Abstract

The increase in waste generation which is not accompanied by adequate provision of waste treatment facilities and only depends on conventional waste collection - collect, transfer, dispose- causing an immense accumulation of untreated waste on TPA Temesi (Temesi Final Disposal). Based on waste generation projection, on 2040 the total waste generation in Gianyar Regency was approximated about 1208,88 m3/day from a total occupant of 593.436 inhabitants in Gianyar Regency. The existing supporting capacity of TPA Temesi was 15.450 m3 meanwhile the total waste generation in Gianyar Regency on 2020 is up to 146.356 m3 consequently it is no longer a surprise if TPA Temesi was overloaded by untreated solid waste since 2020. In order to reduce waste generation and decreasing treatment burden in TPA Temesi, solid waste management using 3R method from household cluster needs to be applied. Using 3R concept, eventually the waste generation that disposed into TPA Temesi can be reduced significantly by 47%, from 1208,88 m3/day into 634 m3/day with total weight of 148 tonne/day on 2040. Within the 3R waste management from households, the land requirement could be reduced into only 1,54 Ha on 2020 and 20 Ha on 2040 from previously about 3 Ha and 39 Ha respectively.
