| Summary: | Municipal solid waste management is the most critical environmental problem in
Malaysia. The main purpose of this research was to explore the current
scenarios of intention to practise solid waste segregation-at-source among
households in Selangor; to evaluate the levels of attitude, subjective norms,
environmental concerns, environmental knowledge, and intention to practise
solid waste segregation-at-source; to investigate the relationships between
households’ attitude, descriptive norm, and injunctive norm with the intention to
practise solid waste segregation-at-source; as well as to ascertain the mediating
effect of environmental concerns and the moderating effect of environmental
knowledge between households’ attitude, descriptive norm, and injunctive norm
with the intention to practise solid waste segregation-at-source. A total of 400
residents living in the townships of the nine districts of Selangor were selected
via a multistage sampling method. A self-administrated bilingual questionnaire
was used to collect the quantified research data. The measurements were
adapted and adopted from different sources to examine the key variables in this
research. The results revealed that descriptive norm [p = 0.038 (p ≤ 0.05), r =
0.104] and injunctive norm [p = 0.000 (p ≤ 0.001), r = 0.317] have positive
relationships with the intention to practise solid waste segregation-at-source.
However, the results also revealed that there was an insignificant relationship
between attitude [p = 0.139 (p > 0.05), r = 0.074] and the intention to practise
solid waste segregation-at-source. Hence, it was excluded from the further
mediation and moderation test throughout the research. In terms of mediation
test, the egoistic concern [p = 0.001 (p ≤ 0.001), t = 3.182] as well as the
altruistic concern [p = 0.000 (p ≤ 0.001), t = 4.462] were found to mediate the significant relationship between injunctive norm and intention to practise solid
waste segregation-at-source. From the perspectives of moderation test, the
results postulated that environmental knowledge did not moderate the
relationships between descriptive norm [p = 0.511 (p > 0.05), t = 0.658] and
injunctive norm [p = 0.519 (p > 0.05), t = 0.645] with the intention to practise solid
waste segregation-at-source. The findings provide an insight for the Malaysian
citizens, governmental bodies, non-governmental organisations, and voluntary
bodies to strengthen the sense of responsibility to maintain the cleanliness of the
environment. The current research data, in particular, is able to provide a
direction to the Malaysian governmental bodies, including National Solid Waste
Management Department, Solid Waste Management and Public Cleansing
Corporation, Malaysian Ministry of Energy, Science, Technology, Environment
and Climate Change as well as Malaysian Ministry of Housing and Local
Government in their future policy planning and implementation. Instead of using
the ordinary self-administrative bilingual questionnaire, future research is
recommended innovating different mode of instrumentation to evaluate the
respondents' behavioural changes for creating a comprehensive understanding
of the solid waste segregation-at-source policy among Malaysian citizens. |
