Abstract

This study aimed to analyze the relationship between environmental pollution knowledge and pro-environmental behavior and to determine the differences in both variables based on students' grade levels. This research employed a quantitative approach with a correlational design. The study was conducted at SMA Negeri 2 Muaro Jambi with a population of 900 students from grades X, XI, and XII. A total of 90 students were selected using the Slovin formula and proportionate stratified random sampling, consisting of 32 grade X students, 29 grade XI students, and 29 grade XII students. Data were collected using a 20-item multiple-choice test to measure environmental pollution knowledge and a 20-item Likert-scale questionnaire to measure pro-environmental behavior. Data were analyzed using normality, linearity, homogeneity, Pearson Product-Moment correlation, and One-Way ANOVA tests. The results showed a positive and significant relationship between environmental pollution knowledge and pro-environmental behavior across all grade levels. The correlation coefficients were 0.908 for grade X, 0.729 for grade XI, and 0.883 for grade XII, with a significance value of 0.000 < 0.05. The One-Way ANOVA results indicated no significant differences in environmental pollution knowledge or pro-environmental behavior based on grade level. Therefore, environmental pollution knowledge was positively associated with students' pro-environmental behavior, while grade level did not produce significant differences in either variable.
