<p>Adolescents’ sustainability consciousness in the SDG2 context remains underexamined in Indonesia. This study addressed three questions: whether junior high school students’ sustainability consciousness differs by demographic factors, how strongly knowingness, attitude, and behavior are related, and whether the tripartite structure (knowingness–attitude–behavior) is supported in the SDG2 context. A questionnaire was administered to 773 students (Grades 7–9) from urban and rural schools. Demographic differences were examined using Kruskal–Wallis and Mann–Whitney U tests, followed by Spearman’s correlations and PLS-SEM in SmartPLS. Grade 9 students scored higher than Grade 7 students (p = 0.009), females higher than males (<i>p</i> &lt; 0.001), and urban students higher than rural students (<i>p</i> &lt; 0.001), with small-to-moderate effects (d ≈ 0.25–0.40). Knowingness was moderately associated with attitude (ρ = 0.644) and positively associated with behavior (ρ = 0.467), whereas the strongest association was found between attitude and behavior (ρ = 0.682). The measurement assessment supported the tripartite conceptualization of sustainability consciousness for SDG2. The study’s novelty lies in situating sustainability consciousness within an SDG2-specific framework, testing its tripartite structure in Indonesian junior high school students, and demonstrating that attitude is more strongly associated with behavior than knowingness, suggesting that knowing alone may be insufficient to drive behavior change. To advance SDG2, curricula should address food insecurity, malnutrition, and sustainable agriculture through learning designs that build attitudes alongside knowledge and create feasible opportunities for action.</p>

摘要

Adolescents’ sustainability consciousness in the SDG2 context remains underexamined in Indonesia. This study addressed three questions: whether junior high school students’ sustainability consciousness differs by demographic factors, how strongly knowingness, attitude, and behavior are related, and whether the tripartite structure (knowingness–attitude–behavior) is supported in the SDG2 context. A questionnaire was administered to 773 students (Grades 7–9) from urban and rural schools. Demographic differences were examined using Kruskal–Wallis and Mann–Whitney U tests, followed by Spearman’s correlations and PLS-SEM in SmartPLS. Grade 9 students scored higher than Grade 7 students (p = 0.009), females higher than males (p < 0.001), and urban students higher than rural students (p < 0.001), with small-to-moderate effects (d ≈ 0.25–0.40). Knowingness was moderately associated with attitude (ρ = 0.644) and positively associated with behavior (ρ = 0.467), whereas the strongest association was found between attitude and behavior (ρ = 0.682). The measurement assessment supported the tripartite conceptualization of sustainability consciousness for SDG2. The study’s novelty lies in situating sustainability consciousness within an SDG2-specific framework, testing its tripartite structure in Indonesian junior high school students, and demonstrating that attitude is more strongly associated with behavior than knowingness, suggesting that knowing alone may be insufficient to drive behavior change. To advance SDG2, curricula should address food insecurity, malnutrition, and sustainable agriculture through learning designs that build attitudes alongside knowledge and create feasible opportunities for action.
