The increasing amount of waste generation has caused many serious and complex problems in
many areas. Meanwhile, the existing waste management conducted by the community, i.e. ‘collect-carry-throw’ system can cause environmental problems. Therefore, it is necessary to look for
other alternatives that are more environmentally friendly, one of which is by waste bank system.
However, community participation in Bantul Regency in sorting and saving their waste in waste
banks is still low. It can be seen that only 10.28 % who sort and partially utilize their waste,
whereas 13.41 % sort and discard, and 76.31 % do not sort at all. The reason why they do not
sort the waste, respectively from the highest percentage is because of: lazy (40.56 %), do not
know that garbage must be sorted before disposed (33.33 %), do not have the facilities (11.79
%), unprofitable (10.48 %), and there is no regulation (3.92 %). The purpose of this study was to
know the relationship between knowledge and attitude of the society in waste management
based on Waste Bank system in Bantul Regency. The study was an observational analytic research with purposive sampling. From the selected 127 respondents, the result of statistical analysis by using Spearman correlation test, obtained p-value < 0.001, and a correlation coeffcient
of 0.433. So, it can be concluded that there is a significant correlation between knowledge level
and attitude of community in in terms of waste managemen through Waste Bank approach, and
the correlation has medium strength.
