Abstract

Mikroplastik kini mengancam kualitas air, pangan, dan kesehatan masyarakat, diperburuk oleh tingginya penggunaan plastik sekali pakai di rumah tangga dan lemahnya sistem pemilahan sampah. Urgensinya meningkat karena akumulasi mikroplastik berdampak langsung pada risiko penyakit dan keberlanjutan ekosistem. Indonesia membutuhkan penguatan regulasi mikroplastik, insentif ekonomi untuk mengurangi plastik sekali pakai, serta standar teknis bagi produk biodegradable. Pemerintah daerah perlu memastikan pemilahan dari hulu ke hilir, sementara rumah tangga harus difasilitasi melalui akses alternatif ramah lingkungan dan program perubahan perilaku. Intervensi lintas sektor menjadi kunci untuk menekan risiko dan menjaga kesehatan serta lingkungan berkelanjutan.

Abstract

Introduction: Microplastic pollution has emerged as an increasingly urgent environmental problem, highlighting the need to better understand the psychological and social factors that encourage households to engage in pro-environmental behavior. Grounded in the Theory of Planned Behavior, this study examines how microplastic knowledge, risk perception, attitudes, subjective norms, and perceived behavioral control shape pro-environmental intentions among urban and rural housewives, extending TPB by integrating knowledge and risk perception. Methods: A quantitative research design was applied by distributing structured questionnaires to 600 respondents, comprising 300 urban and 300 rural housewives in Bogor City and Bogor Regency. Data analysis involved independent t-tests to identify differences between the two groups, and Structural Equation Modeling (SEM) to examine the causal relationships among the studied variables. Results: The results show significant urban–rural differences in microplastic knowledge, risk perception, subjective norms, and perceived behavioral control, while attitudes and pro-environmental behavioral intentions are relatively similar across contexts. In urban areas, knowledge significantly influences risk perception, whereas attitudes, subjective norms, and perceived behavioral control predict pro-environmental behavioral intention. In rural areas, risk perception and perceived behavioral control are the main predictors, with no direct effect of knowledge. Conclusion: Overall, knowledge alone is insufficient to promote pro-environmental behavioral intention. Instead, behavioral intentions follow context-specific pathways, driven primarily by attitudinal and normative factors in urban areas and by risk awareness and perceived behavioral control in rural settings.
