Abstract


Coastal waste pollution is an environmental problem associated with various human activities, including tourism and coastal settlements. This study aimed to analyze the distribution and compare the composition of coastal waste at two sites along Kemantren Beach, Paciran, Lamongan, characterized by different anthropogenic activity patterns. This observational study employed a field survey method using line transects approximately 200 m in length at each site. All macro-waste items were classified by type and analyzed descriptively and comparatively using the Chi-square test (α = 0.05). The results showed a total of 1,207 waste items, of which more than 87% consisted of single-use plastic waste based on the waste classification used in this study. The most dominant types of single-use plastic waste were plastic packaging/bags (52.11%), followed by plastic cups (15.08%) and straws (14.17%). The Chi-square test indicated a highly significant difference in waste composition between the two sites (χ² = 156.46; p < 0.001). This difference indicates variations in waste composition patterns between sites with different anthropogenic activity characteristics, although the intensity of anthropogenic activities was not directly measured in this study. These findings highlight the importance of coastal waste management strategies that consider the characteristics of each site, alongside efforts to reduce waste at its source.
