicality, and effectiveness for undergraduate Biology students at Malang State University. The research method used is Research and Development (R&D) with the ADDIE developmental model. The subjects of this study were undergraduate students in the Biology Education program. Research instruments consist of: expert validation sheets, practicality questionnaires, and pretest-posttest questions. Validation was done by a material expert, a learning practitioner, and a learning media expert. The results indicated that the handout was valid with an average percentage score of 100%. The practicality test results showed that students think the handout is practical, easy to understand, and supports the learning process, with an average score of 85%. The pretest and posttest analysis proved an improvement in learning outcomes, with a moderate increase according to N-Gain scores: 41% for critical thinking skills and 38% for cognitive knowledge. Based on these results, the handout is worthy of being used as teaching material in Food Microbiology courses.
