From Waste to Style: Denim Eco-Bags

Shopping bags play a crucial role in daily life, especially for carrying items when shopping for necessities like food, clothing, or other goods. In Indonesia, the use of single-use plastic shopping bags remains high. These plastics often end up in oceans, rivers, or landfills, causing pollution and harming ecosystems. This research aims to develop Denim Eco Bags (DECOBAG) from used denim, combining patchwork, smocking, and macramé techniques. The research method is a development study adopting the 4D procedure by Thiagarajan, Semmel, and Semmel, consisting of four stages: define, design, develop, and disseminate. The research data includes quantitative data collected through questionnaires distributed to users and qualitative data from interviews with main subjects. The results showed that the shopping bag made had excellent aesthetic value, with a percentage of 82%, excellent functionality value, with a percentage of 93%, and excellent suitability value, with a percentage of 88% after revision and modification. The results indicate that the shopping bag is aesthetically pleasing, functions well, and meets user needs after revisions and modifications. This study focuses only on aspects of functionality, aesthetics, and suitability perceived by users. Therefore, future research should focus on other quality aspects that have not been examined, such as durability against washing and sunlight.
