Waste is become one of many environmental problems in Bandung, Indonesia, especially plastic waste. Every year, there is increasing trend of the need of plastic about 200.000 tons annually in the country. Taking focus of plastic bag waste, it poses real environmental impacts because of its characteristic of low degradability so it may cause flooding by clogging the drainage, polluting the ocean, and producing toxic gases when burned. The first method of 3R concept, reduce, is used in this study by implementing the provision of shopping bags so that waste can be reduced. This study aims to determine the effect of intervention on plastic bag waste reduction. There are six sites with three levels of economic differences. Intervention is given to the three sites, while others are not. Waste sampling carried out by two phases, phase I performed before intervention and phase II performed after the intervention is completed. Intervention contains provision of shopping bags and information related to plastic bags. The result, Bandung produces waste up to 2.16 litres/person/day or 0.40 kg/person/day with the average composition of the waste plastic bag is 5.66% from total waste. In detail, ccomposition of plastic bag waste in the upper class community is 7.45%, the middle class is 5.35%, and the lower class is 4.18%. Test of significance, t-test of plastic bag waste from phase I and phase II, shows that the intervention has a significant effect on plastic bag waste reduction. On average, shopping bag intervention approach successfully reducing plastic bag waste up to 35% in the study area.
