The issue of plastic bags continues to be a significant topic globally in waste management. Their relatively low cost, ease of use, and accessibility have made plastic bags an integral part of human life. With increasing plastic bag usage, inevitably comes an increase in plastic waste. Moreover, the rapid usage cycle of plastic bags, as they are typically single-use items used only temporarily, exacerbates the problem. If plastic waste is not optimally managed, it will have negative environmental impacts. To address this, the retail company Alfamart has begun employing green marketing strategies to promote the "Plastic Bag Diet" by offering environmentally friendly shopping bag products (Eco Bags). This aims to raise awareness and concern among the public for environmental sustainability by reducing plastic bag usage during shopping. Apart from Alfamart, other competing retail companies have also adopted similar strategies and offer eco-friendly bag products. The intensifying competition among retail companies forces managers to reconsider their strategies to win market share. The issuance of the Bali Provincial Regulation on Limiting Single-Use Plastic Waste is based on Article 12 paragraph (3) and Article 13 paragraph (2) of Bali Provincial Regulation Number 5 Year 2011 concerning Waste Management. This reflects the negative impacts that can arise if waste is not properly managed. The enactment of local regulations prohibiting the use of single-use plastic indicates a legal policy direction towards environmental conservation. The research method used in this study is a juridical normative method with a literature review approach, focusing on legal norms including principles, norms, rules, regulations, agreements, and doctrines. Therefore, this study aims to analyze the effects of green marketing on attracting purchasing interest and persuading the public to make purchasing decisions on Eco Bag products at Alfamart as alternatives to plastic bags.

The World Food and Agriculture Organization (FAO) said that  one third of the food produced each year, amounting to 1.3 billion tonnes, is food waste. Food waste is food that is fit to be eaten before or after it has expired. Food waste is classified into two: food losse and food waste. food waste based on probability is probably avoidable waste, avoidable food waste, unavoidable food waste. Sampel for probably avoidable waste is breadcrump. But sampel for unavoidable food waste is solid  tofu waste. The problem of food waste that has a negative impact on health and the environment can be reduced by utilizing it through the right processing process so that. Reusing food waste will also provide economic value. One of the wastes that can be consumed again but must use a different processing   process is probably avoidable waste is the edge of bread that can be made into breadcrumbs, which is flour made from mashed dry bread and waste with the Unavoidable food waste category, for example, is tofu dregs that are reprocessed into tofu dregs flour.

 Agricultural waste is often underutilized, despite its significant potential as a raw material for environmentally friendly products. This study aims to develop bioplastics from corn waste by utilizing locally sourced enzymatic technology as the main catalyst in the biomass conversion process. Corn waste in the form of cobs and post-shelling residues was first prepared through drying, grinding, and mild chemical pretreatment to loosen the lignocellulosic structure. Subsequently, enzymatic hydrolysis was carried out using local enzymes derived from indigenous microorganisms, which decomposed cellulose and hemicellulose into monomeric sugars. The hydrolyzed sugars were then fermented into natural polymers, molded using the solution casting method, and dried to form bioplastic sheets. The results revealed that the produced bioplastics possessed mechanical properties comparable to commercial PLA, with tensile strength of 45–50 MPa, an elastic modulus of 2.5 GPa, and elongation at break of 5–7. Biodegradability testing showed that the material degraded up to ±85 within 90 days, exceeding the minimum threshold of 80% considered satisfactory. These findings confirm that corn waste can be transformed into competitive and eco-friendly bioplastics, while also highlighting the potential of locally based enzymatic technology for industrial-scale applications. The implications of this research extend not only to reducing waste and plastic pollution but also to strengthening the circular economy through the utilization of renewable agricultural resources.
