Effectiveness of the Nutmeg Flower Dryer Monitoring Module in Improving Students’ Digital Literacy Comprehension

The rapid advancement of technology has emphasized the need for digital literacy among vocational students, particularly in technology-intensive sectors. However, learning modules that effectively integrate vocational content with digital literacy skills remain limited. This study aimed to evaluate the effectiveness of a Nutmeg Flower Dryer Monitoring Module in improving students' digital literacy comprehension within a vocational education context. A quasi-experimental design with pretest-posttest control groups was employed, involving 60 eleventh-grade vocational students in electronics engineering programs. The experimental group (n=30) received instruction using the IoT-based monitoring module, while the control group (n=30) engaged in conventional textbook-based learning. Data were collected using a 40-item digital literacy test and a 20-item student response questionnaire, then analyzed through N-gain calculation and independent samples t-tests. Results revealed a significant improvement in the experimental group's digital literacy, with an overall N-gain of 0.71, categorized as highly effective. The greatest gains were observed in communication literacy, indicating enhanced competencies in interpreting and interacting with real-time digital systems. Students also reported high satisfaction and perceived relevance to vocational tasks. The findings confirm that contextualized, hands-on IoT modules effectively bridge theoretical knowledge and practical digital skills. Future work should explore multi-site implementation, longitudinal retention, and adaptation to other vocational domains to further optimize digital literacy outcomes.
