Abstract

Food waste contributes significantly to global greenhouse gas (GHG) emissions and reflects low sustainability awareness, particularly in developing countries such as Indonesia. This study aimed to assess the level of sustainability literacy, comprising knowledge, skills, and values, among vocational high school students in Bogor City within the context of food waste. Using a descriptive quantitative method with 125 respondents, data were collected through a 21-item questionnaire and were analyzed using descriptive statistics. The findings show that while students demonstrated good sustainability skills (76.95%) and values (73.63%), their sustainability knowledge was only fair (57.81%), indicating a cognitive-behavioral gap. Spearman's correlation analysis revealed no significant relationship between sustainability knowledge and skills (ρ = 0.109, p = 0.226), reinforcing the need for holistic and integrative learning interventions. These results underscore the importance of developing interactive, value-driven educational media, such as e-books, to enhance students' environmental literacy and foster sustainable behavior. This preliminary study serves as a foundation for designing contextually relevant educational strategies to support food waste reduction and sustainability education in Indonesia.

Abstract

Food waste poses a serious environmental challenge that requires not only conceptual awareness but also practical sustainability competencies. This study aims to profile vocational high school students sustainability literacy in the skills domain of food waste education as a preliminary step toward developing interactive learning media. A total of 36 Grade X students in Bogor participated in a field trial using a prototype e-book entitled Awas Food Waste. Students were assigned to solve a contextual case, design digital posters, and present their solutions in class. Poster texts (365 words) were analyzed through word-frequency techniques, while oral presentations were assessed using a rubric adapted from Murray and Cotgrave. Results showed that frequently used terms indicated both problem recognition (e.g., sisamakanan [food leftovers], food waste, sampah [waste]) and proposed solutions (e.g., kompos [compost], maggot, organik [organic]). The presentation scores averaged 3.53 (median = 3; mode = 3), categorized as sufficientgood, with 22.2% of students achieving a very good level. These findings reveal that students are able to identify and communicate practical strategies to reduce food waste, although the depth and innovation of solutions remain limited. The study highlights a gap between awareness and applied action, underscoring the importance of scaffolding through interactive e-books and other digital media. This preliminary evidence serves as a baseline for designing pedagogically grounded interventions to strengthen vocational students sustainability skills and foster responsible environmental behavior
