Pengaruh Pengetahuan Mikroplastik, Persepsi Risiko, Sikap, Norma Subjektif, dan Kontrol Perilaku terhadap Niat Perilaku Pro-Lingkungan

Abstract

Pencemaran mikroplastik menjadi ancaman bagi kesehatan dan lingkungan. Ibu rumah tangga berperan penting dalam menentukan perilaku konsumsi terkait penggunaan plastik. Penelitian ini menganalisis pengaruh pengetahuan mikroplastik, persepsi risiko, sikap atas mikroplastik, norma subjektif, dan kontrol perilaku terhadap niat perilaku pro-lingkungan pada rumah tangga miskin dan tidak miskin menggunakan Theory of Planned Behavior (TPB) yang diperluas. Berdasarkan analisis SEM-PLS terhadap 568 ibu rumah tangga di Kabupaten dan Kota Bogor, ditemukan bahwa niat perilaku pro-lingkungan dipengaruhi oleh sikap, norma subjektif, dan kontrol perilaku, sedangkan sikap memediasi pengaruh pengetahuan mikroplastik dan persepsi risiko terhadap niat perilaku. Selain itu, terdapat perbedaan karakteristik dan kekuatan hubungan antarvariabel antara rumah tangga miskin dan tidak miskin. Temuan ini menunjukkan bahwa upaya meningkatkan niat perilaku pro-lingkungan perlu mempertimbangkan kondisi sosial ekonomi rumah tangga.

Microplastic pollution poses a threat to human health and the environment. Housewives play an important role in shaping consumption behaviors related to plastic use. This study examines the effects of microplastic knowledge, risk perception, attitudes toward microplastics, subjective norms, and perceived behavioral control on pro-environmental behavioral intention among poor and non-poor households using an extended Theory of Planned Behavior (TPB). Based on SEM-PLS analysis of 568 housewives in Bogor Regency and Bogor City, pro-environmental behavioral intention was influenced by attitudes, subjective norms, and perceived behavioral control, while attitudes mediated the effects of microplastic knowledge and risk perception on behavioral intention. In addition, differences in household characteristics and the strength of relationships among variables were observed between poor and non-poor households. These findings suggest that efforts to promote pro-environmental behavioral intention should consider households' socioeconomic conditions.
