Plastic waste knowledge of households towards a sustainable environment

Abstract

Plastic waste in Malaysia has become a serious problem since it affects not only the environment but wildlife animals and marine life too. These may cause by irresponsible people in dealing with their plastic waste management. Therefore, this study is conducted mainly to analyse the knowledge, attitude, awareness, and behaviours of households in Pasir Gudang towards plastic waste management in separating plastic waste before its disposal. A questionnaire was distributed among households who live in this area. The Binary Logistic Regression is used to analyse the knowledge, attitude, awareness, and behaviour of households towards plastic waste management. The results show that only the behaviours of households affect the plastic waste management in their households (p-value=0.04). The Hosmer-Lemeshow test indicates the model has a good fit for the data (p-value=0.480). Other than that, the Omnibus test (p-value=0.03) shows predictors have significant effects and gave improvement to the model. The Classification Table shows the accuracy of 67.4% of the households who separated plastic waste before its disposal. It is suggested to improve the result by adding more respondents to provide insight information on the independent variables, analyse further using other approach such as decision tree and parallelly acknowledge others on the importance of recycling plastic waste.

Estuary Clean Up dalam Mendukung Pengelolaan Kawasan Pesisir Desa Sungai Nibung Kalimantan Barat

“…Tingginya akumulasi sampah di lokasi kegiatan dipengaruhi oleh beberapa faktor, antara lain kondisi geografis Desa Sungai Nibung yang memiliki banyak aliran sungai dan parameter lingkungan seperti arus dan gelombang yang dapat membawa sampah plastik. Selain itu, sampah hasil kegiatan manusia (Setyaningsih et al, 2023), seperti rumah tangga (Singh dan Sharma et al, 2023;Nasir et al, 2023) dan aktivitas perikanan komersial (tangkap dan budidaya) (Toyoshima, 2021;Skirtun et al, 2022) yang tidak dikelola dengan baik memberikan sumbangsih tinggi terhadap pencemaran plastik di lingkungan perairan dan pesisir. Alat tangkap seperti tali pancing, jaring, perangkap dan tali monofilamen yang hanyut maupun dibuang dapat menyebabkan dampak negatif terhadap biota akuatik (Parga-Martínez et al, 2020), seperti pertumbuhan, respon imun, fertilitas dan reproduksi, serta perubahan fungsi sel tergantung pada tingkat paparan sampah plastik (Prokić et al, 2019).…”
