abstract
An investigation was carried out concerning the effects of Community Based Waste Management (CBWM)
systems on people’s attitude toward waste management within (Semarang City) Indonesia and the waste
flow in areas with CBWM, in order to identify its benefits and challenges.
A questionnaire survey was performed in Bukit Kencana Jaya (BKJ) where CBWM had been previously
implemented, as well as three areas currently practicing typical waste management: Graha Estetika (S1),
Banteng Selatan area (S2), and Genuk Sari area (S3). The results indicated less occurrences of inappropriate
waste handling behavior such as backyard burning and throwing waste on the road side or into the
river in BKJ, when compared with other areas employing traditional waste management. The crosscorrelation
analysis showed a strong relationship between the income levels in areas S1 and S3 and
people’s willingness to separate their waste together with a close correlation between education and
willingness to cooperate in S3.
From the waste flow analysis, it was found that a reduction in the order of 33% could be achieved in
household waste transported to landfill sites. In reality, however, the overall amount of waste delivered
to landfill sites has augmented due to increases in collected waste.
Compost market development and improvements in compost production are necessary to further
reduce landfill waste.
